Pass Permitting Reform. Unleash American Solar and Storage.
A year ago, the Department of the Interior added new permitting reviews for solar and storage projects built on federal land or needing federal right-of-way approval. Every one of these projects now needs multi-step, Secretary-level sign-off, which is slowing down construction at a time when electricity demand is rising fast. The solar industry group SEIA estimates more than 450 planned projects, representing over a third of new power capacity in the pipeline, are now at risk. The slowdown has a price tag. A study from the Corporate Energy Buyers Association and NERA found that restricting new solar and wind development could add $81 billion to household electric bills over the next seven years, plus $40 billion more for businesses. Separately, Wood Mackenzie estimates more than $121 billion in planned solar and storage investment is at risk because of the added permitting uncertainty, which also threatens local jobs and tax revenue. For homeowners, this is less about immediate rebates or upgrades and more about the electric grid you rely on. Solar and battery storage are among the fastest sources of new power to bring online, and slower permitting means fewer of these projects reaching the grid as demand climbs from data centers, factories, and extreme weather. The solar industry is pushing Congress to pass permitting reform to speed up approvals across energy types. Nothing here changes home rebate programs or eligibility, but the pace of new solar and storage construction nationally could affect electricity prices and grid reliability in the years ahead.
East Coast States Will Sue Trump for Illegal Payoffs
Eight state attorneys general — from Connecticut, Delaware, Maine, New Jersey, New York, Rhode Island, and Vermont — have filed notice that they plan to sue the Trump administration over payments made to energy companies to cancel offshore wind projects. The administration paid the companies Bluepoint and Invenergy nearly $1 billion each, close to $2 billion total, in exchange for dropping their wind projects and shifting focus to fossil fuels. California's attorney general has filed a separate notice of intent to sue over the same deals, and a group of New England states is challenging a similar settlement involving the company TotalEnergies. The canceled projects would have supplied power to nearly 3 million homes across New York, New Jersey, and New England. The states argue the payoffs are illegal and part of a broader pattern of the administration working against renewable energy, including stop-work orders and cuts to federal clean-energy funding. For homeowners in the affected states, this mainly matters as a long-term regional power supply question rather than something with an immediate effect on your household. Offshore wind was expected to add electricity capacity to the grid in the Northeast; if those projects stay canceled, that supply won't materialize, which critics say could keep pushing electricity costs higher. The lawsuits could take time to play out, and it's not yet clear whether the projects would be revived if the states succeed. If you live in one of these states, it's worth keeping an eye on how this affects regional electricity prices over time.
Every Day In Every Way, Attribution Science Is Getting Better & Better
A new report from the National Academies of Sciences, Engineering, and Medicine finds that scientists have gotten much better at answering a specific question: how much did climate change contribute to a particular heat wave, storm, or flood? This field, called attribution science, compares what actually happened in an extreme weather event to what would likely have happened in a world without human-caused warming. The report says confidence is highest for heat waves, cold snaps, and large-scale heavy rainfall events, similar to the recent flooding in Texas. Confidence is lower for tornadoes, hail, and other small-scale storms that are harder to model. This matters to homeowners mainly as background context rather than a program or deadline. Better attribution science is showing up in lawsuits against oil and gas companies, including a $50 billion case in Oregon that cited a study on a 2021 Pacific Northwest heat wave. It could also shape how insurers, local governments, and building codes think about flood risk, extreme heat, and storm damage in specific regions over time, though this report itself does not set any new rules or funding. There is no new rebate, incentive, or program tied to this report, and no action for homeowners to take right now. It is worth knowing as one more sign that extreme weather in your area, whether flooding, heat, or wildfire smoke, is increasingly being tied to climate change with real scientific rigor, which may eventually influence local risk assessments, insurance, and building standards.
New York governor orders first statewide data center moratorium
New York Governor Kathy Hochul has ordered a pause on new large-scale data centers, the first statewide moratorium of its kind. The order stops the state from issuing new permits for these facilities for up to a year, while regulators study how data centers affect the power grid and study whether to make data centers pay more for their electricity or supply their own power instead of drawing on the shared grid. The move comes as data centers, built to handle growing computing demand from artificial intelligence, have raised worries about rising electricity bills and strain on power supplies. Hochul cited those concerns directly, saying data center growth threatens to push up utility costs for New Yorkers. Separately, state lawmakers passed their own, broader data center moratorium last month, but Hochul has not said whether she will sign it. Hochul also asked the state's economic development agency to create a framework local communities can use when negotiating with tech companies over new data center projects, covering things like infrastructure upgrades, child care investment, direct payments, and wage standards. She announced plans for a fund that would require data centers to help pay for grid upgrades and clean energy, and asked lawmakers to end the state's sales tax break for large data centers. For homeowners, this doesn't change anything immediately, but it signals that New York is treating data center growth as a factor in electricity costs and grid reliability, issues that also shape rebates and incentives for home energy upgrades. Other states may watch how this plays out.
Bosch Introduces Line of Portable Home Dehumidifiers
Bosch Home Comfort has launched its first line of portable dehumidifiers for U.S. and Canadian homes, called the Dry Series. It comes in two models aimed at different room sizes. The Dry 2000 pulls up to 22 pints of moisture a day and covers spaces up to 1,500 square feet, with a 1.5-gallon water tank that has a viewing window and an option for continuous drainage instead of manual emptying. The Dry 4000 handles larger areas, removing up to 35 pints a day across up to 3,000 square feet, and adds wheels for moving it between rooms. Both units are meant for basements, bedrooms, and living areas where excess moisture can be a problem. They include three operating modes: an automatic mode that adjusts fan speed to hold humidity between 40% and 70% (55% is the default) and saves energy once that level is reached; a quiet night mode that slows the fan and turns off lights for sleeping; and a turbo mode that runs the fan at full speed to dry out a heavily damp room quickly, showing real-time moisture readings as it works. For a homeowner dealing with a damp basement, musty smells, or humidity that affects comfort and indoor air quality, this gives a new option to consider, with a size to match either a single room or a larger multi-room space. No pricing or availability date was included in the announcement.
Endgame: The Decline & Fall of the Western Automotive Industry
Traditional car makers are struggling as Chinese electric vehicle brands gain ground worldwide. Toyota's global CEO recently warned his own supplier network that the company "will not survive" without major changes, pointing to inefficiencies like producing 70,000 different wiring harness variants. Meanwhile Volkswagen's board rejected its CEO's plan to cut factories and jobs, even though the company is making more cars than it can sell and profit margins are shrinking. Analysts quoted in the piece argue both companies are missing the real problem: they're slow to commit fully to electric vehicles while Chinese brands like BYD move faster. BYD, one of China's largest EV makers, says it's thriving even without access to the US market, citing strong demand in Australia, Brazil, the UK, and Europe. In Australia, BYD has already become the second-largest car supplier and expects to outsell Toyota by 2030. Company executives say demand now outpaces what they can supply. Tariffs meant to slow Chinese EV imports appear to be having some effect in the US, but data cited in the piece suggests they aren't working the same way in the European Union. For homeowners, this doesn't change any rebate or program details, but it's a sign of how fast the EV market is shifting globally. If you're weighing an electric vehicle alongside home upgrades like a heat pump or EV charger, it's worth knowing the vehicle market itself is in flux, with more competition and options likely on the way, even if US availability of certain brands remains limited for now.
