The estimated U.S. energy use in 2008 equaled 99.2 quadrillion BTUs (”quads”), down from 101.5 quadrillion BTUs in 2007. (A BTU or British Thermal Unit is a unit of measurement for energy, and is equivalent to about 1.055 kilojoules).
Energy use in the industrial and transportation sectors declined by 1.17 and 0.9 quads respectively, while commercial and residential use slightly climbed. The drop in transportation and industrial use – which are both heavily dependent on petroleum – can be attributed to a spike in oil prices in summer 2008.
Last year saw a significant increase in biomass with the recent push for the development of more biofuels including ethanol.
“This is a good snapshot of what’s going on in the country. Some of the year-to year changes in supply and consumption can be traced to factors such as the economy and energy policy,” said A.J. Simon, an LLNL energy systems analyst who develops the energy flow charts using data provided by the Department of Energy’s Energy Information Administration.
