Wesson Energy

Watertown started Monday encouraging its residents to increase their energy efficiency by offering a food bank donation for everyone that signs up for a Home Energy Solutions audit.

Waterbury efficiency contractor Wesson Energy won its third U.S. Department of Energy Century Club Award in July, for improving energy performance in more than 100 houses in the past year.

Bristol residents who have their homes audited for energy efficiency will donate indirectly to two of the city's charities.
