The Messaging Skills That Have Blown Up The AI Bubble
This isn't home energy news. It's a commentary piece arguing that the hype around AI chatbots and humanoid robots relies on a handful of persuasion tricks rather than proven results. The author's point: personifying AI as human-like minds, promising a utopian "age of abundance" where no one needs to work, framing AI as a mysterious "black box" that might even become conscious, and making inflated claims about AI's abilities have all fueled investment and public excitement well beyond what the technology can currently deliver. There's nothing here about home upgrades, rebates, heat pumps, insulation, or any program a homeowner could use. The piece is a broader opinion piece about AI industry hype and doesn't touch on energy efficiency, weatherization, or household costs at all. If you're weighing energy-efficiency decisions for your own house, this article won't help with that directly — it's worth knowing only as general context on how tech hype cycles get built, in case that shapes your view of any "smart home" or AI-powered gadgets marketed alongside energy upgrades. But the specific claims, dollar figures, and eligibility details you'd want for planning a retrofit aren't part of this story.
Forbidden fruit: Buick Electra gets 435 mile range and 376 hp for $25,000
GM's Buick brand has unveiled a new electric sedan, the Electra L7, for the Chinese market, and it is drawing attention for its price and range. The car uses a battery supplied by CATL, offering roughly 436 miles of range on the Chinese testing cycle, paired with a 376-horsepower electric motor. Pricing starts around $25,170 in US dollars, which is notably low for a car with this range and power. The Electra L7 comes with features like a heated steering wheel, wood-grain trim, ambient lighting, a three-zone climate system, a premium sound system, and wireless phone charging. Higher trims include a driver-assist system that combines lidar, radar, and cameras for a fuller view of the road, similar to advanced systems used by other automakers. There is no indication this car will be sold in the United States as is. It is possible versions could eventually reach Canada or Mexico, since GM's joint venture with China's SAIC has signaled interest in selling these Buick-badged EVs in other markets. For now, this is a look at what battery and pricing technology are producing overseas rather than something tied to any current US buying decision or incentive program. Homeowners weighing an EV purchase in the US should stick to checking what electric vehicles and rebates are actually available in their state today.
Latin America EV Sales Report: 10% EV Market Share Surpassed in Q2!
Electric vehicles passed 10 percent of new car sales across Latin America in the second quarter of this year, hitting 10.7 percent, up from 7.7 percent the prior quarter and 4.6 percent a year earlier. Sales grew 137 percent year over year, with fully electric cars (no gas engine) growing faster than plug-in hybrids, which still run on gas some of the time. Fully electric models now make up 58 percent of the region's EV sales. Brazil drove most of this growth, thanks to a domestic push to build EVs locally that has ramped up production and even started supplying neighboring countries. Brazil alone accounted for about two-thirds of the region's added EV sales and now sits at 13.5 percent EV market share. Colombia moved into second place for electric-only sales, ahead of Mexico. Uruguay leads the region in market share at over 40 percent, followed by Costa Rica near 22 percent and Colombia above 20 percent. Argentina and Paraguay lean heavily on plug-in hybrids rather than fully electric cars, while Mexico, Peru, Panama, Guatemala, and El Salvador lag behind on both sales and growth. None of this points to a specific US rebate or program, but it reflects a broader trend: electric vehicles are getting cheaper, charging networks are expanding, and more model choices are reaching buyers worldwide. For a homeowner already weighing an EV purchase alongside a home charger or solar setup, it's a sign that automakers are increasingly betting on electrification even in markets without heavy government incentives.
Wayve & Uber Can Now Deploy Robotaxis in London
This one is not about home energy upgrades, but here is the news: self-driving car company Wayve and Uber have received approval from Transport for London to run robotaxis in the city. A robotaxi is a car that drives itself, without a driver controlling it directly. For now, a trained safety driver still sits in the car and can take over if needed. Wayve builds its self-driving system into Ford Mustang Mach-E electric vehicles, using cameras and radar. The approval means the vehicles, the driver, and Uber as the operator all now hold the licenses London requires. More than 100,000 Londoners have signed up on a waiting list for a chance to try a ride once the service launches to the public. Wayve has also partnered with Nissan and Stellantis on self-driving technology and has drawn investment from Nvidia, Microsoft, Uber, and Mercedes. Uber says it now works with more than 30 self-driving companies as part of a plan to mix robotaxis and regular drivers on its app. This is a transportation and technology story, not an energy-efficiency one. It has no bearing on home heating, cooling, insulation, or rebate programs, so there is nothing here that changes plans for upgrading a house.
