Renewable Electricity Standard Law and Legal Definition

A renewable electricity standard (RES) is a law requiring that a certain percentage of a state's or nation's electricity be generated from renewable energy sources.

States that stand to gain the most from a strong RES, according to the RES Alliance / Navigant Consulting study, include:

Louisiana, Alabama, Kentucky, Tennessee Georgia and Florida that can benefit from substantial biomass and municipal solid waste-to-energy

Ohio, Michigan, Pennsylvania and Indiana, which will gain from growth in manufacturing for a wide range of technologies

North and South Dakota, Iowa, Kansas, Nebraska and Illinois, home to major wind resources

Colorado, Arizona, Oregon and California, where solar, wind and hydropower have significant growth potential

States that do not currently have renewables standards or targets like Indiana, Florida, Virginia, Kentucky, Tennessee, Georgia, Arkansas, Oklahoma and Alabama

The study emphasizes that while tax credits continue to play a critically important role in preserving the viability of existing facilities, an RES is needed in order to support both near- and long-term investments.
