Boeing's solar-powered climate research drone takes flight in 2019
Aurora Flight Sciences, a subsidiary of Boeing that specializes in unmanned aerial vehicles, is gearing up to launch a solar-powered autonomous aircraft. The vehicle, called Odysseus, is designed for persistent flight at high-altitudes and will be used to perform climate and atmospheric research. Its first voyage is scheduled for the spring of 2019.
New solar cell generates hydrogen and electricity at the same time
In the ongoing pursuit of abundant, renewable alternatives to fossil fuels, scientists have produced hydrogen for fuel cells through artificial photosynthesis, which splits water into hydrogen and oxygen. Traditional processes have struggled to use optical, electronic and chemical properties in a way that makes this method efficient, but now researchers from Berkeley Lab have created a recipe that could completely bypass the limitations in current materials.
China bumps up renewable energy target to reduce reliance on coal
China, the world's biggest energy consumer, is stepping up its push into clean power with a revised renewable energy target. The nation is now aiming for renewables to account for at least 35 percent of energy consumption by 2030, whereas its previous target only stipulated "non-fossil fuels" making up 20 percent of energy use within the same time frame.
Renault is creating France's first 'smart island'
Back in February, Renault helped electrify the Portuguese islands of Madeira and Porto Santo -- a move not dissimilar to Tesla's efforts in Hawaii. Now it's at work again bringing power to the French island of Belle-Île-en-Mer, in a bid to create the first "smart island" in its home country.
Tesla's production problems extend to its solar roof business, too
The production problems Tesla has faced with its Model 3 have been well documented. Now, sources say the company is facing similar issues with its solar roof tile initiative. According to Reuters, former and current employees have revealed that assembly line problems, plus CEO Elon Musk's exacting aesthetic demands, has delayed production, causing tension with partner Panasonic, and rattling officials that are keen to see a return on significant state investment.
Liquid metal battery could lower cost of storing renewable energy
As dreamy as it might be to combine renewable energy sources with storage batteries, there's a problem: those batteries are expensive. It might take you years to recoup the costs. You'll be glad to hear, then, that Stanford scientists have a way to make those batteries more cost-effective. They've developed a liquid metal-based flow battery that can store electricity at a lower price, even on a large scale. A metal-producing mix of sodium and potassium serves as the negative side of the battery, providing nearly twice the maximum voltage of typical flow batteries (making them high-value) without having to resort to exotic chemicals or extreme temperatures.
Investment in renewable energy drops as fossil fuel use rises
Global investment in renewable energy is on the decline, according to the International Energy Agency (IEA). The energy watchdog says there's a significant contradiction between the statements governments make regarding their attitudes to renewables, and the tangible action being taken. Investment fell by seven percent to $318bn last year.
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.
