Could Your Next HVAC Technician Come From Prison?
Washington state is training prison inmates for careers in heating and cooling work, a program that could eventually mean more licensed technicians available to service home HVAC systems. At Coyote Ridge Corrections Center in eastern Washington, inmates without a high school diploma can enroll in a program that combines basic education with hands-on HVAC training. Graduates earn EPA 608 certification (required to handle refrigerants), complete OSHA safety training, and gain 1,265 of the 2,000 work hours needed for Washington's specialty electrical license, which technicians need to work unsupervised on HVAC equipment. Since only 1,000 hours are required to work without direct supervision, graduates leave with real progress toward working independently. The program is part of a broader push in a few states to offer vocational training in prisons, including trades like welding and roofing. Washington reports the investment pays off, with roughly $40 returned for every $1 spent on programs like this one. Supporters say the training also helps address a nationwide shortage of HVAC workers. For homeowners, this isn't about a new rebate or upgrade to plan for. It's a sign that the pool of trained, certified HVAC technicians may be growing through less conventional channels, potentially easing the labor crunch that has made it harder in some areas to find available installers for furnace, air conditioner, or heat pump work.
Why energy bills may keep rising, even as utilities join Trump’s AI ratepayer pledge
Nearly 200 utilities and tech companies, including American Electric Power, NextEra Energy, Duke Energy, Southern Co., Amazon, Google, Microsoft, and Meta, have signed a voluntary pledge backed by the White House. It calls for data center developers to pay for their own energy needs instead of shifting those costs onto regular customers. But the pledge isn't a law or regulation, and it may not do much to stop bills from rising. Even as utilities tout savings from data center deals, they've also asked state regulators to approve $18.6 billion in rate hikes this year, and analysts expect more increases ahead. That's because rate hikes usually come from many sources beyond data centers, including transmission line upgrades, storm repairs, and rising gas and electricity prices. Some specific deals show the tension: Michigan utility DTE promised to hold off on new rate requests until 2028 after a Google data center deal, but the state has already approved close to $500 million in increases since 2025, with another $500 million requested. In Louisiana, Entergy says a deal with Meta will save customers billions, but a separate plan to buy an aging gas plant has drawn concern that it will mainly serve Meta's data center while raising costs for everyone else. Because the pledge carries no enforcement power, analysts say real protection for ratepayers would need to come from federal regulators or state legislatures, not from voluntary corporate promises. For now, whether your own bill goes up may depend more on your state's rules than on this pledge.
The secret to a better grid? Electric vehicles.
A coalition of utilities and energy companies — Eversource, National Grid, EnergyHub, Sunrun, and the Mobility House — is launching an early test in Massachusetts of vehicle-to-grid technology, or V2G, which lets electric vehicles send power back into the electric grid, not just draw from it. Participants join an existing program called ConnectedSolutions, and during "demand response" events, like a heat wave, their EV batteries help supply the grid. In exchange, owners get paid, similar to homeowners who sell back solar power. The discharging only happens for a small number of hours a year, not daily. To take part, you need a bidirectional charger, hardware that lets electricity flow both ways between your car and your house or the grid. Not all EVs support this yet, though more models, including the Nissan Leaf, are being built with it. An EV battery holds roughly six times the capacity of a typical home backup battery, and only a fraction of owners in an area would need to participate for the system to help meaningfully, since utilities can pool many batteries together. For homeowners, this isn't an upgrade you need to make now, but it points to where things are headed: EVs increasingly doubling as backup power sources that can earn their owners money while easing strain on the grid during peak demand. As bidirectional chargers get cheaper and more common over the next few years, this kind of program may become more widely available beyond Massachusetts.
What I’ve Learned Here in the Epicenter of Very Unhealthy Air Recently in Wisconsin
Wildfire smoke from Canadian fires has settled over Wisconsin and much of the eastern US recently, driven by heat and drought conditions. The smoke carries fine particles smaller than 2.5 microns, small enough to get deep into lungs. A similar problem shows up in some western valleys during winter, when an "inversion" traps car and wood-stove pollution close to the ground instead of letting it rise and disperse. For home air, most HVAC systems run MERV 8 filters (MERV rates how well a filter traps particles). If your system has a 4-inch filter slot, you can step up to a MERV 11 filter, which catches roughly 85 percent of particles in the 3.0 to 10.0-micron range and also grabs a good share of smaller ones. A MERV 13 filter removes more of the smallest particles but can strain your HVAC's fan motor, so a stand-alone HEPA air filter may be a better route if you want stronger filtration without stressing the system. For homes without central air, a portable window or standalone air conditioner is an option, and some models include filtration. On masks: surgical masks only filter 20 to 30 percent of smoke particles, not much protection. N95 masks, left over from the pandemic, filter at least 95 percent of airborne particles down to 0.3 microns, including smoke, and are worth digging out on bad air days. Commercial buildings built to ASHRAE standards are required to use MERV 13 filtration or better, a useful benchmark if you're comparing your own home's setup.
Go beyond the conference with Greenbuild 2026 tours across NYC
This one's more for industry professionals than homeowners, but a few details are worth knowing if you're curious about what's possible in home energy upgrades. The Greenbuild 2026 conference is running building tours across New York City on October 19 and 23, open to registered conference attendees, showing off large-scale green building projects. A couple of tours touch on technology that scales down to houses. One stop is a Brooklyn townhouse retrofit that earned Passive House certification (a standard for very airtight, well-insulated buildings) back in 2018, with triple-glazed windows, solar panels, a heat pump for heating and cooling, induction cooking, and a green roof. Another is a Manhattan building retrofit that cut heating energy by 70% and total energy use by more than half using an all-electric Passive House approach — proof that older buildings can be converted to highly efficient, electric-only systems without losing character or historic approval. None of this is a program you can sign up for or a rebate you can claim — it's a professional conference with guided site visits. But if you're weighing whether serious insulation and air-sealing work, plus a switch to heat pumps, can actually deliver big energy savings in an existing structure, these real-world examples are evidence that it works, even at large scale.
Massachusetts open to bidirectional EV and V2G setups
Utility companies Eversource and National Grid are teaming up with EnergyHub, Sunrun, and The Mobility House to test vehicle-to-grid, or V2G, technology in Massachusetts. V2G lets an electric vehicle send power back to the grid, not just draw power from it, turning a parked EV into a small backup energy source. Under the test, customers of Eversource or National Grid who own a V2G-capable EV can enroll in ConnectedSolutions, an existing program that already uses home batteries, smart thermostats, and other equipment to help ease strain on the grid during high-demand periods. Massachusetts has more than 150,000 EVs on the road, and more bidirectional-capable models are coming to market. That gives utilities a growing pool of potential backup capacity they can tap during peak demand, in exchange for benefits to participating customers. National Grid is also testing V2G with school bus fleets, and Eversource is talking with school districts about a similar offering called ConnectedSolutions+. If you own an EV in Massachusetts and it supports bidirectional charging, this program may eventually let you enroll it to help manage grid demand, alongside home batteries and thermostats already eligible under ConnectedSolutions. The effort is described as a test at this stage, so details on enrollment, eligible vehicle models, and any compensation were not specified. Homeowners elsewhere can check whether their own utility offers a similar demand-response program for EVs or home batteries.
Voters Know America Needs More Energy. Solar & Storage Are the Overwhelming Choice.
