Pssst, Hey There Elon Musk! Twitter Is Coming Back
This is a story about a social media trademark dispute, not an energy-efficiency topic, so it doesn't affect any home upgrade plans or rebate programs. Still, here's what happened: after Elon Musk bought Twitter in 2022 and rebranded it as X, a startup called Operation Bluebird, led by Twitter's former general counsel Stephen Coates, argued that X Corporation had abandoned the "Twitter" trademark by dropping the name and the bird logo. Operation Bluebird petitioned the U.S. Patent and Trademark Office to cancel X's trademarks so it could relaunch a new platform called Twitter Now. X fought back in court, but in April a federal judge in Delaware indicated from the bench that X may have given up its rights to "tweet," the bird logo, and possibly the Twitter name itself. No formal written ruling has been issued, so the trademark question remains unsettled. Despite that, Coates announced last week that Twitter Now had launched, describing it as a new platform built around trust and transparency rather than an algorithm-driven feed. As of this writing, the site was showing a maintenance message, though a related site was still collecting signups from people interested in early access. None of this has any bearing on home energy upgrades, rebates, or equipment. It's simply a legal and tech industry dispute over who gets to use the Twitter name.
Tesla FSD can soon avoid potholes, says Elon Musk who said exactly that in 2019
This is a car news story, not an energy-efficiency topic, so it has little direct bearing on home upgrades or rebates. Briefly: Tesla CEO Elon Musk said over the weekend that Full Self-Driving (FSD), Tesla's driver-assist software, will "soon" be able to spot and avoid potholes. He made the same promise back in 2019, and it never arrived. Tesla's software has improved over the years and can now handle highways, city streets, and even parking, but it still hasn't solved the pothole problem, despite the company saying for years that it scans roads for them. The timing matters because Tesla is about to launch its "Cybercab," a fully driverless robotaxi with no steering wheel, in a limited service area later this week. If the cars still can't avoid road damage, that raises questions about wheel and tire damage or safety issues for vehicles operating without anyone behind the wheel to react. None of this affects home energy upgrades, rebates, or weatherization programs. If you're considering an EV charger or solar setup for your house, this story doesn't change anything about incentives or technology available to you — it's simply an update on the state of Tesla's self-driving software and Musk's track record of predicting features that take much longer than promised to arrive, if they arrive at all.
Segway ZT3 Pro e-scooter $850, Anker SOLIX 2,010Wh power station $549 off, EGO Nexus 2x battery bundle rare discount, more
A few deals worth a look this week if you're thinking about backup power or outdoor equipment for your home. Amazon's Labor Day sale includes a 2,010Wh Anker SOLIX S2000 portable power station, marked down $549 to $650. Portable power stations like this can run appliances or keep essentials going during an outage, without the installation that comes with a whole-home battery system. There's also a rare discount on EGO's 3,000W Nexus Portable Power Station bundle, which comes with two 7.5Ah batteries, now $899. Power stations built around swappable batteries like these can double as backup for the house or as a power source when you're working outside, since the same batteries often fit EGO's yard tools. Rounding out the list are deals on a Segway ZT3 Pro all-terrain electric scooter for $850, plus discounts on Worx's Aerocart wheelbarrow-style cart and its 2-in-1 chainsaw/pole saw combo. None of these are tied to energy rebates or efficiency programs, but if you're weighing options for emergency backup power or electric yard equipment, the power station discounts are the ones most relevant to your house. As with any sale, check the current price and availability before buying, since deals like these are often time-limited.
Tesla confirms Autopilot/FSD was active in strange fatal crash
Tesla has told federal safety regulators that its driver-assist system, either Autopilot or "Full Self-Driving," was confirmed active in a fatal crash in Clute, Texas, in May 2026. A 2025 Model 3 driven by Steven Alvarez, 23, left the road, crashed through a park fence, and hit a pool complex, catching fire. Tesla's report to the National Highway Traffic Safety Administration (NHTSA) marks the system as "Verified Engaged," meaning the company's own data confirmed it was running, and lists the car's speed just before impact at 104 mph. None of that appeared in local news coverage or police statements, which said officers believed Alvarez may have suffered a medical episode. No speed was mentioned publicly. Tesla redacted the crash narrative, the software version, and whether the road fell within the system's approved operating area, calling that information confidential business information. Because of the redactions, it isn't clear whether Autopilot or "Full Self-Driving" was involved, or what role it played. Possible explanations include the software driving improperly, a reporting error in the speed data, or a medical emergency causing Alvarez to press the accelerator while the system was engaged. This isn't a story with a direct action for your own home or car, but it's a reminder that crash data from these driver-assist systems is largely hidden from the public. Tesla is currently under NHTSA investigation over how it reports crashes involving these systems.
BYD’s electric supercar will beat a Lambo in a race, and it’s cheaper than a Porsche [Video]
This story is about a new electric supercar, not something that touches home energy upgrades or rebates. BYD, the Chinese automaker, has launched the Denza Z, an electric supercar with three electric motors producing about 1,600 horsepower. It can go from 0 to 62 mph in under 2 seconds and reach a top speed of 217 mph. In a test race against a Lamborghini Temerario, the Denza Z won two out of three runs. Pricing starts at £142,900 (about $193,000) in the UK for the base Coupe, rising to £172,900 (about $234,000) for the top Racing trim. That undercuts the Porsche 911 Turbo S, which starts around £199,100 (about $270,000) and is slower to accelerate. In China, prices are roughly half what they are in Europe. The car uses an 800-volt electrical system and BYD's own fast-charging tech, letting its battery go from 10 percent to 70 percent charge in as little as five minutes. None of this relates to home weatherization, heat pumps, or rebate programs. It is simply news about a high-performance electric vehicle aimed at buyers cross-shopping with luxury sports car brands, not a development that affects household energy costs or upgrade planning.
A second Tesla driver died stopped on a freeway with Autopilot/Self-Driving on
This is Tesla and car news, not a home energy story, but here is what happened. A second Tesla driver has died after their car came to a stop in a live freeway lane and was rear-ended, matching a pattern from a similar fatal crash in Florida weeks earlier. This time it happened on Loop 202 near Mesa, Arizona, just after 3 a.m. on October 31, 2025, when a 2020 Model 3 was struck from behind by a Ford F-350 pickup. The Tesla driver died at the scene, and police reports at the time did not mention Autopilot or "Full Self-Driving," Tesla's driver-assist systems. Electrek says it matched the crash to a federal safety filing in which Tesla confirmed its driver-assist system was "Verified Engaged" and that the car was stopped at 0 mph in a travel lane in clear weather. Tesla says it holds the car's event-data recorder, telematics, and video, but it redacted the crash narrative, the software version, and whether the road was approved for the system to operate on, calling that information a trade secret. Both this crash and the earlier Florida one involve the same setup: a 2020 Model 3 with driver-assist engaged, stopped in a freeway lane, then hit from behind. Tesla is already under federal investigation over how it reports crashes involving these systems. This story does not involve home energy programs or rebates.
