According to the U.S. Energy Information Administration
, one-third of the energy used in the United States in 2009 was consumed in five States: Texas, California, Florida, New York, and Illinois.
The organization's State Energy Data System includes estimates of energy production, consumption, prices, and expenditures broken down by energy source and sector for each of the 50 states.
The United States used 94,445.9 trillion Btu of energy in 2009, more than doubling since 1960, the first year covered in this year's report.
Tennessee ranked 15th in total energy consumption for 2009, using 2136.0 trillion Btu or 2.3 percent of the nation's total. The state used 2.1 percent of national energy in 1960.
Renewable energy use in the United States:
Geothermal - increased from 2 trillion btu in 1965 to 200 trillion btu in 2009
Solar - increased from 55 trillion btu in 1989 to 98 trillion btu in 2009
Wind - increased from 22 trillion btu in 1989 to 721 trillion btu in 2009
Fuel Ethanol - increased from 7 million btu in 1981 to 910 trillion btu in 2009Renewable energy use in Tennessee
Most renewable use in Tennessee ranges from 0.1 trillion btu to 0.5 trillion btu. However, fuel ethanol has
had some ups and downs. Peaking at 4.9 trillion btu in 1988, the fuel fell steadily to 0 until jumping to 11.9 trillion btu in 2005. From there, it climbed to 26.4 trillion btu in 2009.