BYD Just Sells Cheap EVs? Check Out This $216,000 Yangwang
This is car news, not home energy news, but here's what it covers. BYD, a Chinese automaker and the world's top seller of electric vehicles (EVs), just showed off how wide its lineup really is. At the high end, its luxury brand Yangwang launched a four-seat U8L Dingcang Edition priced at about $216,000. It's a plug-in hybrid rather than a pure EV, with 143 miles of electric-only range, and it can fast-charge from 10% to 70% battery in about 5 minutes. At the other extreme, BYD's Racco is a tiny electric "kei car" built for Japan's market, priced around $13,585 before any subsidies. It picked up 700 orders in its first week, with BYD hoping for 10,000 by the end of 2026. In between, the Denza Z9S sedan starts around $47,378, offers up to 684 miles of range per charge, and can go from 10% to 70% charge in 5 minutes. It also comes with a lidar-based driver-assist system and voice-controlled features. BYD's boxy Fang Cheng Bao SUV, averaging around $32,850, just hit 500,000 units sold. None of this changes what's available to U.S. homeowners right now — these models are sold in China and Japan, not here. But it's a reminder of how fast EV technology and pricing are moving globally, including fast-charging speeds that keep shrinking and price points that span from budget to ultra-luxury.
BMW fast-tracks i3 production as strong demand sparks a major ramp-up
This is car news, not a home energy story, but here's what's happening: BMW is speeding up production of its new electric i3 sedan after seeing stronger demand than expected. The car is being built at BMW's plant in Munich, Germany, and is the second model in BMW's new "Neue Klasse" electric lineup, following the iX3, which has ramped up quickly at a factory in Hungary. The i3 uses a large 108.7 kWh battery and can charge very fast thanks to an 800-volt electrical system, adding close to 250 miles of range in about 10 minutes on a suitable fast charger. In Europe, the car has a rated range of up to 566 miles; in the US, the EPA estimate is around 440 miles for the 2027 model. In the US, the car will come with a built-in NACS charging port, the connector type Tesla popularized that other automakers have been adopting, which matters if you're thinking about home charging equipment or public fast chargers compatible with your car. Pricing in Europe starts around €65,900 (about $75,500) for the base model, with a faster launch trim closer to €75,340 ($86,400). US pricing hasn't been announced, but it's expected to start somewhere around $50,000 to $55,000 when the car goes on sale in early 2027. For homeowners thinking ahead to EV charging setups, this is mainly a signal that more long-range, fast-charging electric cars are coming to the US market next year.
Watch Tesla driver plea with police after FSD drove 64 mph in a 45
A Tesla driver in Parker, Colorado, was pulled over for going 64 mph in a 45 mph zone and told police he wasn't responsible because "Full Self-Driving" (Tesla's driver-assist software) was engaged. Police weren't swayed, saying driver-assist technology never replaces the driver and the person behind the wheel is still legally responsible, no matter what the system is called. That's correct: like other automaker systems, Tesla's FSD is what's known as a Level 2 system, meaning a human is still supposed to be driving while the software helps out. The article argues the confusion isn't really the driver's fault. Tesla markets the software as "Full Self-Driving" and has suggested drivers can do other things behind the wheel, but falls back on "the driver is always responsible" when something goes wrong. It also points out that Tesla used to let owners set a hard cap on how far over the speed limit FSD would drive, but removed that option in a recent update, replacing it with preset modes (including one literally called "Mad Max") that can push the car well past posted limits. Tesla's head of AI has reportedly said giving drivers that control back is something the company won't do. For homeowners who also drive a Tesla, this is a reminder that FSD is a driving aid, not an autonomous system, and speeding tickets or violations still fall on the driver regardless of which mode is active.
