For the third year running, renewable energy accounted for the majority of new utility-scale capacity additions in the United States. According to the U.S. Energy Information Administration, 24 gigawatts of new utility-scale generation were added in 2016, of which 63 percent was renewable energy, almost all of it wind and solar. Hydroelectric generation continued to be the largest annual source of U.S. renewable generation, the EIA noted, but is quickly ground to wind, which matched or exceeded hydro generation during several months in the fall. The news for coal was far bleaker. Once final numbers are in, coal’s share of total generation is expected to fall to 30 percent of the nation’s power mix.
