Solar power installations doubled in 2016 over 2015, as more and more areas of the United States began pulling their power from the sun.
For the first time, solar power installations formed the largest group of electricity generating capacity of any energy source, according to a new report from Greentech Media.
Nearly 40 percent of new power generation projects added last year were solar, in terms of electrical production capacity. A record 22 states each added more than 100 megawatts, the report said.