Utility bills are up, and new polling finds most Americans call them hard to afford. New surveys, including from Gallup and Pew, show broad public support for building more solar power, with majorities in both parties backing it. Some polling firms that work with Republican candidates found similar support among Trump voters in swing states. Rising demand from data centers and factories has added to worries about where future power will come from and what it will cost. Solar and battery storage keep coming up as the fastest and cheapest options to add to the grid. Unlike gas or oil plants, they have no fuel costs, so they are less exposed to price swings from fuel markets. They can also be built in months rather than years, and together they have made up more than 80 percent of new power added to the U.S. grid in recent years. Supporters point to billions in factory investment and hundreds of thousands of jobs tied to the industry. None of this changes what any homeowner needs to do right now. It is a snapshot of public opinion and energy trends ahead of this year's midterm elections, showing that solar and storage have become popular, bipartisan answers to complaints about high electric bills. If that popularity shapes future energy policy, it could affect the cost and availability of solar and storage options for homes down the road, but no new program, rebate, or deadline has been announced.
Solar is booming in Indiana. Not everyone is happy about it.
Indiana has quietly become one of the country's biggest builders of large-scale solar power. Last year it ranked third in the nation for new solar installations, behind only Texas and California, driven partly by demand from data centers seeking clean electricity. But as solar farms multiply across the state, so has pushback from residents worried about losing farmland, falling property values, and changes to the rural landscape where projects go up. That opposition has real consequences. A recent study found local resistance is a top reason county officials in Indiana reject solar projects, even when the economics look favorable. Indiana has no statewide siting rules, so each of its 92 counties sets its own regulations, and researchers found more counties currently discourage solar than welcome it: 11 have outright bans, 20 have restrictive rules, and only 24 are considered favorable. One economic analysis estimated that counties with restrictions missed out on thousands of jobs and tens of millions in investment over two decades. Solar actually uses a tiny sliver of Indiana farmland, far less than golf courses, but that fact hasn't quieted the debate. Researchers say the developers who fare best are those who show up early and often at community meetings, fairs, and hearings, rather than appearing only when a project needs approval. For homeowners, the takeaway is that whether a solar farm ends up nearby, and on what terms, depends heavily on your own county's rules and how engaged local officials and developers are with residents.
People are critical infrastructure, too. Utilities must do more or lose talent to tech.
This is an industry opinion piece about a workforce shortage at electric utilities, driven mostly by the surge in data centers built to run artificial intelligence. AI computing needs huge amounts of electricity, and one estimate cited puts U.S. data center demand at 426 terawatt-hours by 2030. Building the power lines, substations and grid upgrades to supply that demand takes specialized engineers, technicians and project managers, and the piece argues utilities don't have enough of them. Nearly half of U.S. engineers are now 50 or older, and utilities are competing with tech companies for the same skilled workers, especially at smaller and rural utilities with fewer resources. The author, a staffing-industry executive, argues utilities need to treat workforce planning as seriously as they treat financing and construction, through training current employees, partnering with schools, and building local pipelines of workers. There is no direct action for homeowners here. But it points to a real possibility worth watching: if utilities can't staff up fast enough, grid upgrades needed to support new demand, including rooftop solar hookups, EV charging capacity, and reliability improvements, could take longer to arrive in some areas, particularly smaller or rural utility territories. It is not a program or rebate, just a structural pressure on how quickly the grid serving your home gets modernized.
Renewables, storage can meet one-third of US industrial heat demand: report
A new analysis from University of California, Berkeley researchers finds that on-site wind and solar, paired with industrial heat pumps and heat storage, could economically supply up to one-third of U.S. industrial heat demand by 2035. The researchers looked at more than 3,000 industrial sites nationwide and found this approach works best in places with expensive natural gas and cheap renewables, including California and parts of the Northeast. Heat pumps came out as the most cost-effective option for lower-temperature processes, while thermal batteries were competitive for higher-temperature ones. This is industry-level research, not a homeowner program, but it points to the same technology showing up in houses: heat pumps that move heat instead of burning fuel to make it, and batteries that store energy for use later. The report's authors argue these systems are now often on par with fossil fuel costs, and getting cheaper as renewable power prices keep falling. The study also flagged limits. About 27% of industrial heat demand sits at facilities, often in cities, that don't have enough local wind or solar potential to make this work. Researchers said many industries still aren't aware these options exist. None of this changes rebates or programs available to homeowners, but it's a sign that heat pump and storage technology is gaining ground well beyond the residential market, which could help push prices down and improve the technology further over time.
Schneider Electric’s upgraded app-free EV charger now has NACS
Schneider Electric has updated its Charge Pro Level 2 EV charger, a commercial charging station used at apartment buildings, workplaces, and public charging sites. The update adds support for NACS, the Tesla-style plug now becoming standard across the industry, alongside the older J1772 connector. That matters because it means more EVs, including Teslas, can plug in without an adapter at locations using this charger. The new version also drops the requirement for a charging app. Drivers can start a session by scanning a QR code instead of creating an account, which is meant to help people who charge only occasionally, such as hotel guests. The charger comes with a year of included software for the site owner to monitor usage and manage access, a five-year hardware warranty, and a faster setup process. Schneider says the system can also work with its broader electrical equipment, like panelboards and switchgear, to manage power use so a site can add chargers without needing a full electrical upgrade. This is aimed at businesses and building owners installing shared or public charging, not at single-family homes. But if you live in an apartment, use a workplace charger, or rely on charging at hotels or other public spots, this kind of upgrade could mean easier, app-free charging and more compatibility with your car's plug type at newly installed stations. The charger is now available through Schneider's distributors and certified installers.
Massachusetts wants to pay EV drivers for their battery power
If you own an electric car in Massachusetts, you may soon be able to get paid for letting your car's battery help power the grid. Utilities Eversource and National Grid are adding electric vehicles to ConnectedSolutions, their existing programs that already pay people for using smart thermostats or home batteries to ease strain on the grid during high-demand periods. Now they want to test whether EV batteries can do the same job through what's called vehicle-to-grid (V2G) technology, which lets a car send stored electricity back into the grid instead of just drawing power from it. The catch is that a lot of details are still missing. The utilities haven't said which EV models or bidirectional chargers will qualify, when you'd be able to sign up, or how much you'd actually get paid. Companies including Sunrun and The Mobility House are providing the technology behind the pilot, and National Grid is already testing V2G with electric school buses, while Eversource is talking with school districts about similar programs. For now, this mainly matters if you own or are considering an EV capable of bidirectional charging and live in Eversource or National Grid territory in Massachusetts. There's no program to join yet, but it's a sign that using your car's battery to earn money or lower grid strain could become a real option in the state, alongside the smart thermostats and home batteries already enrolled in ConnectedSolutions.
New Report Outlines Priorities for a Cybersecure, American-Made Solar & Storage Industry
The Solar Energy Industries Association, the main trade group for the solar industry, has released a report on cybersecurity and domestic manufacturing for solar panels and battery storage systems. The report responds to growing cyber threats aimed at the energy sector and lays out priorities for keeping solar and storage equipment secure while building up U.S.-based supply chains for these products. The group points to recent manufacturing growth as context: U.S. production of inverters, the devices that convert solar power into electricity usable in a home, has nearly tripled since the end of 2024. With a new inverter factory opening this month, the U.S. is now tied for second place worldwide in inverter manufacturing. The report recommends expanding domestic manufacturing further, setting more consistent cybersecurity practices across the industry, and improving how companies share information about emerging threats. For homeowners, this is industry-level planning rather than a change to any specific rebate, incentive, or product on the market today. It signals that more solar and storage equipment may be built in the U.S. going forward, and that the industry is working to make the software and systems behind solar panels and home batteries more resistant to hacking. There is no new program, deadline, or dollar amount here that affects what a homeowner would pay or qualify for right now.
