Resources

This page collects reliable sources on clean energy, incentives, and siting. We check each source before we add it. The list will grow as members send more.

Incentives and policy

DSIRE, the Database of State Incentives for Renewables & Efficiency, lists the programs that pay for clean energy and efficiency. It covers federal, state, local, and utility incentives, and you can browse by state or search by ZIP code. The Massachusetts page includes the Renewable Portfolio Standard and the SMART solar program. The N.C. Clean Energy Technology Center at North Carolina State University has run the database since 1995.

Research and publications

The National Laboratory of the Rockies, formerly the National Renewable Energy Laboratory (NREL), is the federal government's renewable energy lab. Its solar publications page gathers the lab's work on photovoltaics, concentrating solar power, and grid integration, and a keyword-searchable database of the full research output sits behind it. The lab kept the NREL name until the Department of Energy renamed it in December 2025, so older nrel.gov links may no longer resolve.
