Watsco Sees Stabilizing Market as Q2 Sales Increase
Watsco, one of the largest distributors of home heating and cooling equipment in the country, reported that its business is settling into a more normal pattern after last year's industry-wide shift to new refrigerants. That shift, tied to environmental rules, pushed manufacturers to raise prices in 2025 to cover higher costs. This year those price jumps have leveled off, which the company says better reflects what's actually happening in the market. For homeowners, this is mostly a signal about pricing trends rather than a program you can use directly. Watsco reported that residential equipment sales rose 5% for the quarter, with both unit sales and average prices up slightly, suggesting demand for new furnaces, air conditioners, and heat pumps is holding steady without the price spikes seen last year during the refrigerant changeover. The company also highlighted its digital tools that contractors use to quote and sell HVAC jobs to homeowners. One of these, called OnCallAir, was used to present quotes to about 342,000 households over the past year, with $1.9 billion in equipment sold through the platform. This points to more contractors using online tools for quotes and scheduling, which may show up as instant estimates or digital scheduling options when you get bids for a new system. Watsco also grew its distribution network by acquiring Jackson Supply Co., adding 25 locations across the South and Southwest, giving the company more than 700 locations across North America.
EvenAir 2.0 Balances Temperatures Throughout the Home
Field Controls has released an update to its EvenAir system, a device meant to even out temperature swings between rooms without installing a full zoning system or a second HVAC unit. Called EvenAir 2.0, it works alongside your home's existing thermostat and a single heating and cooling system, using sensors and adjustable dampers (panels inside the ductwork that control airflow) to manage up to three areas of the house separately. The updated version checks temperatures every two minutes while heating, cooling, or running the fan, comparing readings from different parts of the house against the main thermostat and adjusting the dampers accordingly. The idea is to stop upstairs rooms from overheating in summer or downstairs rooms from staying cold in winter, and to smooth out rooms that get more sun or outside exposure than the rest of the house. The company markets EvenAir 2.0 as a lower-cost alternative to installing separate zoning controls or a second HVAC system, aimed particularly at split-level and two-story homes, or any house with a room or two that never seems to match the rest. If you've dealt with an upstairs that runs hot in summer or a downstairs that stays chilly in winter, this is the kind of add-on system worth asking about the next time you're looking at HVAC upgrades, since it works with equipment you likely already have rather than requiring a full system replacement.
UNIGRID, Syntropic Power are planning US sodium-ion battery manufacturing
A new type of home battery is moving toward production. Two companies, UNIGRID and Syntropic Power, are teaming up to build sodium-ion batteries in the United States, with plans to manufacture the cells domestically by the end of 2027. Sodium-ion batteries use a different chemistry than the lithium-ion batteries common in home storage today, and the companies say this version, called sodium chromium oxide (NCO), performed well in independent lab testing at the Rochester Institute of Technology. The tests found high efficiency, strong performance over more than 1,000 charge cycles, and stable behavior even under extreme conditions, without needing mechanical cooling systems. For homeowners, the near-term product to watch is called Tenet, a wall-mounted battery meant for houses, small businesses, and "virtual power plant" programs that let utilities tap into home batteries during peak demand. A larger version, GridSpan, is aimed at big installations like grid-scale storage rather than individual homes. The companies plan to deploy 1 gigawatt-hour of this battery technology in 2027, starting with these two products. This is still an early-stage development. No manufacturing locations have been announced, and the batteries have not yet reached the market for home installation. But if it moves forward as planned, it could give homeowners another battery option beyond the lithium-ion systems currently sold for solar and backup power, potentially with different safety and durability characteristics.
The Fast Lane: 3 Ways Geothermal Companies Can Get More Heat
Researchers at a national energy lab have developed new tools meant to help geothermal companies drill deeper and hotter wells, which could eventually mean more geothermal power on the grid. Geothermal energy comes from heat stored underground, and the deeper companies can drill, the more power they can generate from the same equipment. The new inventions include a generator that withstands temperatures near 500 degrees Fahrenheit and sits near the drill bit itself, avoiding the wires that break down in extreme heat, plus heat-tolerant sensors that let drillers see underground conditions even where standard electronics would fail. A separate software tool, called GEOPHIRES, helps developers estimate a project's costs and likely profits before they start digging, using details like drilling depth, construction timeline, and local electricity prices. None of this is something a homeowner needs to act on directly. It is research aimed at geothermal developers and drilling companies, not at homeowners installing geothermal heat pumps or ground-source systems on their own property. The technology is about making large-scale geothermal power plants cheaper and more efficient to build, which could, over time, add more geothermal electricity to the grid. It has no immediate bearing on home energy upgrades, rebates, or equipment choices, but it is a sign that the broader geothermal industry is working to bring costs down and reach hotter, deeper resources than before.
Transmission logjams and AI load growth push data centers toward on-site solar, storage, and VPPs
The country's electricity demand is climbing fast, driven by AI data centers, manufacturing, and the shift to electric appliances and vehicles. But new power lines take years to build, sometimes up to 15 years, and the queue of projects waiting to connect to the grid has ballooned past 2,200 gigawatts, far more than the grid can currently carry. Utilities plan to spend $1.1 trillion on grid upgrades through 2029, but even faster regional projects take six to seven years. Because of this lag, data center developers are increasingly building their own power on-site, roughly 56 gigawatts' worth of solar and battery projects nationwide, led by Texas, New Mexico, Pennsylvania, and Utah. Some grid operators are now fast-tracking connections for facilities that bring their own generation. This shift is creating new interest in tapping home energy equipment to help balance the grid. Companies including Sunrun, Tesla, and Renew Home have announced plans for a 16-gigawatt "virtual power plant," which pools home batteries and smart devices across many houses to add power to the grid when needed. Google and Voltus have a similar deal to pull 100 megawatts from flexible home and business equipment. One industry study estimates that smart thermostats, batteries, and other flexible devices in homes could unlock up to 200 gigawatts of capacity nationwide. For homeowners, this means a battery, smart thermostat, or solar-and-storage system may increasingly be worth something beyond backup power or bill savings: utilities and tech companies are actively looking to pay for access to that flexibility to help meet rising demand.
SolarEdge swings back to operating profit in Q2 as margins hit 27.5%
SolarEdge, the company behind much of the equipment that manages solar panels and batteries in home systems, reported a rebound in its latest quarter. Revenue came in at $346.2 million, up nearly 20% from a year earlier, helped by strong demand in Europe and growth in commercial solar installations in the U.S. That growth offset a continued slowdown in U.S. home solar demand. The company also returned to a profit on an adjusted basis for the first time in three years, a sign that the broader solar equipment market may be stabilizing after a rough stretch. For homeowners, the more relevant news may be SolarEdge's plans for its home energy products. The company is rolling out a new home energy platform called Nexis, starting in Germany, with a goal of it making up most of its home solar sales by early 2027. That suggests homeowners considering solar or battery systems in the coming year or two may see this newer equipment offered by installers, particularly in European markets first, with wider availability expected to follow. The company is also working with chipmaker Infineon on technology aimed at powering large AI data centers, a separate business line that has nothing to do with home systems but reflects where SolarEdge is investing beyond residential solar. For its next quarter, the company expects revenue between $310 million and $340 million, roughly in line with current levels.
