LLNL, which tracks U.S. consumption of energy resources, reported that wind power saw the biggest gains, reaching a total of 1.36 quadrillion Btu (quads) produced in 2012 compared to 1.17 quads in 2011. New wind farms continue to come on-line with bigger, more efficient wind turbines to generate electricity. Solar energy jumped from 0.158 quads in 2011 to 0.235 quads in 2012, spurred by declines in prices of photovoltaic (PV) panels, the report said.
Overall, the United States used an estimated 95.1 quads in 2012, which was 2.2 quads less than the previous year. The most energy was used for electricity generation, followed by energy used in the transportation, industrial, and residential sectors. Last year, energy use in the residential, commercial, and transportation sectors decreased while industrial energy use increased slightly.
