A former Tesla executive has joined Lightyear to help create a commercial strategy for the super-efficiency car.

Walmart sued Tesla on Tuesday, alleging that solar panels that Tesla installed on seven Walmart stores caught fire. The lawsuit accuses Tesla of breach of contract, negligence, and failing to live up to industry standards, according to the court filing. Walmart alleges that the fires resulted in...

The result of our recent poll suggest that many of our readers and followers do believe that putting solar cells on vehicles is a worthwhile pursuit.

Toyota is testing the potential of leading-edge solar cells from Sharp, which when placed on the rood, hood, and rear hatch of the Prius Prime might recover meaningful driving range.

A Dutch startup is making some highly optimistic claims about the range it might be able to regain from solar panels on its roof and hood.

Tesla CEO Elon Musk reaches a new settlement with the SEC to avoid contempt charges. We sat down with the chief engineer of the new 2020 Toyota Highlander Hybrid to learn how it reaches fuel-economy estimates similar to the compact Corolla. Some new infrastructure could help boost wind power in...

Updated to correct the total power output expected from the MTA rooftop project. Electric cars and public transportation go together in more ways than one. In the latest example, the New York Metropolitan Transportation Authority plans to add solar panels to the rooftops of its rail yards and bus...

Quirky electric hatchback that started as a crowdfunding campaign is now ramping up for production.

Concept cars are relatively easy to build—particularly concepts of cars that may exist only on paper or as clay and foil design studies. That has given rise to a host of new concepts launched as online crowd-funded endeavors of various levels of seriousness and potential. One is Sono Motors...

A longtime reader and plug-in car owner lays out an effective roadmap for going solar. Tesla and Electrify America reach an agreement to install Tesla stationary battery storage at some EA DC fast-charge stations. Mercedes-Benz joins the ranks of automakers whose diesel engines are involved in a...

As solar cells get more efficient, powerful panels can fit on smaller areas. For those looking to use renewable energy for transportation, that means solar panels can now move from home rooftops used to power car chargers to cars themselves. In Korea on Wednesday, Hyundai and Kia revealed some...

Electric cars and solar power fit together like a hand in a glove. Charging with solar power, electric cars can drive using almost no non-renewable energy. Now according to a report in Bloomberg New Energy Finance last week, solar investment has dropped by 19 percent worldwide in the second quarter...

Falling prices for lithium-ion batteries will enable half the world's electricity to come from renewable solar and wind by 2050. That still won't be enough to meet global climate targets, however. Those are the conclusions of a new report by Bloomberg New Energy Finance (BNEF), released today...

Over the years, we've noted the paucity of solid data on the intersection of home solar energy and driving plug-in electric cars. A California-only study from 2012 still gets quoted occasionally, and we continue to seek more recent and more comprehensive data. Out of a mix of curiosity and...

Drivers who buy an electric car that plugs into the power grid to recharge the battery often start to consider the source of their energy. A 2012 analysis from California, in the earliest days of modern electric cars, indicated as many as four in 10 electric-car drivers were already using or...

While Tesla may be the automaker most known for marketing home-solar equipment, it's actually not the only player on the block. Japanese automaker Nissan previously offered home-energy storage solutions in Europe, dubbed Nissan xStorage, that utilized cells recycled from Nissan Leaf batteries...

Renewable-energy generation costs are falling like photons onto a solar panel. By 2020, it's expected all types of renewable-energy generation will be able to compete with fossil fuels on cost. That's right: saving our environment will actually save electric utilities some money, too. DON'T MISS...

For much of last year, U.S. Energy Secretary Rick Perry pursued a plan that, in essence, would prop up the financially challenged U.S. coal and nuclear industries. His proposal, submitted to the Federal Energy Regulatory Commission last fall, provided financial subsidies to electric-generation...

Call it the Ikea mindset. On populated islands, space is at a premium, just like those stereotypical Swedish kitchens you see when you stroll through your local assemble-it-yourself retailer. That space restriction is a major reason fossil fuels remain a better power-generation option than...

Five years ago, an electric-utility think tank issued a dire warning to its members: Your century-old business model is ending. The continually falling costs of renewable energy generation, especially solar panels, would begin to erode utilities' business from its most profitable customers, the...
