Helping Residents Electrify Everything

LexCAN works closely with the Town of Lexington's sustainability team to create programs like Clean Heat Lexington.

Reducing Waste and Protecting Ecosystems

We work closely with many local partners like LexZeroWaste, Lexington Living Landscapes, and many more organizations for maximum impact.

Advocating for Policy Change

LexCAN has helped turn climate ideas into town bylaws — including the nation’s first gas-powered leaf blower ban and a law banning fossil fuels in new home construction. Advocacy isn’t just talk.

Trusted by local climate leaders

Bill McKibben, Senator Mike Barrett,  Kerry Emanuel, and Maggie Peard share their support for LexCAN

Why are my Energy Bills so High?

March 1st 2026 | 4:00 pm - 5:30 pm

This session will help you understand your electricity and fuel bills, including supply rates, delivery charges, and all those confusing line items. You will gain clarity about what you are paying for and learn how to spot errors or improper charges. We will address how to identify those “too-good-to-be-true” predatory energy offers in the mail. We will provide actionable steps so you can take advantage of available discounted rates and incentive programs to lower your bills and transition to cleaner, cheaper forms of energy.