Trump’s dumb idea to tariff Canada over smoke could set a useful precedent
This piece is a commentary on national politics and trade policy, not an energy-upgrade story, so there's nothing here that changes what you'd do to your own home. The background: wildfire smoke from Canada has been drifting into the eastern and midwestern US this summer, driven by the same heat waves fueling similar fires across the US and Russia. In response, President Trump and congressional Republicans have floated tariffing Canada over the smoke, rather than addressing the climate change that's making wildfires more frequent. The writer argues the tariff idea is misguided as policy, but says the underlying concept — charging for pollution that crosses borders — is actually the basis for real climate tools like carbon pricing and "carbon border adjustment mechanisms," which are essentially tariffs on carbon emissions. The EU has already adopted one, and California and Quebec link their cap-and-trade carbon markets. A recent global proposal from economist Thomas Piketty's research group suggested that countries could collectively tax imports from high-polluting nations like the US and China even without their cooperation, based on the damage that pollution causes. None of this involves a new program, rebate, or deadline for homeowners. It's a discussion of trade and climate policy at the international level, with no direct bearing on home energy upgrades or incentives available to you right now.
This New Made-In-China Ship Explains Why Offshore Wind Will Crush Trump’s Coal Dreams
A Chinese shipyard has delivered a new offshore wind installation vessel called Wind Ace, built for the Danish company Cadeler. The ship is designed to install the newest, supersized wind turbines and their foundations more quickly and cheaply than older equipment, which was originally borrowed from the oil and gas industry. Wind Ace will soon head to Scotland to help build the East Anglia TWO wind farm, installing 64 turbines. Cadeler now has 11 of these specialized vessels, with a 12th on order. The bigger story is cost. New offshore wind projects worldwide are reportedly reaching $40 to $50 per megawatt-hour, putting them in the same range as natural gas and cheaper than new coal plants. The U.S. Department of Energy has projected similar declines, driven by larger turbines, better construction ships, and cheaper operations and maintenance through sensors, drones, and underwater robots that cut down on costly boat trips and labor. None of this touches home energy bills directly right now, and it has little to do with rooftop solar or home upgrades. But it matters for the country's power mix over time: if offshore wind keeps getting cheaper than coal and gas, it could shape what fuels the electric grid you draw from in the years ahead, even as U.S. offshore wind projects face political headwinds and legal fights over canceled leases and funding.
Honda goes all-in on EVs in a multibillion dollar market: commercial lawnmowers
Honda has started shipping an all-electric, self-driving riding mower aimed at commercial landscapers, not homeowners shopping for a backyard mower. The ProZision Autonomous ZTR (zero-turn radius) is built at Honda's plant in North Carolina and priced at just under $33,000. It runs on a 48-volt battery system with five electric motors, and it can "learn" a property's layout after one manual pass, then mow that route on its own using GPS, radar, and other sensors, reproducing the path within about 1.25 inches of accuracy. This is a professional tool, not a consumer product, but it points to a broader shift that could touch homeowners indirectly. More than 100 U.S. cities and counties have already restricted or banned gas-powered landscaping equipment, and noise rules in many other areas are pushing contractors toward battery power. If you hire a lawn or landscaping service, you may start seeing quieter, electric equipment show up at your house as companies replace gas mowers to meet these local rules or cut labor costs. Honda mentions that some local utilities or governments may offer tax incentives for this kind of equipment, though details depend on where you live and would need to be checked with a dealer. For now, there's no announced consumer version of this mower, so the direct impact on a typical homeowner's own equipment purchases is limited.
EVs At 98.3% Share In Norway – Tesla Model Y Leads
Electric cars now make up nearly all new car sales in Norway. In the second quarter of 2026, plug-in electric vehicles reached 98.1% of new car sales there, up from 96.7% a year earlier. Fully electric cars (BEVs) alone hit 97.4%, while plug-in hybrids fell to just 0.6%. Gas and diesel cars, along with regular hybrids, now account for only about 2% of new sales in Norway, and that sliver is expected to shrink further by year's end. The Tesla Model Y was the top-selling electric model, followed by new entries from Toyota. This is mostly a story about how far along Norway is in switching to electric cars, not a US or general homeowner policy update. Norway offers a tax break that exempts cheaper electric cars from a value-added tax, but that exemption only applies to vehicles priced under a set cap, which the country lowered this year. That price cap shift shaped some of the sales activity, including a temporary re-release of Kia's Niro model to fit under the new threshold before it's discontinued. For US readers, the news doesn't change any American rebate or purchase program. It's a snapshot of a market where electric vehicles have essentially become the default choice, offering a preview of how EV adoption can look once prices, charging speed, and model variety mature.
LiuGong brings electric heavy equipment options to North America [video]
This news is about heavy equipment, not home upgrades, but it's a sign of where electric technology is heading. LiuGong, a Chinese equipment maker, has launched battery-electric construction machines in the US and Canada, including wheel loaders, an excavator, and a large reach stacker used at ports and rail yards. The company says it has over 15 years of experience with electric equipment and more than 60,000 electric machines already working worldwide. LiuGong claims its electric machines cost 40% to 50% less to run than similar diesel equipment, due to lower fuel, maintenance, and parts costs. The battery packs and motors come with a warranty of five years or 10,000 hours of use. The company also plans to bring electric forklifts, warehouse equipment, and other material handlers to North America over the next year and a half. None of this involves home energy equipment or rebates, so it has no direct bearing on heat pumps, weatherization, or other residential upgrades. It's worth knowing about mainly as a sign that battery-electric technology is expanding into heavy industrial equipment, following the same cost and maintenance logic that's driving electric options in homes and vehicles.
Philippines Energy Company Junk Coal Plant & Break Ground on Latest BESS
In the central Philippines, energy company Aboitiz Power is tearing out old coal and diesel units and replacing them with giant batteries. On July 1, it broke ground on a 60-megawatt battery storage system in Naga, Cebu, built on the site of a coal plant from the 1980s that has now been fully demolished. The battery, with 120 megawatt-hours of capacity, will store extra power when demand is low and release it within milliseconds when supply drops, acting as a backup for the grid. It's expected to be running by October 2027. A separate 30-megawatt battery near Lapu-Lapu City is also nearly finished and awaiting approval to go online. This is part of a much larger shift in the region. The Philippine government has ordered energy companies to add at least 170 megawatts of battery storage across the islands of Cebu, Negros, and Panay, and regulators are currently reviewing 17 more storage project applications. Aboitiz alone now has more than 10 battery projects in various stages across the country, including sites in Mindanao and Luzon, some paired with existing hydroelectric dams. Other companies are moving too: Meralco PowerGen recently switched on a 25-megawatt battery in western Cebu using advanced lithium-ion cells. None of this is a program homeowners in the US can tap into, but it shows how utilities elsewhere are using large batteries, rather than new fossil fuel plants, to keep the lights on as more solar and wind power comes online.
Radar EV Pickup Sales More Than Double in Philippines as Electric Trucks Gain Traction
This one is about vehicles, not home upgrades, so it won't affect your energy retrofit plans. But here's what happened: electric pickup trucks are picking up sales in the Philippines. UAAGI Auto Group, which distributes the battery-electric Radar RD6 pickup there, sold 112 units in June, more than double the 44 it sold in May. Other electrified pickups are also gaining ground in that market, including the plug-in hybrid BYD Shark 6 and a Dongfeng electric truck. The RD6 starts at roughly $25,230 for its base version and can travel up to 443 kilometers on a charge, or over 1,000 kilometers combined in its plug-in hybrid form. One feature worth noting: it can supply up to 3.5 kilowatts of power through outlets built into the cabin and cargo bed, enough to run tools or appliances without a separate generator. That kind of vehicle-to-load capability is starting to show up in electric trucks more broadly, and it points to a future where an EV in the driveway could double as backup power during an outage. Nothing here changes what's available to US homeowners today, and none of these trucks are sold domestically. But it's a sign of where electric truck technology is headed globally, including power-sharing features that could eventually matter if you're weighing an EV as part of your home's backup power or electrification plans.