Double wall design and condensation
A homeowner in Nova Scotia is planning a new single-story house on screw piles and asked for advice on a "double wall" design: drywall, a 2x4 stud wall with fiberglass insulation, a 5-inch layer of rigid foam in the middle, a second 2x4 stud wall with fiberglass, plywood sheathing with taped seams, a moisture barrier, and metal siding outside. The question was about whether this would work and what kind of moisture barrier to use. A building science expert responded that the "moisture barrier" the homeowner meant is really a WRB, or weather-resistant barrier, something like Tyvek housewrap installed over the exterior sheathing, behind the siding. He warned against using poly sheeting in this spot, since the thick foam layer in the middle already blocks moisture flow well, and adding poly would create a "double vapor barrier" problem that can trap moisture inside the wall. The expert also questioned the overall design. He said these foam-in-the-middle double stud walls tend to cost more and take more labor to build, without necessarily performing better. Instead, he suggested skipping the rigid foam layer entirely and simply filling the same wall depth with thicker fiberglass batts or dense-packed cellulose insulation. By his rough math, that approach could reach roughly R41, a strong insulation value, without the added expense and complexity of the foam layer. For anyone considering a similar double-wall build, the exchange is a reminder that adding foam to a wall assembly isn't always the most efficient path to a well-insulated, moisture-safe house, and that WRB placement and vapor-barrier choices matter for avoiding trapped moisture.
Smart wall design
This one's a forum question from someone planning a new wall build, not news you need to act on. The homeowner is comparing two ways to frame an energy-efficient wall and asked other builders for opinions. The first plan uses standard 2x4 framing with plywood sheathing, a peel-and-stick weather barrier, foam board on the outside under vinyl siding, and dense-pack cellulose insulation inside the wall cavity. It also includes spray foam around the rim joist and headers, plus a "smart" vapor retarder (a membrane that adjusts how much moisture passes through depending on humidity) and an extra service cavity inside to hold wiring and plumbing without puncturing the air barrier. The second option swaps in a manufactured product called Insul-Stud, which replaces a standard 2x6 stud with two thin strips sandwiching rigid foam insulation rated at R-19 (a measure of insulating power). Paired with taped structural sheathing, a thin rain screen gap, and spray foam in the wall cavity, this version simplifies the building steps and, according to the poster, costs less to buy and ship. There's no verdict yet — the question had no replies as of this posting. If you're planning a new build or a major wall reconstruction, this illustrates two legitimate approaches to a high-performance wall, but neither is inherently the "right" answer for every house, climate, or budget.
Utilities & Big Tech Pay Lip Service, “Pledge” to Keep Costs Down
A group of utilities and tech companies is signing onto a new pledge promising to keep electricity costs down as data centers built for artificial intelligence drive up demand on the power grid. The pledge is voluntary and has no binding rules behind it. The Sierra Club, an environmental group, says the pledge is mostly words so far. It points to Duke Energy, one of the companies signing on, which received a failing grade on the group's report card for keeping old coal plants running and building new, costlier gas plants that ratepayers end up paying for. The Sierra Club's own tracking shows utilities nationwide planning nearly 50 percent more gas power plants than are currently running, largely to meet the electricity needs of data centers. The group argues there are too few rules requiring that tech companies, rather than everyday customers, cover these rising costs. It also notes the Trump administration has cut billions of dollars in funding for clean energy projects, even though the group says clean power is the cheaper, lower-risk option for meeting this new demand. For homeowners, the takeaway is that data centers are becoming a growing driver of electricity costs nationally, and the industry pledges meant to address this so far come with no enforcement or spending commitments attached. Whether and how this affects your own bill will depend on your utility and state, since gas plant construction and cost allocation vary widely by region.
IEA: Global power demand is surging – and renewables are passing coal
Global electricity use is climbing fast, and renewables are on track to become the world's top power source this year, according to a new report from the International Energy Agency. Demand is projected to grow 3.6% in 2026 and 3.8% in 2027, pushed up by industry, air conditioning, appliances, EV charging, and data centers. Solar is leading the shift: generation is expected to grow by about 600 terawatt-hours in 2026, matching last year's record pace, and solar is set to pass wind as the world's second-largest renewable source after hydropower. This growth is happening while natural gas markets are under stress from conflict in the Middle East, which disrupted shipments of liquefied natural gas (LNG, gas cooled for transport by ship) through the Strait of Hormuz and pushed gas prices in Asia and Europe to their highest levels since the 2022-23 energy crisis. Some countries responded by switching from gas back to coal, which is expected to push global power-sector emissions up about 1% this year before leveling off in 2027 as renewables and nuclear power keep growing. None of this changes rebate programs or equipment costs for your home directly, but it's a sign of where energy prices and supply may be headed. Regions leaning more on solar and other renewables were better insulated from the recent gas price spikes, while areas still dependent on imported gas saw sharper cost swings. Homeowners considering solar, batteries, or electric equipment may see this broader shift in the grid as part of the backdrop for their own energy decisions.
FERC eyes ‘grid-enhancing technology’ incentives: Chairman Swett
The Federal Energy Regulatory Commission (FERC), which oversees the interstate power grid, is looking at ways to encourage utilities to use "grid-enhancing technologies" — tools like dynamic line ratings and advanced power flow controllers that squeeze more capacity out of existing power lines instead of building new ones. FERC Chairman Laura Swett told a Senate committee this week that the agency has formed a task force to study possible incentives. Because these technologies can be cheaper than new transmission lines, wider use of them could help slow the rise in grid costs that eventually show up on electric bills. Right now, utilities actually have a financial incentive to spend more on big infrastructure projects, since that spending is what earns them their profit. Senator Angus King of Maine argued FERC needs to find ways to reward utilities for choosing cheaper upgrades instead, since grid costs are set to climb sharply over the next five to ten years. Separately, FERC is also pushing grid operators to speed up how they connect large new power users, such as data centers, and to consider these same lower-cost technologies before building expensive new transmission. None of this changes anything for homeowners immediately — there's no new rebate or program to apply for. But it's a sign regulators are trying to hold down the grid-related costs that flow into everyone's electric rates, which matters if you're weighing the long-term value of home upgrades like a heat pump or electrical panel work tied to your local utility's rates.
NEVI gets real in Illinois as first federally funded EV chargers go online
Illinois turned on its first EV charging station built with federal highway money this week, at a Phillips 66 gas station in Casey, along Route 49 near Interstate 70. The four fast chargers can deliver up to 350 kilowatts and run on the Electrify America network. The project got $854,641 through the National Electric Vehicle Infrastructure program, a federal fund that pays private companies to add charging along major travel corridors. This is mostly news about road-trip charging rather than home charging, but it points to more coming. The state just announced a third round of funding, $23.5 million, that will pay for 140 new charging plugs at 29 locations, with at least four fast chargers at each site so a car can charge in under 30 minutes. Across all three funding rounds so far, Illinois has lined up more than $67 million for 91 stations, with a goal of 489 public charging plugs once the program is finished. New stations are landing in scattered spots around the state, including Champaign, Cook, Kane, LaSalle, Lee, Sangamon, St. Clair, and Will counties, at libraries, hotels, and local businesses. If you drive an EV or are thinking about buying one, this expands the number of places you can recharge on longer trips, particularly in smaller towns that haven't had fast chargers before. It doesn't change anything about charging equipment at your own house, but it does mean fewer worries about running low on a road trip.