Facing an estimated 474 GW of interconnection requests, Texas hits pause on data centers
Texas Gov. Greg Abbott has ordered an audit of every data center waiting to connect to the state's power grid, run by the Electric Reliability Council of Texas (ERCOT). Requests for new power hookups now total about 474 gigawatts — more than five times the state's record peak electricity demand — and Abbott says about 90 percent of that is data centers. In response, ERCOT has delayed the first round of reviews under its new large-load connection process and plans to ask state regulators for more time. The audit will look at whether data centers plan to generate their own power or lean on the shared grid, how much water they'll use and whether they bring their own supply instead of drawing on water communities need, and whether they're paying their own way or relying on state and local tax breaks and other public money. Abbott says any project that doesn't comply should be denied. The data center industry's trade group says it welcomes the review as a way to separate serious, committed projects from speculative ones. For homeowners, this doesn't change your rates or service today, but it's part of a broader reckoning over how much new demand from data centers the grid can actually absorb — and who ends up paying for the power plants, transmission lines and water needed to support them. Texas follows New York, which paused new data center approvals in July while it writes new rules.
Base Power begins manufacturing 39.2-kWh residential battery in Texas
Base Power, a company that runs home batteries as part of a shared "virtual power plant" network, has raised $1 billion and started making its own battery in Austin, Texas. The new product, called Base Core, is a 39.2-kWh home battery using lithium-iron phosphate (LFP) chemistry, a type known for being stable and long-lasting. It's rated for 12 years of use and carries two safety certifications, UL 1973 and UL 9540, which cover battery performance and installation safety. The company says Base Core installs in under an hour, switches over automatically during a power outage, and is built to handle extreme weather. Base Power is already making thousands of these units a month and plans to sell them first in Texas and Illinois, where it already runs a fleet of home batteries totaling more than 500 megawatt-hours under contracts that let it draw on customers' stored power to help balance the electric grid. For homeowners in those two states, this means a new battery option is entering the market, with a claimed fast install and extended backup power during outages. Base Power has raised over $2.5 billion total and plans to use the new funding to expand Core to more homes and eventually into other states, though no timeline or pricing for that broader rollout is included here. If you live outside Texas or Illinois, this battery isn't available to you yet, but it's a sign more homeowners may have access to it down the road.
Demystifying Old-Growth Lumber
"Old-growth lumber" is a term old-house owners and craftspeople often bring up, usually to argue that wood used to be better. It turns out old growth isn't a species or grade of wood — it describes a forest condition. The U.S. Forest Service defines old-growth forests as ones with old trees and structural features that developed over long stretches of time without major disturbance, like fire or logging. Trees in these forests are generally 100 to 150 years old, shaped by competition for light and space as they grew. Most of the old-growth lumber people prize today was cut down and milled in the 1800s and early 1900s, starting in the eastern U.S. and moving west as forests there were exhausted. By around 1920, more than two-thirds of American forests had been cut at least once. What grew back afterward is called second-growth, third-growth, and so on — and that's mostly what today's lumber comes from. The upshot for anyone with an old house: the reason old-growth wood is scarce isn't that we've lost the ability to grow it, but that modern forestry doesn't leave trees standing undisturbed for a century or more before harvesting. If you're weighing repairs versus replacement on old timber or trim in your home, it helps to know that what makes that wood distinctive is really its age and growing conditions, not some lost manufacturing technique.
Wildfire season is changing. Spokane is showing how.
Wildfires this week destroyed more than 700 buildings in the Spokane Valley, part of what's become Washington's most destructive fire season on record, with over half a million acres burned and at least 65,000 people ordered to evacuate statewide. Oregon has already broken its annual record for acreage burned, with nearly 2 million acres scorched. A dry winter, low snowpack, and early heat left the region primed to burn. Officials point to a specific vulnerability that applies well beyond Spokane: neighborhoods built where houses meet forests and brush, known as the wildland-urban interface. This kind of development is the fastest-growing type of housing in the country, and research shows homes in these areas are more likely to burn when wildfires spread nearby. In Spokane, steep terrain, dense vegetation, and neighborhoods with only one or two roads in and out made evacuation slow and dangerous. Some fire-prone states, including California, now require homeowners to maintain a cleared buffer around their house, called defensible space, meaning trees and shrubs are kept back from the structure. Officials say this buffer can significantly cut the odds that a wildfire ignites a home. If you live near wooded or brushy land, especially with limited road access, it's worth knowing whether your state or county has similar defensible-space rules, and whether your property's landscaping and evacuation routes currently meet them.
The 14 Manufacturers Participating in California’s New MyFirstEV Program
California has launched MyFirstEV, a $135.5 million incentive program for people buying their first electric vehicle. The money works through car dealers rather than a rebate you apply for later: at the point of sale, first-time EV buyers or lessees get $3,500 off a new vehicle ($1,750 from the state, matched by $1,750 from the automaker) or $1,750 off a used one ($875 from each). To keep the program focused on affordable cars, new vehicles must have a sticker price under $50,000, and used ones must sell for under $25,000 (California-based manufacturers are exempt from the cap). Fourteen automakers have signed on, but they're not all ready yet. Chevrolet, Ford, Hyundai, Kia, Lucid, and Tesla are set to start offering the incentive in August 2026. Honda, Lexus, Subaru, and Toyota follow in September, Mitsubishi in November, and Nissan, Rivian, and Volvo are listed as "coming soon" without a firm date. New vehicles must be model year 2026 or newer, and used vehicles have to be at least two model years older than the sale date. If you're a California resident shopping for your first EV, timing matters here: the state warns that any vehicle ordered or purchased before your dealer's manufacturer has actually activated the incentive won't qualify for it. So it's worth checking with the dealer directly on whether the discount is live for that specific brand before signing anything.
Vapor Barriers and Alaska
A homeowner in Anchorage, Alaska, is re-siding a 1983 house and asked for advice on a wall moisture question. The house has 2x6 walls with plastic vapor barrier on both the inside and outside of the studs, fiberglass insulation, plywood sheathing, and a thick coat of polyurethane over the original cedar siding. The contractor plans to wrap the whole house, including a new addition, in Tyvek (a water-resistant barrier, or WRB, that keeps out rain but lets some vapor pass) before installing new LP SmartSide siding over the old cedar. The homeowner is worried that adding a second vapor-blocking layer outside an already vapor-blocked wall could trap moisture inside the wall cavity, even though no mold or rot turned up when they opened up sections of the wall during the addition work. This is a specific building-science question posted to a contractor forum, not a program announcement or new product. No answer had been posted yet at the time of writing, so there is no recommended fix to report. For homeowners in cold climates with older walls that already have a vapor barrier, the takeaway is a general one: adding new exterior layers over existing siding during a re-siding job can change how a wall dries out, and it is worth understanding what materials are already in the wall before wrapping it in something new. If you are planning a similar re-siding project on an older home, especially one with a plastic vapor barrier already built in, it is worth having someone look closely at the full wall assembly before adding another layer outside.
LA City Council Votes to Allow Billion Dollar Scattergood Gas Plant Retrofit to Move Forward
The Los Angeles City Council voted 10-3 to reject an appeal from environmental groups and let the Department of Water and Power move forward with a $1 billion retrofit of the Scattergood gas plant. The plan would let Scattergood burn a mix of natural gas and hydrogen. LADWP first announced the retrofit in 2022 as part of its path to 100% renewable energy by 2035, but critics say the city has no real source of hydrogen to burn, especially after a related hydrogen pipeline project, Angeles Link, was recently canceled. Council members Yaroslavsky, Raman, and Hernandez voted to back the appeal; Councilmember Soto-Martinez recused himself over hydrogen-related investments. Opponents, including the Sierra Club, Food & Water Watch, Los Angeles Waterkeeper, and other groups, argue the plant will likely just run on gas for decades, since green hydrogen isn't available and is costly and water-intensive to produce. They say LADWP is falling behind on its own solar and storage goals and that ratepayers could be paying off this gas plant for 50 years. The plant sits near Inglewood, Hawthorne, and Lennox, communities that already deal with pollution from fossil fuel infrastructure. For homeowners, this doesn't change any rebate or program you can apply for. It's a reminder that Los Angeles's broader shift to clean electricity is moving slower than planned, and that ratepayers may see costs tied to this gas plant investment show up in utility bills over time.
