Tesla closes solar installation centers as part of layoffs
Tesla's recently announced layoffs may hurt its solar panel business particularly hard. Reuters sources and leaked documents have revealed that Tesla is closing roughly a dozen solar installation centers in nine states as part of the job cuts. There will still be about 60 facilities left afterward, but this would also end a Home Depot partnership that was reportedly responsible for half of Tesla's sales in the category.
Nissan follows Tesla with an all-in-one solar storage package
After making strides in the electric car market, Nissan has set its sights on the home. The company recently debuted its redesigned Leaf electric car and continues to push its xStorage battery, but now it wants to combine its two great loves under one roof. That's what the Nissan Energy Solar scheme -- the company's complete home energy solution -- is all about.
Regulation has helped, not hindered California’s green economy
Earlier this year, California raked in $2.7 trillion gross state product, overtaking the UK as the world's fifth largest economy -- only Germany, Japan, China and the US itself produce more annually. It isn't just our lush farming regions or the technological wonders coming out of Silicon Valley that have made California an economic bellwether, the state's strict adherence to environmental regulations, which go far and above what the rest of the nation demands, have certainly helped as well.
California to require solar panels on most new homes
There's no question that solar power is entering the mainstream, but California is about to give it a giant boost. The state's Energy Commission is expected to approve new energy standards that would require solar panels on the roofs of nearly all new homes, condos and apartment buildings from 2020 onward. There will be exemptions for homes that either can't fit solar panels or would be blocked by taller buildings or trees, but you'll otherwise have to go green if your property is brand new.
SoftBank and Saudi Arabia to build world's biggest solar farm
SoftBank and Saudi Arabia have drawn up plans to build the world's biggest solar farm, which, if realized, would create 100,000 jobs in the kingdom and produce 200 gigawatts (GW) of energy. That's a third more than the global photovoltaic industry supplied worldwide last year.
Researchers improve spinach-based solar cells by adding blackberry dye
Biohybrid solar cells aren't nearly as efficient as standard silicon panels, but including natural materials in renewable energy could make it more cost-effective. Scientists have refined one design based on the proteins in spinach leaves by adding natural dye extracted from blackberries, a combination which apparently produces much more voltage than the greens alone.
Tesla Powerwall systems help some Hawaii schools beat the heat
Tesla shipped Powerwall batteries to Puerto Rico last fall -- and to Australia last December -- and now it's helping Hawaii. Again. Specifically, it supplied equipment to the island state to help schools combat Hawaii's tropical temperature and relative humidity. Roadshow reports that Tesla shipped some 300 batteries and solar panels to the island as a way of keeping schools cool using renewable energy. This was after state government challenged the local department of education to cool an additional 1,000 classrooms without bumping electricity usage.
Renault's 'smart island' runs on wind power and recycled batteries
Renault has launched a "smart island" in Portugal that uses its Zoe electric vehicle, home batteries, smart charging and vehicle-to-grid (V2E) energy storage to run without fossil fuels. The idea is to make the Madeira island of Porto Santo energy independent and stimulate renewable energy production. "[We want] to build a model that can be carried over to other islands and cities," Renault Electric Vehicle Director Eric Feunteun told Engadget.
Buzz Aldrin wants you to buy this $150 solar backpack
Buzz Aldrin: revered engineer, astronaut of our time and now, the face of high fashion backpacks. Bag brand Sprayground has released a new collection, "Mission to Mars", and the campaign sees Aldrin playing the role of a flight coach, modelling the collection's pieces as he hangs around Mars surrounded by attractive astronauts going about their space business. At the center of the collection is a limited edition solar backpack which comes with a power pack, so it's as useful as it is futuristic looking, which you'd expect for its $150 price tag. Aldrin has been increasingly vocal in recent years about his plans to get astronauts to Mars, so at least we know they'll look good when they get there.
Tesla will create 'virtual power plant' with 50,000 Australian homes
Tesla isn't done bolstering Australia's power grid just because its giant battery farm is up and running. South Australia premier Jay Weatherill has unveiled a partnership that will provide 5kW solar panels and Tesla Powerwall 2 batteries to "at least" 50,000 homes in a bid to create the largest-ever "virtual power plant," where homes contribute their surplus energy to the grid. The move will theoretically stabilize the Australian state's electricity infrastructure, reducing the blackouts and surging prices that have plagued the region in recent times.
