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 Energy, and solar energy is responsible for most of... More solar energy was added in 2016 than natural gas or wind
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 Energy, and solar energy is responsible for most of... 
Over the past few years, the cost of electricity generation from renewable-energy sources has decreased dramatically. So much so, that renewable energy may have just hit an important milestone, according to one study. In the U.S., wind and solar power are now cheaper sources of electricity than natural gas—even without subsidies. DON'T MISS... 
The combination of Tesla and SolarCity is already promoting its potential synergies, albeit in a location far away from the mainland United States. The island of Ta'u in American Samoa is located more than 4,000 miles from the U.S. West Coast, and typically relies on imported diesel fuel to generate electricity. With no local sources of fossil... 
The overall carbon emissions associated with electric cars decrease as the electricity used to recharge them gets cleaner. And the latest statistics from the International Energy Agency (IEA) will be good news indeed for electric-car drivers. Last year saw record growth in renewable energy, according to the IEA, which surpassed coal to become the... 
While automakers work to meet stricter carbon-emissions standards, another sector of the U.S. economy has already made notable progress in reducing ts emissions. Carbon-dioxide (CO2) emissions from electricity generation during the first six months of 2016 were the lowest since 1991, according to the U.S. Energy Information Administration (EIA)... 
Over the past few years, China has made a major push to reduce carbon emissions by encouraging use of green technologies. Thanks to generous government incentives and fleet purchases, it is now the world's largest market for plug-in electric cars. Construction of new solar and wind farms has also proceeded at a rapid pace. DON'T MISS: Chevy Volt... 
The word "contagious" is often used to describe diseases, but not all contagions are necessarily bad. Studies have found that solar panels can be "contagious," for example. In other words, a homeowner is more likely to install solar panels on their house if their neighbor has done so. CHECK OUT: Electric Cars Vs. Solar Panels: Which One's The...
