State Renewable Portfolio Standards (RPSs) are increasing the proportion of electricity generated by renewable sources in more than 20 U.S. states, according to a report published on June 14, 2006, by the Pew Center on Global Climate Change. States are using RPSs to spur economic development and create a reliable and diversified supply of electricity, as well as to reduce greenhouse gas emissions and conventional pollutants.
The Pew Center report, entitled Race to the Top: The Expanding Role of U.S. State Renewable Portfolio Standards, examines challenges and opportunities inherent in RPS policy design and implementation and finds:
- A high degree of bipartisan support is driving the rapid expansion of RPSs at the state level.
- Economic development and job creation emerge as drivers in virtually every state.
- States are grappling with issues such as electricity transmission capacity constraints, differential treatment of individual renewable sources, and facility siting concerns.
- The biggest challenge in the future will likely revolve around the need for interstate collaboration and dialogue.
RPSs are also one of the recommended policies in EPAÃ¢â‚¬â„¢s new Clean Energy-Environment Guide to Action, and are described in detail in Chapter 5 of the guide. The Guide to Action is available at http://epa.gov/cleanenergy/stateandlocal/guidetoaction.htm.
