HALLOWELL (AP) — Environmentalists and Democratic lawmakers are raising concerns about Maine utility regulator’s decision that would limit the amount of funding available for energy efficiency programs.

The Natural Resources Council of Maine and Conservation Law Foundation say the Public Utilities Commission’s 2 to 1 vote on Tuesday would essentially place a roughly $22 million limit on funding for Efficiency Maine, which supports programs designed to help lower their heating bills.

A spokesman for the panel didn’t immediately return a request for comment on Tuesday.

The environmental groups plan to ask the commission to reconsider its decision.

Michael Stoddard, executive director of Efficiency Maine, tells the Maine Public Broadcasting Network that if the decision stands, it would have to cut programs that help people pay for weatherization and high-efficiency heating systems.
