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's share of home solar has been sliding ever since its acquisition of SolarCity. Will the Solar Roof turn the trend around?

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...

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...

With the big upturn in electric-car adoption driven by the Tesla Model 3, incoming Kia and Hyundai options, and the highly competitive Chevrolet Bolt, many drivers will be moving to vehicles that will be primarily charged at home.

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...

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...

A majority of the photovoltaic solar panels used in the U.S. are imported from such countries as China, Malaysia, South Korea, Thailand, and Vietnam. Now, environmentalists and energy analysts worry that the new 30-percent tariff on solar-panel imports announced last Monday by President Donald...

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...