French Drain Sizing: Corrugated vs. Smooth pipe capacity and the “wedge” stone error
A homeowner forum thread digs into a drainage detail that trips up a lot of yard drainage projects: French drains, the gravel-and-pipe trenches used to route water away from a house. The question centered on how much water these systems can actually carry and how much stone they need. On pipe capacity, the poster pointed out that standard plumbing tables assume smooth-wall pipe. Flexible corrugated pipe, which is bumpier inside, moves water more slowly. At a typical slope, a 4-inch smooth pipe can carry about 113 gallons per minute, while the same size corrugated pipe carries only about 57 gallons per minute — roughly half. If a system was sized using tables meant for smooth pipe but installed with corrugated pipe, it could end up undersized for heavy rain or roof runoff. On stone, the trench has to slope slightly for water to drain, even on flat ground, so it gets deeper as it goes. In one example, a 50-foot trench started 18 inches deep but ended nearly two feet deep. Calculating stone needs based only on the starting depth, rather than the average depth, can shortchange the order by around 17 percent. A contractor who replied on the thread said he avoids corrugated pipe altogether, citing installation and maintenance issues, and suggested measuring trench depth at the midpoint rather than doing precise wedge math, since stone is inexpensive and it is easier to simply order a bit extra. For homeowners planning a French drain around their own house, the takeaway is that pipe type and slope both affect whether the drain works as expected.
HVAC heating efficiency from ceiling mounted registers. Replacing oil fired baseboard heat
A homeowner replaced an aging oil furnace's air conditioning system with high-efficiency, variable-speed HVAC units and now wants to drop the oil furnace entirely, using a propane tank water heater for hot water and the new HVAC system alone for winter heat. The catch: the house has ceiling-mounted registers rather than floor vents, and the current setup relies on oil-fired baseboard heaters for warmth. The owner's spouse worries that heat blown from the ceiling won't keep a one-story, 2,000-square-foot home comfortable in a cold climate (zone 4A covers much of the northern half of the country). Building science experts responding to the question say there's no universal answer, since it depends on how airtight the house is and how far the warm air can "throw" from the ceiling. The main risk is stratification, where warm air pools near the ceiling while cooler air settles near the floor. Fans that stir the air, aiming the registers to push air downward, and adding a return vent near floor level can all help mix the layers. Both experts suggested keeping the old boiler as a backup while testing the new system through a winter, rather than removing it right away. If the HVAC mostly works but struggles on the coldest days, a smaller backup heat source could fill the gap. For anyone with a similar ceiling-register layout who is thinking about dropping a boiler or furnace, the practical lesson is to test before you remove: keep the backup heat source in place for at least one heating season to see how the space actually performs.
Rheem Hybrid Water Heater Exhaust Temperature
A homeowner posted a question in an online building forum about their 65-gallon Rheem hybrid water heater. This type of unit uses a heat pump to pull warmth from surrounding air to heat water, rather than relying only on an electric heating element, which normally saves energy. The owner noticed the unit, now about five years old, has started running constantly in heat pump mode without properly cooling the exhaust air. The exhaust was only a few degrees cooler than the air going in (69 degrees out versus 72 degrees in), when it used to run much cooler. At the same time, daily electricity use jumped from 3-4 kilowatt-hours to 9-13 kilowatt-hours, even after the owner cleaned the unit's filter. No one had answered the post with an explanation or fix at the time it was shared, so there isn't a confirmed cause or solution to report. If you own a similar hybrid water heater, this is worth keeping in mind: a heat pump water heater that suddenly starts running longer while barely cooling the air around it, paired with a sharp rise in electricity use, is a sign something may be wrong with the heat pump portion of the system rather than normal wear. Since the unit reviewed here is five years old, it's a reminder that even efficient equipment can develop problems that quietly erase the energy savings it was bought for, so unusual jumps in your own utility bills are worth noticing.
Greenheck Redesigns Ventilators With Contractors in Mind
Greenheck has redesigned its Model CUE roof ventilators, the fan units mounted on roofs to exhaust air from a building. These are commercial and industrial-grade fans, not typical residential equipment, so this news mainly affects buildings like restaurants or larger properties rather than a standard single-family home. The changes focus on making the fans easier to install and service. A new adjustable mounting base lets installers fit the fan to different roof openings without needing extra adapter parts, whether replacing an old unit or setting up new ductwork. A new wiring option keeps low-voltage control wires separated from high-voltage power wires, which building codes require, without needing extra on-site fabrication. Other updates include a motor unit that can be swapped out faster, a hood cover that pops off with the push of two buttons instead of tools, and a shorter hood profile that gives easier access to the motor and other parts needing service. The ventilators are certified to industry standards for energy use, sound, air performance, and safety, including ratings tied to smoke control and restaurant exhaust systems. For most homeowners, this update has no direct bearing on home energy upgrades or rebates. It is aimed at commercial ventilation projects, where faster installation and simpler repairs can matter for building owners and the people who maintain their systems.
Deleting gable vents when adding a ridge vent
A homeowner in Oregon's Willamette Valley asked a building science forum a question worth knowing if you're ever re-roofing: when you add a ridge vent (a vent running along the peak of the roof) to a garage or attic that already has gable vents (vents in the triangular wall sections at the roof ends) and soffit vents (vents under the roof overhang), do you need to block off the old gable vents? An expert responded that the only real downside of leaving all three vent types open at once is that too many "outlet" vents compared to "inlet" vents can depressurize the attic space, which can pull more air leakage up through the ceiling from the rooms below. That matters in a heated, occupied attic, since it can waste energy and drag conditioned air out of your living space. But in a garage that's rarely heated, as in this case, that concern mostly disappears, so there's little reason to seal up the gable vents. The practical point for anyone planning similar roof work: adding a ridge vent doesn't automatically mean you have to close existing gable vents. The tradeoff mainly applies to insulated, heated spaces where losing warm air through the ceiling costs you money. For an unheated garage or similar space, it's fine to leave the old vents in place alongside the new ridge vent, keeping installation simpler without a meaningful downside.
Stranded Asset, What Happens When A Gas Car Becomes Worth Less Than Zero As Transportation?
A CleanTechnica writer is making a five-year bet: by around 2031, ordinary used gas and diesel cars in the US could become "worth less than zero" as transportation, meaning it costs more to keep fueling and repairing them than they're worth once cheap used electric vehicles (EVs) are widely available as an alternative. He points to Norway, where EVs now make up nearly 98% of new car sales, and China, where used EV values are rising fast while used gas cars are becoming hard to sell, with some dealers reporting near 10% monthly price drops. The math he lays out: a typical gas car burns about $200 a month in fuel plus $100 in maintenance, versus roughly $50 a month for electricity and $50 for upkeep on an EV, if you can charge at home. He argues that gap will push used gas car values down as more affordable used EVs hit the market. He's careful to note the US isn't there yet, and may not get there on his timeline. Reasons include: the federal EV tax credit already expired, EV sales share here is still under 6%, Americans drive a lot of trucks with no cheap used electric equivalent yet, cars last nearly 13 years on average so the fleet turns over slowly, and roughly a third of households can't easily charge at home. For homeowners weighing a future car purchase, the piece is a reminder that home charging access is central to whether an EV actually saves money for your household.
Slate will offer a high roof cargo version of its compact pickup – and you can buy it!
