In April, solar reached a new milestone, providing more than 2.3 percent of U.S. electrical supply, according to the latest issue of the U.S. Energy Information's (EIA) Electric Power Monthly, with data through April 30, 2017. Consequently, solar has now moved into third place among renewable sources — behind hydropower and wind but ahead of biomass and geothermal. . . . Renewables Provide More Electricity Than Nuclear Electric Power Monthly reveals that — for the first time since the beginning of the nuclear era — renewable energy sources (i.e., biomass, geothermal, hydropower, solar — including small-scale PV, wind) are now providing a greater share of the nation's electrical generation than nuclear power. For the first third of this year, renewables and nuclear power have been running neck-in-neck with renewables providing 20.2 percent of U.S. net electrical generation during the four-month period (January - April) compared to 20.75 percent for nuclear power. But in March and April, renewables surpassed nuclear power and have taken a growing lead: 21.6 percent (renewables) vs. 20.34 percent (nuclear) in March, and 22.98 percent (renewables) vs. 19.19 percent (nuclear) in April. . . .