USGBC appoints David Purcell as chief marketing officer
The U.S. Green Building Council, the group behind the LEED green building rating system, has named David Purcell as its new chief marketing officer. Purcell has more than 30 years of marketing experience at companies like American Express, Visa, and Charles Schwab, and he will now lead USGBC's marketing and communications work from its Washington, D.C. headquarters. This is a corporate leadership change rather than a new program or rebate, so it doesn't come with any new savings, deadlines, or rules for homeowners. USGBC's stated goal is to widen the reach of LEED, the certification system used to rate how efficiently buildings are designed and operated, along with a zero-waste certification called TRUE. The organization is also promoting its LEED v5 rating system, an updated version meant to speed up adoption of greener building practices. If you've come across LEED certification while researching a home renovation or a new-construction property, this is the organization that sets those standards, and this appointment signals it plans to push harder on marketing and expanding who uses its programs. There's no direct action for homeowners here, but it's a sign that green building standards and certifications may get more visibility going forward. USGBC also mentioned its Greenbuild conference, happening October 20-23 in New York City, which is aimed at building professionals rather than individual homeowners.
EVgo-branded Tesla Superchargers are coming
This is news about electric vehicle charging, not home energy upgrades, but here's what happened: EVgo, a public fast-charging company, is installing Tesla's newest charging hardware at its own stations, branded as "EVgo Superchargers." Construction starts this fall, with the first sites opening in the second half of 2026. Each location could have up to 20 charging stalls near stores and restaurants. The chargers will run on Tesla's V4 hardware, capable of delivering up to 500 kilowatts, and EVgo says drivers could add up to 200 miles of range in 15 minutes at a compatible vehicle. They'll include Tesla's Magic Dock, a plug adapter built into the charger that lets Teslas and other electric vehicles — whether they use Tesla's NACS plug or the older CCS plug — charge without needing to bring an adapter. The stations will also show up in Tesla's in-car navigation and trip planner, so Tesla drivers get routed to them automatically. For homeowners, this doesn't change anything about home energy upgrades or rebates, but it does matter if you drive or plan to buy an electric vehicle: it means more fast-charging options on the road, with less worry about plug compatibility. EVgo says demand across its network has grown more than 700% over the past three years, and more than 35 EV models with the newer NACS plug are expected in the US by the end of 2026.
PSEG offers data center supply proposals in PJM’s bilateral contracting process
PSEG's power generation arm is looking to supply electricity to data centers through a new process run by PJM Interconnection, the grid operator for New Jersey and much of the mid-Atlantic and Midwest. PJM is setting up a system to line up power supply for the huge amount of electricity data centers are expected to need, including a one-time auction starting September 30 and a separate process matching power suppliers directly with data center projects through long-term contracts. PSEG's CEO said the company sees an opportunity here but gave few specifics, noting PJM's plans, including its load forecasts, are still changing. This matters to homeowners in PJM's territory because data centers are a major driver of rising electricity demand, and how utilities and grid operators handle that demand can affect what everyone pays. In a related sign of shifting demand, PJM just cut its load forecast for part of northern Illinois, reflecting a scaled-back data center pipeline there. Separately, New Jersey regulators released a report exploring possible changes to how utilities are regulated in the state, including ideas like multiyear rate plans and performance-based rates tied to results rather than just infrastructure spending. PSEG said it's encouraged by the report, which could eventually influence how utility costs and incentives are structured for New Jersey customers. The company is also sticking with its plan to spend $24 billion to $28 billion on infrastructure through 2030, mostly on replacing aging equipment, with some room for added spending on nuclear, transmission, and connecting new solar and battery projects to the grid.
The industry can’t agree on what AI demand risk is worth
This story is about who pays when massive data centers built for AI don't use as much power as expected — and it points to a cost that could eventually show up on household electric bills. Amazon recently booked a $551-million paper gain tied to long-term power contracts for data centers, some running 20 years, because it may end up paying utilities without ever using that electricity. Amazon's own filings admit the company might not need all the power it has committed to buy. Utilities are hedging against that same uncertainty. In Virginia, Dominion Energy won approval for a new rule, starting January 2027, that requires large data center customers to post $1.5 million in collateral for every megawatt of power they reserve, in case they scale back. Regulators also let Dominion earn a 9.8% return on equity (the profit rate it's allowed to charge) partly to cover this risk. Costs like this often get folded into the rates all customers pay, though the article doesn't spell out how much of it lands on households. Meanwhile, some Virginia counties hosting these data centers are pushing back directly. Loudoun County, home to the world's largest cluster of data centers, is preparing a possible moratorium on new data center approvals, to be decided in September, and just rejected a large proposed campus. Chesapeake has already paused new applications, Suffolk is rewriting its rules, and Front Royal is drafting a full ban. These moves could reshape how much data center growth happens near you, especially if you live in a fast-growing area.
The 2027 Toyota bZ Woodland EV starts at $45,000 with AWD
Toyota has priced its new 2027 bZ Woodland electric SUV starting at $45,380, plus a $1,595 delivery fee. That's $80 more than the outgoing model. A higher-end Premium trim runs $47,480. This is a rugged, off-road-leaning version of Toyota's bZ electric SUV, with extra ground clearance and towing capacity. The Woodland comes standard with all-wheel drive and dual motors putting out 375 horsepower, more power than the regular bZ. It's about 6 inches longer and 1 inch taller, with up to 74.3 cubic feet of cargo space when the back seats are folded down. Estimated driving range runs up to 281 miles on all-season tires, or 260 miles with off-road all-terrain tires. It uses a 74.7-kWh battery and can fast-charge from 10% to 80% in about 30 minutes. It also has a built-in NACS charging port, the same plug standard Tesla uses, so it can plug into a wide range of fast chargers without an adapter. The Premium trim adds a JBL sound system, ventilated front seats, a digital rearview mirror, and a glass roof with a power sunshade. Both trims include heated seats and steering wheel, wireless phone chargers, and roof rails. For comparison, Toyota's standard (non-Woodland) 2027 bZ starts lower, at $34,980. Homeowners weighing an EV purchase alongside home charging or solar plans may want to factor in this pricing when comparing options.
Study Suggests People Trust AI More That Government And Social Media
This is a general news item with no direct connection to home energy upgrades, so there is nothing here to act on for your house. A new survey from the Collective Intelligence Project, based on interviews with more than 6,000 people in 70 countries, found that 58 percent of respondents trust AI chatbots more than their own elected officials. AI ranked above faith leaders, corporations, and civil servants, with only family doctors and public research institutions scoring higher. Nearly 40 percent said an AI system would weigh their interests more fairly than a person would, and 37 percent said AI could make better decisions on their behalf than their government representatives. The trust drops off, though, when it comes to letting AI actually make decisions rather than just offer information. Only about 3.7 percent of people said they'd let an AI make choices for them outright, even though nearly half liked the idea of AI helping with local decisions like taxes, permits, or licenses. Researchers quoted in the piece suggest this comfort with AI stems partly from long-declining trust in government and partly from chatbots seeming patient, available, and neutral in ways politicians rarely do. None of this affects specific programs, rebates, or technology choices for homeowners. It's simply a snapshot of how people worldwide are starting to relate to AI as a source of information and, increasingly, a stand-in for institutions they no longer trust.