This is auto industry news, not a home energy story, but here's what happened: Slate Auto, the company behind a stripped-down $25,000 electric pickup, is adding a high-roof cargo topper that anyone can buy, not just fleet and government customers. The kit will come in two styles: a standard square back matching Slate's existing SUV cargo option, and a new high-roof version with a spoiler cap that replaces the top of the cab for a smoother roofline. Both come in white or black, buyers can remove the rear cab glass and bulkhead, and side panels come in three choices, blank, glass, or glass with lift struts and locks. Pricing starts around $3,000. Company representatives said fleet and municipal buyers are already picturing custom builds like refrigeration units, slide-outs, and even vending machines mounted on the truck. Slate also said its next-generation truck will keep the same basic dimensions, so aftermarket parts built for today's model should still fit later versions. None of this affects home electrical, solar, or heat pump upgrades. If you're weighing an EV purchase alongside home energy work, the relevant detail here is just that Slate's cheap electric pickup is getting more customization options as the company works toward its first deliveries.
Hyundai Bets Big On Extended-Range Electric Vehicles
Hyundai plans to sell a new kind of plug-in vehicle in the US: the extended-range electric vehicle, or EREV. Unlike a typical plug-in hybrid, where a gas engine can power the wheels directly, an EREV runs entirely on electric motors, with the gas engine only spinning a generator to recharge the battery. Hyundai says its first model, a three-row Santa Fe with two motors for all-wheel drive, will offer a combined range over 600 miles and quicker acceleration than a standard hybrid. It will be built in Alabama alongside the gas and hybrid versions. Hyundai's luxury brand, Genesis, will bring the same technology to a version of its GV70, with a claimed range of 640 miles. Beyond these two models, Hyundai says it will add 10 new hybrid models in the US by 2030, when hybrids are expected to make up half its sales, and plans to expand its North American factory capacity by 500,000 vehicles a year by then. The company is also reportedly working on pickup trucks and body-on-frame SUVs, following interest in the New York Auto Show Boulder concept. Hyundai isn't alone in this move. Stellantis is developing its own EREV powertrain for the Jeep Grand Wagoneer and a Ram pickup, Ford is said to be working on an EREV truck, and Volkswagen's Scout brand is considering the technology for two upcoming models. For homeowners weighing an EV purchase alongside home charging plans, this signals more long-range plug-in options may reach dealer lots in the next few years, alongside fully electric and gas models.
Title: Sizing gutters with SMACNA/NIST formulas vs. the standard “5-inch rule”
This one's not really news for homeowners. It's a forum post on a building-advice site where someone asked about gutter sizing math, and two site moderators quickly flagged the post as spam — likely generated to promote a third-party calculator tool — rather than a genuine discussion. No building experts weighed in with real guidance. The underlying question is a reasonable one, though: most gutter installers size gutters using a simple rule of thumb (a standard 5-inch gutter for roofs up to a certain size), while engineering formulas from groups like SMACNA and NIST account for local rainfall rates and roof pitch, which can matter more than roof size alone. The post claimed that for a smaller roof in moderate rain, a much narrower gutter than the standard 5-inch size would technically handle the water, and pointed to a rule requiring downspouts of at least 7 square inches in cross-section to avoid clogging with debris. Since this exchange was flagged as spam rather than vetted advice, there's nothing solid here to act on for your own house. If you're curious whether your gutters are properly sized for your roof and your local rainfall, that's a question worth raising with someone who installs or inspects gutters in your area, since actual answers never appeared in this thread.
Op-Ed: The World Lost A Stealth Eco-Monarch with the Passing of King Harald V
Norway's King Harald V died on August 28, 2026, at 89, ending a 35-year reign. His son now rules as King Haakon VIII. Beyond his personal warmth and decades of environmental advocacy, including about 20 years as president of WWF Norway, Harald's reign coincided with the fastest shift to electric vehicles of any developed economy: EVs made up under 1% of new car sales in 2010 and 97.6% by early 2026, with Norway's electric passenger car fleet passing one million vehicles that June. Tax breaks, toll discounts, and bus-lane access helped, but so did something harder to legislate: a monarch who couldn't endorse policy but could quietly drive electric cars himself and speak yearly about climate change as a matter of shared values rather than politics. None of this affects your home directly, since Norway's incentives and grid (about 98% renewable, mostly hydropower) are specific to that country. But the piece uses Norway's steady, non-partisan approach as a contrast to recent U.S. policy swings, including the 2025 reconciliation bill that ended the $7,500 federal EV tax credit and cut home charger incentives, and accelerated phaseouts of solar and heat pump (a heating and cooling system that moves heat rather than burning fuel) credits that were meant to run for years longer. The larger question raised is whether Norway's climate consensus continues under Haakon VIII, or whether it depended more than expected on one king's long consistency.
Online Army Draws Attention To Elon Musk And The Nepal Flood Disaster
This is a story about disaster relief and government cuts, not home energy upgrades, but here's what happened. Massive flooding in Nepal, tied to a glacial event, has killed at least 752 people with 2,502 still missing; China reports additional deaths and missing people, including foreigners in Tibet. About 100 US citizens are among the missing in Nepal and Tibet. The news connects the disaster to earlier budget cuts made under the Trump administration's "DOGE" cost-cutting office, led by Elon Musk. Former USAID official Jeremy Konyndyk says DOGE canceled seven disaster risk reduction projects in Nepal and $420 million in climate-related work at NASA, including a joint USAID-NASA program that tracked flood prediction, early warning systems, and dangerous glacial lakes in Nepal. Konyndyk notes it's hard to say whether those programs could have prevented this particular flood, calling it an unusual event, but says that was their purpose. The piece also points to US flood risks, noting North Carolina's 2024 flood-disclosure law took effect shortly before Hurricane Helene struck the state, killing over 100 people. It draws a comparison to the 2004 Indian Ocean tsunami, when warning systems existed but couldn't reach people in time. The State Department says it's sending just over $3.6 million in emergency aid to Nepal, including food assistance for up to 10,000 flood-affected households. There is no news here about home energy programs, rebates, or upgrades.
West Point’s only climate scientist fired after continuing to teach human causes of climate change
West Point fired its only climate scientist, Dr. Adam Kalkstein, after he refused to stop teaching cadets about the human causes of climate change. Kalkstein, who taught at the military academy for 17 years, says he was ordered last September to cut that material from his courses. In a tense meeting the following month, he told the academy's dean the order was immoral and possibly illegal, comparing it to teaching law without mentioning the Constitution. The dean reportedly responded that President Trump, as commander in chief, sets the agenda at West Point, then left the meeting. Kalkstein was terminated after this spring's semester and has sued, claiming the academy violated his First Amendment right to free speech. This is the second lawsuit from a West Point educator over academic freedom this year. A law professor there sued after being told to "stop talking and sit down" for objecting to a policy requiring civilian faculty to get approval before publishing papers or giving speeches; the academy has since dropped its defense of that policy. Kalkstein's lawyer describes him as a conservative Republican who is not driven by politics but believes cadets need accurate information about climate change for national security reasons. West Point has acknowledged the allegations but declined to comment further. This story is about academic freedom and climate policy inside a military institution — it doesn't involve any rebates, technology, or upgrades relevant to your own home.
Poland’s Coal Problem Has Changed
Poland is moving away from coal power faster than expected. Coal made up 72.5% of the country's electricity in 2021; by 2025 that had dropped to 52.7%, with renewables at 31.4%. In June 2025, renewables generated more electricity than coal over a full month for the first time. But the coal that's disappearing is being replaced by a mix of renewables and natural gas, not clean power alone — gas generation grew significantly both years. The more complicated story is about reliability, not just how much electricity gets made. Poland still pays coal plants to stay available for its hardest hours — high demand combined with weak wind and no sun. A September 2025 auction locked in backup capacity commitments for 2026, including high-emitting coal plants, with similar auctions planned through 2028. At the same time, Poland curtailed twice as much renewable power in 2025 as the year before, because its grid can't always absorb all the solar and wind it produces. The country's first offshore wind farm started delivering power in mid-2026 and should eventually cover a few percent of national demand. Forecasts expect renewables to keep growing fast and pass coal's annual output by 2028. None of this involves direct rebates or programs for individual households — it's a look at how one country's power grid is shifting away from coal, and why closing coal plants for good depends on more than just building solar and wind farms.