Juiced doubles down with 120-mile range e-bike on dual-battery Scrambler Hardtail
This one is about e-bikes, not home energy upgrades, but here's the gist. Juiced Bikes has released a dual-battery version of its Scrambler Hardtail, a moped-style electric bike. Adding a second battery underneath the frame brings total capacity to 1,996 Wh, giving a claimed range of up to 120 miles under ideal, low-power riding conditions. The motor and speed class are unchanged from the standard version, so the upgrade is about ride time, not top speed. The dual-battery Hardtail Scrambler is priced at $1,999, a $245 discount off its listed price, and comes with extras like fenders, a handlebar bag, bar pad, headplate, custom nameplate, and stickers. The bike keeps the same minibike-style look and 20x4-inch tires as the rest of the Scrambler lineup, but skips rear suspension for a simpler, lighter frame. If you're weighing e-bikes as part of a lower-carbon commute or errand routine, this is a data point on what's available in the long-range, budget-friendly category, priced under $2,000 with a claimed range well above typical e-bikes. It has no connection to home energy upgrades, rebates, or weatherization programs, so it doesn't affect anything on the home improvement side of things.
China Unveils Safety Standards for Autonomous Driving Systems
This one isn't about home energy upgrades, but here's what happened. China's government has set new mandatory safety rules for self-driving vehicle systems. The rules cover cars and trucks with Level 3 and Level 4 automated driving (meaning the car handles most or all driving tasks under certain conditions, though a person may still need to take over). They don't apply to automated parking features. Under the new rules, automakers have to test their self-driving systems through simulations and real-world road trials, build in safeguards over the vehicle's full lifespan, and make sure the system can monitor whether the driver is alert enough to take control if needed. The goal is to prevent misuse of the technology and make sure drivers get clear notifications about what the car is doing. China's industry ministry says this is just a first step, with plans to tighten market rules and testing methods over time. The standards take effect July 1, 2027, so nothing changes right away. This applies to vehicles sold in China, not to home energy systems or appliances, so it has no direct bearing on heating, cooling, insulation, or rebate programs for your house. If you're weighing electric vehicle purchases down the road, rules like this may eventually shape which self-driving features show up in cars sold in other markets, but that connection is still a distant one.
Hyundai launches the updated IONIQ 6 in Turkey with a sleek new look and 422 miles of range
Hyundai has redesigned its IONIQ 6 electric sedan and started selling it in Turkey and other European markets, but the update won't be coming to the United States. Hyundai has confirmed the standard IONIQ 6 is discontinued for the US market, so American buyers won't get this refreshed version. The updated car gets a smoother, more modern look with a lower drag coefficient, which helps stretch its driving range. It comes with two battery options: a smaller 63 kWh pack rated for up to 323 miles of range, and a larger 84 kWh pack rated for up to 422 miles. Both use an 800-volt electrical system that allows fast charging from 10% to 80% in about 18 minutes on a powerful enough charger. The interior also gets new tech, including a wireless phone charger and a curved dual-screen display with wireless Apple CarPlay and Android Auto. In Europe, pricing starts around 45,750 euros (about $52,700), with a sportier N-Line version starting near $67,200. For homeowners thinking about pairing an EV with home charging or solar, this news mainly matters as a sign of where EV technology is headed rather than a car you'll be able to buy here. If you're in the US and interested in this model, the news isn't all bad: Hyundai says the high-performance IONIQ 6 N variant is still on track to launch in the US by the end of 2026, even though the standard version won't return.
BYD launches 4-seat ultra-luxe flagship SUV in China for $215,000 [Images]
This news is about a car launch in China, not a home energy upgrade, so it does not connect to anything you'd plan for your own house. BYD's luxury sub-brand, Yangwang, has released a four-seat version of its U8L flagship SUV, called the Premium Edition, priced at roughly $216,000. The vehicle is a plug-in hybrid, roughly the size of a Cadillac Escalade, with four electric motors, a small gas engine, and a battery that gives it 143 miles of pure electric range and about 748 miles combined range. It also supports fast charging, going from 10% to 70% in five minutes. The SUV comes loaded with high-end features: a driver-assist system with roof-mounted sensors, a gold-accented interior, three large screens across the dashboard, massaging seats, and a drop-down entertainment screen for rear passengers. BYD plans to bring the Yangwang brand to Europe and the UK in 2027, positioning it against brands like Ferrari and Mercedes-Benz. None of this involves home electricity use, weatherization, or rebate programs, so there is nothing here that affects decisions about insulation, heating and cooling equipment, or utility incentives for your house. It is simply a look at a new ultra-luxury electric vehicle model overseas.
