Arizona implemented at least one new clean energy policy or incentive supporting renewable energy and energy efficiency in 2024, according to data from the Database of State Incentives for Renewables & Efficiency (DSIRE).
Since 2010, the state has adopted at least an additional 19 clean energy-related policies.
In 2024, Vermont led the nation with nine new measures, while Minnesota and six others states did not adopt any.
The Database of State Incentives for Renewables & Efficiency (DSIRE) is a comprehensive source of information on energy-related incentives and regulations across the United States. It is managed by the North Carolina Clean Energy Technology Center at North Carolina State University and offers one of the most detailed collections of data on renewable energy and energy efficiency programs.
DSIRE tracks programs offered by federal, state, and local governments, as well as those provided by investor-owned utilities and larger municipal or cooperative utilities. The database includes summaries of incentives available in U.S. territories and details a wide range of support tools—from tax incentives, grants, loans, and rebates to industry recruitment efforts and performance-based incentives.
In addition to financial incentives, DSIRE covers regulatory and policy information related to clean energy adoption. These include building energy codes, public benefit funds, appliance and equipment efficiency standards, and energy requirements for public buildings. It serves as a valuable resource for policymakers, researchers, businesses, and consumers seeking to understand and access clean energy opportunities nationwide.
The database is limited to incentives and policies offered by investor-owned utilities across the U.S., along with electric cooperatives and municipal utilities that serve more than 30,000 customers.
