Maryland signs agreement for power produced on reclaimed coal mine
Maryland has signed a 20-year deal to buy solar power from a large project being built on a closed coal mine in the western part of the state. The state expects the agreement to save around $300 million over two decades, with estimates ranging from $298 million to $515 million depending on how electricity markets move. Starting in 2028, the state will buy about half the output of the 300 MW Jade Meadow III Solar Project, enough electricity to power more than 20,000 homes a year, making up close to 15% of the state's overall power portfolio. The project sits on nearly 6,000 acres of former mining land, with about 1,850 acres used for construction. It's currently being built and is expected to start operating in the second half of 2027, with the state's purchases beginning the following year. The developer, REV Renewables, says it's investing more than $500 million and expects to employ over 1,200 people at the peak of construction. This deal doesn't change anything for individual homeowners directly — it's a purchase between the state and a power developer for electricity used in state buildings and operations. But it does add a large chunk of solar power to Maryland's grid and supports the state's climate goals, which call for cutting greenhouse gas emissions 60% by 2031 and reaching carbon neutrality by 2045. It also builds on other state renewable energy contracts already in place, including solar and wind projects at Mount St. Mary's and the Roth Rock and Pinnacle wind farms.
What PG&E has learned in two years of flexible interconnection
Pacific Gas and Electric has spent two years running a program called Flex Connect, which lets large electricity users connect to the grid faster if they agree to cut back power use during peak hours. Instead of waiting for full grid upgrades to get a standard ("firm") connection, participants get a guaranteed baseline amount of power plus extra capacity when the grid has room. PG&E says sites on this program actually had access to extra power above their baseline 90% of the time over the two years. The program has grown more slowly than PG&E hoped — it aimed for 10 sites online by the end of 2025 but reached only five — though the utility says its waiting list has expanded to about 85 sites being evaluated, many from repeat customers. Most of these are electric vehicle charging stations, since chargers are a natural fit for flexible power limits, but PG&E is also seeing rising interest from data centers and manufacturing facilities. The first flexible data center project, sized at about five megawatts, is set to come online this fall in the Bay Area. None of this involves a program homeowners can sign up for directly — it applies to large commercial and industrial customers, not residential upgrades. But it points to how utilities like PG&E are trying to speed up grid connections generally, including for equipment that draws a lot of power, which could shape how quickly the grid can support things like EV charging infrastructure in your area over time.
Lexington-Fayette County Solar Zoning Amendment Critical to Achieving Climate Goals and Lowering Costs
Lexington's local council is set to consider a zoning change that would open up to one percent of Fayette County, Kentucky, including farmland, for large-scale solar projects. Any solar built under the new rule would have to be "agrivoltaic," meaning the land keeps working as a farm — through grazing or pollinator habitat, for example — while also hosting solar panels. Supporters say this lets farmers keep an income from their land while adding a new one from leasing space for solar. This is local policy news rather than something that changes your own options right away. It does not create a rebate or program for homeowners to sign up for. But it matters for the area's power supply: backers say solar built on that one percent of county land could generate as much electricity as more than 30,000 rooftop solar installations, at a time when over 90 percent of Kentucky's power still comes from fossil fuels. The change is tied to Lexington's "Race to Net Zero" plan, a city goal to cut emissions to net-zero by 2050. If the zoning change passes, it could mean more solar-generated power reaching the local grid over time, which in turn could affect electricity costs and availability in the area — though the article does not spell out timelines or specific project plans. For now, this is a vote to watch rather than a program to apply for.
Center for Rural Affairs publishes guide for renewable energy land leasing
The Center for Rural Affairs has put out a free fact sheet to help farmers and other landowners think through leasing their land to wind or solar developers. It walks through the whole process, from the first conversation with a developer, through site evaluation, lease negotiation, construction, operation, and eventually taking the equipment down when the project ends. The group notes that lower-producing farmland can be a good fit for these projects, since it can bring in steady payments for years from acres that aren't great for farming anyway. Some projects also use "dual-use" setups that let the land keep working for agriculture alongside the energy equipment, through grazing animals, growing crops between panels, or beekeeping. Before signing anything, whether it's an early lease option, a notice of intent, or a full long-term agreement, the guide encourages landowners to ask questions, get professional advice, and lean on outside organizations for support. A solid lease, the group says, should spell out not just how the project starts but how the land gets used, maintained, and restored once the project is over. This isn't tied to a specific state or deadline, and it doesn't apply to typical home energy upgrades like insulation or heat pumps. It's aimed at people who own farmland or larger rural properties and are weighing an offer, or thinking about approaching a developer, to host a wind or solar project on their land.
The cheapest new cars to own in America are THESE retro-styled EVs
A new study of 50 new cars found the Fiat 500e, a small electric car, is the cheapest to own and run in America, at $3,557 a year. That covers energy costs, maintenance, insurance, and fees and taxes combined. The next cheapest is the Honda Civic Hybrid at $4,833 a year, followed by gas models like the Hyundai Elantra and Nissan Versa. The surprise is second place among electric vehicles: the Dodge Charger Daytona, a retro-styled EV, costs $5,298 a year to own, beating the Tesla Model 3 and Hyundai Ioniq 6 by roughly $200 each, and coming in about $200 cheaper than a Honda Accord. Across all 50 vehicles studied, the average annual cost was $6,913, up $451 from a similar study two years ago. Hybrids as a group were the cheapest to own overall, at $5,734 a year on average, compared with $6,189 for electric vehicles and $7,025 for gas-only cars. At the other end, the Porsche 911 and Audi RS7 topped $10,000 a year, and the Lucid Air was the priciest electric vehicle to own, at $10,049 annually. For anyone weighing a new car purchase alongside home energy upgrades, the takeaway is that sticker price doesn't tell the whole story. Fuel or electricity costs, insurance, maintenance, and taxes all add up differently depending on the vehicle, and a cheap-to-buy EV or hybrid can end up saving real money each year compared with a pricier gas car.
LONGi energy strategy is not just “one plus one”
LONGi, one of the world's largest solar panel makers, is expanding into battery storage. The company's new strategy, called LONGi ONE, bundles solar panels with batteries and the software that manages them, rather than selling panels alone. The idea is that solar power increasingly needs batteries to store electricity generated during the day for use later, especially as more solar on the grid has led to periods of very cheap or even negative-priced electricity in some places. This is mainly industry and business news rather than something that changes what's available to homeowners right now. LONGi's push includes a plan to set up 30 regional service centers by 2028 to support battery maintenance and technical help, and it recently acquired a company called PotisEdge to gain battery-management technology. The company describes its goal as helping customers decide when to charge and discharge batteries and how to earn revenue from selling stored power back to the grid at the right times. For homeowners, the practical takeaway is that major solar manufacturers are betting heavily on pairing rooftop or utility solar with battery storage as the next phase of the industry, rather than treating panels as a stand-alone product. If you're considering solar for your own home, this points to batteries playing a bigger role going forward, both for backup power and for managing electricity costs. Specific rebates or programs for home battery systems vary by state, so it's worth checking what's offered where you live.