$20B in federal climate grants unblocked by appeals court
A federal appeals court has blocked the Trump administration from clawing back $20 billion in climate grants that Congress set up through the Inflation Reduction Act. The money, known as the Greenhouse Gas Reduction Fund, was meant to help pay for clean energy projects, affordable housing upgrades, electric vehicle manufacturing, and lower energy bills across the country. The EPA had tried to cancel the grants and take back nearly $7 billion already paid out to the nonprofit Climate United, but the U.S. Court of Appeals for the D.C. Circuit ruled the agency likely broke the law by ending the program "based solely on a policy disagreement." For homeowners, this fund is one of the sources behind various clean energy and efficiency financing programs run through local nonprofits and green banks in different states. Congress separately repealed unspent EPA funds from this program last year, so some money is still tied up, and four of the ten judges said part of the court's earlier order blocking the EPA no longer applies to that unspent portion. The EPA says it is reviewing the ruling and deciding what to do next. Nothing here changes rebates or programs you may already be using, like weatherization assistance or heat pump incentives, but it does affect whether billions in grant money keeps flowing to groups that fund clean energy and efficiency projects nationwide. If you have applied for financing tied to a state green bank or nonprofit lender, it may be worth checking whether this fund is behind it.
Trump weaponizes FCC to ban new foreign-made connected solar inverters
The Federal Communications Commission has added foreign-made "connected" power inverters to its restricted import list, starting July 28. This affects inverters that convert power between DC and AC and also have a radio for remote monitoring or control over Wi-Fi, cellular, or Bluetooth — the kind used in most modern solar and battery systems. New models that don't meet a US-content threshold can no longer be imported or sold. Despite the "foreign-made" label, this isn't strictly about Chinese products: it's based on a Buy American test requiring over 65% US content and manufacture, so a US-brand inverter assembled overseas could be restricted, while a foreign brand could qualify if enough of it is built domestically. If you already have a solar or battery system installed, this doesn't affect it. Systems on roofs and in RVs today keep working, and dealers can still sell inventory of already-approved models. The rule only blocks new, not-yet-approved connected inverters from entering the market going forward. Where this could matter down the road is if you're planning a future solar, battery, or off-grid purchase. Popular brands common in portable and off-grid setups rely heavily on overseas manufacturing, and it's unclear how quickly, if at all, they'll get approval for new models under the stricter rules. Larger US-based manufacturers with domestic factories, like Enphase, SolarEdge, and Tesla, are less exposed. In the near term, industry analysts expect the biggest impact on smaller off-grid and portable solar products rather than standard rooftop installations, where certified inventory is already stocked.
HVAC Price Increase List: August 2026
A wave of HVAC manufacturers is raising prices this August, which could mean higher costs if you're planning a furnace, air conditioner, heat pump, or related replacement soon. Most increases are in the single digits, but they vary a lot by brand and product. Legend Valve products are seeing hikes up to 25%, and Lau parts are going up 16.2-16.8% starting August 31. Several well-known equipment makers are raising prices up to 7%, effective August 3: Amana, Daikin (including ductless, VRV, and light commercial systems, plus OEM parts), and Goodman. Bard Manufacturing is raising prices an average of 6% the same day. Earlier in the month, on August 1, Amana PTAC units (a type of packaged terminal air conditioner common in some homes) and accessories go up as much as 5%, and AprilAire products rise 0-4%, depending on the item. Other companies affected include DiversiTech, Broan-NuTone, Navien, RectorSeal, and various parts and motor suppliers, with increases spread across the rest of the month through August 31. If you're weighing a heating or cooling upgrade, the timing of these increases is worth keeping in mind, since equipment ordered or installed after these effective dates may cost more than it did earlier in the year. Not every manufacturer disclosed a specific percentage, and increases differ by product line, so the actual effect on any particular system depends on which brand and model is involved.
A month after Congress killed the solar tax credit, the industry is anything but dead
The federal tax credit that covered 30% of the cost of a home solar system expired on July 4, after Congress ended the incentive as part of the One Big Beautiful Bill. Many expected the deadline to gut the home solar market. Instead, industry groups SEIA and Wood Mackenzie now project sales will drop by something like 18 to 21 percent this year, not the collapse some feared. Part of the reason may be simple: reader surveys suggest many homeowners never knew the credit existed in the first place, so its loss changes less than expected. What has changed is why people are buying. Solar shoppers are talking less about savings and more about resilience: keeping the lights on during storms and having some independence from an increasingly strained power grid. That shows up in how systems are being built. In 2025, up to 45% of new home solar installations also included a battery, up from around 6% back in 2020. Homeowners who've paired solar with batteries and, in some cases, an electric vehicle report locking in low, predictable electricity costs for years and avoiding both blackouts and gas pumps. None of this changes the fact that tax rules, state programs, and utility incentives are complicated and vary by location, so it's worth checking what your own state or utility currently offers before assuming the math has changed for your house.
