The latest issue of the U.S. Energy Information's (EIA) Electric Power Monthly (with data through June 30) reveals that renewable energy sources (i.e., biomass, geothermal, hydropower, solar—inc. small-scale PV and wind) remain in a statistical dead heat with nuclear power vis-à-vis their respective shares of the nation's electrical generation, with each providing roughly 20 percent of the total.
During the six-month period (January — June), renewables surpassed nuclear power in three of those months (March, April and May) while nuclear power took the lead in the other three. In total, according to EIA's data, utility-scale renewables plus small-scale solar PV provided 20.05 percent of U.S. net electrical generation compared to 20.07 percent for nuclear power. However, renewables may actually hold a small lead because while EIA estimates the contribution from distributed PV, it does not include electrical generation by distributed wind, micro-hydro or small-scale biomass.
