Instead of defacing clay tile roofs with standard blue or black solar panels, these 400W double-glass panels from Austria-based Sonnenkraft are available in terracota red, yet still claim a 20.02 percent conversion efficiency.
I guess Tesla is still working out the kinks with its red roof solution promised back in 2016.
The Environmental Protection Agency (EPA) just launched its Energy Star NextGen Certified Homes and Apartments program. For decades, Energy Star has certified efficient products from kitchen appliances to washers, dryers, air conditioners, and heat pumps. Now, it’s also starting to certify homes and apartments that are at least 20 percent more efficient than typical builds.
Shell sold millions of carbon credits that were supposed to represent CO2 emissions captured in Canada. But only half of those credits were linked to real eductions in pollution, according to documents obtained by Greenpeace and shared with the Financial Times. It’s an explosive investigation into carbon capture tech fossil fuel companies are using to make sustainability claims that might not pass the smell test.

The move is supposed to save the average household at least $100 a year in lower utility bills. As new water heaters are shipped out over 30 years, energy savings from the tougher standards are also expected to reduce carbon dioxide emissions by 332 million metric tons. That’s like erasing the annual planet-heating pollution of nearly 43 million homes, the Department of Energy says.

By simplifying the permitting process, the Biden administration hopes to speed the deployment of solar and wind farms and other energy projects crucial to meeting US climate goals. At the same time, the new rules are designed to make potential impacts on local communities (environmental justice) a bigger consideration when permitting new projects.
Earth Month is coming to a close, but there’s still time to catch up on The Verge’s package of stories from Costa Rica on turning cattle ranches into forests, Indigenous leaders fighting for their land back, and how the country runs on nearly 100 percent renewable electricity. On the ground in Costa Rica, we found reasons to be hopeful about solutions to climate change.
The Verge spoke to EPA administrator Michael Regan about the agency’s new rules for power plant pollution.
One of the biggest residential solar companies announced today that it’ll lay off 1,000 people. It’s also shutting down its direct sales business and residential installation locations.
“We need to achieve financial viability, which includes simplifying our business structure, transitioning away from areas where we have been unable to sustain profitable operations, and improving financial controls,” SunPower Executive Chairman Tom Werner told employees.

Costa Rica gets more than 99 percent of its electricity from renewables — it’s still not enough.
The European Space Agency plans to find out with a project called Solaris. Scientists and engineers have been trying to figure out how to make space-based solar power work since the 1960s. And the rise of the commercial space industry is finally bringing launch costs down enough to really put the technology to the test.
Newsweek notes that renewable energy hit a milestone in California, meeting 100 percent of the state’s electricity demand for up to 6 hours nearly every day of the past month.
There’s obviously still a lot of progress needed to hit the state’s goal of running entirely on carbon-free electricity by 2045, but Stanford engineering professor Mark Jacobson says this is a sign that California is well on its way there.
If you own a solar generator then chances are you’ve been caught out when the sun unexpectedly yields to rain. Bluetti’s new scalable AC240 features an IP65 rating, making it highly resistant to dust and water jets. It also supports up to 1200W of solar input to charge its 1536Wh LFP battery (expandable to 20,272Wh), and delivers 2400W of AC output with an option to double up units for 4800W.
There will be less solar energy available of course, but grid operators say they’re prepared to fill in the gaps with other sources of energy. A rare total solar eclipse will pass over 31.6 million Americans’ homes on April 8th, darkening skies for around 4 minutes in each location along its path.
“For Americans with solar on their home, it won’t be any different than a passing thunderstorm,” Abigail Ross Hopper, president and CEO of the Solar Energy Industries Association tells The New York Times.
Soundside, a daily broadcast program from Seattle’s NPR news station KUOW, breaks it down in this episode. Catch my interview about the energy and environmental costs of Bitcoin mining in the US, and the legal battle that killed the Department of Energy’s survey of miners’ electricity consumption.

This is BIG in more ways than one. With blades longer than the Statue of Liberty is tall, these are 12 massive next-generation turbines towering over the Atlantic. Together they should be able to generate 130 megawatts of clean energy for some 70,000 homes. For comparison, the US only had the capacity to generate 42 megawatts from offshore wind until now. More big offshore projects are on the way (and just a reminder, there’s no evidence to show they’re harming whales).
We are talking about the the same industry profiting by creating the climate crisis. Shell previously promised to reach net-zero greenhouse gas emissions by 2050, which is impossible unless the company pivots away from dirty energy. Shell’s blaming consumers for its own lack of follow through, saying “investment in oil and gas will be needed” to meet demand.
They’ve used AI for years to find new oil and gas reserves. Now, more advanced AI is helping them drill oil wells more efficiently. Within a few years, a significant chunk of wells could be drilled autonomously, Bloomberg reports. That brings costs down and helps dirty energy compete with renewables like solar and wind, which have become cheaper alternatives to fossil fuel power plants that wreck air quality and cause climate change.
Electricity shortages could become a big problem over the next several years unless the US races to get more sources of clean energy online, The Washington Post reports. Data centers for AI and crypto mining are huge energy vampires. And the resurgence of domestic manufacturing for everything from semiconductors to EV batteries and solar panels are also expected to put extra strain on aging power grids.

Because of all the energy it consumes, AI might actually make things worse by driving up greenhouse gas emissions. There’s also the risk of AI being weaponized to spread climate disinformation. You don’t have to take my word for it; this report from the Climate Action Against Disinformation coalition brings together current research on the issue.
But it’s not on one of his rockets. SpaceX’s Falcon 9 is carrying MethaneSat, a satellite made to measure the potent greenhouse gas methane. The Bezos Earth Fund gave the nonprofit Environmental Defense Fund (EDF) $100 million to build and launch the satellite. Google is also partnering with EDF to create a global map of methane pollution coming from oil and gas infrastructure.
The devastating Smokehouse Creek fire has already burned more than a million acres, killing at least two people, and destroying hundreds of structures. Officials are still investigating the cause of blaze. But at least one homeowner and one rancher have filed suits against utility Xcel Energy. A pole owned by Excel subsidiary Southwestern Public Service Company reportedly fell within the area where the blaze might have started.
