The United States gets its electricity from a complex mix of sources — coal fired power plants, gas plants, hydroelectric dams, wind and solar installations, and much more.

The Clean Power Plan, soon to be finalized by the Obama administration, will shift the mix — in favor of renewable sources and to some extent natural gas, and away from coal.

In the quiz below, we show the different distributions of a given electricity source across the country, and then ask you go choose which source it is. See how you do — the best possible score is a 7.