Investing in the Next Generation Through Scholarships
The Building Performance Association, a trade group for the home energy efficiency industry, has been offering scholarships to help newcomers attend its conferences. These events cover topics like home energy audits, insulation, and heat pumps, and bring together new workers, business owners, and experienced professionals in the field. Through the Mike Rogers Memorial Scholarship Fund, the group has awarded over $117,000 to more than 215 people so far, covering conference costs for those who couldn't otherwise afford to attend. This news is mostly about the industry itself rather than something that changes how you'd plan a home upgrade. But it's a sign of how the field that installs and inspects energy improvements — audits, insulation, heat pumps — is training its workforce. A more experienced, better-connected pool of energy auditors and contractors can mean more knowledgeable help when you're ready to look into upgrades or rebates for your own house. The group is currently accepting scholarship applications for its upcoming Alaska Home Performance Conference & Trade Show, with this being the last week to apply. This is aimed at people entering or working in the industry, not homeowners directly, but it's worth knowing the field is actively bringing in new talent as demand for home energy upgrades grows.
I tested this lithium-ion battery charging cabinet as the safest place to charge your e-bike batteries
If you charge e-bike or power tool batteries at home, a new type of storage cabinet is meant to make that safer. The Yolin lithium-ion battery charging cabinet looks like an ordinary steel shop cabinet but is built specifically for charging lithium batteries. Inside, it has built-in outlets for multiple chargers, a temperature-controlled fan that switches on only when needed, and its own smoke alarm so you would know quickly if something went wrong while you were in another room. The main safety feature is automatic fire suppression built into the cabinet, designed to trigger if it senses the extreme heat of a battery fire (called thermal runaway). Combined with double-wall steel construction, the goal is to contain a fire rather than let it spread through a garage or home. The maker says the design references European fire-resistance standards and is meant to hold up for up to 90 minutes. Yolin sells two sizes: a smaller "Urban" cabinet for $599, good for charging one or two batteries in an apartment or garage, and a larger "Workshop" model for $899 with more shelving and six outlets, aimed at people with several e-bikes, tools, or a small fleet of batteries. Both take up the same floor space, so the choice comes down to how much charging capacity you need. For someone with a single e-bike charged occasionally, normal charging habits are probably enough. For a household with multiple bikes or battery-powered tools, a cabinet like this offers an extra layer of protection, at a real cost.
33 HVAC Contractors Make the 2026 Inc. 5000 List
Inc. Magazine has released its 2026 Inc. 5000 list, an annual ranking of the fastest-growing private companies in the U.S. This year, 33 HVAC (heating, ventilation, and air conditioning) contractors made the list, along with several companies that support the industry, such as marketing firms, a warranty provider, and a maker of HVAC chemicals and products. To qualify for the list, companies had to be privately held, for-profit, based in the U.S., and not owned by another company. They also needed at least $100,000 in revenue in 2022 and at least $2 million in 2025. Growth is measured as the percentage increase in revenue over that three-year period, and this year's honorees had a median growth rate of 130 percent. Among the non-contractor companies recognized were marketing firms Rival Digital and Red Barn Media Group, warranty provider JB Warranties, and Refrigeration Technologies, a supplier of HVAC chemicals making its fifth consecutive appearance on the list. For a homeowner, this news is mostly a snapshot of which HVAC companies are expanding quickly, not something that changes your options for upgrades or rebates directly. It can be useful background if you're researching contractors and want to know which ones are growing fast and gaining recognition in the industry, but it doesn't affect what you're eligible for or when.
Thornova Solar to make silicon cells in Oklahoma under Nextnova name
A new solar cell factory is coming to Yukon, Oklahoma, just outside Oklahoma City. The company behind it, Nextnova, is a new brand from Thornova Solar, which has been supplying solar panels to the U.S. since 2022. Thornova itself started as the U.S.-focused arm of China's Sunova Solar, and it also runs production in Kenya and has manufacturing access in Indonesia. The Oklahoma plant will take over a 450,000-square-foot building once used by Xerox. It's set to start mass production of p-type silicon solar cells (a common, well-established solar cell technology) in early 2027, with capacity to make 2 gigawatts worth of cells a year, expandable later to 6 gigawatts. The project is expected to create 300 jobs. For homeowners, this is mainly a sign of more solar manufacturing moving to U.S. soil, which can matter for panels that need to meet "made in America" requirements tied to certain tax credits or rebates. It's not yet clear where Nextnova's cells will end up being turned into finished solar panels or where those panels will be sold, so there's no direct word yet on whether this changes what's available to homeowners shopping for solar. Worth keeping an eye on if you're considering solar and care about where your equipment is made, but no immediate action or availability to note yet.
Hydrogen Is Still A Tonnes Market, No Matter How Many MWh We Assign To It
This is a story about how hydrogen gets counted, not about a new product or rebate you can use at home. Global hydrogen demand topped 100 million tonnes in 2025, and almost all of it goes to refining and industrial uses like fertilizer and chemical plants, not homes. Some analysts and exchanges have started converting hydrogen into megawatt-hours (MWh), the unit used for electricity, so it can be compared side by side with power and gas prices. The piece argues that's a framing choice, not a sign that hydrogen is actually competing to heat homes or run appliances the way electricity does. The distinction matters for anyone weighing whether hydrogen heating or hydrogen-fueled equipment might show up as an option for their house. Converting hydrogen's chemical energy into MWh can make it look like an interchangeable alternative to electricity or natural gas on a price chart, but in practice, hydrogen used for space heating still has to compete on real-world cost, efficiency, and infrastructure — and right now, it barely factors into residential heating at all. For homeowners, the practical takeaway is that heat pumps, electric heating, and other technologies already sold and installed in homes remain the near-term options, while hydrogen for heating is still speculative and mostly discussed in industry and policy circles rather than something being installed in houses. There's no new rebate, product, or deadline here — just a reminder that hydrogen's future in home heating is still unproven.
EcoFlow Labor Day power station sale with up to 58% savings, Aventon Aventure 3 e-bike $1,799, Anker SOLIX bundle, more
This is a roundup of Labor Day sales on portable power gear, not a policy or rebate update, so there's not much here that ties directly to home energy upgrades. Still, a few items could interest homeowners looking at backup power options. EcoFlow has launched a Labor Day sale on power stations (battery packs that can run appliances during an outage or off-grid), with discounts up to 58 percent and prices starting at $169, running through the rest of August. Separately, Anker is offering its SOLIX C300X, a 288Wh portable power station bundled with a 60W solar panel, for $300, but that deal is one day only. Jackery also has deals included in the roundup, though specifics aren't given. The rest of the sale covers e-bikes and yard equipment rather than home energy systems: Aventon's Aventure 3 e-bike is down to $1,799 as part of its own Labor Day event, Heybike has an early-bird price on its Titan full-suspension e-bike starting at $1,399, and Segway has ongoing e-scooter and e-bike deals from $280. On the yard-tool side, Greenworks is selling its Pro 80V 10-inch cordless electric cultivator for $290. None of this is tied to any utility rebate or government program — it's retail pricing on consumer gear. If you're shopping for a small backup power station for outages, the EcoFlow and Anker deals are worth a look before the sales end, but they don't affect eligibility for any home energy-efficiency incentives.
Crawl Space/Slab insulation assembly questions
A homeowner building a new house in southeast British Columbia switched from a slab-on-grade foundation to a crawl space after digging revealed conditions the foundation contractor and engineer didn't expect. The site sits near a river with flood risk, so groundwater is a real concern, and the homeowner turned to an online forum for advice on insulating the new foundation. A building science expert weighed in with specific guidance. For under-slab insulation, he recommended R-10, typically achieved with 2 inches of XPS (extruded polystyrene) foam board, noting that going much thicker offers little added benefit since ground temperature swings less the deeper you go. He also said XPS holds up better than EPS (expanded polystyrene) when buried in soil, citing an Alaska Department of Transportation study, though newer XPS formulas have addressed the environmental concerns that once set the two materials apart. On the walls, the home uses 11-inch ICF (insulated concrete form) blocks with a 6-inch foam core, already providing better insulation than many building codes require even in cold climates. The expert suggested skipping additional batt insulation inside the ICF wall and instead attaching rigid polyiso foam directly to the interior surface for a bigger efficiency boost in less space. Local flood-mitigation rules bar a full basement here, since mechanical equipment must sit above a set elevation, which shaped the decision to build a crawl space instead.
