MIDDLEBURY — A public forum about the future of the Vermont Yankee nuclear power station will be held on Monday, June 20, beginning at 7:30 p.m. at the Middlebury Congregational Church in downtown Middlebury. Sponsored by the Citizens Awareness Network (CAN) — a New England-based nonprofit dedicated to a renewable energy-focused economy — a panel of experts and activists opposed to nuclear power will outline how citizens can get involved with the shutting down and cleaning up of Vermont Yankee.
