The map is a visual summary; every value is in the table below, which is the keyboard and screen-reader path. Groups are quintiles of the values shown (a derived grouping). Boundaries: Natural Earth (public domain), simplified. Alaska and Hawaii are shown as insets, not to scale.

Rank is derived by Quadranac: 1 = highest value; ties share a rank. The ranked value is itself derived; see the source table for the method. Values are as published in the source table.

Note: Shares are of net generation by all producers in the state (utilities, independent power producers and industrial and commercial plants), derived by Quadranac from EIA's annual state data. Electricity generated in one state is often used in another.
