Renewable Energy & Energy Efficiency

Worcester has been an active contributor to the solar growth in the region. Since 2012, more than 1,500 solar systems were installed in our city! In only 6 years, from 2011 to 2017, the City installed, and now owns and maintains, 15 solar installations on municipal properties, totaling over 10.5 Megawatt-DC in solar capacity, including the largest municipally owned solar farm (8.1MW) in New England on the top of the Greenwood Street landfill. Four more are expected to go live in the summer of 2022.

Municipal Facilities

In 2009, the City initiated a multi-year, multi-million dollar energy efficiency and renewable energy project for municipal buildings. The goal was to modernize municipal facilities and reduce energy use, costs and greenhouse gas emissions. By the time the project is completed (est. 2024), it will consist of 6 separate phases, including building energy efficiency work at 90+ buildings; 15 renewable energy installations (including New England's largest municipal solar farm); replacement of all municipal parking, parks and streetlights with LED fixtures; and more. The total project cost to date is $115 million with life-cycle savings estimated at $164 million - which means that for every dollar we invested we will save more than $1.50! As notable as the financial picture is, the environmental benefits are just as impressive - the City has reduced its electrical use by the equivalent of 4,400 Worcester homes (7%) for a year with "brown electricity" (i.e. from burning fossil-fuels).

Community

Massachusetts leads on the ACEEE State Energy Efficiency Scorecard with respect to state energy efficiency policies and programs that save energy and produce environmental and economic benefits. For example, through the Mass Save program, numerous Worcester properties received free home energy audits, as well as rebates and interest-free loans for energy efficient work and equipment.

Dismas House and the Commonwealth Green Low Income Housing Coalition have assisted over 40 properties and 19 housing nonprofits in Worcester and surrounding towns with energy upgrades, solar, insulation and heating so as to lower utility costs and reduce carbon output.

The Green Jobs Academy, with a location in Worcester, provides training in building science to individuals to enable them to enter and move up a career ladder in the building/weatherization industry.

Greenhouse Gas Emissions Inventory

Worcester's most recent Greenhouse Gas Emissions Inventory demonstrates the progress made due to our energy efficiency and renewable energy projects over the past 10+ years. From 2009 to 2019, GHG emissions associated with municipal operations decreased by 16 percent!

Green Community Program

Green Community LogoWorcester was one of 35 Massachusetts municipalities to be designated a Green Community in 2010. The City earned the Green Community designation by meeting five criteria relating to different aspects of reduction of energy use and promoting renewable energy:

  1. Renewable/Alternative Energy. Provide as-of-right* siting of renewable or alternative energy generating facilities, renewable or alternative energy research and development facilities, or renewable or alternative energy manufacturing facilities in designated locations. (*As-of-right means that the proposed land use does not require a discretionary permit from a Board in order to be located in a given zoning district.)
  2. Renewable/Alternative Energy Permitting. Establish an expedited application and permitting process under which these energy facilities may be sited within the municipality and which shall not exceed one year from the date of initial application to the date of final approval.
  3. Energy Use Reduction. Establish an energy use baseline inventory for municipal buildings, vehicles and street and traffic lighting, and put in place a comprehensive program designed to reduce this baseline by 20% within five years. View the chart below for details.
  4. Fuel-Efficient Municipal Vehicles. Purchase only fuel-efficient vehicles for municipal use whenever such vehicles are commercially available and practicable (with certain exemptions for police and public safety vehicles).
  5. Building 'Stretch' Code. Require all new residential construction over 3,000 square feet and all new commercial and industrial real estate construction to minimize, to the extent feasible, the life-cycle cost of the facility by utilizing energy efficiency, water conservation and other renewable or alternative energy technologies.

Better Climate Challenge

In early 2022, the City of Worcester joined the U.S. Department of Energy's Better Climate Challenge, committing to reduce our greenhouse gas emissions by at least 50% within 10 years. The Better Climate Challenge is a government platform that provides transparency, accountability, technical assistance and collaboration to identify decarbonization pathways and provide recognition for leadership across the US economy. At the time of joining, Worcester was one of only 15 municipalities across the nation to undertake this challenge and the first in Massachusetts to do so.