Philippine Science Department Expands Academic Partnerships to Push EV Adoption
The Philippines is pushing to scale up electric vehicles built by its own universities and researchers, as unstable fuel prices squeeze the transport sector. The Department of Science and Technology is moving several homegrown projects from lab testing into real-world use, including the M/B Dalaray, the country's first domestically built electric passenger ferry, now running on Manila's Pasig River with fast-charging stations at its terminals. On land, electric tricycles are also part of the push: the standard E-Trike has finished trial runs in several regional cities, while the C-Trike, a kit that converts existing gas tricycles to electric, is heading toward mass production. Field data cited by the agency puts the C-Trike's running cost at 0.88 pesos per kilometer, versus 2.30 pesos for a conventional gas tricycle. Other projects include a 23-seat electric jeepney built to meet the country's public transit modernization rules, a hybrid electric train being tested with the national railway, and a fast-charging system called CharM that cuts charging time from six hours to about 30 minutes. That charging network is expanding beyond Manila to island provinces, with new solar-powered stations planned for Romblon. None of this is available in the US, and there's no rebate or program here tied to it. For a homeowner, it's mostly a signal of where global EV and charging technology is heading, particularly the emphasis on fast charging and low-cost retrofit kits, ideas that eventually show up in other markets, including the one you shop in.
HERO’s Mission: Building a Blueprint for Wave Energy Components
Researchers at the National Laboratory of the Rockies have been refining a device called the HERO WEC, which uses wave energy to desalinate seawater. It works by pumping seawater through an onshore filtration system, powered either hydraulically or electrically. The team has now redesigned a key electrical part called the charge controller, which regulates how power flows from the wave-powered generator into a battery bank, protecting the batteries from overcharging. The original charge controller used standard parts built for steadier energy sources like solar, but ocean testing showed they couldn't handle the choppy, irregular surges of wave power. So the team built a custom version instead. In lab tests simulating ocean conditions, the new charge controller captured up to eight times more power than the original design, meaning the device can charge its batteries more reliably and produce more desalinated water. This isn't a product homeowners can buy or install. It's early-stage research funded by the Department of Energy, aimed at building a reusable design that other wave-energy developers can adapt for their own devices, potentially speeding up progress across the industry. The next step is testing the new charge controller alongside the generator and batteries as a full system, simulating wave conditions before moving back to real ocean testing. For now, this is a research milestone in wave-powered desalination technology, not something tied to home energy upgrades or rebates.
New Delhi Air Pollution Index Further Pushes for EV Adoption in India
Delhi has approved a major new electric vehicle policy aimed at cutting the smog that regularly chokes the city, especially in winter, when vehicle exhaust, crop burning, construction dust, and industrial emissions combine to push air quality into "very poor" or "severe" territory. The plan puts about $1.75 billion (₹15,000 crore) toward electrification over four years. Owners who scrap an eligible gas-powered passenger vehicle bought before April 1, 2020, and replace it with an electric model can get an incentive of roughly $1,060 (₹100,000). Electric cars priced up to ₹3 million will skip road tax and registration fees, and electric scooters and motorcycles get purchase incentives during the initial rollout. Starting in 2028, new gas-powered two-wheelers can no longer be registered in Delhi, and new auto rickshaws must be electric. The city also plans more than 30,000 public charging points. This is a India-specific, city-level policy — it doesn't apply to homeowners elsewhere, but it's part of a broader pattern of governments pairing EV incentives with clean-air goals. Environmental researchers have welcomed the two- and three-wheeler phaseout as potentially significant, since those vehicles make up most of Delhi's traffic. They caution that success depends on how fast charging stations get built and whether EVs stay affordable, particularly for lower-income drivers who currently own the oldest, most polluting vehicles. Nationally, India's PM E-DRIVE program already offers manufacturer-side rebates that lower EV purchase prices, covering two- and three-wheelers, buses, ambulances, and trucks, and has reportedly supported over 2.8 million electric vehicles so far, including funding for more than 14,000 electric buses.
New HMP Flash brings affordable 75 MPH electric scooters to the US
This one's outside the home energy world Retrofit Relay usually covers, but here's what's new: a San Francisco company called HMP Bikes has released the HMP Flash, an electric scooter aimed at US buyers who want something between an e-bike and a full motorcycle. It tops out at 75 mph and gets a real-world tested range of 70 miles, with HMP saying that figure came from actual city riding rather than optimistic lab numbers. The Flash comes with a removable battery, available as a single pack (3.3 kWh) or dual pack (6.6 kWh total, needed to hit the 70-mile range). Buyers can add a 2 kW onboard charger that uses a J1772 plug and takes the dual-battery version from 20% to 80% in about two hours, or charge the batteries off the bike with an included 840-watt plug-in charger. Standard features include ABS brakes, traction control, Apple CarPlay and Android Auto, a dash cam, keyless start, and a cargo rack. Because of its speed, California registers it as a motorcycle, meaning riders there need a motorcycle license and DOT-approved helmet — rules elsewhere may differ. Pricing starts at $4,799 for the single-battery model without the onboard charger and goes up to $5,999 for the dual-battery version with the charger included. That's notably cheaper than the BMW CE04, one of the few other highway-capable electric scooters sold in the US, which costs close to $13,000.
Philippines Logistics Firm Sees Swappable Battery Scooters As The Next Milestone In Last-Mile Deliveries
A delivery company and a mobility startup in the Philippines have started testing electric scooters with swappable batteries for package deliveries in Metro Manila. JRS Express, a courier service, is running the pilot with Voltai, which leases out electric motorcycles and batteries on a monthly subscription instead of selling them outright. This lowers the upfront cost for delivery riders and fleet operators, who normally rely on gas-powered motorcycles and face high fuel and maintenance costs. The scooters run on two batteries that together provide about 140 kilometers of range. When a rider runs low, they pull into one of 15 swap stations around Metro Manila, trade their depleted batteries for charged ones in under a minute, and get back on the road without waiting to plug in and recharge. A mobile app tracks battery health, vehicle location, and usage for fleet managers. Early results from the pilot show the system running smoothly, with riders reporting satisfaction so far. This is a commercial fleet story rather than a personal-vehicle one, and it's happening overseas, so it has no direct bearing on home energy upgrades or rebates. The interesting wrinkle for anyone tracking the broader shift to electric transportation is the charging approach: because delivery scooters run on predictable schedules, the swap stations can draw power steadily during off-peak hours, avoiding the sudden demand spikes that come with fast-charging car fleets. Voltai and JRS Express have not said how many scooters are in the pilot or when the service might expand beyond this trial.
HVAC Trade Groups Back Bill to Change Regional Efficiency Compliance
A bill in the Senate would change how energy efficiency rules work for regional heating and cooling equipment, like furnaces, central air conditioners, and heat pumps. Right now, whether a unit meets a region's efficiency standard depends on the date it's installed in a home. Under the proposed bill, called the SMART Energy Efficiency Standards Act, that would switch to the date the equipment was manufactured instead. The change matters because efficiency standards sometimes tighten over time, and equipment made before a new standard took effect can currently become impossible to install once the deadline passes, even if it was legally built and sold. Four major HVAC trade groups back the bill, arguing it would prevent this "stranded inventory" problem and match how most other federal efficiency programs already work. For a homeowner, this is mostly a behind-the-scenes rule about how manufacturers, distributors, and contractors handle compliance paperwork and inventory during a standards transition. It does not change what efficiency level your furnace, AC, or heat pump needs to meet, and it does not affect any rebate program. If you happen to be replacing a system right around the time a new regional standard takes effect, this kind of rule could affect which units are still available for installation, but the bill itself is still in the Senate Committee on Energy and Natural Resources and has not become law.
