Renewable Portfolio Standard
A renewable portfolio standard (RPS) is a state policy that requires electricity providers to obtain a minimum percentage of their power from renewable energy resources by a certain date.
In Connecticut, the RPS requires that by 2010, 7% of power in the state will be from renewable resources. Currently there are 20 states plus the District of Columbia that have RPS policies in place. Together these states account for more than 42% of the electricity sales in the United States. Two other states, Illinois and Vermont, have non-binding goals for adoption of renewable energy instead of an RPS.