How gamification can nudge employees to act more sustainably
This story is about labs and pharmaceutical companies, not homes, but it touches on an idea worth knowing: freezers are big energy users, and small temperature changes can save a lot of power without hurting what's stored inside. Pharma companies AstraZeneca and Amgen were among the winners of a competition called the Freezer Challenge, where more than 4,000 laboratories across nearly 270 organizations saved almost 30 gigawatt hours of energy. They did it mainly by resetting freezers that store biological samples from the industry-standard minus 80 degrees Celsius to minus 70 degrees, along with better maintenance of freezer parts. The change reportedly has no effect on most samples. One estimate in the story: a single lab freezer can use as much energy as two American homes. Amgen and AstraZeneca were recognized for daily savings of over 5,000 kilowatt-hours each during the first half of 2026. Other winners included Siemens Healthineers in the hospital category and the U.K.'s Institute of Cancer Research in the academic category. The takeaway for a home isn't about your own freezer setting, but the underlying point applies broadly: appliances that run constantly, especially ones set colder than they need to be, can waste a surprising amount of energy. If you're looking at your own home's energy use, checking whether any appliance is set colder or runs harder than necessary is a similar, low-cost way to find savings.
Trump EPA Plan to Put Louisiana in Charge of Toxic Coal Ash Threatens Drinking Water
The Trump administration's EPA is planning to hand oversight of Louisiana's coal ash waste to the state's own environmental agency, rather than keeping federal enforcement in place. Coal ash is the waste left over from burning coal at power plants, and it contains arsenic, mercury, lead, and other heavy metals linked to cancer and other serious health problems. Environmental groups, including Earthjustice and the Sierra Club, are pushing back, pointing to groundwater testing at all three of Louisiana's active coal plants near Baton Rouge, Alexandria, and Shreveport, plus one retired plant, that found contamination above federal safe drinking water limits. More than 61 percent of Louisiana residents rely on groundwater for some or all of their drinking water. The groups argue the state's environmental agency has a poor track record on this issue, including letting coal plants close ash dumps while ash remains in contact with groundwater, which can keep contaminating water supplies indefinitely. Critics say the agency is understaffed, lenient with polluters, and has been faulted for weak air monitoring and permitting decisions in the past. This is a policy fight over who regulates coal ash sites in Louisiana, not a new requirement or rebate program for homeowners elsewhere. If you live near a coal plant in Louisiana or get drinking water from groundwater in the state, this is worth watching, since it could affect how closely toxic waste sites near you get monitored going forward.
The Elusive Dream Of Solar Powered EVs Is Not So Elusive After All
A startup called Aptera is moving closer to selling a solar-powered electric vehicle, though it comes with a catch: it has three wheels instead of four. That design counts as an "autocycle" under US rules, which means drivers can use a regular license instead of a motorcycle license. It also means the car, called Atlas, qualifies for HOV (carpool) lane access in California even with just one person aboard, since three-wheeled vehicles are allowed in those lanes regardless of passenger count or fuel type. That access isn't a temporary incentive program, unlike California's old Clean Air Vehicle sticker program for single-occupant EVs, which ended last September. The solar panels built into the car's body can add real range without plugging in. In tests, parking the car in one spot facing east or west picked up around 40 miles worth of charge over a sunny day, and repositioning it as the sun moved added a bit more. Even on a cloudy day, repeated repositioning still pulled in about 36 miles of range. Aptera has cleared one federal hurdle, earning an EPA emissions certificate, and still needs a federal safety certification before it can sell cars. It has also started ordering parts for its first 40 production vehicles, expected at its California factory this fall. Reservations are open for $100, with a target price of $40,000 for a 400-mile version, and other options ranging from $28,000 for 250 miles up to $55,000 for 1,000 miles.
A controversial plan to update Line 5 just suffered a major loss at the Michigan Supreme Court
The Michigan Supreme Court has thrown out a key permit for a project to replace part of the Line 5 oil pipeline, which runs under the Straits of Mackinac between Lake Michigan and Lake Huron. Enbridge Energy wanted to replace an aging section of the 73-year-old pipeline with a new one encased in a tunnel under the lakebed. The court ruled 6-1 that the Michigan Public Service Commission, which had approved the permit in 2023, failed to look at the full range of environmental harm and didn't properly weigh the public's right to use the Great Lakes, a protection known as the public trust doctrine. The case now goes back to the commission for a more thorough review, adding more delay to a project that's already been tied up for years. The ruling matters beyond this one pipeline segment. The court said regulators must consider how the tunnel project would affect the entire 645-mile pipeline, not just the new tunnel section, including whether it extends the pipeline's life and what that means for spill risk and the environment. Opponents, including tribal nations and environmental groups, say this opens the door to a broader conversation about shutting down Line 5 entirely, rather than just approving the replacement segment. Enbridge says it's reviewing the decision and remains committed to operating the pipeline safely. This case is separate from other legal fights over whether Line 5 can keep operating in the straits at all, which are still working through Michigan courts.
Ørsted adds 500 MWh of Tesla BESS to ERCOT grid
A large battery storage project has come online in Needville, Texas, part of the ERCOT grid that serves most of the state. Ørsted's Old 300 Storage facility can hold 500 megawatt-hours of power using Tesla battery packs (called Megapacks), built in Lathrop, California. It sits alongside an existing 430-megawatt solar farm, Old 300 Solar, which has been powering roughly 80,000 homes and businesses since 2024. The battery system runs separately from the solar farm and is designed to release stored power when demand on the grid is high, such as during heat waves or cold snaps. For homeowners in Texas, this kind of project is part of a broader effort to keep the grid steady during periods of strain, when supply and demand run close together. Battery storage like this doesn't power your house directly, but it adds a buffer that can reduce the risk of outages during peak stress on the system. The combined solar and storage project is also expected to generate about $110 million in property tax revenue over time, money that goes toward local infrastructure, schools, and emergency services in the area. There's no direct rebate or program tied to this project for individual homeowners. It's a utility-scale addition to the grid, not a residential energy upgrade. But for anyone in the ERCOT service area, more battery storage on the grid generally means more reliable power supply as electricity demand keeps growing.
Tesla Megapacks power Ørsted’s big new Texas grid battery
A large new battery has come online in Texas, and it's built with Tesla hardware. Ørsted, the energy company, just connected a 250 megawatt battery storage project called Old 300 Storage to the state's power grid (ERCOT), near Needville southwest of Houston. At full power, it can supply 250 megawatts for two hours before needing to recharge, using Tesla's Megapack units, which come pre-built with batteries, inverters, and cooling systems all in one package. This isn't a home battery story, but it does affect grid reliability where you live if you're in Texas. Batteries like this one charge up when electricity is cheap or plentiful and discharge when the grid is strained, which helps during extreme heat or cold when demand spikes. The battery sits next to Ørsted's Old 300 Solar farm, which has been running since 2024 and generates enough power for about 80,000 homes and businesses, but the two operate independently. The battery can pull from and send power to the wider grid, not just the solar farm. Together, the solar and battery projects are expected to bring in around $110 million in property tax revenue for local schools and services. The addition also grows Ørsted's US onshore energy portfolio to about 6 gigawatts, and adds to Tesla's fast-growing business supplying grid-scale batteries.