Helping school districts navigate IAQ legislation in Virginia
Virginia recently passed a law requiring school boards to meet specific indoor air quality (IAQ) standards in public school buildings. To help districts understand and comply with the new rules, the Center for Green Schools and the Virginia School Plant Management Association held a daylong conference in Hampton on June 8. Staff from 43 school districts, about a third of the state's total, attended sessions on the new legal requirements, HVAC systems, ventilation, and how to balance air quality with energy use. This is industry and school-facilities news rather than something with a direct action for individual homeowners. But it points to a broader trend worth knowing about: districts like Prince William County and Caroline County Public Schools are shifting from fixing air quality problems building by building to tracking ventilation, air quality, and thermal comfort across their entire portfolio of schools using data. Advocates say this approach lowers operating costs, reduces health risks, and can even improve student attendance and academic performance. For families, the takeaway is mostly informational: if you live in Virginia, your local school district may soon be evaluating or upgrading ventilation and filtration systems under this legislation. The Center for Green Schools also offers a free toolkit with templates and guidance on 20 IAQ components, from building assessments to filtration and staff training, which district staff can use regardless of state. Virginia school staff can contact the center directly for more support, and VSPMA holds its next conference in October in Blacksburg.
Biden’s climate law is dead. The energy transition might not be.
Last year's "Big Beautiful Bill" repealed most of the tax credits from the 2022 Inflation Reduction Act, which had offered incentives for solar and wind power, EV battery factories, electric cars, and heat pumps (electric heating and cooling systems). A year later, the effects are mixed. The repeal has scrapped dozens of planned solar farms and battery plants and wiped out more than 250,000 jobs in the electric vehicle sector, according to a report from the business group E2. But it hasn't stopped the clean energy shift entirely. A new MIT study found that about 75 percent of the solar and wind power expected under the old law will still get built, because much of it is now profitable without subsidies. Rooftop and large-scale solar have held up especially well, with more than 80 percent of projected solar still moving forward. Onshore wind has fared worse, with about half of expected projects at risk. Meanwhile, demand from AI data centers is pushing tech companies to sign large deals for wind and solar power anyway, which is helping offset some of the losses. For homeowners, this means federal incentives for things like solar panels, heat pumps, and electric vehicles have shrunk substantially compared with two years ago. Some state-level rebates and programs may still exist, so it's worth checking what your state currently offers before assuming nothing is available. Experts say the broader path to cutting national carbon emissions has slowed and will likely take longer than it would have otherwise.
Why did energy-saving tips disappear from the Energy Department website?
The Department of Energy has quietly deleted more than 1,600 pages from its Energy Saver website, a resource homeowners used for tips on cutting utility bills and pollution. By July 3, two useful pages disappeared: one on doing your own home energy assessment (checking for air leaks, weak insulation, and inefficient lightbulbs), and one that helped people find a professional to do that assessment. Other lost pages covered shopping for efficient appliances, installing "cool roofs," and DIY energy-saving projects. Over 300 of the pages had drawn 160,000 views in the 30 days before removal, during a summer of heat waves. The timing raised questions. The pages vanished around the same time New York City's mayor urged residents to set air conditioners to 78 degrees during a heat wave, advice that mirrored guidance the DOE itself used to post (keeping thermostats between 75 and 78 degrees). The deletions also came right after the agency proposed a rule making it harder for future administrations to set efficiency standards for household appliances. The DOE has not explained why the pages were taken down, and information specific to its appliance standards program remains online. For homeowners, the practical effect is that a free federal guide to spotting energy waste in your house and finding an assessor is no longer available on the government's site. The change fits a broader pattern of federal agencies pulling consumer-facing climate and energy information from public view this year.
US will investigate solar cells from Ethiopia for potential tariff circumvention
The U.S. Department of Commerce is opening an investigation into whether solar cells shipped from Ethiopia are a workaround for existing tariffs on Chinese solar goods. American solar makers, including First Solar, Qcells, Silfab and Suniva, requested the probe in May, arguing that two Ethiopian manufacturers, Toyo and Origin Solar, are using Chinese-made wafers to produce cells in Ethiopia, then assembling them into modules in Ethiopia or Vietnam before shipping to the U.S. The companies say nearly 70% of these finished modules contain parts and processing already covered by long-standing anti-dumping and countervailing duties on Chinese solar products. Imports of Ethiopian solar cells and modules didn't exist before July 2025 but hit $277 million in just the second half of that year and have kept rising in 2026. Commerce expects a preliminary decision by December 10, 2026, and a final ruling around May 10, 2027. In the meantime, U.S. Customs will keep holding these imports in a special status and apply deposit rates as if the tariffs already applied, meaning duties could later be charged retroactively back to when the investigation began. This is the fifth such circumvention investigation into countries accused of relabeling Chinese solar components, following similar cases involving India, Indonesia and Laos. For homeowners, this doesn't change anything immediately, but it's part of a broader pattern of tariff enforcement that could affect solar panel pricing and availability over time.
Amended Complaint Filed in HVAC Price-Fixing Lawsuit
A lawsuit accusing major HVAC manufacturers of price-fixing has grown bigger. Plaintiffs — 39 homeowners and other buyers who say they paid inflated prices for heating and cooling equipment since January 2020 — filed an updated, 191-page complaint against Bosch, Trane, Carrier, Daikin, Lennox, Rheem, and AAON. The core claim is unchanged: that these companies violated federal antitrust law by coordinating price increases instead of competing independently. The manufacturers deny the allegations. The new filing adds detail rather than new claims. Plaintiffs now argue the alleged price coordination is ongoing, not just something that happened in 2020. They also point to subscription data services, like Pricefx and Convergence Data, that they say gave manufacturers detailed pricing information that could have made coordination easier. Another new section argues the companies had shared reasons to raise prices together, pointing to the pandemic, the switch to refrigerants with lower global warming potential, and updated efficiency rules as pressures that pushed manufacturers toward higher prices on new equipment. The complaint also highlights public statements on earnings calls and at industry events as possible signs of price signaling among competitors. The case is still in its early stages, and no court has ruled on whether any of this happened. Manufacturers are expected to seek dismissal, arguing their pricing moves were simply normal, independent business decisions. Plaintiffs are seeking money damages, including three times actual damages as allowed under antitrust law, plus legal costs. For homeowners who bought HVAC equipment in the past six years, this is a case worth watching, though it will likely take time before anything is resolved.
An ex-NREL scientist is using AI to bypass high-pressure solar sales reps
A new tool aims to take some of the guesswork out of buying rooftop solar. AgentSolar AI, started by a former National Renewable Energy Laboratory and First Solar researcher, works like an automated advocate for homeowners shopping for a solar system. The founder estimates that U.S. homeowners overpaid by about $2 billion in 2025 compared to fair market prices, largely due to "soft costs" like commission-heavy sales tactics that can add 30 to 40 percent to a system's price. On an 8 kW system, aggressive customer acquisition alone (door-knocking, purchased leads, sales pressure) can tack on $4,000 to $6,000. The platform can read a full solar proposal, pull out the pricing details, and compare them against market data to flag whether you are getting a fair deal. It also checks the installer's history and reviews. If you decide to move forward, the tool can draft counteroffers and send negotiation emails on your behalf, going back and forth until it judges the price is fair, then tells you the contract is ready to sign. A person still reviews each message before it goes out. The bigger goal is to shrink the sales and marketing costs baked into solar pricing, which the founder argues mainly benefit large national installers over smaller local ones who do good work but can't compete on advertising. He predicts that within five years, AI tools could handle much more of the process, from modeling your roof for solar potential to monitoring the system after installation.
