AUGUSTA — Offshore wind will be a hot topic this December in Maine.

On Wednesday, Maine unions, port officials, manufacturers and environmental groups plan to release a report that tallies the region’s clean energy potential offshore and identifies major opportunities for economic, environmental and energy benefits from offshore wind.

It’s prepared by the National Wildlife Federation and co-sponsored by more than 35 organizations along the Atlantic Coast.

On Dec. 14, an offshore wind conference will take place in Belfast. Organizers say the conference will help coastal stakeholders weigh the related costs and benefits of offshore wind development in Maine.

The Island Institute, Maine Coastal Program, Maine Sea Grant, Gulf of Maine Research Institute, Manomet Center for Conservation Sciences and the Quebec-Labrador Foundation will lead panel discussions and breakout sessions.
