According to the most recent issue of the “Monthly Energy Review” by the U.S. Energy Information Administration (EIA), renewable energy accounted for 11 percent of primary energy production during the first nine months of 2010 (the most recent period for which data have been released).
More specifically, renewable energy sources (biomass/biofuels, geothermal, solar, water, and wind) accounted for 10.9 percent of domestic energy production and increased by 5.7 percent compared to the same period in 2009.
Among the renewable energy sources, biomass and biofuels accounted for 51.95 percent, hydropower for 31.50 percent, wind for 10.52 percent, geothermal for 4.65 percent, and solar for 1.38 percent. Comparing the first three-quarters of 2010 against the same period in 2009, hydropower declined by 5.2 percent but geothermal expanded by 1.8 percent, solar grew by 2.4 percent, biomass/biofuels increased by 10.0 percent, and wind grew by 26.7 percent; combined, non-hydro renewables expanded by 11.5 percent.
Preliminary data also show that fossil fuels accounted for 78 percent of primary energy production. Overall, U.S. primary energy production rose by 2 percent compared with the first nine months of 2009.
The information in this report was obtained from a press release issued Dec. 27, 2010, by The SUN DAY Campaign, a non-profit research and educational organization founded in 1993 to promote sustainable energy technologies as cost-effective alternatives to nuclear power and fossil fuels.
The U.S. Energy Information Administration released its most recent “Monthly Energy Review” on December 22, 2010. It can be found at: http://www.eia.gov/emeu/mer/overview.html. The relevant charts from which the data above are extrapolated are Tables 1.1 and 1.2. EIA released its most recent “Electric Power Monthly” on December 17, 2010; see: http://www.eia.gov/cneaf/electricity/epm/epm_sum.html. The relevant charts are Tables ES1.A and ES1.B.
