Get a better understanding of the environmental impact and operating costs of your current heating solution as compared to clean heating technologies.


This graph shows the carbon emissions produced by heating a standard 2,000 square-foot (SF) Massachusetts home using traditional as compared to clean technologies, assuming either today’s electric grid or a 100% renewable grid.

Greenhouse Gas (GHG) Emissions for Heating a Standard 2,000 SF Home

  • 2020 Electricity Grid
  • 100% Clean Electricity Grid
    • An individual homeowner can achieve a high percent of clean electricity today by installing solar PV and/or by purchasing electricity sourced from renewables.
    • To achieve Massachusetts’ Net Zero by 2050 goal, the utilities in Massachusetts will increase their purchase of clean electricity in the coming decades.


The graphs represent the annual heating operating cost for a standard 2,000 SF home heated by fossil fuels as compared to clean energy technologies.

*Please note that prices and performance may vary by year, system, and home weatherization level. Homeowners who install air-source heat pumps or ground-source heat pumps, which also provide cooling, can also expect to save 30% – 50% on cooling costs as compared to a standard central air-conditioning system.


There are a number of programs now available to homeowners, making clean energy solutions affordable to install.