Radon mitigation plan
A homeowner in the Appalachian region of Virginia posted a detailed question online about finishing a do-it-yourself radon mitigation project on a 1940s house with a dug-out basement and crawl space. Radon is a naturally occurring gas that can build up in basements and crawl spaces; high levels are a health concern, which is why homes get fitted with mitigation systems. This homeowner already runs a dehumidifier in the basement and has installed a radon fan drawing suction from the sump and from two points in the basement, plus one in the crawl space. The crawl space floor is already covered with thick plastic sheeting. The remaining questions are about the basement, which has a concrete floor poured directly over clay with no gravel layer underneath. The homeowner wants to seal plastic sheeting to the basement floor and walls so they no longer need to ventilate the basement in cold weather just to keep radon levels down, since that ventilation raises heating costs. Open questions include how to attach the plastic to brick walls, how high up the wall it should run, whether a drainage layer or perforated pipe is needed under the plastic to help the fan pull radon out evenly, and whether foam insulation should go above or below the plastic. This is a specific do-it-yourself project rather than a product, program, or rebate announcement, so there is no broader news here for other homeowners. Anyone dealing with radon in an older home with a dirt or unvented basement may recognize similar tradeoffs between sealing, ventilation, and heating costs.
Forgoing College, Top Graduate Builds Career in Sheet Metal
This is a workforce story rather than an upgrade or rebate announcement, but it touches on where the skilled labor behind home HVAC and sheet metal work comes from. Tobias Romero, a top graduate of Valley High School in Albuquerque, New Mexico, turned down college scholarships, including a full ride, to join SMART Sheet Metal Workers Local Union 49. He is starting an apprenticeship as a detailer with signatory contractor Yearout Mechanical, working in sheet metal design and planning rather than only field installation, while taking college courses online and earning a paycheck instead of taking on student debt. Romero came up through Valley High School's Engineering the Future program, which teaches CAD (computer-aided design) and metalworking, and he entered the apprenticeship with advanced credit because of that training. He was one of nine Valley students who signed letters of intent with Local 49 contractors that day, including Yearout Mechanical, JB Henderson, and Butler Sheet Metal & Mechanical. For homeowners, this doesn't change any rebate or program, but it's a small window into the pipeline of skilled workers, including sheet metal detailers and installers, who plan and build the ductwork and equipment layouts behind heating, cooling, and ventilation upgrades in houses like yours.
PEAK Coalition urges New Jersey to mandate battery storage at gas peaker plant
A group of environmental justice organizations is pushing New Jersey regulators to require battery storage at the Bayonne Energy Center, a gas "peaker" plant (one that runs mainly during high-demand periods) that helps power New York City. The coalition, called PEAK Coalition, wants the state's environmental agency to attach that requirement to the plant's operating permit renewal, along with an upgrade of its turbines to a more efficient type. They're asking for at least 65 MW/780 MWh of battery storage, which they say could replace most of the plant's short-term operating runs and cut several types of pollution, including carbon dioxide and nitrogen oxides, by a few percentage points plant-wide. The plant's operator is already building a smaller battery addition of its own, 50 MW/200 MWh, that has been working through state and local approvals since 2023. But the coalition says that project falls well short of what they're requesting. Part of their argument rests on New Jersey's Environmental Justice Law, which they say gives regulators the authority to weigh the pollution burden already carried by the community around the plant. This fight is playing out against a bigger backdrop: New Jersey's governor recently ordered the state to pursue up to 750 MW of battery storage statewide, partly to address rising electricity costs. None of this changes anything for homeowners right now, but it's a sign that battery storage is becoming a bigger part of how the state plans to handle power demand and pricing in the years ahead.
Enervenue unveils 150 kWh nickel-hydrogen battery
A company called EnerVenue has introduced a new large battery system called the Energy Rack, built for utility and commercial-scale energy storage rather than home use. Each unit stores 150 kWh of power and is designed to last 20 to 30 years, with a rated lifespan of 30,000 charge cycles. That's much longer than typical lithium-ion batteries, which usually last around 4,000 cycles. The battery uses a different chemistry than the lithium-ion batteries found in most home solar setups. It's based on nickel-hydrogen technology originally developed by NASA, using a water-based electrolyte instead of lithium. The company says this design lowers fire risk and reduces the need for extensive cooling or fire-suppression equipment. Testing under a safety standard called UL 9540A reportedly showed no risk of thermal runaway, the failure mode that can cause lithium-ion batteries to catch fire. The materials include steel, nickel, and glass-fiber composite, and the nickel can be recovered and reused when the battery reaches the end of its life. This isn't a product homeowners would install directly — it's aimed at large-scale projects, like utility or commercial storage installations, not residential battery backup systems. But the technology is worth watching. If nickel-hydrogen batteries prove cheaper and safer over time, similar chemistry could eventually influence the broader battery storage market, including products designed for homes.
Illinois Shines publishes 2025-26 mentorship program report
Illinois Shines, the state's solar incentive program, has released a report on its mentorship program for small and historically underserved solar businesses. The program, run by the Illinois Power Agency and Energy Solutions, helps contractors who are newly certified for the program learn how to actually submit and get projects approved, since the rules and paperwork can be a lot to sort through. This mostly affects contractors, not homeowners directly, but it points to more solar installers becoming available across Illinois. In the 2025-26 year, two training cohorts ran online over eight weeks each, with a fall group of 20 mentees and a winter group of 17, mentored by representatives from 11 existing Illinois Shines participants. Training covered how to apply, submit paperwork, follow wage and consumer-protection rules, and work with subcontractors. Since the program started in 2023, graduates have gone on to submit more than 335 solar project applications and complete 180 projects around the state. If you're considering solar for your home, this news is a sign that Illinois has been actively growing its pool of trained, small and local installers, including minority-, women-, veteran-, and disability-owned businesses. A related webinar also covered financing options for installers, which may eventually translate into more financing choices offered to customers. The next mentorship cohorts open for registration in August and November, so more newly trained installers should be entering the market this coming year.
DOE’s new power export rule at odds with ‘energy emergency’ findings: Public Citizen
This is a story about federal energy policy, not something that changes your utility bill or upgrade plans directly, but it's worth knowing about if you're watching electricity supply and grid reliability news. The U.S. Department of Energy has been issuing emergency orders since May 2025 to keep certain power plants running past their planned retirement dates, arguing the country faces regional "energy emergencies" with inadequate power supply. One example is the coal-fired Centralia plant in Washington state, ordered to stay open past its Dec. 31 shutdown date. At the same time, the DOE finalized a rule on June 22 that makes it easier for companies to get approval to export U.S. electricity abroad, including to Canada, by cutting back on public reporting requirements and limiting who can formally challenge these export applications. The consumer group Public Citizen says these two positions contradict each other: if supply is tight enough to justify forcing power plants to keep running, it doesn't make sense to also streamline approvals for sending power out of the country. The group filed a request Wednesday asking the DOE to reconsider the export rule, and says it will likely sue if that request is denied. For homeowners, this is a policy dispute happening at the federal level over grid supply and export rules. It doesn't change any rebate program or energy-efficiency incentive, but it's part of the broader debate over whether the U.S. has enough electricity to go around.