Electrovaya unveils 7 MW containerized battery system targeting AI data centers
A company called Electrovaya has introduced a new large-scale battery system called the ElvaPulse 1500, built to supply power to data centers and AI computing facilities, which use large and unpredictable bursts of electricity. The battery sits inside a standard shipping-container-sized unit and can store nearly 2.88 megawatt-hours of energy while delivering about 7 megawatts of continuous power. It's designed to release that power quickly, in bursts of under 30 minutes, rather than the slower 2- to 4-hour discharge common in typical utility-scale batteries. This isn't a product for homes. It's aimed at large facilities like data centers, industrial sites, and "microgrids" — localized power systems that can operate independently from the main electric grid. The company says the compact, high-power design could also help with things like smoothing out fluctuations from solar or wind power and managing peak electricity demand. Electrovaya expects to start commercial deliveries in the second quarter of 2027 from its factory in Jamestown, New York. The system is still going through two safety certifications, UL 1973 and UL 9540, which are standards for battery storage safety, with completion expected by early 2027. The company is currently taking reservations from potential business customers. For homeowners, this development mainly reflects the broader push to build more battery storage to meet rising electricity demand from AI and data centers. It doesn't involve any home battery products or rebates, but it's part of the same wave of energy storage investment that is reshaping how power grids handle demand.
Trump’s Biomass Bug Is Coming Back To Bite Fossil Fuels
This is mostly national energy policy news, not something that touches your house directly, but it helps explain where energy dollars are flowing right now. Plant-based fuel made from crops and waste oils is expanding fast in the jet fuel market. A federally backed plant in Great Falls, Montana got a $1.67 billion loan guarantee to eventually produce 300 million gallons a year of sustainable aviation fuel, made from things like animal fat, used cooking oil, canola oil, and camelina (a winter oilseed crop). A separate Minnesota project aims for 1 billion gallons a year, helped by a $1.50-per-gallon state tax credit, and just finished a blending facility near the Minneapolis airport. Delta and Shell are also expanding aviation fuel partnerships to airports in Los Angeles, Portland, New York, and Boston. None of this changes home energy programs or rebates. But it shows a pattern worth knowing: this kind of biomass fuel is finding real traction in aviation and vehicles, even under an administration that has otherwise cut clean energy funding. The same fuel does not work for producing electricity — the article notes that biomass power plants remain a tiny sliver of new grid projects and are expected to shrink further nationally. For homeowners, the practical takeaway is limited. This is fuel for planes and cars, not something that affects your furnace, water heater, or electric bill directly. If you are tracking federal energy priorities to guess at future rebate funding, this signals that liquid biofuels have more political staying power right now than some other clean energy categories.
Tesla is suing this Canadian province for cutting it out of its EV incentives
Tesla is suing the Canadian province of Manitoba after being cut out of its electric vehicle rebate program. Manitoba's rebate, launched in 2024, offers up to $4,000 off a new EV under $70,000 and $2,500 off a used one. In its March 2025 budget, the provincial government dropped Tesla and Chinese-made vehicles from eligibility, with officials saying the move was tied to tensions over U.S. tariffs and Elon Musk's support for President Trump. Tesla says this has already cost its Canadian customers at least $560,000 in lost rebates, despite Tesla having been the single biggest recipient of the program before the ban, accounting for more than 20% of all rebates paid out. Tesla argues the exclusion was unfair and untransparent, noting it was never given a formal explanation and that no other automaker with a U.S. parent company was removed from the program. It's asking the court to reinstate it and pay retroactive rebates to affected buyers. Tesla has won a similar case before: in 2018, a court ruled against Ontario for structuring a rebate wind-down in a way that excluded Tesla. This case doesn't directly change anything for U.S. homeowners, but it's part of a broader pattern. British Columbia, Nova Scotia, and Prince Edward Island have also excluded Tesla from their EV rebates in 2025 over similar trade tensions, and a Tesla win in Manitoba could set a precedent affecting rebate eligibility rules across other Canadian provinces.
Op-Ed: Pax Silica Could Complicate Philippine & Regional Sustainable Energy Goals
The Philippines is weighing whether to join Pax Silica, a US-led effort to build trusted supply chains for semiconductors and AI hardware among allied nations. The plan centers on a proposed tech and manufacturing zone in New Clark City that would need at least 5,000 megawatts of electricity. Current plans only provide 1,700 megawatts, from a 500-megawatt solar facility and a 1,200-megawatt natural gas plant, leaving a 3,300-megawatt gap that would have to come from the Luzon power grid. Pulling that much power from the grid would eat deeply into its current reserve margin, raising the risk of supply problems, higher electricity prices, and more reliance on fossil fuels to keep the grid stable. Clean alternatives like offshore wind and grid-scale battery storage can't fill the gap fast enough: offshore wind takes up to a decade to build, and even the world's largest battery storage systems could only power a load this size for a few hours before needing to recharge. Small modular nuclear reactors are still rare and unproven at this scale. Water is another concern, since chip manufacturing and data centers use enormous amounts of it, and the site's projected water supply may not keep up if multiple facilities operate at once. This is a policy and industry story about how the Philippines plans its power grid and industrial growth, not something that changes any programs, incentives, or rebates available to homeowners here.
Which LDES companies are poised to land the next big contracts?
This is industry news about grid-scale batteries, not something that touches individual homes, but it's worth knowing about since it shapes how the power grid gets cleaner and more reliable over time. Long-duration energy storage (LDES) refers to big batteries and similar systems that can store electricity for many hours, helping the grid handle spikes in demand from things like data centers. The sector is growing fast: after a breakout 2025, when 33 megawatts came online globally, this year is expected to bring hundreds of megawatts into service. Most of that growth is still coming from lithium-ion batteries, which tend to win government contracts on cost and readiness. But non-lithium technologies are gaining ground too, especially with large power users like tech companies that care more about steady supply chains than rock-bottom price. Energy Dome, which makes carbon-dioxide batteries, has landed high-profile deals, including one with Google. Form Energy, maker of iron-air batteries, is climbing the ranks as the cost of its big Pine Island project with Xcel and Google comes down; it's also reportedly considering an IPO. Behind those two leaders, a second wave of companies is positioning itself for future contracts. Hydrostor, a Canadian compressed-air storage company, has a large project pipeline and could get a credibility boost if its flagship California project reaches a final investment decision. Invinity Energy Systems, a British vanadium-flow battery maker, recently won its biggest contract yet and is building U.S. manufacturing. Sage Geosystems, which combines geothermal technology with energy storage, is smaller but could benefit as buyers start prioritizing reliability over cost alone.
GM will begin shipping electric Buick vehicles from China overseas, starting with this SUV
GM and its Chinese partner SAIC are extending their joint venture for another 20 years, through 2047, and plan to start exporting Buick electric and hybrid vehicles from China to markets outside the country. The first model heading overseas will be the Buick Electra E7, a midsize plug-in hybrid SUV, starting in October. GM hasn't said whether the US is one of the markets that will get these vehicles — the export plan mentioned so far covers the Middle East, Africa, South America, Mexico, and the Asia-Pacific region. The E7 runs on a 1.5-liter engine paired with an electric motor and a 32.6 kWh battery. On electric power alone it's rated for about 143 miles of range, with a combined gas-and-electric range of over 1,000 miles under Chinese testing standards. In China, it starts around $23,000 to $28,900. The cabin includes features like a large touchscreen, reclining seats, a rear entertainment screen, and a built-in refrigerator — a step up in luxury from what Buick has typically offered. For homeowners weighing an electric or plug-in hybrid vehicle alongside upgrades like home EV chargers or solar, this is worth watching but doesn't change anything yet. Nothing here confirms US availability, pricing, or a launch date for American buyers, so there's no new option on the table for now — just a sign that Buick's electric lineup is expanding and looking for buyers beyond China.
