Website: Database of State Incentives for Renewables and Efficiency

Established in 1995, the Database of State Incentives for Renewables & Efficiency (DSIRE) is an ongoing project of the North Carolina Solar Center and the Interstate Renewable Energy Council (IREC). It is funded by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE), primarily through the Office of Planning, Budget and Analysis (PBA). The site is administered by the National Renewable Energy Laboratory (NREL), which is operated for DOE by the Alliance for Sustainable Energy, LLC.

The DSIRE web site provides information about renewable energy and energy efficiency incentives and policies in effect in the United States. Relevant incentives and policies established by the federal government, state governments, local governments, electric utilities and non-profit organizations are included in DSIRE.

DSIRE provides the following information and resources:

National & Regional Policy Trends in Renewable Energy & Energy Efficiency

DSIRE’s Summary Maps provide a geographical overview of certain financial incentives and regulatory policies that promote renewable energy. DSIRE’s Summary Tables provide an overview of renewable energy and energy efficiency incentives and policies available in each state.

DSIRE Searches

The Search function on the DSIRE home page allows users to search all incentives and policies listed in DSIRE by one of five different criteria: state, incentive type, technology type, implementing sector or eligible sector. Searching by any of these criteria provides a list of applicable incentives and policies, with links to each program summary.