1976: Legionella Reads Its Ugly Head
This is a history piece, not a current news story, but it explains where a term you may have heard — Legionnaires' disease — actually comes from, and why it matters for buildings with cooling towers or large air conditioning systems. In July 1976, people attending an American Legion convention at a Philadelphia hotel started getting sick with what looked like a bad cold that turned into pneumonia. Within weeks, 221 people were ill and 34 had died. Investigators eventually traced the cause to the hotel's cooling tower and air conditioning system, where a previously unidentified bacterium, later named Legionella pneumophila, had grown in warm water and spread through the air. It took the CDC six months to identify the bacteria, and the connection to the outbreak was announced in January 1977. This was the first documented case linking the bacteria to cooling towers, and it changed how the HVAC industry thinks about air conditioning equipment — not just as machines that cool air, but as systems that can affect indoor air safety if not maintained. Legionella grows in warm water, roughly 77 to 113 degrees Fahrenheit, which is why cooling towers became a focus of routine cleaning and water treatment. Formal industry standards took decades to arrive: a best-practice guide came out in 2000, and a required water management standard for qualifying buildings wasn't adopted until 2015. This history mostly concerns large commercial cooling towers rather than typical home air conditioners, but it's the origin of a health and maintenance issue still relevant to any building with a cooling tower system.
1976: Legionella Rears Its Ugly Head
In 1976, a mysterious respiratory illness struck 221 people and killed 34 after a Pennsylvania American Legion convention at Philadelphia's Bellevue-Stratford hotel. It took the CDC six months to identify the cause: a new bacterium later named Legionella pneumophila, which had grown in the hotel's cooling towers and spread through the building's air conditioning system into hospitality suites where conventioneers gathered. This was the first documented outbreak of what's now called Legionnaires' disease, and it changed how the HVAC industry thinks about cooling towers, the large units that reject heat from air conditioning systems, often on rooftops. Legionella bacteria grow naturally in warm water between 77 and 113 degrees Fahrenheit, conditions cooling towers can provide if not properly maintained. After 1976, engineers began pushing for routine cleaning and water treatment in these systems. Formal standards took decades to arrive: ASHRAE published best-practice guidance in 2000, and a real standard requiring water management programs for qualifying buildings didn't arrive until 2015. For homeowners, this history mainly concerns large commercial cooling towers rather than typical residential air conditioning equipment, which doesn't use the same water-based cooling process. Still, it's the reason building air conditioning is now understood as something tied to indoor air safety, not just comfort, and why commercial systems near you may have water treatment and maintenance requirements behind the scenes.
Clean energy still beats fossil fuels on cost, despite, well, everything
A new report from investment bank Lazard finds that wind and solar farms still produce electricity more cheaply than gas or other fossil fuel plants, even though costs for renewables have jumped this year. The report uses a measure called levelized cost of energy, which estimates the full price of generating power over a plant's lifetime, including construction, fuel, and operation. Onshore wind and large-scale solar again came out on top, though their costs rose 11 percent and 18 percent, mainly because federal tax credits for renewables have shrunk, tariffs have gone up, and interest rates remain high. Gas power got pricier too, up 15 percent, as a shortage of turbines has made gas plants slower and more expensive to build. None of this changes existing home rebate programs directly, but it does suggest that the broader push toward wind and solar power on the grid is likely to continue, since these sources remain the cheapest way to add new electricity generation, even without the incentives they used to get. That matters for homeowners because cheaper large-scale power generation can help keep electricity rates in check, especially as demand grows from things like data centers and air conditioning during heat waves. Elsewhere, a few developments touch home energy more directly. A new federal housing law will require stronger energy efficiency standards for manufactured homes, which are often less efficient because they are not covered by local and state building codes. And a nonprofit called Bright Saver is now selling balcony solar kits, small plug-in panel setups you can use without a large installation, starting around $300, as more states legalize them.
PJM’s old way of getting power built isn’t working. Has it found a fix?
If you live in the PJM grid region, which covers 67 million people from Virginia to Illinois, this news helps explain why your electric bill may be climbing. PJM runs regular auctions to line up enough power plants for hot summers and cold winters. Its latest auction hit the price cap of $325 per megawatt-day for the third time in a row, pushing total capacity costs to $16.4 billion, tying last December's record. Even at that price, the auction still fell short of PJM's reliability goal by over 6.8 gigawatts. Customers in Illinois, New Jersey, and Pennsylvania are already seeing bills rise more than 10 percent, and PJM's own market monitor says data centers are responsible for more than $29 billion in added capacity costs since 2024. PJM's fix is a new auction, called a reliability backstop procurement, meant to make data centers pay directly for the new power plants and batteries their huge electricity use requires, rather than spreading those costs across all customers. It would use 15-year contracts and a higher price cap, $555 per megawatt-day, to give developers enough certainty to build. This needs approval from federal regulators, with the first auction planned for September. Whether this actually protects ordinary customers is still unsettled. Advocates warn that unless states make sure data centers, not utility shareholders or general ratepayers, cover these costs, everyday customers could still end up paying for capacity built to serve data centers.
How state solar permitting mandates are picking winners and stifling innovation
Some states are pushing cities to speed up solar permit approvals by requiring automated permitting software, and a debate has opened up over how that requirement is written. In California, a law called SB 379 tells local governments they must have an online permitting system that can do what SolarAPP+ can do. SolarAPP+ is a permitting tool built by the National Renewable Energy Laboratory that lets some residential solar projects get approved automatically, without a person reviewing every detail. Critics argue that tying the law to one specific platform's capabilities favors that product over competitors, even when other systems might handle local rules better. SolarAPP+'s board includes executives from large solar installers and manufacturers, raising questions about whose interests shape the tool. When the California law was being considered, SolarAPP+ reportedly could not process an estimated 60% of residential solar permits, yet many local building departments adopted it anyway to stay in compliance with the state law. In Tracy, California, inspectors have said the platform's rigid checklists are hard to use during busy workdays. For homeowners, this mostly plays out behind the scenes at your local permitting office rather than at your kitchen table. But it can affect how fast your solar permit gets approved and how well the system accounts for your area's specific building or safety rules. As a counterexample, Bakersfield, California uses a different, more flexible permitting platform covering more than 15 types of home retrofit projects, and has seen permit processing times drop 75% with a 40% gain in staff efficiency. If you're planning a solar installation, it's worth knowing that permitting speed and ease can vary significantly depending on which system your city or county uses.
6 Records Solar & Storage Have Crushed in the First Half of 2026
Solar power and battery storage are setting records across the country this year, according to new industry data. In the first three months of 2026, solar and storage together made up 91% of all new electricity generation capacity added nationwide, the highest share ever recorded. In May, solar generated more electricity than coal for the first time in U.S. history, and it now supplies almost 13% of the country's electricity. The growth shows up most dramatically in California and Texas. On one evening in July, California's batteries discharged nearly 13 gigawatts of power, covering 36% of the state's demand during the evening hours when the grid is usually under the most strain. The next day, California's solar output hit a new high, covering 72% of afternoon demand. Texas has also broken records recently, with batteries covering a fifth of evening demand in March, renewables covering 79% of demand on another day, and solar and other renewables setting new generation highs through May. Grid operators serving other regions, including the Midwest, New England, and the mid-Atlantic, have also set new solar records in the past few months. None of this changes what any individual household needs to do. But it points to a broader shift: solar and battery storage are becoming a bigger, cheaper, and more reliable part of the electricity supply, even during hot weather when demand peaks. For homeowners weighing their own solar or battery investment, it's a sign the technology is scaling up fast, not staying niche.