Ford’s $30,000 electric pickup will have Apple Maps built in with EV routing and more
This is car news rather than home energy news, but here's what it covers: Ford and Apple announced a partnership to build Apple Maps directly into Ford's upcoming electric vehicles. Starting with a midsize electric pickup coming in 2027, Ford's new electric models will use Apple Maps for turn-by-turn directions, along with routing built for electric vehicles and battery preconditioning (warming or cooling the battery ahead of charging for better performance). This runs on Ford's new "Universal Electric Vehicle" platform. Ford also plans to use Apple's map data to improve BlueCruise, its hands-free highway driving system, aiming for smoother handling of highway entrances and exits. That work is being done by Ford's in-house self-driving team, Latitude AI. The pickup itself is expected to cost around $30,000, with Ford CEO Jim Farley describing it as a simple, affordable option meant to reach more buyers. Prototypes have already been spotted in testing ahead of the 2027 launch. For homeowners, this doesn't affect rebates, electrical panel needs, or home charging setups directly — it's about in-car navigation and software, not the equipment you'd install at home. If you're considering an electric vehicle and thinking about home charging, the relevant details to watch for are things like charging speed, battery size, and any home-charger requirements, which haven't been detailed here.
Sustainability tools to use in 2026
This roundup covers new digital tools aimed at corporate sustainability teams, carbon accounting firms, and large businesses tracking emissions, supply chains, and climate regulations. It's built for professionals managing company-level climate reporting and carbon markets, not for individual homeowners. None of the tools relate to home energy upgrades, weatherization, heat pumps, or residential rebate programs. The closest item to real estate is a new California dashboard from the U.S. Green Building Council that tracks energy and water use across commercial and multifamily buildings statewide, but it's designed for property managers and building owners, not single-family homeowners, and doesn't offer rebates or upgrade guidance. The rest of the list includes things like AI tools for corporate carbon-tax estimates, contract templates for climate-related legal language, marketplaces for carbon credits, frameworks for tracking deforestation in supply chains, and software for companies filing sustainability reports under European Union rules. There's also a Google playbook on using AI for corporate sustainability reporting and a directory of certified experts in corporate emissions target-setting. If you're deciding whether to invest in an energy-efficiency upgrade for your own house, this news doesn't change anything for you. It's aimed at corporate sustainability departments, consultants, and financial teams working on company-wide climate strategy, not at what rebates, financing, or contractors are available for a home retrofit.
Raised by the Sheet Metal Trade, Ready to Lead
This is a profile of MacQuaid Brennan, a 27-year-old sheet metal worker in Montana who recently became training coordinator for the Montana Sheet Metal Workers Joint Apprenticeship Training Committee in Butte. She's the first woman to graduate from the state's apprenticeship program and comes from a family that owns a heating and cooling contracting business. There's no direct action for homeowners here, but it touches on the workforce behind the HVAC and sheet metal trade that installs and services home heating and cooling systems. The piece describes how she moved from studying psychology in college to joining the union apprenticeship in 2020, drawn by steady pay and benefits without college debt. She now teaches Fire Life Safety classes, covering skills for handling fire and smoke dampers in buildings, and has pushed pass rates from around 50 percent up to 15 of 16 students in her most recent class. The apprenticeship program she now leads has 80 apprentices, and the local union has about 600 members and 20 signatory contractors doing HVAC, residential, architectural, and service work across Montana. For homeowners, the takeaway is indirect: programs like this are training the technicians who install and repair heating and cooling equipment, including the heat pumps and other systems tied to home energy upgrades. Brennan's stated goals include updating training facilities and strengthening the curriculum, which could shape the skills of technicians working on homes in the state going forward.
Meta signs PPA for 172 MW of Louisiana solar
Meta has signed a long-term deal to buy power from a new 172-megawatt solar project called Mowata Solar, being built in Acadia Parish, Louisiana. The deal is a power purchase agreement, or PPA, meaning Meta commits to buying the electricity the project generates over many years. The project is being developed by Lightsource bp, which has worked with Meta before on a similar solar project in Ohio. Construction is set to begin later this year and is expected to create 250 to 350 jobs, with Lightsource bp investing $237 million in the project. This is not a program homeowners can sign up for. It adds new solar generation to the regional grid in Louisiana rather than offering rebates or incentives for home upgrades. Deals like this can matter to homeowners indirectly, since more generation added to a local grid can affect electricity supply and, over time, prices and reliability in that area. Lightsource bp has also made community commitments tied to the project, including a $400,000 contribution to the Acadia Parish Industrial Development Board for local education and infrastructure, and a land management plan to restore native prairie habitat on the site. None of this changes what's available to homeowners looking into solar panels, heat pumps, or weatherization work on their own homes — it is a corporate energy purchase, not a residential program.
Tesla Climbs Back Above 50% Share of US EV Market — Who’s in 2nd, 3rd, 4th?
New sales figures show Tesla back above 50% of the US electric vehicle market last quarter, after a stretch below that mark. This isn't because Tesla sold more cars — its sales actually fell 13% compared with a year earlier. It just fell less than the rest of the market, where sales of non-Tesla EVs dropped 27%. Overall EV sales did tick up compared with the previous two quarters, though the market remains small next to gas-powered vehicles. Behind Tesla, the next closest brands were Chevrolet and Hyundai, each with about 5.8% of EV sales, followed by Cadillac at 5.1%, Toyota at 4.8%, and Rivian at 4.6%. Looking at parent companies rather than individual brands, General Motors placed second with 12.7% of the market, combining Chevrolet, Cadillac, and GMC sales. Hyundai-Kia came in third at 8.9%, Toyota Motor Co. fourth at 6.1%, and Rivian fifth at 4.6%. For homeowners weighing an EV alongside other home energy upgrades like solar or a heat pump, the practical takeaway is that Tesla still dominates, but mainstream brands like Chevrolet, Hyundai, and Toyota are also selling in real numbers, meaning more models and more dealer familiarity outside the Tesla ecosystem. If you're shopping for a home charger or comparing an EV's fit with rooftop solar, it's worth knowing that the market remains lopsided toward one manufacturer, which can affect things like charging standards and available incentives tied to specific brands.
Sustainability pays a credibility tax. Some of it is self-imposed
This is a business and corporate strategy story, not something that affects your home or energy upgrade plans directly. It looks at how sustainability leaders inside companies are treated compared to other executives, like the chief financial officer or chief legal officer. The piece cites a survey of more than three dozen sustainability leaders: only 5 percent said their funding requests get treated the same as requests from finance or operations, while 55 percent said their proposals are seen as "nice to have" rather than necessary. A separate check of 200 major global companies found that all of them listed their CFO on their public "About Us" page, and 85 percent listed their chief legal officer, but only 14 percent listed their head of sustainability. A survey of corporate communications officers found just a quarter thought their own executives believed climate action was in the company's best interest. The author argues part of this credibility gap is self-inflicted, pointing to habits like citing survey answers about what people say they'd do as if that proves what they actually buy, downplaying the value of the sustainability role itself, using vague language instead of specific numbers, and claiming sustainability's financial benefits can't be measured. None of this changes what rebates or upgrades are available to homeowners. It's a look at how sustainability work is valued and funded inside large companies.