Data centers’ hidden water footprint is linked to the grid
Data centers get attention for the water used to cool servers on-site, but a bigger piece of their water footprint is hidden in the power plants that supply their electricity. Nuclear and coal plants use large amounts of water for cooling, while gas plants use less and wind and solar use almost none. A new analysis by the sustainable investment group Ceres estimates that data centers in seven states — Arizona, California, Georgia, Illinois, Ohio, Texas, and Virginia — used about 3.4 trillion gallons of freshwater in 2024 through their electricity use, roughly 12 times what Los Angeles, Phoenix, and Washington, D.C. use combined. That figure could reach 4 to 8 trillion gallons by 2030. About two-thirds of the power plants studied sit in areas already facing water stress, including Arizona, which is in a long-term drought, and Illinois, which relies on nuclear plants in water-stressed parts of the Mississippi-Missouri river basin. Only Meta reports this indirect water use publicly, and its number was more than 20 times higher than the water used directly at its data centers in 2024. Amazon, Google, and Microsoft don't disclose comparable figures, though Amazon says it tracks the data. All four companies have pledged to become "water positive," replenishing more water than they consume, and point out that agriculture and lawn watering use far more water nationally. For homeowners, this doesn't affect your utility bill or rebates directly, but it's a reminder that growing data center electricity demand can strain water supplies in the same regions many people live in, especially in already drought-prone states.
Solar delivers as Europe’s power plants struggle amid heat and drought
This summer's record heat and drought in Europe put a strain on the power plants that keep the lights and air conditioners running. Nuclear, gas, and coal plants had to cut output because rivers used for cooling grew too warm or dried up, and low wind during the heat waves cut wind power too. France lost 18% of its nuclear capacity in mid-July for these reasons, and UK gas plants scaled back as well. Solar panels were the one power source that performed better than usual, producing 17% more electricity during the heat waves, according to the energy think tank Ember. Paired with batteries, which store solar power to use after sunset, this kept air conditioners running into the evening when heat lingered but the sun had gone down. Electricity demand jumped sharply during the heat waves — up 28% in Italy and 14% in France compared with the week before — and prices spiked at times to levels not seen since the 2022–23 energy crisis. None of this changes rebates or programs available to homeowners, but it's a real-world example of solar and battery storage proving useful during extreme heat, when the power grid is under the most strain. As heat waves become more common and more households add cooling systems, industry analysts say growing battery storage will matter for keeping power reliable and prices in check during future hot spells.
Ford has a new $25,000 crossover SUV coming, but will it go electric?
Ford is planning a new crossover SUV priced around $25,000, expected to arrive in 2029. Dealers got a preview of the vehicle at a private meeting, describing it as a boxy, wide SUV similar in look to the first-generation Escape. It would become Ford's cheapest model, priced below the current Maverick, and is expected to eventually replace the Escape. Production is set for Ford's Hermosillo plant in Mexico. Despite the low price, this SUV will not be electric. Instead, Ford plans to offer it as a hybrid (a gas-electric combination) or a standard gas-powered vehicle. That's notable because Ford's other upcoming affordable vehicle, an electric pickup called the Fathom, does use the company's new all-electric platform. Ford executives reportedly told dealers the company remains committed to hybrid powertrains going forward. For homeowners tracking electric vehicle options, this means Ford's cheapest SUV won't be a plug-in choice, at least for now. The Fathom pickup remains Ford's affordable EV entry, with pre-orders opening in early 2027 at a starting price of $28,350 and deliveries later that year. Ford has said its electric vehicle platform could eventually support smaller vehicles, so an affordable electric SUV from Ford isn't ruled out, but nothing is confirmed. If you're weighing an EV purchase tied to home charging or electricity upgrades, this news suggests waiting for more details rather than expecting a budget electric SUV from Ford soon.
Burns & McDonnell partners with Gritt on robotic solar installation aids
Two companies, engineering firm Burns & McDonnell and robotics startup Gritt, have teamed up to test AI-powered robots on large, utility-scale solar farms — the kind of big power-plant installations that supply the electric grid, not rooftop systems. Gritt makes attachments for standard construction equipment that can handle repetitive, physically demanding jobs like lifting and placing solar panels, pouring concrete and laying rebar. Over the past year the two companies have already tested the technology at several solar construction sites. The goal is to make large solar projects safer and more predictable to build, since workers currently lift 80-pound panels repeatedly during installation. Unlike robots built for factory floors, Gritt's systems are designed to work outdoors in varying terrain and weather, and they're meant to work alongside human crews rather than replace them. This is part of a broader trend of automation showing up in solar construction, with other companies also building robotic installation aids for big solar farms. None of this involves home solar installation — it's aimed at the utility-scale projects that feed power into the grid. For a homeowner, the practical effect, if any, would be indirect: faster, cheaper construction of large solar farms could eventually influence electricity supply and costs in your area, but there's no rebate, product or program here that applies directly to your house.
3 Ways Scientists Can Help Hold Major Polluters Accountable Under the Trump Administration
A new study adds to evidence tying specific fossil fuel companies to real-world harm. Researchers found that nearly half of the climate-driven changes to snowpack, streamflow, and irrigation water in the western US between 2014 and 2024 can be traced to emissions from 122 of the largest fossil fuel producers and cement makers, including ExxonMobil, Chevron, BP, and Shell. This comes as the West faces mounting strain: an extreme heatwave this past March melted snowpack early across the region, three of five major river basins recorded their lowest snowpack ever measured on April 1, and Lake Mead, which supplies water to more than 25 million people, hit a new record low. This kind of research, called source attribution science, is being used to support lawsuits and legislation aimed at holding major polluters accountable, alongside historical evidence that fossil fuel companies knew about climate risks from their own internal research decades ago. At the same time, scientists and their findings have faced growing political pressure, including efforts to discredit climate research and limit what information reaches courts. For homeowners, this isn't a program or rebate update, but it does explain part of the backdrop behind worsening drought and water pressures in western states. Separately, fossil fuel companies are pushing state and federal legislation, including a bill from Rep. Harriet Hageman and Sen. Ted Cruz, that would grant them immunity from these kinds of climate lawsuits. Utah, Tennessee, and Oklahoma have already passed similar state-level liability protections.
Nature takes its place in SBTi’s net zero standard
This is a corporate climate policy story, not something that touches your house directly. It's about a new standard from the Science Based Targets initiative, a group that sets rules for how companies plan to reach "net zero" (cutting climate pollution to as close to none as possible, then offsetting what's left). The update spells out how big companies can count investments in forests, wetlands, and other natural carbon sinks toward their climate goals, alongside things like planting or restoring land and paying for engineered carbon removal. The rules say companies must keep cutting their own emissions first, but starting now they can also take voluntary responsibility for emissions they haven't eliminated yet, by supporting verified projects that protect or restore nature. That responsibility becomes required in 2035, when companies must cover at least 1 percent of remaining emissions with removals, rising over time toward 100 percent by their net-zero date, and no later than 2050. Some of these removals must come from methods that store carbon for a very long time, though the standard leaves open exactly how nature-based projects fit into that long-term category, with more guidance expected before 2035. None of this changes home energy programs, rebates, or upgrade costs. It's a signal about how large corporations plan to account for and fund climate action in coming decades, including possible growth in nature restoration projects.