PJM capacity auction results compound ‘alarm bells’: FERC Chairman Swett
If you live in the PJM grid region — the Mid-Atlantic and Midwest, covering about 67 million people — this news is about why your electric bill has been climbing and may keep climbing. PJM's latest capacity auction, which sets prices utilities pay to guarantee enough power supply, came in nearly 7 gigawatts short of the reliability target and attracted only about 500 megawatts of new power supply. Federal regulators say this points to a deeper problem with how PJM plans and approves new power projects. The Federal Energy Regulatory Commission (FERC) says PJM's process for approving changes is too slow and too closed off, which is making it harder to get new power plants and grid upgrades built when they're needed. FERC is holding a hearing on July 23 to look for fixes, with the goal of a clearer path forward soon after. None of this changes anything about home energy programs directly, but tight power supply and rising capacity costs are part of why utility rates in this region have been under pressure. The meeting also touched on data centers, which are consuming more electricity and adding strain to grids like PJM's. FERC set year-end deadlines for new reliability rules covering these large computing loads. For homeowners, the practical takeaway is simply that grid capacity and pricing in the PJM region remain unsettled, which is worth keeping in mind if you're weighing the value of home upgrades that reduce your own electricity use.
June legislative session roundup
Three states with part-time legislatures — New Hampshire, Delaware, and Rhode Island — wrapped up their sessions in June, and a few building-related bills didn't make it through. In New Hampshire, a bill that would have updated the state's building energy code from the 2018 version to the newer 2024 version died in committee, so the older, less efficient code stays in place for now. Delaware's legislature spent the session on budget matters and didn't take up any building-related measures. Rhode Island saw the most activity, though little of it succeeded. The governor vetoed a bill that would have required owners of large residential and commercial buildings (over 25,000 square feet) to report their annual energy use and emissions — a step that could have affected larger apartment buildings, though not typical single-family homes. Separate bills that would have lowered the certification threshold for public building renovations and required new public buildings to meet green building standards were shelved for further study. A bill on indoor air quality inspections in public schools passed the Senate but stalled in the House. And an attempt to repeal the state's 2021 climate law, which sets targets for cutting emissions statewide, failed to advance. None of this changes anything for homeowners right now, but it's worth keeping an eye on if you live in Rhode Island — some of these ideas, like energy reporting rules and stronger building codes, tend to resurface in future sessions and can eventually shape rebate programs or renovation requirements.
Don’t Hide the Thermometer: Data Leads to Better Decisions
Federal climate data released this year shows the first half of 2026 was the third-warmest start to any year on record. Every month from January through June ranked among the five warmest ever measured for that month, and June brought the hottest ocean temperatures ever recorded for that month globally. Scientists say it's very likely 2026 will end up among the five warmest years on record. What's changed is how visible this information is. Under the previous administration, NOAA's monthly climate reports were front-page news on the agency's website for days at a time. Now the data is published quietly by a sub-agency, with no press push, making it harder for ordinary people to find. This is part of a broader pattern: NOAA retired its disaster-cost database (which tracked the toll of hurricanes, floods, and wildfires) with no updates past 2024, the federal site hosting the National Climate Assessment reports went offline last year, and the EPA has proposed ending the program that requires large facilities to report their greenhouse gas emissions. None of this changes what's happening at your own house. Rising heat and worsening storms still drive higher cooling bills, more strain on aging HVAC systems, and greater risk from extreme weather where you live. The information is simply harder to find than it used to be, which is worth knowing if you're trying to track how a warming climate might affect your own energy costs and home upgrades over time.
Solving the HOA funding trap with a 300 kW Southern California solar and roof bundle
A commercial homeowners association in Foothill Ranch, California found a way around a common problem with solar: putting new panels on a roof that's near the end of its life. Normally an old roof means you'd have to remove the solar system, replace the roof, and reinstall the panels partway through a 25-year contract, an expensive hassle. The Foothill Medical Center Association avoided this by rolling a full roof replacement into its solar financing. The HOA signed a power purchase agreement, or PPA, meaning a developer pays for and owns the solar system while the HOA buys the electricity it produces, with no upfront cost. The financing was structured to cover both a 300 kW solar system (spread across rooftops and new parking carports) and a complete roof reconditioning, so the association didn't need to charge members special fees or dip into its savings. Crews did the roof and solar work in one continuous construction sequence instead of two separate phases, which kept the timeline tight and avoided disruption. The finished system is expected to generate about 506,000 kWh of electricity a year, offsetting roughly 359 metric tons of carbon dioxide annually. It's designed to work with Southern California Edison's time-of-use rate plan, drawing on solar power when electricity is most expensive. For homeowners in an HOA with an aging roof, this project shows that solar financing can sometimes be structured to cover roof repairs too, avoiding the need for separate, costly assessments.
Podcast Episode 746: Steam Humidifiers, Hydraulic Drivers, and Changes in Construction
A recent podcast touched on a few things worth knowing if you're thinking about home upgrades. One listener in Reno described a problem worth watching for: after sealing up his crawlspace (a common energy-efficiency fix that stops outside air, moisture, and gas from leaking into the house from below), his indoor humidity dropped sharply in winter, from 60 percent down to 23 percent. Steam humidifiers, a common fix for dry indoor air, turned out to use a lot of electricity. He switched to a standalone evaporative humidifier that uses a fan and rotating paddles to add moisture to the air, drawing just 2.8 watts on medium speed, and it raised his humidity to a more comfortable 33 percent. The lesson for anyone doing a crawlspace or basement seal-up: it can change your indoor humidity more than you'd expect, and the standard fix (steam) isn't the cheapest one to run. The episode also covered a new type of impact driver that uses hydraulic or oil pressure instead of a hammering mechanism, making it quieter than standard impact drivers. Fine Homebuilding plans a full comparison test of these tools in an upcoming print issue. This is a tool-shop detail more than a homeowner decision, but it may show up in future coverage of contractor equipment. Finally, a listener asked how home-building practices have changed over the ten years the podcast has run, prompting the hosts to reflect on shifts in materials, wall assemblies, and techniques since 2016. No specifics on what's changed were given in this episode.
The Grid Needs Storage, Not Every Storage Idea
A new long-range analysis of grid storage looks out to the year 2100 and concludes the power grid will need a lot of batteries and pumped hydro (a system that stores energy by pumping water uphill, then releasing it through turbines later), but far less exotic storage than some forecasts assume. Battery costs keep falling fast, and batteries are increasingly being built for longer stretches of storage, not just the two-to-four-hour systems that used to be standard. Britain has approved battery projects designed to store power for eight to eighteen hours, and China's battery fleet has grown enormously, though most of those batteries still store only around two hours' worth of power. The analysis argues that grids will need less dedicated battery and pumped-hydro storage than once thought because other tools can do part of the job more cheaply. These include long-distance power lines that move electricity between regions with different weather, shifting flexible demand (like EV charging or water heating) to times when power is cheap and plentiful, and storing heat itself — in hot water tanks, underground boreholes, or district heating systems — rather than converting it back and forth from electricity. For homeowners with heat pumps, this last point matters: heat storage systems can help smooth out the cost and strain of winter power demand, since heat pumps draw more electricity on the coldest evenings. For newer storage ideas like compressed air, liquid air, or iron-air batteries, the analysis says they still need to prove themselves with real, working projects before they deserve a bigger share of future grid plans.
