Today's visualization is the summary of energy consumption for 2017, but you can see previous years going all the way back to 2010 on their website.
DEALING IN QUADS
As Visual Capitalist's Jeff Desjardins explains, the first thing you'll notice about this Sankey is that it uses an unfamiliar unit of measurement: the quad.
Each quad is equal to a quadrillion BTUs, and it's roughly comparable to the following:
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
