"We were considering multiple forms of capital when we started. It just felt like the opportunity is so large that venture capital gives us the opportunity to take those risks upfront and have the possibility to generate an outsized return."

Noor, meaning light in Arabic, is a solar facility that produces enough energy to power more than a million homes, utilizing concentrated solar power instead of traditional PV panels.

Lithium-ion batteries generally degrade fastest when held at a high state of charge, which means keeping your iPhone or your Mac's battery at 100 percent accelerates the chemical wear that permanently reduces its actual capacity over time.

"We have seen a significant change in the dynamic. So definitely, when the American consumer sees an increase in fuel prices they try to move to solutions which are more friendly in terms of cost, especially in states like California."

The design of the Juke EV is quite something. It's a toned-down version of the dramatic Hyper Punk concept unveiled in 2024, but it's still going to be an unusual visual presence out on the road.

Battery degradation on high-mileage EVs is not as big a deal as some might make you believe. Real-world data shows that EVs with over 150,000 miles are still going strong, with minimal degradation. Older EVs are more affected by high mileage, but technology has made newer models more resilient. Battery degradation is inevitable, but new research shows that EV owners should just keep driving their cars without worrying about what happens with the thousands of cells that live in their cars' floors.

Last year, the company's profit fell 45% compared with 2024, driven in large part by falling sales of its electric vehicles. Investors anticipated the decline in sales, but Tesla still beat Wall Street earnings and revenue estimates thanks to its energy storage business. Tesla deployed a record 46.7 gigawatt-hours of energy storage products in 2025, a 48% increase from last year, according to the company's official filings.

The team, from the Chinese Academy of Sciences and Beijing Institute of Technology, recently published their findings in Nature Communications. According to their research, the process not only avoids conventional leaching chemicals and extreme heat to extract lithium from old batteries, but it also uses carbon dioxide in what the authors call a sequestration step, and turns other battery transition metals into new catalysts - with CO₂-rich water doing most of the chemical work.

For the most part, rechargeable battery-powered devices are incredibly well-behaved. It's a good thing, really, because most of us are happy to go to sleep with a charging smartphone not far from our head each night, and cram ourselves onto an aircraft and spend many hours at 40,000 feet surrounded by hundreds of different devices -- all of varying quality and state of repair -- containing a rechargeable battery.