Dominion acquisition by NextEra could cost SC customers, groups warn
Dominion Energy South Carolina and Florida-based NextEra Energy have asked the South Carolina Public Service Commission to approve NextEra's purchase of Dominion. At $67 billion, it would be the largest utility acquisition in U.S. history and would create the country's biggest monopoly utility. Both companies say the deal serves the public interest, but consumer and environmental groups disagree. Groups including the Southern Environmental Law Center, Coastal Conservation League, Vote Solar, and the Southern Alliance for Clean Energy warn the acquisition is tied to plans to profit from growing AI data center demand. They say Dominion is already planning to expand gas-fired power plants, and a larger, NextEra-controlled utility could push that further, adding pipelines and gas infrastructure that customers would ultimately pay for through their bills. This comes as several South Carolina counties have already paused data center proposals over similar concerns, and as Dominion customers face a recent rate increase. Critics also point out that NextEra has sought some of the largest rate increases in U.S. history in Florida, and they argue South Carolina regulators should require clear proof the deal will keep rates affordable and protect service quality before approving it, rather than accepting it on the promise of future benefits. For homeowners served by Dominion Energy in South Carolina, this matters because decisions made in this regulatory review could affect future electric rates and how much new gas infrastructure gets built and paid for through customer bills. The state commission has not yet ruled on the application.
Brilliant AI Solution to High Solar Soft Costs & Overpricing in the United States
Rooftop solar in the US tends to cost a lot more than in other countries, largely because of "soft costs" — things like sales commissions and marketing that get added on top of the equipment price. One estimate puts the total overpayment by US homeowners in 2025 at around $2 billion compared to fair market prices, a premium one industry figure calls a "sales-rep tax." A new company, AgentSolar AI, is trying to fix that by acting as an automated stand-in for the homeowner during the buying process. Instead of just giving a rough price estimate, its AI reviews a full solar proposal — even a 40-page contract — and checks the pricing and terms against market data. It also researches the installer's history and reviews to help verify the company is reputable. If you decide to move forward, the system doesn't just hand you the deal — it runs a negotiation process on your behalf, drafting counteroffers and sending emails to try to get better terms. A human reviewer also checks over the communications before anything goes to the homeowner. The idea is to give homeowners the kind of pricing knowledge and negotiating leverage that installers and their sales reps usually have, and to keep offers from reaching you until the system judges them fair. It's a new approach, and whether it actually pushes overall solar prices down remains to be seen. Permitting delays, a separate cost driver in home solar, are also being worked on elsewhere in the industry.
Is A Double-Shock What Will Really Change Auto Purchasing & Oil Use Again?
Gas prices have been swinging with world events. A gallon averaged $4.56 on May 21, after conflict in the Middle East pushed oil prices up, following an earlier spike tied to Russia's invasion of Ukraine. Prices have since eased, with the national average now at $3.943 a gallon. But tensions remain, including U.S. military action against Iran and Iran's move to close the Strait of Hormuz, a key shipping route for oil. The question being raised is whether repeated price shocks like these could push more drivers toward electric vehicles, the way the oil crises of the 1970s led to a lasting drop in gasoline use. There's no new program, rebate, or deadline here, just a look at whether history might repeat itself. In the 1970s, two big oil shocks caused a sharp, long-term decline in oil consumption as people changed how they drove and what they drove. Some now wonder if a similar "double shock" from Ukraine and the Middle East could speed up the shift away from gas-powered cars in a lasting way, rather than just causing temporary pain at the pump. For homeowners, the direct takeaway is limited: this is about gas prices and vehicle trends, not home energy upgrades or rebates. But if you're weighing a switch to an electric vehicle, and possibly charging it with home solar, this is a reminder that gas price swings tied to global conflicts remain a real, if unpredictable, part of that math.
Bridging the workforce gap in commercial solar through integrated training models
The solar industry is short on skilled workers, especially technicians who can handle the wiring, diagnostics, and long-term upkeep of larger commercial systems. Nearly 90% of solar employers said they had trouble filling jobs last year, and maintenance roles have been the hardest to staff as more systems come online and need ongoing service. One example: Mountain Empire Community College in Virginia partnered with a solar developer and an electrical contractor to build a large solar system on campus while training students on the actual job site. The system, over 1,600 panels, was built through a power purchase agreement, meaning the college paid nothing upfront and instead buys the power it generates. It's expected to cover about a third of the campus's energy use and save an estimated $2.4 million over its lifetime. Students in the program earned wages while training and moved directly into jobs afterward, rather than searching for work after finishing a course. This is mostly industry news about training programs and job pipelines, not a homeowner program. But the power purchase agreement financing used here is worth knowing about generally: it lets a building owner get solar power without paying for the system itself, in exchange for buying the electricity it produces. Similar arrangements sometimes exist for homeowners, depending on where you live, so it can be worth asking whether that option is available in your state.
PureSky refinances community solar, battery storage portfolio
PureSky Energy, a company that builds and runs community solar and battery storage projects, has refinanced its operating portfolio in a $183.7 million deal. Community solar lets people subscribe to a shared solar project and get credit on their electric bill, even if they can't put panels on their own roof. This news is about the company's financing, not a new program you can sign up for directly, but it points to where community solar is growing. The refinanced projects cover 43 solar and storage sites in Massachusetts, New York and Minnesota, adding up to about 211 megawatts of solar and 58 megawatt-hours of battery storage. If you live in one of those states, this is the kind of project that might show up as a community solar subscription option in your area, since PureSky said the deal secures financing for the portfolio for the next decade, meaning these projects are set to keep operating. The company also expanded its corporate credit line by $62 million, arranged by the bank Nomura, with investors including PGIM, AB CarVal and Denham Capital. PureSky said the money gives it more flexibility to keep building new solar and storage projects. The company has been active in the US since 2016 and now has roughly 300 megawatts of capacity either running or under construction across 63 sites. For homeowners, the takeaway is less about immediate savings and more a sign that community solar developers are lining up financing to expand, which could mean more subscription options down the road, especially in the states where PureSky already operates.
A New Commercial VRF Platform From GE Appliances
GE Appliances has launched a new commercial VRF (variable refrigerant flow) heat pump lineup called the GE R-32 VRF platform. VRF systems use a single outdoor unit to send refrigerant to multiple indoor units, letting different rooms or zones heat and cool independently. This new line is aimed at light commercial buildings, not homes, and is meant to help engineers and contractors design and install these systems more easily on office, retail, and similar projects. The lineup includes two main systems. The MRV-7 offers single units ranging from 6 to 20 tons of capacity, with the option to combine units for up to 36 tons total. The MRV-7S is a smaller-capacity option, covering 3 to 5 tons, including single-phase power setups suited to smaller commercial buildings. Both use R-32 refrigerant and come with features like corrosion protection, quiet operation, wide operating temperature ranges, and compatibility with various indoor unit types such as ducted units, wall-mounted units, and cassettes. For homeowners, this news doesn't apply directly to your house. VRF systems at this scale are built for commercial buildings, and the announcement is aimed at the contractors and engineers who spec out those projects. If you're considering a heat pump for your own home, this isn't the product line to look at, but it does show that GE Appliances is continuing to expand its heat pump offerings more broadly across both commercial and residential markets.
The off-grid data center fantasy
A recent industry discussion looked at whether AI data centers will actually go "off-grid" — building their own private power plants instead of connecting to the regular electric grid. One research firm, SemiAnalysis, predicted more than 40 gigawatts of this private, "behind the meter" power (mostly gas turbines, engines, and fuel cells) at U.S. data centers by 2028. But two energy experts on a podcast pushed back hard, arguing that timeline is unrealistic given how long it takes to build power equipment, plus shortages of transformers, switchgear, and skilled electrical workers. The bigger disagreement is over what actually fills the gap between data center demand and available grid power in the next few years. One side argues batteries and "load flexibility" — using existing grid capacity more efficiently rather than building all-new power plants — is the more realistic near-term answer. They point out the U.S. already has plenty of battery manufacturing capacity and tax credits supporting it, while gas turbines face years-long waits and rising costs. The other viewpoint stresses that fully self-sufficient data centers create real risks: they can strain supply chains for equipment everyone needs, without necessarily adding cheaper power back to the shared grid that would benefit other electricity customers. None of this points to something a homeowner needs to act on. It mainly signals how the huge growth in AI data centers could affect regional power costs and grid reliability in the coming years, depending on whether utilities lean on batteries, gas generators, or flexible demand programs to meet the new load.
