Wind energy supplied 4.7 percent of the total electricity generated in the U.S. in 2015, enough electricity to supply the equivalent of all electricity demand in Colorado, Oklahoma, and Kansas. Solar energy, including utility-scale and distributed solar, generated 0.94 percent of all U.S. electricity in 2015. The emerging opportunities in American wind power will be on display at this yearâs WINDPOWER Conference & Exhibition in New Orleans, May 23-26.
One out of every 50 new jobs added in the United States in 2016 was created by the solar industry, representing 2% percent of all new jobs.

Over the next 12 months, employers surveyed expect to see total solar industry employment increase by 10 percent to 286,335 solar workers.
