Wind, Hydroelectricity See Bumps in New Chart of Americans’ 2011 Energy Use
A new analysis of American energy use in 2011 shows a shift to higher-efficiency technologies, though most energy use in the United States remains tied to coal, natural gas and petroleum (click here to see an enlarged version).
The flow chart analysis, which was released by Lawrence Livermore National Laboratory (LLNL), and was created using data from the Energy Information Administration (EIA), shows that Americans last year used 97.3 quadrillion BTU (quads), a slight drop from 2010.
The majority of energy use was for electricity generation, with wind power seeing the biggest jump between 2010 and 2011, increasing 27 percent. Hydroelectricity increased 26 percent. Livermore analysts attributed these changes to an increase in the number of wind farms
