EIA: “Coal and mid-continent crude oil (WTI) led energy commodity price declines in 2012. Natural gas was the only key energy commodity with a significant price increase when comparing January 1 to December 31. Heating oil, Brent crude oil, and wholesale gasoline (RBOB) ended 2012 close to the level at which they started the year. In 2012, average prices for crude oil and petroleum products were largely close to the 2011 averages, with some fluctuations throughout the year. Natural gas prices declined through the early portion of 2012 but then increased in the early fall and winter. Prices for Central Appalachian (CAPP) and Powder River Basin (PRB) coal declined at the beginning of 2012 and remained significantly below the average levels of 2011.”