Brookfield to buy energy storage developer Aypa for $7 billion
Brookfield Asset Management is buying solar and battery storage developer Aypa Power from Blackstone in a deal worth about $7 billion, valuing the company at $3 billion. Aypa builds large-scale battery storage systems (BESS) — big installations that store electricity, often paired with solar or wind, to help the grid handle demand more reliably. The company has 12 projects totaling 2.1 gigawatts underway across eight states, including Texas, California, and Louisiana, and describes itself as one of the largest standalone battery platforms in North America, with 6.5 gigawatts of projects operating, under construction, or contracted, plus another 20 gigawatts planned for the future. For homeowners, this deal itself doesn't change anything about your house directly — it's a corporate ownership change in the utility-scale power business, not a residential program. But it's a sign of how much money is flowing into large battery storage, which utilities increasingly rely on to keep the grid stable as more solar and wind come online. More grid-scale storage in your region can mean fewer strains during peak demand and potentially more support for programs that reward homes with solar panels or batteries for feeding power back to the grid. Brookfield already owns stakes in other big renewable energy companies, including Deriva Energy (formerly Duke Energy Renewables), Scout Clean Energy, and Standard Solar. This purchase adds another major storage developer to its portfolio as it expands further into the battery storage business.
Brookfield acquires Aypa Power in $7 billion energy storage deal
Brookfield Asset Management is buying battery storage developer Aypa Power from Blackstone in a deal valued at about $7 billion. Aypa builds and operates large batteries that store electricity, mostly for the power grid, in the United States and Canada. It has 6.5 gigawatts of storage that's already running, under construction, or under contract, plus a much bigger pipeline of over 20 gigawatts in more than 70 planned projects. Most of its existing and in-progress projects are locked into long-term contracts, averaging 17 years, with large, financially stable buyers. For a homeowner, this deal itself doesn't change anything about your house or your utility bill directly. It's a corporate transaction between two large investment firms, not a new program or rebate. But it points to continued heavy investment in grid-scale battery storage across North America, which matters because more storage capacity can help make the electric grid more reliable and better able to handle power from wind and solar. Over time, a stronger, more flexible grid can mean fewer outages and potentially more stable electricity prices in the areas these projects serve. There's no action for homeowners to take here. This is industry news about who owns and develops large battery projects, not a new incentive or upgrade option for your home. If you're weighing your own energy upgrades, like a heat pump or home battery, it's worth checking what programs or rebates are currently available in your state, since those are separate from deals like this one.
Detached garage HVAC
A homeowner is renovating the second floor of a detached, two-story garage into a roughly 600-square-foot office and exercise space, split into two rooms. The project involves removing the existing truss structure and adding a structural ridge beam, replacing all windows, and improving insulation throughout: R-20 batts under the gambrel roof sides, R-13/R-5 on the side walls, and either closed-cell spray foam or rigid foam board for the roof deck. Three skylights and new siding are also part of the plan. The current heating and cooling system, an 18,000 BTU ductless mini-split (a compact heat pump that sends warm or cool air through a wall-mounted unit rather than ducts), has not worked well, and the two rooms end up at noticeably different temperatures during hot or cold weather. The homeowner is weighing two replacement options: separate ductless mini-split heads for each room, sized around 6,000 and 9,000 BTU given the planned insulation upgrades, or a single ducted mini-split system with duct runs built into floor chases. They're also considering adding a wall-mounted energy recovery ventilator (a device that brings in fresh air while recovering heat from the air being exhausted) to the mix. Separately, the homeowner is looking for a roof material for the garage that can handle regular impacts from a basketball hoop mounted on the building, without shedding granules onto the sport court below, while still being practical to install on the gambrel roof's angles.
Deliveries, automation, and the gateway drug to electrification with BIG JOE
This one is not really about home energy upgrades. It is a podcast episode about electric forklifts, a category of equipment used in warehouses and factories rather than houses. The guest, from a forklift maker called Big Joe, talks about battery-powered and self-driving forklifts that are quieter and cleaner than the diesel or propane models they replace, since indoor spaces cannot handle exhaust from gas engines. There is no news here that touches your own home directly. No rebate program, no appliance, no state policy, no deadline. It is really a look at how electrification is moving into industrial equipment, forklifts included, as one more sign that battery power is spreading beyond cars and trucks into other kinds of machines. If you are weighing upgrades like a heat pump, induction stove, or better insulation and air sealing (blocking drafts and gaps that leak heated or cooled air), this piece will not change your plans one way or another. It is more a snapshot of the broader electric-equipment industry than something with dollar figures, dates, or eligibility rules a homeowner could act on.
Nominations for Annual Women in HVACR Awards
This is industry news with no direct impact on homeowners or their heating and cooling systems. Women in HVACR, a nonprofit supporting women who work in the heating, ventilation, air conditioning and refrigeration (HVACR) trades, is taking nominations for two award programs: the Pillar Awards and the Women to Watch recognition. Nominations are open through August 10, and nominees must be active members of the organization. The Pillar Awards will go to three members for excellence in mentorship, education, or building professional networks within the industry. The Women to Watch program will recognize women in five areas: technician leadership, manufacturer leadership, vendor and distribution leadership, office and operations leadership, and advocacy. Winners will be announced at the group's annual conference, called Built for Speed, running September 27 through 29 at the JW Marriott in Indianapolis. For a homeowner, this doesn't change anything about your heating or cooling system, your bills, or available rebates. It's simply a trade association recognizing people who work in the field that installs and services the equipment in your home, such as furnaces, air conditioners, and heat pumps. If you're curious about the broader HVACR workforce or industry trends, this points to the kind of organizations that support technicians and other professionals, but it has no bearing on any upgrade or repair decisions for your own house.
Tesla swapped a solar owner’s lease contract for the Book of Enoch
A Tesla solar customer recently logged into their account to check the terms of their solar lease and found the document had been replaced with the full text of the Book of Enoch, an ancient religious text about fallen angels. It wasn't a scanning error or blank page — the actual lease agreement, which spells out payment terms and what happens if you want to end the contract early, was simply gone. Tesla support confirmed the swap in a chat conversation but couldn't explain how it happened. The company apologized and emailed the customer a correct copy. No one knows exactly why this happened. It could be a mishap involving Tesla's back-end systems or AI tools that manage customer files, a mislabeled placeholder document that leaked into a live account, or a simple technical error. Tesla hasn't said. For homeowners, the bigger issue isn't the odd substitute text itself but what it says about how carefully Tesla handles lease paperwork. A solar lease is a binding contract that matters especially if you sell your house later, since a buyer may need to take over the lease. This comes as Tesla is trying to rebuild trust in its home solar business after bringing back leasing in late 2025, following its earlier retreat from solar subscriptions. If you have a Tesla solar lease, it may be worth pulling up your own copy in your account to make sure it's actually your contract and not something stranger.
