Renewables Now Provide 12 Percent of Domestic Energyby Staff
Clean Edge News, January 5, 2012
According to the most recent issue of the "Monthly Energy Review" by the U.S. Energy Information Administration (EIA), with data through September 30, 2011, renewable energy sources continue to expand while outpacing the growth rates of fossil fuels and nuclear power. For the first nine months of 2011, renewable energy sources (i.e., biomass/biofuels, geothermal, solar, water, wind) provided 11.95% of domestic U.S. energy production. That compares to 10.85% for the same period in 2010 and 10.33% in 2009. By comparison, nuclear power provided 10.62% of the nation's energy production in the first three quarters of 2011 -- i.e., 11.10% less than renewables.
Looking at all energy sectors (e.g., electricity, transportation, thermal), renewable energy output, including hydropower, grew by 14.44% in 2011 compared to 2010. Among the renewable energy sources, conventional hydropower provided 4.35% of domestic energy production during the first nine months of 2011, followed by biomass (3.15%), biofuels (2.57%), wind (1.45%), geothermal (0.29%), and solar (0.15%). On the consumption side, which includes oil and other energy imports, renewable sources accounted for 9.35% of total U.S. energy use during the first nine months of 2011.
Looking at just the electricity sector, according to the latest issue of EIA's "Electric Power Monthly," with data through September 30, 2011, renewable energy sources (i.e., biomass, geothermal, solar, water wind) provided 12.73% of net U.S. electrical generation. This represents an increase of 24.73% compared to the same nine-month period in 2010. By comparison, electrical generation from coal dropped by 4.2% while nuclear output declined by 2.8%. Natural gas electrical generation rose by 1.6%.
Conventional hydropower accounted for 8.21% of net electrical generation during the first nine months of 2011 - an increase of 29.6% compared to 2010. Non-hydro renewables accounted for 4.52% of net electrical generation (wind - 2.73%, biomass - 1.34%, geothermal - 0.40%, solar - 0.05%). Compared to the first three quarters of 2010, solar-generated electricity expanded in 2011 by 46.5%; wind by 27.1%, geothermal by 9.4%, and biomass by 1.3%.