E-quipment highlight: Tiger electric baggage tug hauls 30 TONS [video]
This is a story about airport equipment, not something that touches your own house, but it's a good look at where electric power is spreading. A company called Waev has an electric baggage tug, the Tiger Li-Ion, that can haul up to 60,000 pounds and runs on a 48 kWh battery pack for up to 60 miles a day. It replaces the diesel tugs that pull luggage carts (and sometimes planes) around airport tarmacs. The appeal is mostly about cost and emissions at the airport level. Waev says each electric tug saves fleet operators more than $19,000 a year in fuel and cuts more than 3.5 tons of carbon emissions annually, savings that add up when an airport runs dozens or hundreds of these machines. The tug can recharge on a standard 120-volt outlet or a 240-volt, 50-amp Level 2 charger, so it doesn't need special charging infrastructure. None of this changes anything about home energy upgrades or rebates. It's simply a sign of electric vehicles and equipment expanding into heavy-duty, commercial uses well beyond passenger cars, in this case ground support gear at airports.
Survey Sunday: will the Ford Fathom steal Slate Auto’s thunder?
This is an auto industry story with no direct home-energy angle, but worth a quick note for anyone weighing an electric truck purchase. Ford has announced an upcoming electric pickup called the Fathom, priced around $30,000 and just a few thousand dollars more than the bare-bones electric truck coming from startup Slate Auto (backed by Jeff Bezos). Electrek asked readers whether Ford's cheaper, dealer-backed truck would undercut Slate before Slate even ships its first vehicle. Nearly 2,700 people responded, and most said it's too early to tell or that a few thousand dollars still matters to buyers on a budget. Readers who did take a side were split. Some argued Ford's nationwide dealer network, often seen as an advantage, could backfire through markups and a bad sales experience, giving Slate room to compete despite being a new company. Others compared Slate's stripped-down, customizable design to Ford's own Model T and Falcon, suggesting Ford has succeeded before with simple, affordable vehicles and could do it again. One commenter raised a different concern: Slate doesn't need the Fathom to be a better truck to hurt Slate's sales — just the announcement that it's coming could make shoppers hold off on ordering a Slate while they wait to compare. Nothing here changes any current EV rebate, charging, or ownership information for homeowners. It's simply a look at how two upcoming affordable electric trucks are being compared before either has actually reached buyers.
Lucid’s ‘fire risk’ recall was for LED lights & already fixed by a July software update
This one's about cars, not home energy upgrades, but here's the gist for context: Lucid recalled 27,185 of its Air electric vehicles, from model years 2022 through 2026, after finding a fire risk tied to the exterior LED lights. The software controlling those lights, through a component called an eFuse, didn't properly limit current, which could cause the lights to overheat and, in rare cases, smoke or catch fire. Over three years, Lucid found three fire incidents and four smoke incidents linked to the issue. The good news is the fix was already released in July as a software update, since Lucid vehicles connect to the internet and can update remotely. By August 20, about 20,700 of the affected cars had already gotten the update automatically, with roughly 6,500 still needing it. Owners without the fix will get a mailed recall notice around October, but there's no need to wait for that letter to update the car's software. Lucid recommends parking outside until the update is applied, which is standard recall caution. If your vehicle already has the update, there's nothing more to do. If you're not sure, checking for the latest software version resolves the concern, since the fix simply reduces power sent to the lighting circuits and stops the system from repeatedly trying to reactivate a light that's faulted.
Top Selling Electric Vehicles in the World — 27% EV Share in July!
Global electric car sales keep climbing. In July, plug-in vehicles (all-electric and plug-in hybrid combined) made up 27% of new car sales worldwide, up from about 24% for the year so far. Fully electric models are driving that growth, up 16% year over year, while plug-in hybrids are down 11%. For comparison, the worldwide EV share was just 6% five years ago and around 1% a decade ago. The United States is an exception to the trend: sales here are still down since the federal EV tax credit ended, though the drop has eased since earlier in the year. On the sales charts, Tesla's Model Y remains the world's top-selling model, but its Model 3 sedan had a rough month, likely due to limited supply rather than falling demand. Smaller, cheaper EVs are gaining ground globally, filling out much of the top ten. That shift toward affordable compact models is a sign that electric cars are moving beyond early adopters and into the mainstream car-buying market. None of this changes any home energy program or rebate directly, but it matters if you're weighing a home EV charger or thinking about how your household's driving costs might shift over time. As more affordable EV models reach the market, and as manufacturers keep expanding their lineups, the case for installing a charger at home may get stronger, especially if you're already planning electrical upgrades tied to a heat pump or panel replacement.
XPENG Drives Physical AI To Next Level
This news is about electric vehicle maker XPENG, a Chinese company, and doesn't have a direct connection to home energy upgrades or rebates. It covers the company's self-driving car technology, a humanoid robot venture, and its latest financial results. Briefly, XPENG reported quarterly revenue of $2.91 billion, up 8% from last year, though the company posted a $200 million net loss due to heavy research spending. It also rolled out an update to its self-driving software, called VLA 2.0, which the company says improves response speed and safety, and can be controlled by voice commands. Separately, XPENG's robotics division raised $900 million to develop a humanoid robot called IRON, which is set to appear in the company's retail stores this year with sales to outside businesses starting in 2027. None of this touches home weatherization, heat pumps, or rebate programs, so there is nothing here that affects decisions about upgrading your house. It's simply a look at how one automaker is expanding beyond building cars into software services and robotics.
Bentley Launches Its Very First — No, Second — No, Third — Electric Car
Bentley will unveil its Torcal SUV on September 23, calling it the automaker's first fully electric car built entirely in-house. That's a bit of a stretch, since Bentley has sold plug-in hybrids since 2018 and backed a small electric replica car called the Blower Jnr in 2023. But the Torcal is different: it uses an electric platform shared with sister brand Porsche's Cayenne, with styling touches from Audi, and it's built without an outside partner. The Torcal is pitched as a smaller, city-friendly SUV that sits below Bentley's gas-and-hybrid Bentayga. Reviewers who rode in a prototype noted a piped-in engine sound recorded from live musicians rather than an actual V-8, along with new materials including a Merino wool fabric made with a British cloth maker and a walnut veneer built from recycled wood layers. U.S. pricing starts at $230,150, with 2028 models expected to reach buyers early next year. A waitlist is open now. None of this has much to do with affordable home or transportation upgrades — this is a six-figure luxury vehicle aimed at a narrow slice of buyers. The broader signal is that even ultra-luxury automakers now see a future in electric vehicles, even as some U.S. automakers pull back. If you're watching the EV market for signs of where affordable options are headed, this isn't it; cheaper electric trucks and cars, like Ford's upcoming Fathom pickup, remain the ones more likely to matter for a typical household's driveway.
