A story from Reuters shows a list of the 29 states (plus D.C.) that have set minimum targets for the amount of electricity that their utilities must obtain from renewable sources. Five states have established voluntary requirements.
Known as the Renewable Power Standard (RPS), targets range from 33% (Maine) to 5% (Texas). Targets are not comparable between states, because states define "renewable" in various ways.
Maine and New York, for example, count large hydropower plants as renewable sources. Ohio views nuclear power as renewable.
The list was compiled by North Carolina State University and the Pew Center. For a map showing details of the RPS by state, click here.