Homes In London Are Cracking As The Clay They Are Built On Shrinks
Homes across much of London sit on clay soil, which shrinks when it dries out and swells when wet. After five heatwaves this summer, that shrinking is pulling foundations apart, causing what's called subsidence — the slow sinking or settling of the ground under a building. Residents describe cracked walls, sticking doors, and shifted kitchens. Older Victorian and Edwardian houses, built with shallow foundations directly on the clay, are most at risk. Modern buildings with deeper foundations are largely spared. The cost is adding up fast. UK insurance claims for subsidence hit a record in the second quarter of this year, averaging £20,000 (about $27,200) per household, up 15 percent from a year earlier. Payouts have jumped roughly 90 percent over four years, reaching £297 million. Fixing subsidence damage, through a process called underpinning that reinforces a building's foundation, can cost £20,000 to more than £100,000, and the damage itself can cut a home's value by up to 25 percent. Insurers, wary of unpredictable payouts, tend to respond to rising claims by excluding coverage or raising premiums. The risk isn't confined to today's cracks. UK government researchers estimate 1.8 million properties, about 5 percent of the country's buildings, are likely to face this kind of shrink-and-swell subsidence by 2070, a figure that could rise to 4.2 million under more severe warming. The areas most exposed are dense parts of London, Kent, and southeast England.
Sierra Club Condemns Trump-Appointed TVA Approval of Massive Illinois Coal Mining Expansion
The Tennessee Valley Authority's board voted to sell its federally owned mineral rights to the Sugar Camp mine in Illinois, a decision that clears the way for one of the nation's largest coal mines to keep operating. The Sierra Club says the move could allow up to 30 more years of underground mining at the site using a method called longwall mining, which extracts coal in long strips and can cause the ground above to sink. The mine's operator, Foresight, has a troubled record. Four of its managers were recently indicted on federal charges tied to concealing an underground fire that put miners at risk, and Illinois' attorney general is suing over illegal discharges of PFAS, chemicals used to fight that fire, into local waterways. Environmental groups had sued in December to try to block the TVA from expanding coal mining in the state, citing the operator's history of safety violations and miner deaths, but the board proceeded with the sale anyway. This is a policy and industry story rather than something requiring homeowner action. It does not change any rebate program, tax credit, or upgrade option available to you. It does reflect a broader push by the current administration to support coal production, including rolling back some environmental and worker-safety rules, which is worth knowing if you're tracking the direction of national energy policy. If you're in Illinois or near the Tennessee Valley Authority's service area, this is the kind of decision that shapes the region's electricity mix over the long run, even though it has no immediate effect on your home's utility bill or upgrade choices.
When Do You Trade In Your EV For A New One?
This is a personal story, not policy news, but it touches on something homeowners with electric vehicles (EVs) may wonder about: how long an EV actually lasts before it makes sense to trade it in. Several longtime EV owners share their experiences. One couple's Tesla Model 3 has run about 112,000 miles over seven years and lost roughly 10 percent of its battery range, which they call minor and manageable. A rideshare driver they know plans to keep driving his Model 3 until it hits 700,000 kilometers. The consensus is that EV batteries hold up far better than early adopters feared, and that EVs generally need less mechanical repair than gas cars, since there is no timing belt, gearbox, or water pump to wear out. The reasons people actually traded in their EVs had little to do with the battery. One owner upgraded mainly because getting in and out of a sedan had become harder with age, and a taller model was easier. Another cited wanting more cargo space, higher ground clearance, and easier rear-seat access for older passengers. A third owner simply likes trading every couple of years to avoid steep depreciation and wanted newer comfort features. For a homeowner with an EV in the garage, the takeaway is reassurance rather than a warning: battery wear at high mileage is usually modest, and most trade-in decisions here were about comfort, convenience, or preference rather than the car breaking down.
Future EVs could get more range from this tiny TI sensor
Texas Instruments has built a new sensor aimed at making electric vehicles more efficient. It's designed to sit inside the "traction inverter," the part of an EV that controls how power flows from the battery to the motor. The sensor measures electric current very precisely, which lets the car deliver power to the motor more smoothly. Current sensors force a tradeoff: ones with a magnetic core are accurate but bulky, while smaller, coreless sensors can lose accuracy when they shift slightly due to vibration while driving. TI's new sensor, called the TMCS2100-Q1, measures the magnetic field in two directions at once instead of one, which lets it correct for that vibration. TI says this makes it about 20 times more accurate than existing coreless sensors, even when it shifts position by less than half a millimeter. For someone driving an EV, the potential payoff is smoother acceleration, a quieter motor, and better efficiency, which could mean more range from the same battery. Because the sensor is small, automakers could also use it to build lighter, more compact inverters. This is one component among many, though, so it won't translate into a guaranteed number of extra miles, and how much difference it makes will depend on how each automaker designs the rest of the vehicle. It's an early-stage development in components that go into future EVs, not a feature you'd see in a car on the lot today.
The tangible intangibles of sustainability events
This piece is about the sustainability conference and events industry, not home energy upgrades, so there's nothing here that affects a homeowner's plans, budget, or rebate decisions. The discussion centers on why professionals keep attending sustainability conferences despite the costs in money, time, and travel. It points to a report finding that attendees value peer connections and informal networking more than scheduled talks and panels. It also notes that the conference calendar has shifted, with events once spread across many separate gatherings now concentrated into shorter periods like COP summits and Climate Weeks, while also spreading to more countries, including growth of programming in India, Asia, Latin America, and parts of Africa. This year's UN COP31 summit is scheduled for Antalya, Turkey, in November. None of this touches on specific home energy technologies, rebate programs, deadlines, or dollar amounts a homeowner could use. It is industry commentary aimed at people who plan or attend professional sustainability events, discussing the value of in-person networking versus formal programming. There is no new policy, incentive, or technology announcement here that would change what a homeowner might do about insulation, heat pumps, air sealing, or similar upgrades to their own house.
Tesla to inaugurate new Semi factory in Nevada next month
Tesla plans a grand opening next month for its new Semi truck factory in Sparks, Nevada, though the plant has already been building trucks for months. The company says the September 24 event marks the official inauguration, even though the first truck rolled off the high-volume line back in April. The factory sits next to Tesla's existing Gigafactory Nevada and is designed to eventually build up to 50,000 electric semi trucks a year, though analysts expect Tesla to deliver far fewer than that in 2026 as production ramps up slowly. This news mostly concerns commercial trucking rather than home energy use, so it won't directly affect homeowners planning upgrades. But the trucks themselves are notable: Tesla is building two versions, one rated for 325 miles of range and a longer-range model rated for 500 miles, both using a powerful electric motor setup. They can also fast-charge using Tesla's charging network, restoring about 70% of range in roughly 30 minutes, similar in spirit to home EV charging but on a much larger scale. For homeowners, the practical takeaway is limited — this is about industrial-scale electric trucks, not home electrification, solar, or rebate programs. It's a sign that heavy-duty electric vehicles are edging closer to real-world availability, which over time could affect things like delivery trucks and local freight, but there's nothing here that changes what's available for home energy upgrades right now.
