• Energy Efficiency for Businesses & Institutions

    Energy efficiency is a proven investment for small and large businesses, industry, hospitals, schools, and other organizations. It can decrease costs, reduce energy pricing risks, engage your employees, and demonstrate responsible business practices. Since it costs a fraction of the price of generating power, it's now our "first fuel."
  • Energy Efficiency for Cities and Towns: Green Communities

    The Green Communities Division is the energy hub for the Commonwealth's 351 cities and towns, providing energy efficiency and renewable energy resources and services.
  • Energy Efficiency in State Government Operations

    Massachusetts state government has made energy efficiency an essential focus in the buildings and fleets it owns and operates, as a demonstration of energy and environmental leadership. This focus is yielding energy and cost savings, greenhouse gas emissions reductions, and enhanced comfort in state buildings; it is Leading by Example.
  • Energy Efficiency for Your Home

    In Massachusetts, you have access to services and incentives to manage your energy use and control the cost of heating and cooling your home and running your appliances, and apply technologies. One smart choice is to start with an energy assessment, through Mass Save’s® online tool or website. DOER is also developing a residential energy pilot program launching later this year. See more options below:
  • Policies and Regulations for Energy Efficiency

    Landmark energy efficiency targets have been set for the next three years for electricity and natural gas savings in Massachusetts. They are expected to reduce energy waste, create customer savings, and stimulate the clean energy economy by creating jobs and innovation.
  • Building Rating & Labeling

    Unlike a car's miles-per-gallon (MPG) rating, there is no energy label to inform you about energy use when you buy a house or lease an office. DOER is collaborating with partners to pilot building energy ratings and establish related, common sense labels for both residential homes and commercial office buildings. 

  • Peak Demand Reduction Grant Program

    The Peak Demand Reduction Grant Program is a $4.68 million DOER initiative designed to test strategies for reducing Massachusetts’ energy usage at times of peak demand. $1.975 million was awarded to fund projects designed to defer investment in energy transmission and distribution systems. An additional $2.71 million will be used to fund projects designed to address all aspects of peak demand reduction including transmission and distribution investment, wholesale capacity markets, and customer demand charges.

  • Zero Net Energy Buildings (ZNEB)

    Commercial and residential buildings are major contributors to greenhouse gas emissions. Buildings consume 40 percent of primary energy used annually in the United States and 54 percent of energy used annually in Massachusetts. Our state is working to transform energy use in old and new buildings, moving toward super-efficiency and zero net energy renovation and construction, efforts critical to slowing the harmful progress of climate change.
  • ReBuild Western Massachusetts

    Tornadoes touched down in several communities in Western Massachusetts on June 1, 2011. The ReBuild Western Massachusetts program provided millions of dollars in financial assistance to help those residents impacted by the storm rebuild using energy efficiency practices and renewable energy technologies.
  • Resources for Energy Efficiency Practitioners

    Local energy specialists provide the expert services and advanced products fundamental to achieving Massachusetts' ambitious goals for reducing energy waste and building a clean energy economy. These resources offer a variety of options to improve your career, business, and industry.
