The venture, called Nissan Energy Solar, allows homeowners to generate, store and charge EVs with their own renewable energy, which can reduce household energy bills by an estimated 66 percent, the company touts.

Since switching on in December, Tesla's massive battery in South Australia has already drastically lowered prices in the region's frequency and ancillary services market (FCAS) and has taken a major share of that market, Renew Economy reported.
During Australian Energy Week, McKinsey and Co. partner Godart van Gendt boasted about the stunning efficiency of the 100-megawatt Powerpack system, which is connected to Neoen's Hornsdale wind farm.
Kimbal Musk's nonprofit organization, The Kitchen Community, is expanding into a new, national nonprofit called Big Green, to build hundreds of outdoor Learning Garden classrooms across America.
Learning Gardens teach children an understanding of food, healthy eating and garden skills through experiential learning and garden-based education that tie into existing school curriculum, such as math, science and literacy.

Facebook announced Tuesday it will slash greenhouse gas emissions by 75 percent and transition global operations to 100 percent renewable energy by the end of 2020 in efforts to "help fight climate change."
When Angad Daryani was a child in Mumbai, he used to suffer from the air pollution there. "Growing up, I had asthma," he told CNN in a profile Wednesday. "I used to have a lot of breathing problems growing up in India."
Now, at the ripe old age of 19, he is working on an invention that could filter pollutants from the air of city skies and help other children breathe easier.

As electric cars and trucks appear increasingly on U.S. highways, it raises the question: When will commercially viable electric vehicles take to the skies? There are a number of ambitious efforts to build electric-powered airplanes, including regional jets and planes that can cover longer distances. Electrification is starting to enable a type of air travel that many have been hoping for, but haven't seen yet—a flying car.
Once finished, the 70-megawatt system will be the largest in the world by far; the current record-holder is the comparatively shrimpy 11.5-megawatt array in India that can power 8,000 homes.

The future of the auto industry is increasingly likely to be electric—although you wouldn't necessarily know that from sales numbers. Just under 200,000 plug-in cars were sold in the United States last year (out of a new-car market of 17.25 million). In California, cars with plugs made up 4.6 percent of the new-car market in 2017, while nationwide the number increased only slightly, to 1.16 percent of total auto sales. But 2018 is shaping up to be better, with 36 percent higher EV sales in the first four months than in the same period the previous year.
"Let's talk," the governor tweeted to Musk Thursday evening. "Do you want to show the world the power and scalability of your #TeslaTechnologies? PR could be that flagship project."

Elon Musk has a plan, and it's about as audacious as they come. Not content with living on our pale blue dot, Musk and his company SpaceX want to colonize Mars, fast. They say they'll send a duo of supply ships to the red planet within five years. By 2024, they're aiming to send the first humans. From there they have visions of building a space port, a city and, ultimately, a planet they'd like to "geoengineer" to be as welcoming as a second Earth.
If he succeeds, Musk could thoroughly transform our relationship with our solar system, inspiring a new generation of scientists and engineers along the way. But between here and success, Musk and SpaceX will need to traverse an unbelievably complex risk landscape.
The system—the largest of its kind on planet Earth—was tested twice just this month. According to CleanTechnica, on Dec. 14, the Loy Yang coal power plant in the neighboring state of Victoria suddenly went offline. Remarkably, the Hornsdale Power Reserve battery system (the Tesla system's official name) kicked in within 140 milliseconds and injected 100 megawatts of power into the grid.
After deploying a solar and battery system to a children's hospital in San Juan this October, Tesla has installed six more similar systems to help power the hurricane-wrecked islands of Vieques and Culebra in Puerto Rico.
In a statement to Bloomberg, Governor Ricardo Rossello's office said that Tesla installed the new units as “a humanitarian effort."
South Australia officially activated the world's biggest battery on Friday. The feat was achieved much to the credit of Elon Musk, who made a daring bet to “get the system installed and working 100 days from contract signature or it is free."
Musk was responding to a challenge from Australian billionaire Mike Cannon-Brookes to help fix the Australian state's electricity woes. Losing the bet would have cost the Tesla CEO "probably $50 million or more."