The AHU Recirculating Mode Death Spiral
This is a technical story about large commercial air handling units (AHUs) — the big equipment that heats and cools office buildings, clinics, and museums, not the kind of system found in most houses. It describes a control problem engineers call the "recirculating mode death spiral," where two fans in the unit end up fighting each other during periods when the system is only recirculating indoor air rather than pulling in outside air, such as at startup, overnight setback heating or cooling, or off-hours operation. When this happens, one fan can end up at full speed and the other stuck near minimum, triggering alarms and building pressure problems. The piece is aimed at commissioning engineers and building operators who program and troubleshoot these systems, walking through a real case at a clinic where restoring a "smarter" fan control method backfired the first night it ran, tripping a safety switch, until a mix of control strategies fixed it. For homeowners, this has no direct bearing on home energy upgrades, rebates, or equipment choices for a house. It concerns the internal programming of commercial-scale ventilation equipment in large buildings, not the furnaces, heat pumps, or ducted systems typically installed in a home.
New $4.4 million municipal project tests zero upfront cost energy model for cities
The city of Cadillac, Michigan is upgrading seven municipal buildings, including city hall and the wastewater treatment plant, through a $4.4 million project that costs the city nothing upfront. Instead of paying for the work directly, Cadillac will cover it through the savings the upgrades generate over time. The deal was approved by the city council on July 20 and pairs Schneider Electric with Budderfly, a company that finances, owns, and operates energy systems under an "Energy-as-a-Service" model, similar in spirit to how some homeowners finance rooftop solar with no money down. The upgrades include solar panels, battery storage, new HVAC and lighting, EV charging, and a microgrid setup designed to keep essential services running during power outages. This is the same basic toolkit homeowners consider for their own houses, just applied at city scale to keep water treatment and emergency services running when the grid goes down. While this particular project is about city buildings, not private homes, it points to a financing approach that's spreading: paying for efficiency and resilience upgrades through the savings they produce, rather than upfront cash. Similar no-money-down or pay-as-you-save models are increasingly available to homeowners too, often through utility programs or state energy offices. If you're weighing an upgrade like a heat pump, solar, or battery storage but are wary of the initial cost, it's worth checking whether your state or utility offers a financing option that works the same way, letting the savings pay off the investment over time.
PJM’s big new data center plan: Make the states figure it out
The regional grid operator PJM, which manages power supply across 13 states from Illinois to Virginia, has proposed a plan to keep massive data centers from driving up everyone else's electric bills. Data centers use huge amounts of power, and PJM expects them to add 30 to 34 gigawatts of demand by the early 2030s. Building enough power plants to meet that growth would otherwise get passed on to regular utility customers. Under the new plan, PJM would require large power users — data centers of at least 50 megawatts — to either line up their own power supply (new solar, wind, batteries, or backup generation) or risk being cut off from the grid first during emergencies, starting in 2027. But PJM can't tell individual utilities which customers to cut off — that's a state decision. So the plan leans on states and utilities to actually enforce this, through tools like "large load tariffs" that tie a data center's costs to its own grid impact. Some states, including Illinois, are considering laws requiring data centers to pay for clean power to match what they use. Consumer advocates say most states aren't ready to put these rules in place yet. The plan still needs approval from federal regulators. For homeowners, the bigger picture is this: rising electricity prices in this region have been tied partly to data center growth, and how well your state follows through on these rules could affect whether that cost pressure eases or continues to show up on your utility bill.
