An Act relative to building energy and decarbonization

This bill reorganizes the Department of Energy Resources into four specific divisions to better oversee energy efficiency, renewable energy, building decarbonization, and green community initiatives. It mandates that the department's council approve energy plans only if they align with state greenhouse gas emission limits and requires a two-thirds majority vote for these approvals. The legislation also establishes new definitions for district heating systems, energy storage, and microgrids while directing the council to prioritize underserved populations in its efficiency programs.