Amazon’s massive 2026 Labor Day sale now live! Thousands of deals: Apple, Android, TVs, tech under $100, more from under $5
This is a general retail deals roundup, not energy-efficiency or home-upgrade news, so there is nothing here that relates to planning insulation, heat pumps, air sealing, rebates, or other efficiency improvements for a house. The article covers Amazon's 2026 Labor Day sale, a 10-day discount event running through September 7 on electronics, Apple products, smart home devices, and general merchandise. Highlighted items include AirPods, iPhones, Mac minis, TVs, Ring cameras and doorbells, Amazon Echo devices, gaming monitors, coolers, and kitchen and outdoor party supplies, with prices ranging from a few dollars up to over a thousand for phones and computers. None of this touches on home energy upgrades, weatherization, rebate programs, or equipment like heat pumps or insulation, so it does not affect any decisions a homeowner would be making about improving their house's energy efficiency.
Amazon’s massive 2026 Labor Day sale now live! Thousands of deals: Apple, Android, TVs, tech under $100, more from under $5
This article is about a general Amazon retail sale, not home energy upgrades, so it doesn't have direct relevance to planning energy-efficiency projects or finding rebates for your house. The piece covers Amazon's 2026 Labor Day sale, a 10-day event running through September 7 with discounts across electronics, Apple products, smart home cameras, TVs, and general merchandise. Deals mentioned include AirPods Pro 3, iPhone 17 Pro models, Ring security cameras and doorbells, Fire TV streaming devices, Bose headphones, gaming monitors, and various kitchen and outdoor gear. None of this touches on insulation, heat pumps, weatherization, or utility and government rebate programs that would affect a home's energy use or costs. If you're researching ways to lower your heating and cooling bills or qualify for rebate programs, this sale isn't the place to look. It's worth checking dedicated energy-efficiency resources or your state or utility's rebate programs instead, since those often have separate deadlines and dollar amounts that matter more to a home upgrade budget than a retail electronics sale.
Common HVAC Shortcuts That Lead to Bigger Problems
A trade publication piece aimed at HVAC technicians lays out several shortcuts during routine service calls that can quietly wear down a system over months, even though nothing looks wrong on the day of the visit. The issues include using the wrong cleaning chemical on an air conditioner's coil (which can corrode it over time), skipping a protective coating after cleaning in salty or humid areas, and relying only on an electronic leak detector rather than pairing it with a bubble-solution check to pinpoint the exact leak spot. Other shortcuts involve using the wrong sealant on refrigerant line fittings, and dropping a single tablet into the condensate drain pan (the tray that collects water dripping off the cooling coil) without actually breaking down the slimy microbial buildup, called biofilm, that clogs drains and pipes over time. None of this points to a scam or dangerous practice; it's a technician-focused reminder that small product and technique choices during a service visit can shorten a system's life or lead to a repeat service call weeks or months later. For a homeowner, the takeaway is mainly background: if your system needs a repeat repair not long after a maintenance visit — a coil that corrodes faster than expected, a leak that keeps recurring at the same joint, or a drain that clogs again soon after cleaning — these are the kinds of underlying causes that can be at play, rather than necessarily a sign of a bigger equipment problem.
The Real Electric Aviation Revolution Is Being Strangled To Enrich Don Jr. & Other Trump Associates
This isn't directly about home energy upgrades, but it touches a tool some homeowners use to check their houses: small camera-equipped drones, including ones with thermal cameras that spot heat leaks in roofs and walls. The FCC has proposed a rule (Public Notice DA 26-758) that would revoke approvals for many foreign-made commercial drones and ban importing them, along with replacement parts like batteries and motors, by labeling them "military-grade." The definition is broad enough to cover drones with basic thermal cameras, distance sensors, or automated charging docks, the kind of consumer and small-business drones used for roof inspections, search and rescue, and hobbyist photography. If the rule goes through, affordable drones in the $1,500 to $3,000 range could disappear from the market, since domestic alternatives with similar sensors reportedly cost $15,000 to $25,000. Because drone batteries wear out after 150 to 250 charging cycles, banning imported replacement parts would also ground drones people already own within a year or two. Critics point out that Donald Trump Jr. was appointed to the advisory board of a small domestic drone-parts company, Unusual Machines, and received stock that jumped in value after the announcement. For homeowners, the practical upshot is that a common, low-cost way to find heat loss on a roof or attic, thermal drone imaging, could become far more expensive or harder to access if this rule is finalized. No final decision has been made yet.
Can Rockwool batts be pushed up against screws and nails?
A homeowner planning some retrofit work asked a building forum whether mineral wool insulation (sold under the brand Rockwool) can be installed in wall or ceiling cavities where nails or screws are sticking out into the space — a common situation in older garages or basements where fasteners protrude from framing. The concern was whether the insulation, which is stiffer than fiberglass batts, would still fit snugly around those obstructions or get damaged or pushed out of shape. Two experienced builders answered that mineral wool handles this fine. Fasteners simply poke into the batt the same way they would with fiberglass, and installers likely won't notice much difference. For bigger obstructions, like odd chunks of wood framing, mineral wool needs to be notched and cut to fit around them rather than just squeezed into place, since it's less flexible than fiberglass. One builder recommends using a serrated "bread knife" style tool to cut it cleanly, including splitting batts to route around wiring. Both builders actually prefer mineral wool over fiberglass for this kind of work. Because it holds its shape, it tends to fill a cavity evenly without much fussing, while fiberglass batts are more prone to compressing unevenly or leaving gaps if not installed carefully. For a homeowner considering mineral wool batts for a retrofit project with protruding nails or screws in the wall or joist cavities, this suggests the material can be worked into place without special preparation, as long as any larger obstructions get cut around rather than forced past.
Most “Park Outside” Warnings Involve Vehicles With Internal Combustion Engines
There are currently 3.2 million vehicles in the US carrying a "park outside" recall warning, which tells owners to keep the car away from homes and other buildings because of fire risk. Most people assume this is an electric vehicle problem, but the opposite is true. Federal recall data reviewed by the Washington Post shows gas and diesel vehicles account for the vast majority of these warnings. Since 2021, gas-only recalls have covered 4.6 million vehicles, compared to about 662,000 for EVs and hybrids combined. The cause usually isn't a battery. It's "always on" electronics — things like seat-heater switches, power steering wiring, starter relays, and control modules — that stay powered even after the engine is off and the car is parked. Recent examples include Kia Tellurides with a front seat switch that could overheat, and Ford Expeditions and Lincoln Navigators with battery junction box circuit boards that could short out. In 2023, Hyundai and Kia recalled a combined 3.4 million vehicles, mostly gas models, after finding their anti-lock brake systems could leak fluid and spark an electrical fire even while parked. For context, gas-powered cars catch fire at a far higher rate than EVs — roughly 1,500 fires per 100,000 vehicles sold, versus about 25 per 100,000 for EVs. If you own a car with a "park outside" recall, the notice would have come from the manufacturer or NHTSA directly, regardless of whether your vehicle runs on gas or electricity.