Making This Fossil Fuel Crisis Europe’s Last One
More than 100 organizations and businesses have sent a letter to European Commission President Ursula von der Leyen, asking her to commission an independent, science-based plan to end Europe's reliance on fossil fuels for good. The letter argues that this summer's fuel price spike has cost European households and businesses more than €50 billion in extra energy costs, on top of a deadly wave of heat, wildfires, and drought that the letter says killed at least 14,000 people in Europe during a June heatwave alone. The groups want the requested report to lay out a full accounting of what fossil fuel dependence costs households, industry, and governments each year, then chart the fastest realistic path off fossil fuels using renewables, energy efficiency upgrades, better grids, and recycling-based industry, rather than unproven technologies. They also want the plan to redirect government subsidies away from fossil fuels, protect lower-income households and workers during the shift, and invest more in natural approaches like forests, wetlands, and green spaces that absorb carbon and cool cities cheaply. This is a European policy push, not a program homeowners can apply to. There's no funding, rebate, or deadline here for individual households. But it signals that European leaders are under pressure to move faster on the kind of home energy efficiency and clean-power investments that, over time, tend to translate into rebate programs and incentives at the national level. Homeowners in EU countries may see more movement on this front depending on how their own government responds.
Dubai VDX becomes world’s first purpose-built eVTOL vertiport
This is aviation news, not a home energy story, but here is what happened: Dubai has certified what developers call the world's first purpose-built vertiport for eVTOLs — small, battery-powered aircraft that take off and land straight up, without a runway. The facility, called VDX, was built by Skyports Infrastructure and just received certification from the UAE's General Civil Aviation Authority, clearing the way for commercial air taxi flights to begin. The site has two landing pads and fast DC charging so the electric aircraft can recharge quickly between flights. At about 33,500 square feet, it's designed to handle up to 170,000 passengers a year and will serve as the main hub in Dubai's planned air taxi network, which includes three more vertiports now under development. The project is a partnership between Skyports and Dubai's Roads and Transport Authority. None of this affects home energy upgrades or rebates. It's a look at how electric aviation infrastructure is developing in Dubai, aimed at short urban trips by air taxi rather than anything homeowners would use or benefit from directly.
Mercedes CEO on his fake-V8 electric AMG: ‘like a born-again Christian’
This is car industry news, not directly about home energy upgrades, but it touches on EVs, which matter to homeowners thinking about charging at home. Mercedes CEO Ola Källenius said driving the electric AMG CLA 45 made him feel "like a born-again Christian," praising its simulated V8 engine sound, including fake pops, bangs, and virtual gearshift feedback. He argued that the things enthusiasts love about gas engines haven't disappeared with electric cars, just changed form, and said Mercedes plans to grow its performance lineup by building AMG models on dedicated platforms. The interview also touched on Mercedes' broader software push. Its new C-Class Electric runs an AI assistant built into the car's operating system, and that same software underpins gas-powered Mercedes models too. The company is in the middle of launching 40 new models by the end of 2027, using new electric platforms that already produced the CLA, with nearly 500 miles of range, along with new C-Class and GLC versions. Källenius also admitted that mainstream buyers aren't fully sold on electric cars yet, even as the industry has "turned a corner." Mercedes says it's sticking with its long-term goal of going all-electric while still investing in advanced gas engines in the meantime. None of this changes rebates or programs for home chargers or solar, but it's a sign that automakers are betting harder on electric performance cars while keeping gas options around longer than once planned.
Tesla Cybercab Readies for Launch
This news is about self-driving robotaxis, not home energy upgrades, so it doesn't affect your house or any rebate program. But here's what's happening: Tesla plans to launch its Cybercab, a self-driving vehicle built without a steering wheel or pedals, on September 3 in Austin, Texas. Invitations for the launch event have gone out to select fans, investors, and influencers. For the Cybercab to work as designed, Tesla's self-driving software has to be fully ready to operate the cars with no human backup at the wheel. Tesla currently runs only a small robotaxi fleet in a few cities, and had earlier said it wanted robotaxis covering more than half the U.S. population by the end of 2025, a goal it did not meet. Now that Tesla has started actually producing Cybercabs, the question is whether the September 3 event will mean a real, large-scale rollout of thousands of these driverless vehicles, or just a small, high-publicity showing with limited numbers on the road. There's no rebate, incentive, or home-improvement angle here. If you're weighing energy upgrades for your house, this story doesn't change your options or timelines. It's simply a look at whether Tesla can deliver on its driverless-taxi ambitions.
Tesla Gets Robotaxi Permit in Nevada … for 10 Vehicles
This one is about robotaxis, not home energy upgrades, but here's what happened. Tesla asked Nevada regulators for permission to run 5,000 self-driving robotaxis in Clark County, home to Las Vegas, within a year. The state said yes to a much smaller test: 10 vehicles, limited to the Las Vegas Strip corridor. The approval comes with several restrictions. The robotaxis can't drive on roads with speed limits above 45 mph, and they can't pick up riders within half a mile of Harry Reid International Airport, even though Tesla wanted that access since airport trips are a big share of taxi business. The cars must be marked as "Robotaxis," and riders have to be told clearly that no human is driving. Despite that, Nevada isn't letting Tesla run these without a safety net — human monitors will still ride along. For context, another company, Zoox, already runs about 100 robotaxis on the Strip and has given hundreds of thousands of rides, but it built up to that scale gradually rather than launching all at once. Tesla appears to be starting down a similar slow-approval path. This has no bearing on home energy upgrades or rebates. It's simply a sign of how cautiously states are approving driverless vehicle programs, with small pilot fleets and tight geographic limits before any larger rollout.
Lynk & Co Partnership Comes to Life as CEV Trendyol EuroVolley 2026 Women Opens in Gothenburg
This is car company sponsorship news, not a home energy upgrade story. Automaker Lynk & Co is serving as the official car partner for the CEV Trendyol EuroVolley 2026 Women's tournament in Gothenburg, Sweden, providing a fleet of branded vehicles to transport teams and officials, plus a display area at the venue where fans can see the company's cars. The vehicles on show do have some relevance to home energy plans, mainly as a reference point on electric and hybrid vehicle technology. The Lynk & Co 08 is a plug-in hybrid SUV offering up to 200 km of electric range and recently drove 293 km on electric power alone to set a record. The Lynk & Co 02 is a fully electric model with up to 445 km of range, now updated for the 2027 model year with a new black exterior color, interior finish changes, and software features like faster start-up and personalized driver settings. For a homeowner, this doesn't change anything about rebates, weatherization programs, or heat pump incentives. If you're weighing an electric vehicle purchase alongside home upgrades like a Level 2 charger or solar panels, it's worth noting as one more data point on how far plug-in hybrid and electric range keeps climbing, but this piece is really about a sports sponsorship in Sweden, not a policy or program change that affects your house.
E-quipment highlight: 4,400 hp Wabtec FLXDrive electric locomotive
This is a story about mining trains, not home upgrades, but here's what happened. BHP, a mining company in Australia, has been running two battery-electric locomotives built by Wabtec at its Jimblebar iron ore mine for almost a year. Each locomotive has a 7 megawatt-hour battery pack (for scale, that's roughly 100 times the size of a typical home battery) and 4,400 horsepower, enough to haul up to 35,000 tonnes of ore. Instead of a diesel engine generating electricity like most freight trains, these run purely on battery power. The interesting part is the braking. The locomotives use regenerative braking, which captures energy while going downhill loaded with ore and feeds it back into the battery, similar to how an electric car recovers energy when you take your foot off the gas. On the right terrain, this braking can generate enough power to send the empty train back uphill for another load, meaning the battery might only need charging once, if ever, for a given route. BHP announced plans to add two more Wabtec locomotives, plus two from a different manufacturer, Progress Rail, arriving in 2027, so it can compare battery-electric locomotive technology from two companies side by side at the same site. None of this involves home equipment or rebates. It's a look at how battery and regenerative-braking technology, similar in principle to what shows up in electric cars and some home battery systems, is scaling up to heavy industrial use.
