Extra-light, flexible solar cell could keep your smartwatch powered
Researchers have built a very light and stretchy solar cell that could keep wearable devices running without batteries.
Tesla moves the Model Y release date up to 'spring 2020'
Tesla was on quite the roll in Q4 last year. The company unveiled its controversially popular electric Cybertruck at the Los Angeles Auto Show, Elon Musk won his "pedo guy" defamation suit, and the first Model 3s produced at Tesla's new Shanghai Gigafactory rolled off the assembly line. The company also delivered 112,000 vehicles in that quarter, and 367,500 vehicles over the full year -- that's a 50 percent increase over 2018.
JBL says its solar-powered headphones deliver 'unlimited' listening
Wireless headphones are perpetually hamstrung by their batteries. They only last a few hours on a charge, and you're sapping energy from the electrical grid every time you top them up. JBL believes it has an alternative, though, and it's asking for your help to make it a reality. The Harman brand is crowdfunding Reflect Eternal over-ear headphones whose solar power theoretically gives you "virtually unlimited" listening.
Solar energy 'breakthrough' could replace fossil fuels in some industries
If solar energy is truly going to take over from fossil fuels, it needs to be hot enough for not only generating power, but replacing industrial processes outright -- and even the 1,049F of the best solar concentrator systems wouldn't cut it. Heliogen, however, may have finally cracked that barrier. The Bill Gates-backed startup has successfully concentrated solar energy at "breakthrough" temperatures above 1,832F, making it toasty enough to replace fossil fuels for industrial tasks like producing cement or steel.
The UK likely got more power from renewables than fossil fuels last quarter
The UK generated more power from renewable sources than from fossil fuels in the third quarter of 2019. This is the first time that's happened since the UK opened its first public electricity-generating station in 1882. The findings, revealed in an analysis by Carbon Brief, speak to progress the country has made in transforming its electricity system over the past decade.
Tesla may open 'Centers' to get around pro-dealership laws
Tesla may be planning an end-run around state laws that bar direct car sales and protect dealerships. Electrek sources claim the automaker is planning to open "Tesla Centers" in major urban areas that would theoretically avoid legal trouble by focusing on the sale of energy, not cars. These large outlets would offer sales, service and delivery seven days a week, even in states where "blue" laws prevent conventional car dealerships have to stay closed on Sundays. The strategy would take effect in the fourth quarter of this year.
The Energy Observer is a boat that makes its fuel out of seawater
Energy Observer is a vessel powered only by energy that it generates itself, be it the onboard solar panels, wind turbines or a hydrogen fuel cell. It's a floating laboratory, PR stunt and clean-energy evangelist all at once, showing how the future of transportation could be. Halfway through its six-year journey around the world, the vessel stopped in London so we could learn what's happened since its voyage started.
'World's first' solar-powered rail line opens in the UK
Some trains in the UK are now running on a rail line powered entirely by a solar farm in what's said to be a world first. Around 100 panels are keeping the signaling and lights up and running on the track near Aldershot in Hampshire, and the project could be a precursor to solar-powered trains on the nation's network.
Walmart sues Tesla after solar panels catch fire at stores (updated)
So much for Tesla's renewed solar power efforts getting off to a good start. Walmart has sued Tesla after rooftop solar panels on seven of the retailer's stores caught fire, allegedly due to poor safety practices. Tesla supposedly didn't ground its electrical and solar systems properly, according to Walmart, and regularly sent inspectors who "lacked basic solar training and knowledge." Walmart also asserted that Tesla's panels were rife with visible defects.
Tesla's relaunched solar power efforts include $50 panel rentals
Tesla has relaunched its troubled solar power efforts, and that now includes an option that might be more affordable for some homeowners. The company has debuted a Rent Solar program that lets residents in six states (Arizona, California, Connecticut, Massachusetts, New Jersey and New Mexico) pay a monthly fee instead of making an expensive up-front purchase. You'll typically pay $50 per month ($65 in California), but Tesla will do all the hard work. There's no long-term contract -- Tesla is simply betting that you'll keep it for long enough for those fees to add up.
