WATERVILLE — Sustain Mid Maine Coalition’s annual meeting is scheduled for 8:30-10 a.m. Saturday, March 18, in the Silberman Lounge part of the Cotter Union at Colby College.

Stephen Kahl, associate professor of science and sustainability liaison at Thomas College, will be the keynote speaker.

Kahl is not affiliated with any specific energy company. His talk “The Business and Economic Case for Renewable Energy NOW” will focus on specific — and hopeful — information about transitioning to renewable energy.

Attendees can question Kahl, discuss energy issues and even become part of the solution if so moved.
