Energy Efficiency

Residents can take advantage of cash incentives and rebates available through the Mass Save Home Energy Services Program.  The Mass Save program provides residents, both owners and renters, with a no-cost home energy assessment.  You'll receive immediate savings from the assessment alone, with the installation of energy-saving light bulbs, digital programmable thermostats, and water saving devices for your sinks and showers.

Your Mass Save advisor will also provide a list of recommended improvements subsidized by the program, which will allow you to cut your energy bills even further.

Chelmsford was awarded a grant by National Grid in April 2014 to conduct educational outreach on the Mass Save program, including free workshops and other information for residents. To participate in this program, please see the links and event info on the Chelmsford Saves page.

Energy Savings Opportunities:

  • If you replace 25% of your lights in high-use areas with compact fluorescent light bulbs, you can save about 50% of your lighting energy bill.
  • Modern washing machines use less water to get clothes just as clean, and spin faster, squeezing more water out and reducing drying time.
  • Water heating is the third largest energy expense in your home (after space heating and cooling).
  • ENERGY STAR® qualified appliances use 10% to 50% less energy and water than standard models.
  • Low flow showerheads and faucet aerators can reduce your hot water consumption by half.
  • The clothes dryer uses more electricity than every appliance after the refrigerator; consider using clothes lines on warm days.

Smarter House is a great new website from the non-profit ACEEE that provides information and tips on do-it-yourself home energy efficiency projects.

Compact Fluorescent Light (CFL) bulbs are about four times more efficient than standard incandescent bulbs. A 25-watt CFL will produce as much light as a 100-watt incandescent. Left on for 5 hours a day, it will save 135 kwh of electricity annually and prevent about 193 lbs of carbon dioxide emissions. CFLs contain trace amounts of mercury; learn how to properly cleanup a broken CFLLight Emitting Diode (LED) bulbs are even more efficient than CFLs, last longer, and contain no mercury, but are more expensive. Free LED and CFL bulbs are included in your Mass Save energy assessment.
