What’s New?

Sustainable Energy temporarily suspended Clean Energy Program and Energy Star and Green Leasing Program grant applications in June 2022 to relocate and transition operations to the Department of the Environment for the new fiscal year. We expect to recommence processing grants soon and will keep you updated on changes. Thank you for your patience.


Sustainable Energy's objective is to provide reliable and environmentally sound energy solutions that enhance the quality of life of Prince George’s County residents’ while concomitantly maximizing energy savings. The program coordinates the County’s efforts to reduce the 3 C's of energy: Consumption; Cost; and Carbon emissions

ü  Reduce County-wide greenhouse gas (GHG) or carbon emissions by 80% below 2008 levels by 2050;

ü  Meet 20% of County government buildings electricity demand with distributed, renewable energy generation by 2022;

ü  Help grant recipients achieve at least 15% energy savings for energy efficiency projects and 10% energy savings for solar projects;

ü  Help grant recipients reduce energy consumption by 20% or greater for office buildings and multifamily dwellings.   




The County government has set forth actionable strategies in order to lead by example and help facilitate broad residents’ participation in becoming more energy conscious and efficient throughout the community. The following themes have emerged that inform selection of strategies and measures. 

Build on Existing Efforts

The County has already put in place several initiatives, programs, and policies that support efficiency and climate protection goals. The guiding laws, policies and plans seek to bring those existing County efforts together under one framework, suggest improvements or augmentations, and add new efforts where gaps exist.

Alignment with County Goals and Priorities 

The County has a responsibility to deliver high quality core services in a way that encourages economic development, creates jobs, and generally improves the quality of life for County residents.

Engage the Community

The development of far reaching solutions necessary to achieve significant GHG reductions will require coordinated and broad participation of residents, businesses, municipal governments and the other institutions that make-up Prince George’s County. This calls for significant outreach and communication efforts and the establishment of public/private partnerships to help build resilient communities.

Build Capacity in the Energy Sector

Sustainable Energy seeks to exemplify the nexus between energy, economic development, and job creation initiatives in the County. Staff work closely with the business community, including diverse suppliers and county-based businesses, to build an advance energy economy.


Energy Efficiency (Natural Gas Incentives Now Available), Solar PV, & Solar Water Heater Grant
The Clean Energy Program builds on Maryland and Prince George's County's energy-efficiency and carbon reduction goals and will help in making our County more energy resilient, using a holistic approach to break energy injustice and barriers. We offer residents within the Pepco service territory of these nine neighborhoods, classified as Energy Resiliency Communities (ERCs), the ability to apply for grants to perform energy efficiency retrofits and subsequently, install solar photovoltaic (PV) and/or water heater systems.

Presidential Policy Directive (PPD) 21 defines resiliency as "the ability to anticipate, prepare for, and adapt to changing conditions and withstand, respond to, and recover rapidly from disruptions". From an energy perspective, resiliency is the ability to prepare for and adapt to utility disruptions and recover quickly from these disruptions. It involves the deployment of distributed energy resources such as energy efficiency, renewable energy such as solar PV and thermal, battery storage, and microgrids. To learn more, selec

Energy Star Certification & Green Leasing Grant (Natural Gas Incentives Now Available)
Sustainable Energy provide grants to existing office and multifamily building owners that are Pepco and/or Washington Gas customers to perform energy and water efficiency retrofits, and also to obtain the US Environmental Protection Agency (EPA)'s Energy Star certification. Additionally, the building owners are to adopt various best practices in Green Leasing to motivate landlords and tenants to engage in energy-efficient practices.

Smart Energy Communities Policy & Action Plan

The Smart Energy Communities Policy and Petroleum Reduction and Renewable Energy Action Plan declare the County's intent to take a leadership role in reducing transportation petroleum consumption and increasing renewable energy generation by partnering with the Maryland Energy Administration (MEA) and enrolling as a Smart Energy Community. 

Climate Change

Sustainable Energy works closely with our regional partner, the Metropolitan Washington Council of Governments on various initiatives such as the development of the  regional and county-wide GHG emissions inventory. Prince George's County surpassed the regional 2012 goal, demonstrating that GHG reductions are possible even as the population and economy grows. As of April 2018, despite experiencing an 8% growth in population, GHG emissions reduced from 11.3 MMTCO2e (million metric tons of carbon dioxide equivalent) in 2005 to 9.9 MMTCO2e in 2015, representing an overall decrease of 12% within Prince George's County

Plan Prince George's 2035 - Energy Infrastructure Chapter

Plan Prince George's 2035 builds on the County's General Plan to help guide future growth, development, and public investments in the County. It establishes policies and strategies to encourage investment in energy infrastructure, renewable energy, and the use of smart grid technologies and promote the efficient use of energy resources. 


Clean Energy in County Government

Sustainable Energy has installed over 1MW of solar on government properties and will install an additional 4MW over the next 2 years. We’ve partnered with Prince George’s County Public School to install its first solar systems. Moreover, Sustainable Energy is working with various county agencies and utilities to install public-purpose electric vehicle charging stations on government properties.  Click here Transforming County Government to learn more about government clean energy projects.
