All U.S. energy consumption in one giant diagram

This graphic is special type of flow chart, called a Sankey diagram…This particular one shows the total estimated energy consumption in the United States in 2015, and how energy flowed from source to the final destination. The graphic comes to us from the Lawrence Livermore National Laboratory and the Department of Energy.

The beauty of a Sankey is in its simplicity and and effectiveness. No information is left out, and we can really see the full energy picture from a 10,000 foot view.

❝ What’s a quad? It’s equal to a quadrillion BTUs, which is roughly comparable to any of these:

8,007,000,000 gallons (US) of gasoline
293,071,000,000 kilowatt-hours (kWh)
36,000,000 tonnes of coal
970,434,000,000 cubic feet of natural gas
25,200,000 tonnes of oil
252,000,000 tonnes of TNT
13.3 tonnes of uranium-235

It’s a lot of energy – and if you look at the diagram, you’ll see most of it is actually wasted.

Thanks, Barry Ritholtz