NYC Council preparing nearly 20 new e-bike laws and restrictions
This one is off topic for home energy upgrades, but here's what happened in case it matters to you as a New York City resident. New York City Council members have proposed 17 new bills aimed at regulating e-bikes, e-scooters, and other micromobility vehicles, following a rise in crashes involving these vehicles and cars or SUVs. The proposals still need committee hearings and months of debate, with hearings expected to start this fall. The package includes a ban on selling Class 3 e-bikes (a category currently allowed in the city but capped at 25 mph), new commercial licensing requirements for delivery companies, rules requiring companies to share more rider data and carry added insurance, and stronger penalties for hit-and-run riders. Other bills would step up enforcement against illegal electric mopeds and high-powered vehicles disguised as bicycles, set up a trade-in program for illegal vehicles, and form a task force to study street design changes. Notably, the package does not include a much-debated plan to require license plates and registration for all e-bikes and scooters. City leaders say the focus is on holding delivery platforms accountable rather than penalizing individual delivery riders, of which the city has roughly 80,000. This is a New York City policy story, not a home energy matter, so it has no bearing on heat pumps, insulation, or rebate programs.
Michigan winemakers have a new climate worry: More wildfire smoke
This is a story about agriculture and climate, not home energy upgrades, but here's the plain-language summary. Wildfire smoke from fires burning in Canada and Minnesota drifted over northern Michigan's wine country last month, turning the sky a hazy pink over vineyards on the Leelanau and Old Mission peninsulas. Winemakers there worry about "smoke taint," a problem where grapes exposed to smoke for a long stretch pick up unwanted flavors, described as anything from barbecue to burnt bacon, once the wine ferments. Michigan's wine industry is valued at nearly $9 billion. This time, growers caught a break. The grapes were still in an early, hard, pellet-like stage of growth called "buckshot berry stage," and experts say fruit is most vulnerable to smoke damage later in the season, when the berries change color in the fall. A Michigan State University viticulture professor said he's confident the smoke exposure wasn't long or heavy enough to affect this year's grapes, though there's no way to test for damage until the wine is actually made. The bigger worry is the trend: as climate change drives hotter, drier summers and more wildfires, smoke exposure is becoming a growing threat to wine regions worldwide, including Bordeaux, France, where fires have burned close to vineyards. Scientists say there's no easy fix for smoke taint, and one Michigan grower put it simply: farming here now means adapting to more unpredictable weather and new hazards, wildfire smoke among them.
BYD Commercial Vehicle Sales Jumped 149% in July
Chinese automaker BYD reported strong growth in electric commercial vehicle sales for July. Sales of electric buses hit 620 units, up about 91% from June, though only slightly higher than a year earlier. Sales of other electric commercial vehicles, like delivery vans and trucks, reached 7,519 units, up about 28% from June and up 183% compared to July of last year. Combined, BYD sold 8,139 electric buses and commercial vehicles in July, a jump of nearly 150% from the same month last year. This news is about the commercial side of BYD's business, covering vehicles like buses and trucks rather than the cars people drive at home. It does not point to any new program, rebate, or product aimed at homeowners. Still, it is a sign of how quickly electric vehicles are spreading beyond passenger cars, into fleets, transit systems, and delivery services. As more of these vehicles hit the road, it can shape the broader market for EV batteries, charging equipment, and related technology, some of which eventually filters down to home charging options and costs. For now, though, this particular update is about BYD's business performance, not something that changes what a homeowner can buy or claim in rebates today.
Kia’s electric van is crushing it in Europe with a 37% share of small EV van sales
This one is about vehicles, not home upgrades, but here's the gist. Kia's new electric van, the PV5, has become the top-selling small electric van across Europe and the UK since it launched at the end of 2025. Industry data shows it now holds 37% of the small electric van market in Europe and ranks as the best-seller in 12 countries, including the UK and Germany. The PV5 comes in a few versions: Cargo (for hauling), Passenger, and Chassis, aimed at both businesses and personal buyers. In the UK, the Cargo version is the best-selling electric van so far this year, and Kia sold over 1,000 electric vans there in July alone. That performance has pushed Kia into third place among electric van makers in the UK, and Kia is now the second-most-popular electric vehicle brand overall in the country. Kia plans to expand the lineup with new PV5 variants, including a seven-seat passenger model, and to introduce a larger van (the PV7) next year, followed by another model by 2030. The company aims to sell 232,000 of these electric work vans by the end of the decade. For homeowners, this is mostly relevant if you're watching the broader shift toward electric vehicles, since vans like this often show up as delivery or service vehicles from contractors and utilities. It doesn't involve home energy upgrades, rebates, or equipment for your house.
BYD Achieves Record Exports With 124% Growth
This is car industry news, not a home-upgrade story, but here's what happened. BYD, the Chinese electric vehicle maker, had a strong July, with passenger vehicle sales up 20.5% and battery-electric vehicle sales up 31%, its second-best month ever for that category. Most of that growth came from outside China rather than inside the country, where the car market, including EVs, has been soft this year. The company exported 180,538 vehicles in July, its highest monthly total ever and about 5,000 more than the previous record of 175,349 set in June. That's 3% higher than June and 124% higher than July 2025, when exports were 80,737. BYD's overseas sales have been climbing steadily for months as the company expands into more markets abroad. For a homeowner, this doesn't change anything about energy upgrades, rebates, or your house directly. It's a sign that Chinese-made EVs are becoming a bigger part of car markets outside China, which could matter down the road if it affects EV prices, availability, or charging infrastructure investment in your area. But there's no rebate, deadline, or program tied to this news that touches your home right now.
BYD BEV Sales Rise 31% in July!
BYD, the world's largest electric vehicle maker, posted strong sales growth in July. The company sold 411,072 passenger vehicles worldwide, up 20.5% from July 2025 and up 3.5% from June. Battery-electric vehicle sales, meaning cars powered only by a battery rather than a gas engine, rose 31% year over year to 233,105, making it the second-best month ever for that category. Plug-in hybrid sales, which combine a battery with a gas engine, rose 9.1% from a year earlier but slipped 9.1% from June, landing at 177,967. Despite the strong July, BYD is still down for the year overall. Across the first seven months of 2026, total plug-in vehicle sales are down 10.8%, battery-electric sales are down 8.4%, and plug-in hybrid sales are down 13.2% compared with the same period last year. New models are reaching the market and supply issues appear to be easing, which points toward more growth in coming months. This news is mostly a snapshot of the global EV market rather than something that changes what's available to a homeowner right now. BYD is not a major brand in the U.S. market, so this sales surge is more relevant to buyers in China and other regions where BYD sells directly. If you're weighing an electric vehicle purchase alongside home upgrades like a charger or solar panels, it's still worth checking which EV brands and models are actually sold and supported where you live before this kind of global sales trend affects your options.
Waymo Launches Robotaxi Service in Dallas
This news is about self-driving cars, not home energy upgrades, so it doesn't affect your house or any rebate programs. Waymo, the robotaxi company, has opened its ride-hailing service to everyone in Dallas after months of limited testing with an interest list of nearly 150,000 riders. People in the city can now download the Waymo app and hail a car with no human driver. Waymo also said it plans to expand where its cars can go in the Dallas area. It's testing rides to and from terminals at Dallas Love Field Airport and testing on Dallas freeways, both steps toward eventually offering those routes to the public. A local advocacy group, Epilepsy Foundation Texas, said the service could help people who can't drive due to medical conditions get around more independently. None of this involves your home, your utility bills, or any weatherization or rebate programs. If you're in Dallas and curious, this just means a robotaxi option is now available citywide rather than only to people on a waitlist. For everyone else, it's simply a sign that Waymo continues rolling out its service to more cities in stages, moving from testing to limited access to full public service.