Europe Can Unlock 25 GW of Clean Power by Using Existing Grid Connections
A new report from the energy think tank Ember finds that Europe could add 25 gigawatts of wind and solar power without building any new grid connections, by pairing these projects with existing hydropower plants. The approach, called hybridization, combines two or more power sources, like hydropower and solar, at the same grid connection point, since hydropower plants typically use only part of their available grid capacity during the day. Adding wind or solar at those same connection points can roughly double how much of that capacity gets used, without exceeding existing export limits. The report looked at seven countries with major hydropower resources: Austria, Bulgaria, France, Italy, Portugal, Romania, and Spain. It found that hybridization could deliver 18% of the new renewable power these countries expect to add by 2030, without requiring any additional grid buildout. Right now, only Portugal and Spain have specific rules in place for hybrid projects, while the other five countries lack a clear regulatory framework for them. This story is about European grid policy, not something that changes what's available to homeowners directly. But it points to a broader trend worth knowing about: as grid capacity becomes a bottleneck for adding clean power, using existing connections more efficiently is becoming a bigger part of how utilities and regulators plan to speed up the shift to renewables. If more clean power comes online faster and cheaper this way, it could eventually show up as steadier or lower-cost electricity, though the report does not spell out timing or effects on consumer bills.
Could a new iron ore mine turn Minnesota into a green steel powerhouse?
A new iron mine on Minnesota's Iron Range, developed by Essar Group under the name Mesabi Metallics, is set to start producing iron pellets this fall after its first blast in July. The $2.5 billion project, near Nashwauk, will be the region's first new mine in 50 years and is designed to make a cleaner type of iron pellet suited for "direct reduction," a lower-carbon way of turning iron ore into iron for steelmaking, compared with traditional coal-fired blast furnaces. The company says it will use electrified and diesel-electric equipment to cut energy use during mining and processing. This matters mostly as industry and regional news rather than something that changes what's available to homeowners today. The broader shift it's part of, toward direct-reduced iron paired with electric arc furnaces instead of coal-based blast furnaces, could eventually mean lower-carbon steel used in appliances, cars, and building materials. But that transition is moving slowly, and no consumer programs or rebates are tied to it. Other Minnesota entrepreneurs are pursuing similar plans to reprocess old mine waste into iron for out-of-state steel plants, and researchers at the University of Minnesota are testing new methods, including hydrogen-based ironmaking and a coal substitute made from fast-growing poplar trees. For now, this is a story about jobs, mining technology, and the future of heavy industry in northern Minnesota. There's no rebate, incentive, or home-upgrade angle here for homeowners to act on. The bigger picture, if the shift toward cleaner steelmaking continues, is that some of the materials used in future construction and manufacturing could carry a smaller carbon footprint.
GE Vernova gas turbine backlog climbs to 116 GW
Power equipment maker GE Vernova reported strong demand for large gas turbines and electrical gear like transformers, the kind of heavy machinery utilities use to build and run power plants and grids. The company's order backlog for gas turbines climbed to 116 gigawatts, up from 100 gigawatts a few months earlier, with utilities and data center operators both placing orders years in advance. Its electrical equipment business also grew fast, with a backlog topping $40 billion, driven partly by demand tied to data centers and rising electricity use nationwide. For homeowners, this is mostly a signal about where the broader grid is headed rather than something with a direct, immediate effect on your house. Heavy orders for gas turbines and grid equipment point to utilities expecting significant growth in electricity demand in the coming years, partly from data centers. That kind of demand growth can influence how utilities plan investments, which over time can affect electricity rates and how much capacity is available on the grid. The company's wind turbine business, by contrast, is struggling, with orders down sharply due to tariff uncertainty and weak U.S. demand for onshore wind. Analysts see some hope for a rebound tied to aging wind farms being rebuilt with newer equipment. None of this changes anything about home energy upgrades or rebates directly, but it offers a broader picture of how the power industry is positioning itself for the years ahead.
Even Under Extreme Warming, ASEAN’s Wind & Solar Generation Variation From Normal Will Be Less Than 1% In 2030
A new report on Southeast Asia's power grid offers a useful data point for anyone weighing solar or battery storage at home: distributed renewable energy holds up far better under extreme weather than large, centralized fossil fuel plants. The report, from energy think tank Ember, looked at the ASEAN region, where about 64% of power capacity still comes from fossil fuels. It found that even under the most extreme warming scenarios projected for 2030, wind and solar output would vary by less than 1% from normal levels, a much smaller swing than the losses expected at fossil fuel and nuclear plants even under milder warming. The reasoning: rooftop solar, wind, and battery systems spread generation across many small sites instead of concentrating it in one large plant. When a storm, earthquake, or other disaster hits, damage stays localized and can be repaired faster, rather than knocking out power for an entire region at once. The report cites real examples, including a 2018 earthquake in Indonesia that disabled a coal plant and damaged over a thousand distribution units, and repeated typhoon outages in a diesel-dependent Philippine province. None of this changes rebate programs or equipment choices available to homeowners elsewhere, but it reinforces a point relevant to anyone considering solar panels or a home battery: these systems are not just about lowering bills or emissions. They also tend to keep working, or come back online faster, when the broader grid takes a hit.
SC judge determines solar manufacturing needs ‘heavy industrial’ zoning Silfab Solar can continue work in 'light industrial' zone due to prior approval.
A South Carolina judge has ruled that solar panel manufacturing counts as heavy industrial activity, not the lighter "computer and electronic products manufacturing" category that York County had used to approve Silfab Solar's plant in Fort Mill. The York County Board of Zoning Appeals had already reversed itself on this back in 2024, and the judge's ruling this week backs that reversal. This doesn't shut down Silfab's plant. Because the project was already underway before the zoning board changed its position, the company is grandfathered in and can keep operating in the light industrial zone where it's located. Silfab says the ruling has no effect on current operations or permits, and employees are working as normal. The company plans to appeal, mainly to protect its ability to expand production and hiring at the site in the future. Some Fort Mill residents have opposed the plant, citing its location near an elementary school and concerns over chemicals used in solar cell manufacturing, concerns that grew after two chemical spill incidents in March, though state and federal environmental regulators said there was no risk. For homeowners, this is mostly a local zoning and manufacturing story rather than something that changes solar costs or incentives directly. Silfab's Fort Mill site is meant to produce panels and cells domestically, which could matter over time for the supply and pricing of US-made solar equipment, but nothing here affects rebates or installation options right now.
The deadly experiment that could save the American elm
Researchers in Vermont are deliberately infecting thousands of young American elms with Dutch elm disease, the fungus that has killed tens of millions of elms since it arrived in North America last century. The goal is to find the rare trees that can survive repeated exposure, then breed them into a new, genetically diverse population that could eventually repopulate river valleys and floodplains across the country. American elms once lined Main Streets nationwide before the disease wiped most of them out. Past breeding efforts produced a few disease-tolerant varieties sold in nurseries, but they came from a narrow gene pool and aren't tough enough for the harsh, repeated exposure trees face in the wild over long lifespans. This new project pulled cuttings from dozens of surviving "parent" trees around New England, cross-bred them, and is now testing thousands of offspring by injecting them with the fungus directly. Early results, with hundreds of trees showing no symptoms so far, are promising, though researchers won't know which parent trees produced the hardiest offspring for at least two more years, and any resulting seed orchard is still a decade or more away from producing widely available trees. For homeowners, there's no product or program to act on yet. But elms matter beyond looks: they tolerate shade and flooding better than almost any other floodplain tree, and healthier elm populations could help absorb storm water and reduce flood damage in the regions where they once grew. If this research succeeds, more resilient elms could eventually become available for planting on private property, though that's still years off.