Suzuki Unveils it BEV Kei Car for Release This Autumn
Suzuki has unveiled the e SKY, its first fully electric "kei car" — Japan's category of small, low-power vehicles built for city and neighborhood driving. The car is set to launch in Japan this autumn, though Suzuki hasn't released pricing yet. It's built for short daily trips like commuting, school runs, and errands rather than long highway drives. The e SKY weighs about 1,030 kilograms and uses a 26-kilowatt-hour battery, giving it a reference range of 310 kilometers (not yet officially certified). It can fast-charge to 80% in about 25 minutes, or take roughly 4.5 to 8 hours on a home-style charger depending on the outlet used. It also has a heat-pump system, a more efficient way of heating and cooling the cabin that saves battery power, and can even run small appliances through a built-in outlet. Suzuki's approach here is notable: instead of building a bigger battery, engineers made the car lighter and more efficient to stretch range from a smaller pack. This isn't a vehicle expected to arrive in the U.S. market, since kei cars are a Japan-specific category with strict size and power limits. But it's a sign of where small, efficient EVs are headed — smaller batteries, lower cost, and less reliance on scarce battery materials, aimed at people whose daily driving is mostly local rather than long-distance. If you're weighing home EV charging as part of your own household's energy upgrades, it's worth watching whether similar efficiency-first EV designs eventually make their way to your own market.
Tesla raises Cybertruck prices by $5,000 despite abysmal demand
Tesla quietly raised Cybertruck prices by $5,000, with no changes to the truck itself. The Dual Motor all-wheel drive version now starts at $74,990, up from $69,990, and the Premium AWD went from $79,990 to $84,990. The top Cyberbeast trim stayed at $99,990. This isn't really a story about home energy upgrades, but it's worth knowing if you've been eyeing a Cybertruck as part of an electric vehicle and home solar setup. The price hike comes despite weak demand. Tesla built its Cybertruck factory to make up to 250,000 trucks a year but is currently selling fewer than 20,000, and has thousands of unsold trucks sitting in inventory. Pricing on the Dual Motor version has swung wildly over the past year, from a brief $59,990 offer down low to $74,990 now — a $15,000 range on essentially the same truck. If you're already planning to buy an EV, worth remembering that pairing it with home solar can cut charging costs close to zero, since electricity rates rose nearly 10% last year and are expected to keep climbing. Some solar options let you start with no upfront cost through leases or power purchase agreements, which is worth looking into regardless of which EV ends up in your driveway.
BMW i3 Touring captured on video for the first time [Video]
This is car news, not a home energy story, but here's the gist: BMW's electric i3 sedan is already on sale in Europe, and a wagon version, called the i3 Touring, has now been spotted on video for the first time, still wrapped in camouflage. It has a longer rear end and a sloped roofline, similar in shape to the Kia EV4 hatchback. The i3 sedan runs on BMW's new "Neue Klasse" electric platform with a 108.7 kWh battery, giving it a European range rating of up to 566 miles, or about 440 miles under the US rating system. It can fast-charge at up to 400 kW and regain roughly 250 miles of range in about 10 minutes. The Touring version is expected to have similar looks up front but likely less range than the sedan, plus a higher price, since BMW's wagon versions typically cost more than their sedan counterparts. None of this affects home electricity use or rebates directly, but it's worth knowing if you're weighing an electric vehicle purchase alongside home upgrades like a heat pump or added insulation, since EV charging can add meaningfully to household electricity demand. BMW has started building the i3 in Munich, with US deliveries of the 2027 model expected this fall. More details on the Touring wagon are expected soon.
BYD’s low-cost electric hatch is about to get a bigger sibling
This one is car news, not home energy news, so it won't affect any home upgrade or rebate plans. Briefly, for context: Chinese automaker BYD is launching a new electric hatchback called the Great Seagull, a bigger version of its budget Seagull model (sold outside China as the Dolphin Surf or Dolphin Mini). The current Seagull starts at about $10,000 in China and has been one of the best-selling EVs in the world. The Great Seagull will be noticeably larger than the current car and will use a more powerful electric motor. BYD hasn't released battery details or pricing yet, but the car is expected to cost a bit more than the current Seagull and may include newer battery and fast-charging technology, along with upgraded safety and interior features. BYD says the car will go on sale by the end of 2026. None of this affects home energy upgrades or rebate programs. It's simply an update on a new international EV model from BYD, a Chinese automaker that does not currently sell vehicles in the U.S.
Robot vacuum company cancels its rocket-boosted electric hypercar
Dreame, the Chinese company known for robot vacuums and other home appliances, has scrapped its plans to build electric cars. The company had announced last year that it wanted to make luxury electric hypercars, unveiled a model at CES this year, and even floated a rocket-boosted version meant to hit 0-60 mph in under a second using solid rocket boosters (thrusters that add a burst of power beyond what the tires alone could handle). That rocket idea was always impractical, since the boosters would need to be swapped out or recharged after each use. Now the whole car program is gone. Reports say Dreame had close to 1,000 people working on the effort at its peak, but layoffs have been ongoing for months. Sources cited in Chinese media suggest the car project may have been more about marketing and raising money than actually building vehicles, and that the department wasn't structured to spend on real research and development. This isn't a home energy or rebate story, and it has no direct effect on your house, your utility bills, or any incentive programs. It's simply a sign of how many companies outside the auto industry have tried, and often failed, to break into electric cars — Dreame joins Apple and the Sony-Honda joint venture on the list of scrapped EV projects. If you're a Dreame vacuum owner, the news doesn't change anything about your appliance.
HVAC Groups See Promise, Problems in Latest Senate-Led Federal Efficiency Bill
A bill introduced in the Senate on August 6 by Sen. Mike Lee would rewrite how the Department of Energy sets efficiency rules for appliances and heating and cooling equipment. The Energy Efficiency Reform Act of 2026 would lock in DOE's "Process Rule" (the method DOE uses to decide if a new efficiency standard makes sense), drop the current requirement that DOE review equipment standards every six years, add new hurdles before DOE can split products into new categories, and give federal standards stronger power to override state rules, including state bans on equipment based on fuel type. For homeowners, none of this changes anything right away. It's a proposal, not law, and its real effect depends on whether Congress passes it and how DOE later writes the actual regulations. But the direction matters for future furnace, air conditioner, and heat pump purchases: industry groups say ending mandatory reviews could mean standards change less often, while stronger federal preemption could limit how much your state can set its own rules on what equipment can be sold or installed locally. Trade groups are split. Some support locking in clearer, more predictable rules so manufacturers and distributors aren't caught off guard by shifting requirements. Others warn the bill leaves out a fix for a separate problem — equipment stuck unsold when regional efficiency deadlines are tied to installation dates rather than manufacture dates — which can leave distributors transporting equipment long distances, undercutting the energy savings the equipment is supposed to provide. For now, this is a proposal to watch, not something that changes what you can buy or install today.
