Anaerobic Digestion

Through the Clean Energy Results Program, MassDEP is working with DOER, MassCEC and other partners to promote the diversion of organic material from landfills and incinerators to anaerobic digesters through regulatory streamlining, project siting, and broad education efforts.

Wind Turbines

Wind energy is fueled by an infinitely renewable resource - moving air. Learn more about the active role MassDEP has taken with its state partners to address public health concerns (including noise) that have been raised associated with the siting of wind turbines in Massachusetts communities.


  • Siting Clean Energy on Closed Landfills

    MassDEP is working to promote the appropriate siting of clean energy on closed landfills. The goal is to achieve 50 megawatts of clean energy (including solar and wind) on environmentally challenged property by 2020.  This will help meet the Renewable Energy Portfolio Standard (RPS) Solar Carve-Out target of 400 megawatts of solar photovoltaic (PV), creating green jobs and tax revenue benefiting Massachusetts communities.

  • Solar Carve-Out / SREC I
    Beginning in January 2010, the Department of Energy Resources (DOER) carved-out a portion of the RPS Class I Renewable Energy requirement to support distributed solar photovoltaic (PV) energy facilities, as provided by the Green Communities Act of 2008. Statement of Qualification Applications from facilities seeking qualification under the program were accepted through April 25, 2014.
  • Solarize Massachusetts - MassCEC

    Working in partnership with the state's Executive Office of Energy and Environmental Affairs, MassCEC is maximizing the environmental and economic benefits of renewable energy for the citizens, businesses, and communities of the Commonwealth. MassCEC has supported more than 2,000 projects in more than 275 communities with funding from the MassCEC's Renewable Energy Trust fund, which was created through the Electric Utility Restructuring Act of 1997, and is funded by an electric utility surcharge.

  • Renewable Energy: Solar - DOER

    The sun's rays supply an abundant amount of solar energy, which can be converted into electricity or heat. It has many benefits: solar energy is free and does not add to the production of global greenhouse emissions, acid rain, or smog. Also, the cost of solar energy technology has been decreasing significantly as the technology and market mature globally and within Massachusetts. The Commonwealth's goal is to achieve 250 MW of solar power installations by 2017.


  • Hydropower

    Hydropower is the use of energy in flowing water to power systems such as mills for grinding or tooling or spinning a turbine/generator system to produce an electrical current.

  • Commonwealth Hydropower - MassCEC

    The Commonwealth Hydropower Program seeks to increase the output of the Commonwealth's hydropower assets by providing grants for ecologically-appropriate projects that can be implemented quickly and efficiently.

  • Low Impact Hydropower Institute

    The Low Impact Hydropower Institute (LIHI) is a non-profit 501(c)(3) organization dedicated to reducing the impacts of hydropower generation through the certification of hydropower projects that have avoided or reduced their environmental impacts pursuant to the Low Impact Hydropower Institute's criteria.

  • Federal Energy Regulatory Commission

    The Federal Energy Regulatory Commission, or FERC, is an independent agency that regulates the interstate transmission of electricity, natural gas, and oil. FERC also reviews proposals to build liquefied natural gas (LNG) terminals and interstate natural gas pipelines as well as licensing hydropower projects.

Sustainable Biomass

  • Final Biomass Regulations - DOER

    The final regulation follows over two years of evaluation, public input, and careful considerations of how best to utilize woody biomass resources for energy, in a manner which is consistent with the Commonwealth's commitments to reduce GHG emissions and to protect the broad range of human and ecological services of the forests.

  • Biomass Renewable Energy - EEA

    Biomass includes a variety of versatile renewable fuel sources derived from organic plant and animal material, such as wood, crops, landfill gas, solid waste, and alcohol fuels. These locally produced resources can be used to generate electricity, provide heat, and develop alternative transportation fuels.

  • Massachusetts Renewable Heating Cooling Study - DOER links to PDF file

    We welcome this comprehensive and concise overview of the renewable heating and cooling industry in Massachusetts. The report illustrates that the market for solar hot water on our rooftops, efficient pellet boilers and heat pumps in the Commonwealth is growing and has the potential to take off.

  • Best Available Control Technology (BACT)

    Before approving a Limited Plan Application (LPA) or Comprehensive Plan Application (CPA), MassDEP must determine the best available air pollution control technology (BACT) for the proposal.
