A very nice energy flow infographic for the US... (sadly Flash based, but the concept is good and a serious clean-up of most such charts)
The units are Quads (quadrillion BTUs), which are an artifact of how the source (LBL) tabulated the information. An ugly unit, but it has the virtue that the country uses about 100 Quads of energy a years, so the figures are close enough to percents of the total for most purposes. I would suggest an enhancement that would allow the user to select Quads, percent of total, average power (divide by time) in watts
per citizen.