BYD undercuts luxury rivals with its first 7-seat premium MPV in the UK
This is a car story, not a home energy upgrade story, so it doesn't affect your house directly. But it's worth a quick mention: BYD's luxury brand Denza launched the D9, a seven-seat plug-in hybrid minivan, in the UK. Prices start at £75,000 for the Elegance trim and £85,000 for the Ultimate trim, both undercutting the Lexus LM hybrid, which starts around £97,645. The D9 uses a plug-in hybrid setup with two electric motors and a 1.5-liter gas engine that mainly works as a generator. Its 58.5 kWh battery gives about 130 miles of pure electric range, with a combined gas-and-electric range up to 590 miles. BYD's fast-charging tech can take the battery from 10 to 70 percent in five minutes, and from 10 to 97 percent in nine minutes, even at very cold temperatures. None of this connects to home energy upgrades or rebates. If you're weighing an EV or plug-in hybrid purchase alongside home electrification, the main thing to note is that plug-in hybrids like this one still have a gas engine and tank, so they don't eliminate fuel use the way a fully electric vehicle would. If you're also thinking about installing a home EV charger, the type of vehicle you choose, plug-in hybrid or full electric, affects how much charging capacity you actually need at home.
New Denza Z9S Breaks Range & Handling Records At Average US Car Price
This is a heads-up on a new electric car, not something tied to home energy upgrades, but worth knowing about if you're weighing an EV purchase alongside other household changes. BYD's Denza brand just launched the Z9S sedan in China, and it's notable mainly for value: it starts at roughly $47,000, close to the average new-car price in the US ($49,758 as of June). For that price, it claims a record 684 miles of range on the Chinese CLTC test cycle, plus a fast-charging battery (LFP type) that can add hundreds of miles of range in about 5 to 9 minutes and can be routinely charged to 100% without the battery wear concerns some other EV batteries have. The car also set a record on the "moose test," a standard obstacle-avoidance handling test, outperforming cars costing far more. BYD frames all this range and speed as a way to make owning an EV feel as worry-free as a gas car — enough range and fast enough charging that most drivers won't think about it day to day. None of this is available in the US yet — it's a China-market launch, and the article notes that American car buyers currently have fewer EV options and higher prices, with more advanced Chinese EV technology largely absent from the US market due to trade barriers. Still, it's a sign of how quickly EV range, charging speed, and price are improving elsewhere, which may eventually shape what becomes available closer to home.
Basketball Superstar Yao Ming Receives His NIO ES9
This news is about a Chinese luxury electric SUV, not about home energy upgrades or rebates, so there's nothing here for you to act on around your own house. Basketball star Yao Ming recently took delivery of a NIO ES9, an electric SUV made by the Chinese automaker NIO. He placed his order within minutes of launch but still waited two months for the vehicle, since demand has been running well ahead of production. NIO's ES9 is close to reaching 20,000 total deliveries, and wait times for higher-end trims of a related model, the ES8, run 13 to 14 weeks, with even the cheapest trim carrying a 3-to-4-week wait. The ES9 starts at 498,000 yuan (about $73,777), or 390,000 yuan (about $57,777) if the buyer leases the battery separately rather than buying it outright. Deliveries began on May 28, and NIO hit its 10,000th delivery about a month later, on June 26. For homeowners tracking the electric vehicle market as part of broader energy decisions, like whether to add a home charger or solar panels, this mainly signals strong demand for high-end EVs in China. It doesn't involve any U.S. rebate program, tax credit, or home energy upgrade, and NIO vehicles aren't sold in the United States. If you're weighing an EV purchase or charger installation for your own home, this particular story doesn't change anything about what's available or affordable where you live.
Segway Xafari e-bike new $1,500 low ($900 off) + Xyber e-bike new $2,300 low ($1,000 off), EcoFlow flash sale, ECOVACS, more
This roundup covers e-bike and home energy gear deals, most of it not directly tied to home energy efficiency upgrades or rebates. Segway's Xafari All-Terrain Smart Cruiser e-bike has dropped to a new low of $1,500, which is $900 off, while the pricier Xyber Electric Bike is at a new low of $2,300, a $1,000 discount. For homeowners with backup power or off-grid interests, EcoFlow is running a 48-hour flash sale. The standout is a 3,600Wh DELTA Pro Portable Power Station bundled with two 220W solar panels, priced just $7 above its all-time low. There's also a robot lawn mower deal: the ECOVACS Goat O1000 RTK Robot Mower, bundled with 36 replacement blades, is down to $664. On the yard-tool side, an EGO bundle pairing a 15-inch string trimmer with a 530 CFM leaf blower has hit a 2026 low price. Ongoing deals on power stations from Jackery and Bluetti are also mentioned, along with leftover deals from earlier in the week. None of this is tied to a specific rebate program, utility incentive, or energy-efficiency upgrade like insulation, heat pumps, or air sealing. It's mainly retail pricing on e-bikes, portable power stations, solar panels, and outdoor power equipment. If you're already considering a solar-plus-battery setup for backup power, or looking at electric yard tools, these price drops might be worth a look, but they don't reflect any change in rebate eligibility or program rules for home upgrades.
Court rules against Trump EPA’s freeze of $20B in ‘green bank’ funds
A federal appeals court has ruled that the EPA broke the law when it froze $20 billion in "green bank" funding last year. That money, created under the 2022 Inflation Reduction Act as the Greenhouse Gas Reduction Fund, was meant to boost lending for clean energy and efficiency projects, especially in communities that have had trouble getting financing for them. The EPA still has a chance to appeal to the Supreme Court, and the agency's administrator has said he intends to keep fighting to claw the money back, so the funds remain frozen for now. The freeze has already stalled real projects. One group awarded $7 billion, Climate United, had lined up financing for things like solar power at the University of Arkansas, electric trucks for small trucking companies in California, building upgrades to make homes and other buildings more efficient, and clean energy projects on tribal land. Only a small part of that money had gone out before the freeze hit, and the group has had to cut staff while the case dragged through court. For homeowners, this doesn't change any rebate or incentive you can apply for today. But it matters because green bank money was designed to expand affordable financing for home energy upgrades, particularly in lower-income and underserved areas, and that pipeline stays on hold until the legal fight ends. A separate $7 billion pot for the Solar for All program, aimed at low-income solar, was also cut by the EPA and is being challenged in court on its own track.
Massachusetts embraces backyard homes as housing and climate solution
Massachusetts homeowners are getting new help to build accessory dwelling units, or ADUs — small backyard homes, garage apartments, or in-law suites. A 2024 state law made ADUs legal in nearly every city and town (Boston is the exception) and limits how much local rules can restrict them, though towns can still set their own property-line setbacks, septic rules, and height limits. In 2025, over 1,200 ADUs got permits statewide, still short of the state's goal of 1,600 to 2,000 a year through 2030. Two new programs aim to make the process easier. The Massachusetts Housing Partnership connects homeowners with providers who charge no more than $500 for a feasibility study covering zoning limits, utility needs, design, and a rough cost estimate. Building an ADU typically runs $120,000 to $450,000, depending on size and whether it's new construction or a conversion. The Massachusetts Clean Energy Center offers a free online tool, the ADU Wizard, that lets you look up your own property, see whether an ADU could work there, and test different layouts. In the Pioneer Valley region of western Massachusetts, a separate program offers one-on-one guidance and a list of manufactured-home suppliers. The state also introduced a low-cost financing program for ADUs in March. Beyond adding housing, many ADUs are built all-electric and highly efficient, some using factory-built, airtight construction, which can mean lower energy bills. If you're considering one, your town's specific zoning rules will still shape what's possible on your property.