Array Technologies expands balance of system platform with $203 million AWM acquisition and new 60 degree solar tracker
This is industry news about utility-scale solar equipment, not something that touches individual homes, but here's what's happening. Array Technologies, which makes solar tracking systems (equipment that tilts solar panels to follow the sun), is buying a company called Affordable Wire Management for up to $203 million. The deal includes $153 million in cash plus up to $50 million more if performance targets are met through 2028. Affordable Wire Management makes cable protection and wiring hardware used in large solar installations, and the purchase also gives Array a foothold in battery storage and data center equipment. The deal is expected to close in the third quarter of 2026. Separately, Array introduced a new version of its DuraTrack tracker system, angled at 60 degrees, aimed at large solar farms in areas with moderate hail risk, such as Texas and the Great Plains. The design lets panels tilt steeply to avoid hail damage while using software that triggers automatic hail alerts. It's built with wired power and communication lines rather than wireless or battery-based controls, and includes wind-sensing technology that reduces panel movement during storms, which the company says can boost energy output by up to 4% compared to older stow designs. Array plans to start taking orders for this new tracker in 2026, with first deliveries expected by mid-2027. None of this affects rooftop solar or home energy equipment. It concerns hardware for large, utility-scale solar farms.
Tesla (TSLA) crashes 12%, sheds $140B as Elon Musk’s ‘just trust me’ doesn’t hold anymore
Tesla stock dropped more than 12% today, losing over $140 billion in value, after the company's second-quarter earnings missed profit expectations and free cash flow turned negative for the first time in years. Revenue and deliveries hit records, but profit collapsed as spending jumped and a key revenue source, regulatory credits, fell 67%. Tesla also leaned on cheap financing deals to move cars, which cut into profit margins. The stock fell further during the earnings call, when Elon Musk repeated familiar claims about the company's Optimus robot and its robotaxi self-driving service. Tesla reported 380,000 "unsupervised" miles across six cities, but that figure is small next to competitors, and the company's own data shows growth has stalled: paid robotaxi miles were flat compared to the prior quarter, and the number of active cars in the service has actually been shrinking even as Tesla adds new cities. For homeowners, this is mainly a story about Tesla's stock and business strategy rather than anything that changes home energy costs or rebates. It doesn't affect EV incentives, solar programs, or home battery pricing directly. Tesla's energy storage business, which includes home batteries, did grow, with deployments up 41%, though margins there also slipped. The bigger picture is that investors are losing patience with Tesla's self-driving and robotics promises after years of missed deadlines.
1973: Arab Oil Embargo Popularizes Programmable Thermostats
This is a look back at how the programmable thermostat came to be. Before 1973, energy was cheap and many homes, especially in the Northeast, ran on heating oil delivered by truck. When the Arab Oil Embargo hit that year, oil prices quadrupled and utility bills jumped fast. President Nixon responded by asking Americans to turn thermostats down at least 6 degrees, aiming for an average daytime indoor temperature of 68°F, and asked workplaces to cut back 10 degrees. A few years later, President Carter pushed the recommended winter setting down further, to 65°F. The catch was that thermostats back then had to be adjusted by hand. Getting people to remember to turn the dial down every night or before leaving for work didn't work well in practice. That gap led manufacturers to build thermostats with mechanical clocks inside, so a household could schedule a temperature drop overnight or during the day automatically. That shift turned the thermostat from a simple dial into an energy-saving tool, and set the stage for the programmable and smart thermostats sold today. For anyone with an older, manual thermostat still on the wall, this bit of history is a reminder of why programmable and smart models exist in the first place: they took the guesswork and forgetfulness out of turning the heat down, a problem homeowners have been dealing with since the 1970s energy crisis.
Environmental Groups Sue to Stop Discharge of Toxic Metals from Coal Ash
Three environmental groups — the Iowa Environmental Council, the Environmental Law and Policy Center, and Sierra Club — have sued the Iowa Department of Natural Resources over permits for the coal ash landfill at the Ottumwa power plant, co-owned by Alliant Energy and MidAmerican Energy. Coal ash is leftover waste from burning coal, and it contains toxic metals like arsenic, mercury, and lead that can cause cancer and other health problems. The lawsuit says the DNR's permits let the plant keep discharging "leachate" — rainwater that seeps through the ash and picks up these metals — into groundwater and waterways without any deadline for stopping it, even though federal rules from 2024 require facilities to end this discharge "as soon as possible." The suit also challenges the plant's release of groundwater already polluted with heavy metals. The groups argue Alliant looked at ways to treat the contamination but only addressed iron, not the other toxic metals, and is currently trucking waste to the city's wastewater treatment plant instead of building proper treatment. They're asking the court to force the DNR to require Alliant to stop the pollution. This case is specific to Ottumwa, Iowa, but it points to a broader issue: coal ash storage sites across the country can leach toxic metals into local water supplies if not properly managed. If you live near a coal ash site or get water from a system that could be affected by one, this is the kind of local environmental and legal fight worth keeping an eye on, since it may shape how such sites are regulated going forward.
1.2-GW solar project to tie into existing 300-MW coal plant in Texas
A large solar project is being built in Texas, midway between Dallas and Houston, on land that also hosts a working coal plant. The $1.7 billion Big Rooter Power project will add 1.2 gigawatts of solar generation, built in two phases: Big Rooter West (491 megawatts), expected online in August 2028, and Big Rooter East (658 megawatts), starting construction next year and expected online in August 2029. The site, called Twin Oaks, will keep running its existing 310-megawatt coal-fired plant alongside the new solar — there's no plan to retire it. Once finished, the Twin Oaks complex will have 1.5 gigawatts of combined coal and solar power, plus 20 miles of new high-voltage transmission lines, large-scale battery storage (1.6 gigawatt-hours), and data center capacity being developed on the same 10,000-acre site. The project is expected to create over 800 construction jobs. For homeowners, this isn't a program you can sign up for or a rebate to chase — it's a utility-scale build that adds power supply to the Texas grid rather than a home energy upgrade. It's worth knowing about mainly as a sign of how much new solar and battery capacity is being added in Texas, often alongside existing fossil fuel plants rather than replacing them, which can affect regional electricity supply and pricing over time.
The year climate change came for the Tour de France
This year's Tour de France, the famous three-week bike race across France, ran into a problem that has nothing to do with cycling strategy: heat and wildfires. The first two weeks brought an average temperature of 90 degrees Fahrenheit, the hottest stretch in the race's past two decades of data, and wildfires in the Pyrénées-Orientales region forced organizers to limit the crowds and vehicles following one stage. Riders described headaches and exhaustion, teams handed out roughly 28 water bottles a day per rider, and many wore ice-packed vests before and during races. For the first time in the Tour's history, organizers shortened a stage because of the heat, cutting nearly 19 miles from one leg, and French officials gave regional authorities the power to cancel stages entirely during a red heat alert. None of this changes anything about home energy upgrades directly, but it's a vivid example of how extreme heat is showing up in daily life, not just in forecasts. Nighttime temperatures that stay high mean less recovery time for bodies, whether that's a professional athlete or someone at home without reliable cooling. That's the same dynamic driving interest in home weatherization and heat pumps here — sealing up a house and having efficient cooling matters more as heat waves get longer and more intense, even far from a bike race in France.

Nighttime temperatures that stay high mean less recovery time for bodies, whether that's a professional athlete or someone at home without reliable cooling. That's the same dynamic driving interest in home weatherization and heat pumps here — sealing up a house and having efficient cooling matters more as heat waves get longer and more intense, even far from a bike race in France.
