Energy - As enacted, clarifies that a political subdivision that imposes requirements or expectations related to the type of clean or green, or renewable, energy used by a public utility in an ordinance, resolution, or other regulation must include certain sources of energy as permissible sources of clean or green, or renewable, energy, regardless of whether the political subdivision classifies the requirements or expectations as relating to clean or green, or renewable, energy. - Amends TCA Title 4; Title 5; Title 6; Title 7; Title 13; Title 64; Title 65; Title 67 and Title 68.

HB 1143 clarifies that local governments (counties, cities) cannot restrict public utilities from using certain energy sources when creating regulations about clean or renewable energy. It requires all local energy requirements to include 19 specific sources as permissible, including solar, wind, nuclear power, natural gas, and biomass - regardless of how the local rule is worded. This directly affects municipal and county regulations governing utility energy sources and ensures utilities can comply by using any of the listed options. The bill amends multiple Tennessee code sections to define "clean or green energy" broadly and makes local rules that exclude these sources legally invalid.