Beyond the Wrench: Building a Home Services Business Around Solutions
This is a business-industry story about a home services company, not news that changes what a homeowner should do about their own house. It's worth knowing about mainly as background on how the companies you might call for repairs are evolving. Fast Home Services, a company that has worked on water heaters for more than 40 years across Washington, Oregon, and California, is expanding into heating and cooling, plumbing, and electrical work. Its CEO, Tim O'Brien, says the growth means changing how the company finds and serves customers. Instead of relying on one way to bring in business, it now uses online quoting tools, AI-assisted search, retail partnerships, and other methods depending on the customer. O'Brien also talks about running the company with a "technician-first" approach — things like scheduling that works around workers' families and giving field staff more say in how they do their jobs, on the idea that well-supported technicians serve customers better. He's also planning a training center meant to bring more people into the trades. For a homeowner, none of this changes any rebate, deadline, or specific technology decision. It's simply a sign that more regional contractors are broadening beyond a single specialty — like water heaters — into full home service providers covering heating, cooling, plumbing, and electrical, which may show up as more of these multi-service offers if you get quotes for work in those states.
SupplyHouse, Tim McGraw Team Up to Honor Tradespeople
This one's not about upgrades or rebates, but it's a nice story about the people who do the work. SupplyHouse, a plumbing, HVAC, and electrical supplier, has launched a contest called The Day Savers to recognize tradespeople — the plumbers, electricians, and HVAC techs who show up when a pipe bursts or the air conditioner dies. Country singer Tim McGraw is helping spread the word; his nephew works in the trades and runs his own company. The idea: people post a short video on social media telling the story of a tradesperson who helped them out, tagging SupplyHouse's account and using the hashtag #TheDaySaversContest. Nominations are open through Wednesday, Sept. 9. Public likes, comments, and shares will narrow the field to 25 finalists, and a SupplyHouse panel will judge them on impact, dedication, and how strong the story is. Ten winners will each receive $10,000, announced on National Tradesmen Day, Friday, Sept. 18. If a plumber, electrician, or HVAC tech has ever bailed you out of a bad situation — a flooded basement, a dead furnace in winter — this is a chance to give them public recognition, and possibly a cash prize. It doesn't affect any rebate programs or energy upgrades, but it's worth knowing about if you want to say thanks to someone who's helped keep your house running.
California Sues Trump Over Ridiculous Wind Power Cancellations
California is suing the Trump administration over a deal that killed a major offshore wind project. In April, the U.S. Department of the Interior agreed to pay Golden State Wind $120 million in taxpayer money to give up a lease it had bought in 2022 to build a floating wind farm off California's Central Coast. The company also agreed to put money into fossil fuel projects instead. State Attorney General Rob Bonta filed suit in federal court in Northern California, arguing the deal broke federal law and should be thrown out. The canceled project was a two-gigawatt floating wind farm, large enough that Golden State Wind had also planned to spend $30 million on job training, supply-chain work, and other community benefits in the state. California argues the cancellation costs the state jobs and investment, on top of the taxpayer money spent, and raises broader concerns about air quality and climate impact. This doesn't change anything about home energy rebates or upgrade programs directly. It's a dispute over a large offshore power project, not a residential incentive. But it's a sign of the ongoing pullback in federal support for wind energy, which is part of the broader mix of clean electricity that can affect power prices and grid supply over time. Homeowners weighing upgrades like heat pumps or solar don't need to act on this news, but it's worth watching if you're tracking how federal energy policy shifts might ripple into utility rates or state-level programs down the road.
US Army Aims To Capture Energy From “The Environment”
This one is about the battlefield, not your basement, but it shows where battery and solar technology is headed. A defense startup called Chariot Defense just won a $7.6 million contract from the Pentagon's Defense Innovation Unit to supply the Army with a portable microgrid system called Amphora. The pitch: replace loud, hot diesel generators with a battery-backed system that can pull power from tactical generators, idling vehicles, wall outlets, or, as the company puts it, "the environment" — a phrase that avoids saying "solar" or "renewable" directly given the current administration's politics around clean energy. The bigger story is that even under a fossil-fuel-friendly federal posture, the military keeps investing in batteries, storage, and local power generation because it solves real problems: diesel convoys are dangerous and expensive, and generators give off heat and noise that expose troop positions. The Army has also been testing solar-linked hydrogen fuel cells, and a separate Pentagon office is backing a space-based solar power startup. None of this changes any rebate or program available to homeowners right now. But it is a reminder that the battery and microgrid technology improving for military use — compact, efficient, storage-paired power systems — is part of the same wave of innovation that eventually filters down into home batteries and backup power systems you might consider pairing with rooftop solar.
Vycarb Successfully Stores Low-Purity CO2 In Seawater
A Brooklyn startup called Vycarb has hit a milestone in a different kind of climate technology: capturing carbon dioxide from industrial exhaust and storing it in seawater rather than underground. This is carbon capture and storage (CCS), a process usually associated with power plants or factories, not homes. Vycarb's system dissolves CO2 in water using common limestone, turning it into a stable, harmless compound called bicarbonate. The company just showed it can do this even with "dirty," low-purity CO2, which normally makes capture expensive, since gas has to be cleaned before it can be stored underground. Vycarb's method skips that cleanup step entirely. None of this involves anything homeowners install or pay for directly. The technology is aimed at industrial emitters like cement plants, wastewater treatment facilities, and fuel producers, who can earn money through tax credits and carbon markets by using it. There's no rebate, product, or home upgrade tied to this news. The broader relevance is about the fight against climate change generally: cheaper, easier carbon capture could help slow emissions from industries that are hard to fully decarbonize, like cement making and sewage treatment. That's a background factor in the push toward cleaner energy overall, but it doesn't change what's available for insulation, heat pumps, or other home efficiency upgrades. If you're weighing upgrades to your own house, programs like weatherization assistance or heat pump rebates are unaffected by this development.
Vycarb Successfully Stores Low-Purity CO2 In Seawater
A Brooklyn startup called Vycarb has made progress on a way to capture carbon dioxide from industrial exhaust and store it permanently in seawater, without the usual step of purifying the gas first. That purification step is normally the most expensive part of carbon capture. In tests at the company's Brooklyn Navy Yard pilot site, Vycarb converted 99% of CO2 gas into water even when the gas was only 50% pure, and turned 85% of that into stable bicarbonate, a dissolved form of carbon that stays put rather than escaping back into the air. The process uses cheap, common alkaline minerals like agricultural limestone, and the company says it has tested purities as low as 1.5% in the lab, close to the concentration found in raw exhaust from burning fossil fuels. This is industry and policy news rather than something that touches your house directly. It matters mainly because it could make carbon capture cheaper and easier to use at cement plants, wastewater treatment facilities, and other coastal industrial sites, backed in part by federal tax credits and corporate investors including Shell and Rio Tinto. There's no home upgrade or rebate tied to this story. It's a technology and business development in the broader effort to cut greenhouse gas emissions, not a program homeowners can sign up for or a product that will show up on a house anytime soon.
Methane Thermolysis Has A Carbon Market Problem
A new process called methane thermolysis is getting attention as a cleaner way to make hydrogen. Instead of burning methane and releasing CO2, it uses heat to split methane into hydrogen gas and solid carbon, avoiding the need to capture and store carbon dioxide. A company called Hazer Group has moved this technology from the lab to a demonstration plant and is working on larger commercial designs. The catch is math, not chemistry. For every tonne of hydrogen this process makes, it also produces roughly three tonnes of solid carbon. A plant making 300,000 tonnes of hydrogen a year would also produce about 900,000 tonnes of carbon, or 2,500 tonnes a day. That carbon has to go somewhere. Even in the best-case scenario analyzed, pairing the hydrogen with a large steel plant that uses both the hydrogen and some of the leftover carbon, roughly 80 to 90 percent of the carbon still has no buyer lined up. It would need to compete with existing carbon products already used in batteries, asphalt, and concrete, markets that are limited in size or require very specific material qualities. None of this makes the technology bad, and it could work well in specific spots with the right mix of gas supply, hydrogen demand, and nearby buyers for the carbon. This is industry-level news about how hydrogen production technology is developing. It does not point to any near-term rebate, product, or decision for homeowners, but it is part of the broader landscape of hydrogen and clean-energy technology still working out its economics.
How rising temperatures likely contributed to Nepal’s deadly flood
A flash flood on the Nepal-Tibet border this week killed roughly 160 people, with hundreds more, including international tourists, still missing. Scientists believe the disaster began when a chunk of glacier, about 2,000 feet wide, broke off and fell nearly 4,000 feet into a valley, crushing itself into water with the force of the fall. The impact was strong enough to register as a magnitude 5.2 seismic event. Researchers point to warming temperatures as a likely factor. Glaciers in the region have been thinning and retreating for decades. Nepal's glaciers lost nearly a quarter of their area between 1970 and 2010, and more than 160 smaller glaciers have disappeared entirely. Worldwide, glaciers have lost 5 percent of their ice since 2000, and one study warns that 40 percent of the planet's glacial ice could vanish if warming isn't kept under 1.5 degrees Celsius. As glaciers shrink, they lose their grip on surrounding rock and sediment, which can trigger landslides, and thawing permafrost (ground that used to stay frozen year-round) can loosen ice and debris that used to stay put. Melting also often leaves behind dammed lakes at high elevation that can burst catastrophically if a landslide hits them, something Nepal saw twice last year. This event happened far from most readers' homes and doesn't call for any action on your part. But it's part of a broader pattern: as the world warms, ice in mountain regions is becoming less stable, and similar glacier collapses have caused deadly incidents in Switzerland and Italy in recent years.
MediaEd Insights: Food as Ecomedia Literacy
This piece is a personal essay, not home-upgrade news, so there's nothing here that changes what you'd do with your own house. The author, a media literacy researcher, writes about growing up eating processed, meat-heavy meals and later becoming a vegetarian as she learned more about food's environmental toll. She points out that agriculture accounts for roughly a quarter of human-caused greenhouse gas emissions, coming from farm equipment, fertilizer production, and methane from livestock, but says most media coverage skips over meat and livestock as climate factors. The essay's main point is about "food media literacy," a way of critically examining how news, ads, and social media influencers shape what people think and believe about food, nutrition, and its ties to climate and social issues. It's the first of five essays in a series exploring food systems through this lens. There's no program, rebate, deadline, or technology mentioned here that applies to weatherizing a home, installing a heat pump, or cutting energy bills. If you're tracking energy-efficiency upgrades for your house, this article doesn't affect those plans directly. It's worth knowing about mainly if you're curious about how food and climate messaging intersect in the media you consume, rather than about your home's energy use itself.
Illinois just made 40 mph e-bikes street legal – but there’s a huge catch
This is a transportation story, not an energy-efficiency one, but here's what happened for anyone with a fast e-bike or e-moto: Illinois signed a new law (taking effect January 1, 2027) that finally addresses the powerful electric bikes capable of 35 to 40 mph that don't fit the standard e-bike categories. These "e-motos" have mostly been operating in a legal gray area, since normal e-bikes are limited to lower speeds. Under the new rules, bikes with motors rated between 750 and 8,000 watts get reclassified as "electric motor-driven cycles" — essentially treated like motorcycles. To ride one legally on the road, you'd need a driver's license, title, registration, and insurance, and you couldn't use sidewalks or bike lanes. The catch: most of these bikes already on the market, and likely sitting in garages, were never built or certified as motor vehicles. They lack a real vehicle identification number tied to federal safety certification, and the law requires that documentation before a bike can be titled or registered. Adding mirrors or turn signals yourself won't satisfy this. So while the law technically opens a path to legal road use, most existing fast e-bikes can't actually qualify. The bigger effect may be on future models, if manufacturers start building these bikes to meet federal motor-vehicle standards so they can eventually be registered.
MacGregor says demand for its electric cranes is BOOMING in 2026
This is industry news about maritime shipping, not something that affects home energy upgrades directly. MacGregor, a Swedish company that makes cranes for cargo ships, says demand for its electric cranes is way up in 2026, now making up more than 80% of its new crane orders. Over the past fifteen years, more than 600 container ships have been fitted with the company's electric cranes. The appeal of electric cranes over traditional hydraulic ones includes lower energy use (up to 60% less), more precise load placement, better performance in cold weather, and no risk of hydraulic oil leaking into water or onto land. Ports investing in cleaning up their operations, including the Port of Los Angeles and the Port of New York and New Jersey, are favoring this equipment as part of that push. The company is also working on autonomous crane technology, recently showing a concept crane developed with a Norwegian university as part of an EU-funded research project. Its CEO said the next step involves working out international rules and safety standards for autonomous systems. None of this involves rebates, incentives, or equipment relevant to home energy upgrades. It reflects a broader shift in shipping toward electrified, lower-emission machinery, similar to trends showing up in other heavy industries.
Robot delivery dog dumps hot steaming packages on your doorstep [video]
This story is about a delivery robot, not a home energy upgrade, so it has no real bearing on your house or any rebate program. A company called Robot.com has unveiled a concept delivery robot shaped like a dog, called R-dog, meant to drop packages at doorsteps. It's built to look approachable, with expressive eyes and a furry tail, and it can supposedly climb stairs and get around obstacles better than the boxier delivery robots already on some city streets. The bigger twist is that R-dog doubles as a moving billboard. It carries screens that play ads while it delivers packages, and its cameras and sensors are also used to track who looks at those ads, measuring engagement for advertisers. The company says it limits how long it keeps this data and lets people request access, correction, or deletion of their own information by email, though how a passerby would even know to do that isn't clear. None of this involves weatherization, heat pumps, insulation, or any rebate program that would affect your home's energy costs. It is simply a look at where delivery-robot and advertising technology is headed, tested so far on streets in Miami Beach. If you're weighing actual home upgrades, this one is worth skipping.
666 – il marchio della Spiaggia Lucciola Elettrica con un ricarico del 13 percento
This is car news, not a home energy story, so there's nothing here about upgrading your house or finding rebates. The article covers Nio, a Chinese automaker, launching a limited special edition of its Firefly hatchback called "Club Spiaggia." Only 666 units are being made, priced 13 percent above the standard Firefly. The special edition costs 135,800 RMB (about $20,200), or 95,800 RMB (about $14,250) if the buyer uses Nio's Battery as a Service program, which lets drivers subscribe to a battery rather than buy it outright. The car comes in a new "breeze blue" color meant to evoke Italy's coastline, with striped graphics, orange accents, and beige "sunny siesta" interior upholstery. Deliveries to Chinese retailers began this week. None of this involves home heating, cooling, insulation, or any equipment that affects a house. There's no rebate program, no efficiency standard, and no policy change relevant to homeowners. If you're tracking energy-efficient upgrades for your own home, this piece has no bearing on that — it's simply a look at a niche vehicle trim aimed at the Chinese market.
Europe EV Sales Report: BEVs Reach 26% Market Share!
