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, renewable energy sources accounted for fully two-thirds... Two-thirds of world’s new energy capacity in 2016 was renewable: IEA
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, renewable energy sources accounted for fully two-thirds... 
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. California is now preparing for a future in which...

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 the Dethleffs e.home concept and it envisions a... 
Solar energy has long generated electricity both on building roofs and in huge "solar farms" for utility companies, but only a few cars have had solar panels on their bodies. Solar roofs aren't a new concept, but Audi and Alta Devices' solution would be the most transparent photovoltaic solar roof implementation yet—literally. The German... 
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 many California utility companies. The solar... ![Photovoltaic solar panel installation on house, Fremont, California [image: Shiva Singh]](http://images.hgmsites.net/tmb/photovoltaic-solar-panel-installation-on-house-fremont-california-image-shiva-singh_100615724_t.gif)
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 indicated as many as four in 10 electric-car drivers... 
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 fuels. Even with the newer, optimistic predictions... 
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 apple pie and bald eagles. Which brings us to the... 
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 harsh rebuttal to that attack in language rarely... 
Here's a little quiz on a topic much discussed over the past couple of years: jobs. How many people work in the U.S. coal industry? Not just miners, but office staff, too. And, how many people work for solar-energy companies in the U.S.? DON'T MISS: Clean energy provides far more U.S. jobs than fossil fuels: analysis Coal mining was a mainstay of... 
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 working with Vivint Solar to develop home... 
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 world. The city has now taken another step into 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. Advances in solar technology, improved costs, and... 
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 while the White House prepares to execute what looks... 
Even before Elon Musk engineered Tesla's acquisition of SolarCity, the two companies were collaborating. SolarCity was already controlled by Musk, who believes its solar-energy business can be reinforced and complemented by Tesla's energy-storage business. Last year, Tesla announced a joint project with SolarCity to install a large battery farm... 
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 single cheapest form of unsubsidized electricity...
