Marc Breslow is easily one of my region's leading energy lights. We share a hometown, but the breadth of his influence really struck home for me a month or so ago when I attended Mass Energy's annual meeting. In a room full of trail blazers and luminaries, I don't think anyone prompted more references from the podium, including from state energy secretary Ian Bowles, than Marc. 

He is also a founder, or perhaps the founder, of Sustainable Arlington, a grassroots effort to make our town more energy efficient.

And, he gives seminars on how individuals can cut their home energy costs. The first in a new series is next week in Arlington, and three others are to follow:
