States Diversify Their Energy Mix


Twenty-Nine States Have Adopted Renewable Portfolio Standards and Goals

NCSL press release Denver—Currently 29 states, Washington, D.C., and three territories have been active in adopting or increasing renewable portfolio standards (RPS). These standards require utilities to sell a specified percentage or amount of renewable electricity.

Renewable energy policies help drive the nation’s $44 billion market for wind, solar and other renewable energy sources.

The National Conference of State Legislatures (NCSL) provides a state and territories breakdown of RPS or voluntary targets. This information is available through an interactive digital map as well as alphabetically.

This information, which is timely with NCSL’s Solar Energy Handbook release, highlights the following issues surrounding RPS:

  • Percentage of kilowatt hours requirement by year.
  • Applicable sectors.
  • Percentage-based cost caps.
  • Enabling statute, code or order
