The Community Sustainability Energy Cooperative (CSEC) was formed for the benefit of residents in Arlington, Bedford, Concord, Lexington, Winchester, Waltham, Lincoln, and Burlington with the goal of simultaneously lowering energy costs and carbon footprint.

We accomplish our goals by searching for and researching potential “Green” products and services, validating with experts the benefits, informing our members of the opportunities and then negotiating buying arrangements when possible to take advantage of our collective purchasing power.
