Energy Flow

Thanks to a recent pitch by an entrepreneur, I saw this amazing chart from the US Government Energy Information Administration. The diagram shows sources and uses of energy in the USA in 2007.

In these times of nationalizing everything, finding out we have such a soviet-sounding bureaucracy is little comfort. However, this may be worthy of Tufte (or at least, in the right direction), so enjoy. Click on the picture to see the full size.

The units are quadrillion BTUs. Those Brits are everywhere (BTU = British Thermal Units).