U.S.-Canada Trade War Escalates as 50% Tariffs Take Effect
Trade tensions between the U.S. and Canada have escalated sharply, with new 50 percent U.S. tariffs on nearly $20 billion in Canadian imports taking effect after weekend negotiations broke down. The tariffs cover hundreds of categories, including wine, cement, plywood, and furniture, and apply even to goods that otherwise qualify under North American trade rules. Canada has announced matching tariffs on U.S. goods starting after Labor Day. These new duties are separate from existing tariffs on steel, aluminum, and copper. For homeowners planning HVAC or other equipment purchases, the practical concern is cost and availability. Industry groups say tariffs on steel and aluminum, materials used in compressors, coils, cabinets, and other HVAC parts, have already pushed up bid prices and lengthened wait times for equipment. There is one exception worth knowing: since June 2026, the tariff on certain residential HVAC equipment was lowered from 25 percent to 15 percent, and equipment made with at least 85 percent U.S. steel or aluminum can qualify for an even lower 10 percent rate. That carve-out is set to last through December 2027. Beyond that, the outlook is uncertain. Economists had thought tariff-driven price increases were leveling off, but this new round, layered on top of already higher energy and transportation costs, could mean another price increase for HVAC equipment and related home projects. If you're planning a heating or cooling upgrade, it may be worth asking installers directly whether current quotes reflect these tariff changes.
HVAC-Related Crimes on the Rise
Reports of HVAC-related crime are climbing in some areas. In Atlanta, thieves have been stealing copper parts and even entire air-conditioning units from homes and businesses, and the problem has grown bad enough that residents are taking extra steps to protect their equipment. Outdoor AC units and condensers, which contain copper coils and tubing, are common targets because copper can be sold for scrap value. Separately, there have been reports of violent incidents involving HVAC workers, including a case where a technician shot a co-worker on the job. These are being cited as reminders of the risks that can come up around service calls and job sites. For a homeowner, the practical concern is equipment theft. An outdoor AC unit or heat pump sitting in a yard or alongside a house can be an easy target, especially in areas where thefts have been on the rise. If you live somewhere with reported copper or unit theft, it may be worth checking whether your unit is visible or easily accessible from the street, and whether your homeowner's insurance covers theft or damage to outdoor equipment. There's no new program, rebate, or rule change here — just a trend worth being aware of if you have outdoor HVAC equipment at your home.
Bills rise when utilities use conflicting forecasts to drive gas and electric investment
A new analysis points to a costly mismatch inside utilities that sell both gas and electricity: their two divisions are sometimes planning for different futures, and customers end up paying for both. In upstate New York, National Grid's electric division expects over 30,000 more heat pump installations by 2030 than its gas division assumes. Because the gas side is planning as if that shift away from gas heating won't happen, it's set to spend $550 million by 2029 on growth-related infrastructure that may not be needed if its own electric division's forecast is right. Researchers estimate the gas utility could end up serving about 15,000 fewer customers than planned. This matters to your wallet because infrastructure spending like this makes up a large share of both gas and electric bills — about 75% in New York, according to the piece. Under current trends, National Grid customers could see bills rise roughly $300 a year for both gas and electric service by the end of 2027. The concern is that when a utility's gas and electric arms use conflicting assumptions about how many households will switch to heat pumps, one side risks overbuilding infrastructure that goes underused, and ratepayers cover the cost either way. New York is now considering ways to fix this through "integrated" gas-and-electric planning, which would require both divisions to work from the same assumptions before spending money. A bill in the state Senate (S5995) would push regulators in that direction, and some utilities, including Consolidated Edison and Central Hudson, have already started similar pilot efforts. If your utility serves both gas and electricity, this kind of planning mismatch could be showing up in your own bill, even if it hasn't made headlines yet.
Q&A Spotlight: Flashing Strategy for an Exterior Renovation
A homeowner in Boston is redoing the exterior of a 1960 Cape-style house and ran into a common problem: how to seal the joint where a brick chimney meets the wall so water can't get in. He's stripped the old cedar shingles, fiberboard, and tar paper down to the wood sheathing, and plans to add a water-resistant barrier (a sheet material that blocks water but lets some moisture escape), then 2 inches of wood-fiber insulation board, a small air gap called a rainscreen, and new siding. His plan was to tape the brick to the water barrier with a specialty flashing tape, then caulk the gap between the new siding and the chimney once it's installed. This kind of detail matters because chimneys are one of the trickiest spots on a house to waterproof. The masonry and the wood-framed wall move differently as temperatures change, and any gap where they meet is a likely spot for water to sneak behind the siding and rot the wall over time. If you're planning a similar exterior renovation with added insulation, rainscreen gap, and new siding, the area around a masonry chimney is worth extra attention, since standard flashing details made for two wood surfaces don't always work the same way against brick. No product names, costs, or rebate programs were part of this discussion, so there is nothing here that changes eligibility for weatherization or efficiency incentives. It is simply a construction detail worth knowing about if a chimney is part of your own exterior upgrade plans.
Clean energy investments fall dramatically in Appalachia
Clean energy spending in Appalachia has dropped sharply after a boom driven by federal incentives like the Inflation Reduction Act. Two research groups, the Keystone Research Center and ReImagine Appalachia, report that in Kentucky, Ohio, Pennsylvania, and West Virginia, clean energy deployment is down 17% from its 2024 peak, and clean energy manufacturing investment is down 26% from its late-2023 high. Nationally, private construction spending on manufacturing has fallen from a peak of $249 billion to $170 billion, and the country has lost 277,000 manufacturing jobs since January 2024. Researchers tie the slowdown to a pullback in federal clean-energy policy support. The region has a lot riding on this. Appalachia includes many "energy communities" — areas historically dependent on coal and other fossil fuels — that had been targeted for extra tax credits under the IRA to attract new solar and other clean energy projects. A separate report from December found that two-thirds of the region's roughly 93,000 clean energy jobs were at risk under current federal policy. There is one bright spot for homeowners: even as large-scale investment slows, individual consumer spending on clean energy and electric vehicles kept rising in 2026, according to the researchers, because solar panels and batteries keep getting cheaper. This is a regional and national policy story rather than a specific program change, so it does not affect any particular rebate or incentive you might already be using. But it's a sign that the broader climate for federal clean-energy support in coal-country states remains unsettled.
PJM has finally greenlit a lot of new clean power. Can it get built?
PJM, the grid operator serving 67 million customers across 13 states, has finally cleared more than 50 gigawatts of solar, wind, and battery projects to connect to its power grid, some after waiting since 2018. That backlog is a big reason electricity has gotten more expensive in this region — the grid can't add power fast enough to keep up with rising demand, much of it from data centers. Getting these already-approved projects actually built could help slow rate increases: one analysis found that adding 10 gigawatts of solar and wind by 2028 could save ratepayers in the region nearly $11 billion over a decade. But winning approval to connect is not the same as getting built. Utilities still have to complete grid upgrades, which researchers say utilities often delay because they earn more profit from other types of projects. Developers also need permits and contracts to sell their power before they can secure financing. Historically, more than 40 percent of projects that got this kind of approval nationwide have ended up dropping out entirely. Big tech companies building data centers could speed things along by signing contracts with these already-approved clean energy projects — some states, like New Jersey and Illinois, are pushing data centers to do exactly that. Batteries in particular could get built faster than new gas plants, which face years-long construction backlogs. None of this requires action from individual homeowners, but if these projects move forward, it could mean slower growth in electricity rates in PJM states, which include much of the mid-Atlantic and parts of the Midwest.
