Berkeley Lab Examines State-level Renewables Portfolio Standards Policies

Berkeley, CA

More than 50-percent of non-hydro renewable capacity additions in the U.S. from 1998 through 2007 occurred in states with RPS policies, and 93-percent of these additions came from wind power.

Existing state RPS policies, if fully achieved, would require roughly 60 GW of new renewable capacity by 2025, equivalent to 15-percent of projected electricity demand growth.