Battery-eligible New Jersey VPP program begins to take shape
New Jersey is putting together a program that would let home batteries earn money by helping the power grid. The state's Board of Public Utilities released a proposal in July for a two-year "virtual power plant" program — a system that links up home batteries and other small devices so utilities can call on them together, like one big power plant. It would start by mid-2027 and be run by the state's four electric utilities, before shifting to an open, ongoing program in 2029. The Board is taking public comments on the plan through August 17. One utility, PSE&G, said it plans to launch its own battery program this month, offering homeowners about $5,000 upfront toward an 8-kilowatt home battery, with the rest financed through the company's on-bill repayment plan. In exchange, PSE&G would be able to draw power from the battery during high-demand periods. The utility says it may later add ongoing payments for customers who already own batteries. A related pilot in Delaware, run by Pepco's parent company, pays participating customers around $1,080 a year by direct deposit for letting the utility control their battery, and the company is considering bringing a similar program to its New Jersey customers. None of this is final yet — it is still in the planning and comment stage — but it points toward more homeowners in New Jersey having the option to get paid for letting a utility use their home battery during peak demand.
America’s permitting crisis lives at City Hall
This is an opinion piece from a home battery company executive about how city permitting rules, not federal policy, are the biggest holdup for home energy projects like batteries and solar. The writer compares two nearly identical home battery installs, eight miles apart: one was approved online in an afternoon and cost $45, while the other took twelve weeks, three trips to city hall, two in-person inspections, and cost $992. Same battery, same installers, wildly different local rules. The piece argues these local "soft costs" — permitting fees, inspections, paperwork — now make up a huge share of what homeowners pay for solar, citing a figure of 78%. It points to Australia, where installers are accredited rather than every project being individually reviewed, and where a 10-kW solar system costs around $5,700 versus $19,000 to $27,000 in the U.S. The writer says the batteries involved already carry a national safety certification (UL 9540) before installation, so lengthy local review adds delay without adding safety. The piece calls for national standards, faster online permitting tools like the Department of Energy's SolarAPP+, and state-level fixes already tried in Florida and Texas that set permit deadlines or standardize battery rules across cities. For homeowners, the takeaway is that how fast and how much you pay to permit a home battery or solar system can depend heavily on your specific city's rules, not just the equipment or installer — and that gap can be large.
Supermarkets Turning to A2Ls for Low-GWP Refrigeration
Grocery store chains are shifting to a new type of refrigerant to meet an EPA rule that limits the use of older chemicals with a high global warming impact. The refrigerant getting the most attention is called A2L, a mildly flammable, lower-impact option that fits into system designs similar to what stores already use. That familiarity is the draw: A2L systems cost less to install and are easier to maintain than an alternative approach using CO2-based refrigeration, which has also been gaining ground but requires more different equipment and know-how. This is a commercial story about supermarket refrigeration, not home HVAC equipment, so it doesn't change anything about your furnace, air conditioner, or heat pump directly. But it's part of the same broader shift you may notice elsewhere: refrigerants with lower environmental impact are becoming standard across cooling equipment, including some newer home air conditioners and heat pumps, as older refrigerants get phased out under the same kind of EPA rules. If you're planning a cooling upgrade at home, it's worth knowing that refrigerant type is one more thing changing across the industry right now, alongside efficiency and rebate rules. It doesn't require any action on your part, but it helps explain why some new HVAC equipment on the market looks and is labeled differently than what you might be used to.
$700M microgrid bill has state energy office, electrical manufacturer support
A new bill in the Senate would put $700 million toward microgrids, the small local power systems (often paired with solar panels or battery storage) that can keep homes and businesses running during outages by disconnecting from the main grid. Sen. Peter Welch of Vermont introduced the STRONG GRID Act, which would direct $200 million to a Department of Energy pilot program and $500 million to state grants over the next year. For homeowners, the state grant money is the part worth watching. It would let state energy offices fund microgrid feasibility studies, design work, construction of generation and battery storage equipment, and cybersecurity upgrades. The bill doesn't create a program for individual households to apply for money directly, but if your state sets up a grid resilience program under this law, it could support local microgrid projects, such as ones serving a neighborhood or town, that make outages less disruptive where you live. The bill has backing from the National Association of State Energy Officials, the GridWise Alliance, and electrical equipment manufacturers, who argue it would help protect communities as extreme weather strains the power grid and demand keeps rising. Supporters say microgrids offer a faster way to add resilience in high-risk areas than upgrading traditional power lines, which can take years. The bill has just been introduced, so it still needs to pass Congress before any of this funding becomes available. Whether it affects your area will depend on whether your state applies for and sets up a program under it.
Unlocking HVAC Efficiency: Smart Coil and System Design
This piece is aimed at engineers who design heating and cooling systems, but the underlying ideas explain why some HVAC equipment runs more efficiently than others. One point: coils (the finned parts that transfer heat) work better with fewer fins packed per inch, because that lets air move through with less resistance, which cuts energy use and makes the coil easier to keep clean over time. Ductwork matters too. Designing ducts for a lower pressure drop, and using gentler turns and transitions, reduces the fan energy needed to push air through your home. The bigger point is about sizing equipment correctly. Installing oversized boilers or furnaces raises upfront cost, energy use, and maintenance needs. The article gives an example: rather than three large 600 MBH boilers, a system with three smaller 500 MBH boilers plus one small 250 MBH boiler can cover the same heating load while running more hours at peak efficiency, because equipment can be staged on and off to match demand instead of running oversized units at partial capacity. None of this changes what a homeowner needs to do right now, but it's useful background if you're ever replacing a furnace, boiler, or central air system. The details matter less than the general principle: equipment sized to your home's actual heating and cooling load, with attention to ductwork design, tends to run more efficiently and cost less to operate than an oversized system chosen mainly for peak-day capacity.
Data centers take center stage in Wisconsin governor’s race
Data centers have become a major issue in Wisconsin's governor's race, and the outcome could affect electricity bills across the state. Developers have flocked to Wisconsin for its cool climate, water access, and tax breaks, but the huge power demand from these facilities has raised fears about rising utility bills and new fossil-fuel plants built to serve them. A recent poll found over three-quarters of Wisconsin voters now think the costs of data centers outweigh the benefits. One utility, We Energies, is planning two new gas plants partly to meet this demand, while some coal plants slated for retirement are staying online longer than planned. Democratic candidates in the Aug. 11 primary have proposed various fixes: a moratorium on new data centers, requirements that they bring their own clean energy, taxes on developers to fund clean energy loans, and more reporting on how much power big users consume so regular customers aren't subsidizing them. Republican candidate Tom Tiffany wants to block data centers on farmland and end their tax breaks, but favors keeping old coal plants running rather than requiring clean energy. For homeowners, the relevant piece is rate protection. State regulators recently created a special electricity rate for data centers in the Milwaukee area specifically to keep regular customers from covering the cost of powering them, a move consumer advocates praised. How this race unfolds could shape whether that kind of protection expands, and whether new power plants built for data centers end up affecting your own utility bill.
