Here is similar data from the EIEA: Primary Energy Consumption by Source and Sector http://www.eia.gov/totalenergy/data/annual/pecss_diagram.cfm I do not like this presentation as much. There are some interesting aspect of it. It shows significant changes over a short time. The 2007 version of this showed: Coal 22.8 quads Renewable Energy 6.8 quads This 2010 version shows: Coal 20.8 quads Renewable Energy: 8.0 quads Whoa. Figure F1 here is better: Primary Energy Consumption and Delivered Total Energy http://www.eia.gov/totalenergy/data/annual/pdf/sec17.pdf I do not find it separately broken out, but anyway this is better because it shows electricity as an intermediate. Here are conversion losses for electricity. A lot of room for improvement: http://www.eia.gov/totalenergy/data/annual/diagram5.cfm There are loads of great tables, graphs and spreadsheets here. - Jed
