Mercedes-Benz and Vivint want to power your solar home
Tesla has been dominating home energy headlines in recent months, what with the release of its solar roof panels and residential batteries, but Elon Musk's company isn't the only one getting into the home energy game. Mercedez-Benz announced on Thursday that it is teaming with solar-energy company Vivint to develop an all-in-one solar/battery setup of its own.
Tesla's Solar Roof is available for pre-order
Tesla didn't quite fulfill its promise to start Solar Roof sales in April, but you thankfully haven't had to wait that much longer to pull the trigger. As of today, you can pre-order Tesla's stealthy solar power cells in textured or smooth variants ahead of the first US installations in the summer (2018 elsewhere). While the price will vary depending on your home, of course, the company estimates that a "typical" buyer will pay about $21.85 per square foot instead of $24.50 for a regular roof. Not that there will be much mystery regardless of what you pay -- Tesla is offering a cost calculator to figure out your real-world expenses.
Google is helping Germans go solar
Google's Project Sunroof is a way of combining the company's mapping data with information on how much sunlight hits your home. With it, people can work out if their abode gets enough radiation for them to consider investing in solar panels. Until now, the service was limited to the US but, from today, the system is rolling out to Germans similarly curious about adopting renewables.
Coal company plans Kentucky's biggest solar farm for old mine site
Amid the decline of coal power, one fossil fuel company is refurbishing one of its old strip mining sites as a solar farm. Berkeley Energy Group is setting up two sites in eastern Kentucky as test locations to see if the concept is feasible. Early estimates peg the farm's production at 50 to 100 megawatts, which would yield five to ten times more electricity than the largest existing solar facility in the state.
Researchers break efficiency record for consumer-friendly solar panels
Turning sunlight into power is a surprisingly tricky thing. Experiments in academia have created solar arrays that can capture up to 40-percent of the sun's energy and convert it to electricity, but consumer cells are notably less efficient. At best, silicon-based technology has a theoretical 29-percent efficiency ceiling -- meaning any consumer panel in the low 20s is doing pretty well. Still, we're inching ever closer to the technology's limit. Researchers at Kaneko corp recently announced that they've developed a silicon solar cell with a record-breaking 26.3 percent efficiency rating.
Google: 4 out of 5 US homes have solar power potential
A five kilowatt rooftop solar installation now costs just $12,500 on average after tax credits, and pretty soon, installing one might soon be a matter of re-tiling your roof. Whether it's right for you, however, depends in large part on how much sun your house gets. That's where Google's Project Sunroof comes in -- launched just two years ago, it has now surveyed over 60 million US buildings in 50 states. That means there's a good chance you can see the electricity production potential in your city, neighborhood and even specific house.
New US solar installations nearly doubled in 2016
Yes, the head of the EPA did display a staggering level of ignorance about climate change, but not everything is terrible. A report produced by GTM Research and the Solar Energy Industries Association says that solar power in the US had a blockbuster 2016. It's believed that 14,762 megawatts of solar capacity was installed in the year, almost twice as much as the 7,501 megawatts that were added in 2015.
Tesla's new solar energy station will power Hawaii at night
Renewable energy supplies are great because they produce power without filling the air with pollution. Yet, once the sun goes down solar panels become pretty useless. But Tesla and Hawaii have a solution that'll use the sun's rays both day and night using Powerpacks built at the Gigafactory.
A renewable planet is almost inevitable
When the leader of the free world denies climate change and fills his cabinet with like-minded individuals, it's hard not to panic. The world is, after all, hurtling toward an irrevocable ecological catastrophe that threatens all of our lives. There may be a reason to be slightly less pessimistic, however, thanks to the mechanics of the energy business. Shortly before leaving the White House, Barack Obama said that clean power had an "irreversible momentum," and it looks as if there might be evidence to justify his optimism.
China is now the biggest producer of solar power
You probably don't think of China as a clean energy champion given its frequent problems with smog and continued dependence on coal power, but you may have to rethink your views after today. The country's National Energy Administration has revealed that its solar power production more than doubled in 2016, hitting 77.42 gigawatts by the end of the year. The country is now the world's biggest generator of solar-based electricity in terms of capacity -- it doesn't compare as well relative to population (Germany, Japan and the US could easily beat it), but that's no mean feat for any nation.
