Renewable Portfolio Standards
A renewable portfolio standard is a state policy that requires electricity providers to obtain a minimum percentage of their power from renewable energy resources by a certain date. Currently there are 33 states plus the District of Columbia that have RPS policies in place. Together these states account for more than half of the electricity sales in the United States. Five other states, North Dakota, South Dakota, Utah, Virginia, and Vermont, have nonbinding goals for adoption of renewable energy instead of an RPS. More detailed data has been published by the Database of State Incentives for Renewable Energy (DSIRE).

Communication with Policy Makers
On May 10, 2013, researchers from the RenewElec project gave a briefing to congressional staff members. A policy-maker guide has also been published and can be found here.
One March 2, 2011 the RenewElec project submitted comments to the Federal Energy Regulatory Commission on Integration of Variable Energy Resources Notice of Proposed Rulemaking. The comments can be found here.
