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

Savor the Savings: Energy Wisdom and Local Flavors

March 6th 2026 | 6:30 pm - 8:30 pm

REGISTER HERE

Join LexCAN and Lexington HeatSmart on Friday, March 6, from 7:00–8:30 PM at the Lexington Community Center Dining Room for a free Dine & Learn community buffet featuring food from a local restaurant for Lexington Chinese Speaking residents.

Learn how to save money and help the environment by taking advantage of Mass Save incentives for energy and fuel costs, insulation, heat pumps and more. After the presentation, you’ll have the chance to speak one-on-one with HeatSmart advisors about your specific home and where you are on your clean energy journey.

This event also marks the launch of a new Mandarin-language HeatSmart offering. Native Chinese speakers who would be more comfortable learning about clean energy and weatherization programs in Mandarin are warmly encouraged to attend. Though the event will be in Mandarin, english-speaking advisors will be present.

Free to attend, but registration is required so we can order the right amount of food. Capacity is limited to 80 guests.
