Illinois has made major progress towards a clean energy future over the last several years, but its journey to clean, affordable heat is just beginning. The state’s landmark energy bill, the 2021 Clean and Equitable Jobs Act (CEJA), was a major victory for decarbonizing the electric grid, though it did not directly address or create new policies aimed at decarbonizing heating systems. On this front, more work is needed to fully achieve 100% clean across the electric and building sectors. The good news is that key regulators, thought leaders, and decision makers in Illinois have already gotten started on grappling with this complex topic.