Hyundai’s first car with a solar roof is available in Korea
Last fall, Hyundai revealed plans to outfit its cars with solar panels. Now, its first car equipped with a solar roof is ready. The New Sonata Hybrid is available now in Korea, and it should arrive in North America soon.

California farmers are planting solar panels as water supplies dry up Sammy Roth, Los Angeles Times In parts of California, water is becoming scarce, and that's not great news for farmers. There is an alternative though: solar panels. Los Angeles Times explains how the renewable energy source might help replace jobs and revenue that are lost as over half a million acres are taken out of production in the San Joaquin Valley alone.
Lightyear One is a long and expensive solar-powered statement car
The Lightyear One is long. Really long. The length and sloping roof make sense, though, once you realize the entire vehicle is powered by the sun. Together, the roof and hood offer a staggering five square meters of integrated solar cells underneath a safety glass which, the company promises, is strong enough for a clumsy adult to walk on without making dents. I wasn't able to test this claim at the Goodwood Festival of Speed, unfortunately. But early in the morning, before the car-loving masses had shown up, I was able to sit and truly admire its unusual profile for a while.
UAE debuts the world's largest individual solar power project
The United Arab Emirates might still be associated with oil money, but it just set a record for reducing its dependence on oil. The Emirate Water and Electricity Company has started running Noor Abu Dhabi, the largest individual solar power project in the world. At 1.18 gigawatts of peak capacity, it's only eclipsed by solar parks (where multiple projects share space) -- it makes the US' biggest facility, the 569MW Solar Star, seem modest by comparison.
Rivian will repurpose used EV batteries for solar power in Puerto Rico
Rivian is known for pushing the boundaries of battery tech. Not only is the startup working on the first all-electric pickup for the US market, it's also planning "Rivian-to-Rivian" charging, which will allow its vehicles to charge each other, and it designed a camp stove add-on that takes advantage of the EV's battery pack. Now, the company wants to turn its used batteries into an energy storage system for a solar power microgrid in Puerto Rico.
America's renewable energy capacity overtakes coal for the first time
America's renewable energy capacity has overtaken coal for the first time ever. According to a report by the Federal Energy Regulatory Commission (FERC), the addition of new solar, wind and hydro capacity in the first four months of the year pushed renewable energy's share of total available installed capacity to 21.56%. Coal's share, meanwhile, has dropped to 21.55 percent, down from 23.04 percent last year.
Renewable energy is on the rise, but so is demand for fossil fuels
Recent reports from major climate organizations are painting a very mixed picture for the future of global energy use. The International Renewable Energy Agency (IRENA) says that renewable energy now forms one-third of the world's total energy capacity -- its highest level ever -- but at the same time, the International Energy Agency (IEA) reports that energy demand is growing at the fastest pace this decade, and fossil fuels are leading the charge.
China wants to put a solar farm in space by 2025
Humanity uses a lot of energy, and while solar power here on Earth is doing a reasonable job of contributing to the electricity mix, scientists have long hypothesized that gathering the sun's energy from space would be a lot more effective. And now China says it's going to be the first to do exactly that, announcing plans to build an interstellar power station that will orbit the Earth at 36,000 kilometers.
This portable, solar-powered oven was built for the apocalypse
One of the things I love most about CES is the array of fascinating gadgets I come across. I'm talking stuff that's not a smartphone or a laptop. Case in point: this portable, solar-powered oven. GoSun's Fusion electric stove has an integrated heating system that can heat up to 550 degrees Farenheit, making it capable of cooking a meal within 20 minutes, with only sunshine as fuel. The company says the Fusion is five times more efficient than a traditional oven, and claims it can cook food with the same amount of energy needed to power a lightbulb.
California gives final approval to code requiring solar on new homes
While there was little doubt it would happen, it's now a done deal: California will require solar panels on most new homes. Officials at a December 5th Building Standards Commission meeting have voted for the new code, providing the last bit of approval necessary for the policy to take effect. New homes, condos and low-rise apartments will need eco-friendly power generation on their rooftops from January 1st, 2020 onward. The only exclusions are for homes that are either blocked by taller objects (like trees and tall buildings) or don't have room for panels.
