Clean energy; define.

SB 2231 defines which energy sources count as "clean" for local government requirements on public utilities. It explicitly lists 18 permissible sources, including solar, wind, nuclear, natural gas, hydrogen, waste-to-energy, and geothermal, ensuring local governments (like cities or counties) cannot restrict utilities to only specific types. The bill applies to any political subdivision imposing clean energy rules on utilities, requiring them to accept any of the listed sources. It would have taken effect July 1, 2025, but died in committee in February 2025.