Foss & Company closes $150 million Section 48E tax equity deal for Illinois distributed energy portfolio
A group of investors has put about $150 million into a batch of solar projects in Illinois, run by a partnership between Summit Ridge Energy and Apollo Global Management. The money comes through a financing method called tax equity, where companies like banks and insurance firms fund clean energy projects in exchange for tax credits. This particular deal is one of the first done under a newer federal tax credit rule, called Section 48E, which replaces older solar-specific credits with a broader "technology-neutral" version and adds stricter rules about where equipment can come from, to keep out gear tied to certain foreign entities. For homeowners, the direct effect is limited, but the details show how these projects can lower costs for participants. More than half the portfolio will take part in Illinois' Adjustable Block Program, a state program that locks in 15- to 20-year contracts for renewable energy credits, with some contracts specifically tied to low-income subscribers. The projects also qualify for extra federal credits for using U.S.-made equipment, for being built in areas with a history of energy industry jobs, and for serving lower-income households. This is the eighth such deal between Foss & Company and Summit Ridge Energy, and the companies say it sets a model for structuring future deals under the new federal rules. If you live in Illinois and are weighing community solar subscriptions or watching for local clean energy programs, this signals continued investment in that space, backed by both state contracts and federal tax incentives.
How a Toyota dealer cut energy costs 55%, even with DC fast chargers
A Toyota dealer on Long Island, Sunrise Toyota, cut its energy costs by an average of 55% over three months by combining solar panels, battery storage, DC fast EV chargers, and software that automatically manages when power gets used and stored. The dealership, which operates locations in Oakdale and Medford, New York, had been facing rising utility bills, made worse by new DC fast chargers Toyota required it to install. Fast chargers can cause sudden spikes in power draw, and commercial customers often get charged extra for those spikes, separate from their regular electricity use. To solve this, a company called Sprocket Power built a system that pairs onsite solar with batteries and AI-driven software. The software decides when to store solar power and when to release it from the batteries, smoothing out those demand spikes and even earning bill credits by participating in utility grid programs. According to the companies involved, the setup reduced peak power draw by up to 101 kilowatts and kept the batteries running 99% of the time, with a projection that the dealership could eventually cut its net utility costs by 90% and pay off the investment in five years. These figures come from the companies themselves and haven't been independently verified. This is a commercial project, not a homeowner program, but it points to a trend worth knowing about: pairing solar with home battery storage can do more than provide backup power during outages. It can also help manage electricity costs tied to how power is used throughout the day, a factor increasingly relevant as more homes add EV chargers and other high-power devices.
CEI – Windows innie vs outie vs ? in a wildfire area. Which to choose?
A homeowner in a wildfire-prone area, building or remodeling a house with continuous exterior insulation (a layer of rigid insulation, like mineral wool, wrapped around the outside of the wall framing), is weighing how to install windows without weakening that fire-resistant layer. The insulation, paired with metal furring strips and non-combustible siding such as fiber cement, acts as a backup barrier if ember screens fail during a fire. The question is which window installation method keeps that protection intact. Two common approaches came up. In the "outie" method, a wood frame (called a buck) extends outward through the insulation so the window sits flush with the exterior siding. The concern is that this wood buck pokes through the non-combustible layer and connects directly to the house's timber framing, so if the buck catches fire, flames could spread straight into the structure. The alternative, sometimes called a "window-integrated jamb" approach, keeps more of the wood trim separated from the main framing by the insulation layer, which might contain a fire to the window area rather than letting it reach the framing. For homeowners in fire-prone regions planning window replacements or new construction with exterior insulation, this is a reminder that the choice of window installation detail isn't just about energy performance, cost, and looks. It can also affect how well the wall resists ember intrusion and fire spread, so it's worth discussing installation method with whoever designs or builds the wall assembly.
Enphase enters commercial battery storage market, announces IQ Battery C80
Enphase, the California company known for home solar and battery equipment, has launched its first battery system built for commercial and industrial buildings rather than houses. The IQ Battery C80 is aimed at sites like schools, retail stores, offices, and warehouses, with shipments expected to start in early 2027. This is not a product for homeowners. It stores 80 kWh of usable energy, far more than a typical home battery, and arrives pre-assembled to cut down on installation work. It uses lithium iron phosphate battery chemistry, the same type increasingly common in home batteries, along with fire-safety features like smoke and gas detection and an automatic fire-suppression system. The unit is rated to run for 15 years or 7,000 charge cycles, whichever comes first. Because the system is designed and built with a set amount of domestic content, it can help commercial project owners qualify for bonus tax credits under the federal Investment Tax Credit (ITC). It also works with Enphase's software to shift energy use, cut demand charges, take advantage of time-of-day electricity rates, and participate in virtual power plant programs, where utilities tap batteries during high-demand periods. For most homeowners, this news simply signals that Enphase is expanding beyond residential solar and storage into bigger commercial projects. It does not change anything about the home battery products Enphase already sells, but it may hint at technology or features that eventually show up in future home systems.
Tesla ditches solar roof — and embraces regular solar panels
Tesla has quietly dropped its solar roof, the shingle-like tiles that generated electricity while looking like a regular roof. The product is no longer listed among home energy options on Tesla's website. It never caught on: Tesla installed only about 3,000 of the roofs nationwide by the end of 2022, a tiny sliver of both the roofing and home solar markets. The roofs cost far more than standard setups, took longer to install, and sometimes warped or produced less power than promised. A competitor, GAF, made a similar product but closed its California solar shingle factory last December and moved operations to Texas. Instead, Tesla is now making conventional rooftop solar panels — a sleek, all-black design, but functionally a standard panel — at its factory in Buffalo, New York. This is a shift from trying to reinvent the roof to simply building ordinary panels at scale, which is generally what has worked best in the solar industry. Separately, Tesla has floated a much bigger and less certain project: a possible $10.1 billion solar cell factory near Houston, which could begin construction this year and finish by 2029. Solar cells are the components that actually convert sunlight into electricity, and the U.S. currently doesn't make enough of them to supply its panel factories. New tariffs on imported solar products have added pressure to build more domestic capacity. None of this changes what's available to homeowners today, but it suggests Tesla is moving away from specialty roofing products and toward standard panels made in larger volume.
Solar panel makers and buyers have mixed feelings on Sec. 232 tariffs
New tariffs are set to raise the cost of solar panels, and the people who make them aren't happy about it either. Starting December 4, 2026, the government is putting a 15% tariff on imported solar wafers, cells, and finished panels, plus a minimum price floor on imported polysilicon (the raw material used to make solar cells). The idea is to boost U.S. manufacturing, but panel makers say it backfires: American factories still have to import most of the upstream parts (silicon, wafers, cells) at these new higher prices, since the U.S. barely makes any of that material itself. That pushes up the cost of domestic panels too, sometimes to the point where they struggle to compete with imports even after the tariff. One manufacturer said he's already quoting customers at much higher prices than a month ago. Companies that only make cells, rather than complete panels, say the math is especially bad, since their costs now exceed what they can charge, even with tax credits factored in. This may push more companies toward building fully integrated factories that make both cells and panels. For homeowners, this mostly means solar panel prices are likely headed up, though how much and how soon depends on your supplier and location. Large solar developers say the effects on utility-scale projects may take a year or two to show up, since many already have panels stockpiled. Smaller residential and commercial installations could feel the price shift sooner.