APsystems introduces plug-in microinverter for U.S. balcony and DIY solar markets
A company called APsystems has released a small solar device aimed at people who want to try solar without a full rooftop installation. The EZ1-LV is a microinverter, a device that converts power from solar panels into the kind your home can use. It's built for small setups like balconies, gardens, garages, or carports, not standard rooftop arrays. What makes it notable is how it connects: instead of hardwired electrical work, it can plug into a regular household wall outlet using an optional 120-volt extension cable. That could make it appealing to renters or homeowners who want a simple, low-commitment way to generate some of their own power. The unit connects to two solar panels at once, works with common panel sizes, and is built to handle outdoor conditions, with a temperature range from -40°F to 149°F. You can monitor how much power it's producing through a smartphone app, either nearby via Bluetooth or remotely over Wi-Fi, and up to four units can be tracked at once. On the safety side, the device meets U.S. and Canadian electrical standards, including rules for arc-fault protection and rapid shutdown that apply across multiple versions of the National Electrical Code. It comes with a 12-year warranty. For homeowners curious about small-scale solar, this points to a broader trend: manufacturers are making plug-in, DIY-friendly systems that don't require a full rooftop installation or extensive wiring, lowering the cost and effort of getting started with solar power at home.
Wildfire smoke threatens the World Cup final. FIFA still doesn’t have a plan.
Wildfire smoke drifting down from Canada has pushed air quality to hazardous levels across more than a dozen states this week, including New York, where the World Cup final between Argentina and Spain is set for Sunday. New York issued an air quality alert as levels climbed into the "unhealthy" and "very unhealthy" range, telling residents to avoid time outdoors. Near the stadium in New Jersey, air quality was still unhealthy as of Friday morning, though forecasts suggest it could improve to "moderate" by kickoff. Smoke exposure can cause a burning throat, coughing, and headaches, and poses more risk for children, older people, and those with asthma or other respiratory conditions. FIFA, soccer's governing body, has no stated plan for handling wildfire smoke, unlike its detailed rules for extreme heat, such as mandatory water breaks. Other leagues have acted this week: the National Women's Soccer League added extra hydration breaks during a smoke-affected game in New York, Major League Baseball rescheduled a game in Philadelphia, and Major League Soccer canceled a match in Chicago. FIFA says it coordinates on "climate-related risks" with host cities and agencies, but has no public policy tied to specific air quality levels, and the open-air stadium hosting the final can't be sealed off if smoke returns. This isn't about your home directly, but it's a reminder that wildfire smoke is increasingly reaching far beyond the regions actually burning, affecting daily life and outdoor plans well outside the West.
Whoa, Honda to Stop Selling Prologue EV … What the Heck?
Honda is discontinuing the Prologue, its electric SUV, in the United States after the 2026 model year. That comes as a surprise, since the Prologue has been one of the best-selling EVs in the country, ranking 6th in 2025 and 8th last quarter, with sales recently picking back up after a dip tied to the loss of the federal EV tax credit last year. The Prologue was always something of a stopgap for Honda. It's built on General Motors' Ultium electric platform, which Honda used to get an EV to market quickly while it worked on its own electric vehicle technology. So it was never a from-scratch Honda design, and its exit doesn't necessarily signal a retreat from EVs for the company overall. For a homeowner, this doesn't change anything about home energy upgrades, rebates, or electrification programs. If you were considering a Prologue, it's worth noting you'll only be able to get the 2026 model before it's gone, and after that Honda's electric SUV lineup in the US will look different. If you're weighing an EV alongside home charging setup or a rebate for a home charger, it's a reminder to check current model availability before assuming what you saw last year is still on the lot.
AI data center growth could force US utilities to rethink generation plans, BofA says
Bank of America analysts project the US will need more than 230 gigawatts of new power generation over the next five years, but utilities are on track to add only about 93 gigawatts, leaving a gap of over 100 gigawatts. The main driver is data centers built to run AI systems, which could add roughly 125 gigawatts of new electricity demand through 2030. That would push overall power demand up faster than it has grown in years. Because large gas turbines are largely sold out through 2030, the analysts expect more data centers to build their own on-site gas generation rather than wait on the grid, and utilities to keep aging coal plants running longer than planned in states including Maryland, Wisconsin, Indiana, Utah, Kansas, Nebraska and Mississippi. Battery storage and transmission upgrades are also part of the response, though new transmission lines can take well over a decade to build. For homeowners, this is a sign that electricity demand and the strain on local grids may keep climbing in the years ahead, driven largely by data centers rather than household use. Research cited in the report suggests that even when power prices rise, people don't cut back much on electricity use. There's no specific rule or program here tied to home upgrades, but it's a reminder that the reliability and cost of home energy may increasingly depend on how utilities in your area handle this new, data-center-driven demand.
Nuclear energy could be in for a big decade
Nuclear power looks set for its biggest growth spurt in decades. After years of standing still following the 2011 Fukushima disaster, global nuclear capacity is expected to jump 44 percent by 2036, according to a new forecast from BloombergNEF, rising from 372 gigawatts last year to 535 gigawatts. Right now 76 reactors are under construction worldwide, nearly all of them large conventional plants rather than the smaller "small modular reactors" that have gotten a lot of buzz lately. The renewed interest comes from countries trying to cut carbon emissions while also meeting fast-rising electricity demand. Nuclear plants provide steady, carbon-free power, and the recent Iran war, which unsettled oil and gas markets, has pushed some countries, including Japan, to take a fresh look at nuclear energy. China is driving most of the current buildout, with nearly half the reactors under construction globally. It could pass the U.S. in total nuclear capacity by 2030. In the U.S., officials are talking up plans to expand nuclear power, though actual construction remains far behind China's pace. Two smaller advanced reactors are being built, and a nuclear plant in Michigan may restart later this year after missing an earlier 2025 target. Whether this nuclear rebound really delivers depends on cost and timing. U.S. nuclear projects have a history of running over budget and behind schedule, and the industry's growth may hinge on proving it can build reactors faster and cheaper than it has in the past.
Inside Amazon’s approach to data center sustainability: A conversation with Brandon Oyer
Amazon has been talking publicly about how it powers and cools its data centers, and some of it touches on things happening in local grids and water systems. The company says it pays the full cost of electricity and grid upgrades for its data centers rather than passing those costs to other customers' bills. It points to two examples: in Indiana, utility Indiana Michigan Power cut base rates for customers, citing added revenue from large customers like Amazon, and in Mississippi, Entergy plans to invest an extra $300 million in grid improvements at no added cost to customers, which it expects will cut power outages in half over five years. Amazon is also investing in nuclear power, including small modular reactors (SMRs) — smaller nuclear plants built in stages rather than one huge unit — as a way to add carbon-free electricity to the grid, through a $500 million investment in a company called X-energy. On water, Amazon says it has cut its data centers' water use effectiveness by 52% since 2021 and is aiming to be "water positive" by 2030, meaning it would return more water to communities than it uses. It's shifting toward recycled water (treated sewage) instead of drinking water for cooling, and funding water projects in places like Mississippi (helping farmers use less irrigation water), Mexico, and Oregon, where a $235 million investment is meant to reduce reliance on groundwater. None of this requires anything from homeowners directly, but it may show up as changes in local utility rates or water infrastructure in areas near new data centers.
