Distribution of Energy Consumption by Source, 1973 and 2007 (percentage)
The Energy Information Administration revised the historical energy data series to include renewable energy in each sector. In transportation, the alcohol fuels blended into gasoline to make gasohol (10% ethanol or less) are now counted under “renewables” and have been taken out of petroleum. The petroleum category, however, still contains other blending agents, such as MTBE, that are not actually petroleum, but are not broken out into a separate category.
