About Energy Classification
Energy type is based on publicly announced power sources, PPAs (Power Purchase Agreements), and operator sustainability commitments. "Mixed" facilities draw from a combination of grid power and renewable sources. Many operators have renewable commitments that do not yet match actual energy consumption. 91 facilities in the index have unconfirmed energy sources.
