Earlier this month, the 30th World Solar Challenge kicked off in Darwin, Australia, with 42 competitors vying for victory. At the end of the 3,022-kilometer (1,880-mile) race from Darwin to Adelaide, one team emerged victorious in the highly contested Cruiser class. Solar Team Eindhoven, from the...

Although a car powered solely by solar power is far from reality, the 30th anniversary of the World Solar Challenge showcased just how far the technology has come. World Solar Challenge kicked off its celebrations with this year's iteration of the solar-powered car race in Darwin, Australia, on...

For years, renewable energy has been cast as the most expensive option to reduce emissions and the world's reliance on fossil fuels. But 2016 may have marked a turn for the renewable energy sector, with solar energy in particular rising significantly in output. For the first time in history...

For 50 years, the state of California has led the United States when it comes to renewable energy and electric cars. The state features many programs to incentivize electric-car ownership, and 29 percent of the state's 2016 energy production came from solar, wind, and other renewable power sources...

The notion electric cars will become a standard transportation option is slowly being accepted across multiple industries. It hasn't penetrated quite as much in the motorhome world, but now a German company has shown its interpretation of what the future of plug-in motor homes could be. It's called...

Solar power provides 10 percent of California's energy supply, which meant electric-grid operators had to be prepared for potentially disastrous effects during Monday's solar eclipse. To the surprise of many, there were no serious repercussions as the moon blocked a significant source of energy for...

The purchase of an electric car that plugs into the power grid to recharge its battery often gets drivers thinking about the source of their energy. We haven't seen data from recent years looking at the overlap between electric-car drivers and home solar panels. But early analyses in California...

The future of energy production remains in considerable debate, but some new research provides a more optimistic view for a lower-carbon future. Sources for new and replacement energy production remain uncertain, especially the degree to which renewable sources can replace those based on fossil...

The U.S. is coming up to its Independence Day holiday, in which we celebrate the Declaration of Independence from England and reflect on our history and traditions as a nation. This is an interesting time to do that, and there's a cynical argument to be made that backroom politics is as American as...

Scientists generally debate their studies and projections in relatively civil language, but perhaps the currently adversarial tenor of U.S. politics has spilled over into science. A 2015 study on the potential for renewable energy use in the U.S. has now produced not only a stringent attack, but a...

As Tesla regularly points out, the lithium-ion battery cells used in electric cars can also serve in home energy-storage units. Now, a Daimler company will go up against Tesla in that field under the branding of its most famous luxury-car make. Mercedes-Benz Energy announced yesterday that it is...

Half a century ago, the General Motors assembly plant was the largest employer in Fremont, California, and the town was known for its dragstrip. Today, that plant makes Tesla electric cars and Fremont is a part of the San Francisco Bay Area's Silicon Valley, creating advanced technology for the...

Cities across the U.S. are working to limit their emissions of climate-change gases turning to solar power, among other tactics. In 2016, programs focused on bringing the benefits of photovoltaic solar power to business and residents helped to expand that capacity with record-breaking growth...

Yesterday, U.S. president Donald J. Trump signed an executive order to begin the process of rolling back pretty much every vestige of U.S. efforts to address climate change. In both his campaigning and since his inauguration, Trump has claimed that his government and its actions focus on creating...

The new presidential administration seems poised to take a radically different approach to energy policy than its predecessor. That approach is founded on denial of accepted climate science, and an expressed desire to promote the fossil-fuel industry, including the so-called revival of coal. But...

No matter how you measure it, 2016 was a major year for solar energy. More solar-generating capacity was added last year than either natural gas or wind, according to the U.S. Department of Energy. A study by investment bank and research firm Lazard found that utility-scale solar has now become the...

The news on the renewable energy front continues to be good, with the costs of wind and solar generation falling steadily. By some measures, large-scale renewable energy is now cost-competitive (or close) with the most efficient natural-gas electric plants. Moreover, the amounts of clean generating...

Renewable-energy growth has accelerated in 2016, but this may go down as a milestone year for one renewable-energy source in particular. Together, all renewable-energy sources are expected to account for 8 percent of U.S. electricity-generation capacity in 2017, according to the Department of...

Unsubsidized utility-scale solar power is now cheaper than natural gas, according to new analysis.

Tesla and SolarCity collaborated on a renewable-energy project in American Samoa.