Fully electric cars are selling fast in Europe. In July, about 288,000 battery-electric vehicles (BEVs) were registered, up 51% from a year earlier, giving them 26% of the market that month. Add in plug-in hybrids and the total plugin share was 38%. For the year so far, electric cars hold 23% of the market, already ahead of last year's full-year result. Tesla had a weak month, down 36%, showing that other automakers are now driving the growth instead of relying on one brand. How fast electric cars are catching on still varies widely by country. In Norway, 98% of new cars sold are electric; Denmark is at 80%, and several other northern European countries are well above 40%. Italy and Czechia, by contrast, sit at just 6% and 8%. This matters if you're watching prices and choices in your own market: places with more electric cars on the road tend to have more competition, more model choices, and often lower prices, while regions with fewer EVs may see slower price drops and fewer options for now. On the model side, smaller and midsize electric cars from Skoda, BMW, Renault, and others took top sales spots this month, and several new budget-friendly city cars and compact SUVs are due out over the next year or two from brands including Dacia, Renault, Volkswagen, and Fiat. For anyone shopping in Europe, that points toward more affordable electric options arriving soon, though timing and pricing details weren't specified.
California Legislature Passes Heat Pump Permitting Bill
California lawmakers have passed a bill meant to make it faster and cheaper to install heat pumps in existing homes. Senate Bill 222, the Heat Pump Access Act, would set a standard permitting process across the state's roughly 600 local jurisdictions, replacing the current patchwork of rules, fees, and inspection requirements that can slow down installations and add to their cost. The bill passed both chambers of the legislature and now goes to Governor Gavin Newsom, who has until September 30 to sign or veto it. If signed, the law would require local governments to offer automated permitting for standard heat pump jobs, issue a single permit instead of multiple approvals, cap and clarify permit fees, and post permitting rules online. Starting July 2027, jurisdictions would have to allow inspections that don't require the contractor and inspector on site at the same time. By July 2028, they'd need a fully automated online system that issues permits in real time when requirements are met. The bill also limits how much homeowners associations can restrict heat pump HVAC systems and heat pump water heaters. It does not apply to new construction, only upgrades to existing homes. Supporters point to data suggesting homeowners save an average of $304 a year by switching to a heat pump for heating and cooling, and $97 a year with a heat pump water heater. They also cite a survey finding over 90% of heat pump owners are satisfied with their systems. If you're considering a heat pump for your own house, this bill could eventually mean less paperwork and a quicker permitting process, though the timeline depends on how fast your local government adopts the new rules.
So, where exactly does the US energy transition stand?
Analysts are debating how much damage federal policy changes have done to the country's shift toward clean energy, and the honest answer is nobody knows for sure. One MIT researcher argues power-sector emissions are still on track to drop substantially by 2035, since many wind and solar projects locked in tax credits before they were eliminated, as long as they finish construction within four years. Other researchers, including at the Natural Resources Defense Council, say the country will still fall well short of the emissions cuts it would have seen under prior policy. Most agree clean energy building should stay fairly strong through 2030, but what happens after that is anyone's guess, depending on energy prices, permitting fights, and the 2028 election. None of this changes what's available to homeowners right now, but it's worth knowing the backdrop: incentives tied to specific project types can still work through their grandfathered timelines even as broader federal support shifts. Elsewhere, Tesla is discontinuing its solar roof shingles after years of underwhelming sales, and will focus instead on standard solar panels, including a new Texas factory. Globally, renewable energy investment remains strong, with residential solar investment rising sharply and solar power expected to produce more electricity than coal worldwide for the first time this year. In Europe, solar helped keep air conditioners running through record heat and drought this summer, even as other power sources struggled.
California passes bill allowing customer-owned clean energy to compete with traditional power sources for grid reliability
California has passed a new law, Senate Bill 913, that could let homeowners get paid more easily for the clean energy equipment they already have installed. The bill orders the state's utility regulator to rework how it plans for grid reliability, so home batteries, solar-plus-storage systems, electric vehicles with two-way charging, smart thermostats, and heat pumps connected to the grid can compete alongside traditional power plants to keep the lights on during peak demand. For homeowners, this matters because utilities like PG&E, Southern California Edison, and San Diego Gas and Electric will now have to count these home devices as real sources of grid capacity, not just extras. The law also makes it easier to register a home system with a "virtual power plant" program, which bundles many households' devices together so the grid can draw on them during heat waves or high-demand evenings. It allows one property to combine several technologies, such as an EV charger, thermostat, and solar battery, into one account, and it requires payment for the power exported to be measured at the device level. The change is meant to reduce the need for utilities to build costly new power plants and transmission lines, expenses that normally show up on customer bills. Supporters argue that better use of existing home equipment can ease strain on the grid and put downward pressure on electricity rates. The law itself does not set exact payment rates yet. The California Public Utilities Commission will now begin a rulemaking process to work out the specific compensation and enrollment rules that utilities and technology providers will follow.
1 in 7 US students now goes to a solar-powered school
More than 10,800 K-12 schools across the country now run on solar power, according to a new report from Generation180. That's about 1 in 7 US students, or over 7 million kids, attending a solar-powered school. The number of schools with solar has nearly doubled since 2016, and their combined solar capacity has more than tripled to over 2.4 gigawatts. Some districts are seeing big savings: Roanoke City Public Schools in Virginia expects its solar installations to save $46.5 million in energy costs over 35 years. California has the most solar schools, followed by New Jersey, New York, Illinois, and Arizona, while Virginia, Connecticut, Pennsylvania, New Jersey, and New York added the most new solar capacity recently. Battery storage at schools is a different story. Only 155 schools nationwide have added battery systems since 2016 — less than 0.1% of all K-12 schools — though that's seven times more than a decade ago. California accounts for about 70% of these systems. Batteries let a school store extra solar power for later, reduce costly demand spikes, and keep essential equipment running during power outages. Since about a third of public schools serve as official emergency shelters, backup batteries could help the surrounding community too. This isn't something that directly changes what you can do at your own house, but it points to a broader trend: solar is spreading into more community buildings, and battery storage is starting to follow. A federal tax credit for storage remains available to schools and other tax-exempt groups even as incentives for new solar and wind projects are being phased out on a faster timeline.
For some storage developers, the ITC might not be worth it after all
Large battery storage developers are rethinking whether a federal tax credit is still worth chasing, and the answer says something about where battery prices are headed. Companies building big energy storage projects can buy battery units from China for as little as $70 to $80 per kilowatt-hour (roughly $120 after tariffs and shipping), from other countries for $130 to $140, or from U.S. manufacturers for $160 to $180. The pricier American units can qualify for a 30% investment tax credit, a federal incentive for storage projects that meet certain rules, including paying workers prevailing local wages. New restrictions tied to a 2025 law now disqualify projects if too much of their equipment is linked to China, adding cost and paperwork for developers trying to prove compliance. Combined with falling Chinese battery prices, some developers say the math no longer favors paying extra for U.S.-made batteries just to claim the credit. One industry source estimates roughly one in five storage projects now plans to skip the credit entirely. U.S. battery factories from companies like Samsung SDI and LG Energy also won't be running at full capacity until late 2026 or 2027, so developers needing batteries sooner may buy from China regardless. None of this changes what's available to homeowners today, but it points to battery and storage costs that may keep shifting as trade rules and domestic manufacturing evolve. Federal guidance on the new restrictions is still incomplete, so more changes are likely as regulators clarify the rules.