"Invest for Impact": Why Greenbuild matters more than ever
This is industry news about a trade conference, not a program that directly affects your home or wallet. The U.S. Green Building Council's Greenbuild International Conference and Expo is coming to New York City for the first time, running Oct. 20–23 at the Javits Center, with the theme "Invest for Impact." The event brings together architects, developers, building owners, investors and policymakers to discuss trends like decarbonization, energy efficiency, resilience and the fast-growing demand for data centers driven by artificial intelligence. For homeowners, the relevance is indirect. The conference will offer early looks at the next version of LEED, the green building rating system used mainly for commercial and large residential projects, along with sessions on topics like embodied carbon (the emissions created in making building materials), grid-interactive buildings, and healthy materials. These are the kinds of standards and technologies that eventually filter down into building codes, products and rebate programs, but nothing announced here changes what's available to homeowners right now. In short, this is a heads-up that the building industry is shifting how it talks about sustainability, framing it as a financial investment rather than a separate goal. It's worth knowing this conversation is happening, since ideas discussed here often shape future codes and incentive programs, but there's no direct action or new homeowner rebate tied to this event itself.
California DER wholesale market participation could grow 2+ GW from CAISO ‘accounting change’: advocate
California's grid operator, CAISO, is proposing a change that could open up more value for home battery owners in the state. Right now, if you have a battery paired with solar and it sends extra power back to the grid beyond just covering your own home's use, that extra power typically only earns retail credit through net metering, not the higher payments available in wholesale electricity markets. A draft proposal released last month would let aggregated home batteries earn wholesale-level value for helping reduce electricity demand across any of California's 20-plus grid sub-regions, rather than being limited to offsetting only their own building's load. An industry advocate estimates this shift could bring more than 2 gigawatts of home batteries and other behind-the-meter devices into California's wholesale power market. CAISO is expected to release a revised version of this framework around August 19. A related, separate process at the California Public Utilities Commission could further expand how home batteries and similar devices get paid, but that timeline is murkier — a final decision there may not come until sometime in 2027 or even as late as February 2028. For homeowners in California with battery storage, or considering it, this is a sign that the financial case for batteries may improve over time, though nothing has changed yet in terms of what your utility or battery program pays today.
Base Power raises $1B to get big batteries into more homes
Base Power, a company that installs home batteries, just raised $1 billion, pushing its valuation to $13 billion. Instead of asking homeowners to buy a battery outright, which can cost more than $10,000, the company installs its own batteries for an upfront fee of $95 to $695 (the amount depends on location) plus an ongoing electricity subscription. In return, Base Power taps those batteries to send power back to the grid when demand is high, which is how it makes money. For homeowners, the appeal is backup power when the grid goes down and cheaper electricity on normal days, without the big upfront cost of buying a system. The company has installed batteries at 17,000 homes so far, mostly in Texas and now also in Illinois. It's opened its own manufacturing line in Austin, Texas, replacing overseas suppliers, and plans to start using domestic battery cells by the end of the year. Its newest model, called Base Core, is more powerful than typical home batteries like the Tesla Powerwall — it can deliver 20 kilowatts of power at once and store nearly 40 kilowatt-hours, versus 5 kilowatts and 14 kilowatt-hours for a Powerwall. Customers can add more than one unit for even more storage. The new funding will go toward hiring more installers and speeding up installations. Base Power currently operates under Texas's and Illinois's market rules, but it also partners directly with utilities in other states, meaning the model could eventually expand beyond those two states, though nothing has been confirmed elsewhere yet.
Aurora Solar launches online marketplace to provide home solar estimates
A company called Aurora Solar, whose design software is already used by many solar installers, has launched an online tool for homeowners to get rough estimates on rooftop solar. You enter your address and average electricity bill, and it shows an estimated system size in kilowatts, battery storage size in kilowatt-hours, cost per watt, and projected savings and payback time. In some areas, it also shows estimated monthly payments if you financed the system with a solar loan or a power-purchase agreement, where you pay for the electricity a company's panels produce rather than owning the system outright. You can adjust the system size to see how costs and savings change, and chat with an AI assistant or call for live help. Aurora says these are non-binding estimates that an installer would confirm with an actual visit to your home. The tool is available at quote.aurorasolar.com and joins other online solar quote sites like EnergySage, Electrum, and SolarReviews. Coverage varies by location — some areas show quotes from several competing installers, others show few or none. The launch comes as solar companies look for ways to cut costs after the federal 25D solar tax credit ended at the end of 2025. Industry data cited alongside the announcement shows that labor, overhead, and customer acquisition — the cost of finding and signing up customers — make up a large share of a typical solar installation's price, so tools like this are partly aimed at lowering that cost by connecting homeowners and installers more directly.
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.
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.
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.
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.
