The New York Times has a series of graphs that show how each state produced its electricity from 2001 to 2017, by percentage of power produced from each energy source.
Why is this important on to a site about water footprints? Because we account for the water footprint of energy in our calculations of your water footprint with our Water Footprint Calculator. We ask which state you live in and whether or not you use conventional power or generate your own with solar or wind power.
These graphs perfectly illustrate how the generation profiles vary by state. If your state is big on thermoelectric power or hydropower, then your water footprint is likely higher than that of someone who lives in a more solar- or wind-friendly state, both of which use very little water to produce power.