The state of solar installers after Trump’s tariff
Two days after President Donald Trump signed hefty tariffs on imported solar panels, a five-man team was hauling slabs of them up the outside of a brownstone in Brooklyn's Sunset Park. In below-freezing January winds, they set up steel tilt racks on the roof to hold 16 panels and wired the system to a solar inverter, making the power usable in the house and able to feed back into the electrical grid. The team from Brooklyn SolarWorks, an installation company with 21 full-time employees, finished the job around sunset.
Nearly all new US electricity capacity was renewable in 2017
Renewable energy played an important role in the US last year... although you might not want to cheer too loudly. Data from both the Rhodium Group and the Energy Information Administration shows that solar and wind power represented 94.7 percent of the net new electricity capacity (15.8GW out of 16.7GW) added in 2017. However, that's mainly because fossil fuel power continued to fade away. Electrek noted that plant closures removed 11.8GW of utility-scale fossil fuel power from the equation -- this was more a testament to the decline of coal than a triumph for green tech.
Thieves swipe a portion of China's solar road
Solar roads have plenty of potential problems, such as damage and snow, but theft? Apparently that's a concern, too. China's Qilu Evening News reported that thieves carved out a small (5.9in by 73in) portion of an experimental road in Jinan on January 2nd, a mere five days after its December 28th debut. While it's tempting to suggest this was an accident, officials said the missing segment was "neatly cut," and didn't appear to have come loose on its own.
Solar windows use sunlight to retain a building's heat
A domestic property loses as much as 20 percent of its heat through windows. For big glassy commercial buildings, that figure is a lot higher, resulting in big heating bills and inevitable disputes among employees about the thermostat. But researchers have now found a way to turn ordinary windows into solar-powered heaters, using energy from the sun to boost window temperature by as much as 15 degrees Fahrenheit.
Solar car race kicks off 30th anniversary with a fresh challenge
It's a special moment in the history of clean energy: the 30th anniversary World Solar Challenge has begun. A total of 42 solar-powered cars (the largest field to date) left Darwin, Australia on October 8th to travel roughly 1,880 miles to Adelaide. The race officially lasts a week, but it's likely going to end considerably sooner for the front-runners -- the world record holders, Tokai University, took just under 30 hours in 2009. As it is, technical hiccups knocked out several competitors in the first day of racing.
Solar power is the fastest growing source of global energy
Solar power was the fastest-growing source of global energy last year, overtaking growth from all other forms, according to the International Energy Agency (IEA). The spurt is largely attributed to lower prices and changing government policies encouraging a shift away from traditional power sources, such as coal. China, for example, has played an important role in renewable energy's prominence, accounting for almost half of all new solar panels installed worldwide.
A huge solar flare temporarily knocked out GPS communications
On the morning of 6 September the sun let out two pretty sizeable burps of radiation. Both were considered X-class -- the strongest type of solar flare -- with one of them proving to be the most powerful since 2005. If a solar flare is directed at Earth, which these ones were, it can generate a radiation storm that interferes with radio and GPS signals. The biggest flare ever recorded, in 2003, was so strong it even knocked out NASA's solar measurement equipment. These recent belches weren't quite on par with that, but they were enough to jam high frequency radios and interfere with GPS systems for about an hour on the side of the Earth facing the sun. Put your hand over your mouth, sun! Rude!
800,000 low-income UK homes to benefit from free solar panels
One of the biggest ever green energy schemes in the UK is set to provide clean energy for as many as 800,000 low-income homes over the next five years, renewable energy provider Solarplicity has revealed. As part of a £160 million investment from Netherlands-based Maas Capital (part of the ABN AMRO Bank), the company will provide 100,000 households with free solar panels over the next 18 months and hopes to reach its target within five years.
Stanford toughens up cheap solar cells by mimicking insect eyes
While silicon solar panels are already providing electricity for a lot of homes and buildings, it doesn't mean researchers have stopped looking for better and cheaper alternatives. Case in point, a team of Stanford scientists working to make a cheaper photovoltaic mineral called perovskite a viable option for people who want to shift to solar. Perovskites are as efficient as silicon solar cells when it comes to converting sunlight into energy, but they're fragile and can deteriorate easily when exposed to the elements. The team had to find a way to make them more durable -- and they've found inspiration in the compound eyes of insects.
Audi will use solar panels to help power its future EVs
When you think of electric vehicles, you probably imagine Tesla's Supercharger, or gas station-like centers where you go to top off the voltage. There's another idea, though, that makes a lot of sense: sun energy. AltaDevices, a subsidiary of Hanergy that makes thin, flexible solar panels, is working with Audi to bring the power of solar to your car's sunroof. The first prototype should be developed by the end of this year.
