Harnessing Maryland’s Renewable Energy Potential
As Maryland continues to lead the way in renewable energy adoption, geothermal energy has emerged as a sustainable and cost-effective solution for homeowners and businesses alike. To encourage the adoption of this clean energy source, Maryland offers Geothermal Energy Credits that help offset installation costs while promoting energy efficiency.
This guide provides a comprehensive overview of Maryland’s Geothermal Energy Credits, covering eligibility, application procedures, financial incentives, and ways to maximize savings. Whether you’re a homeowner in Montgomery County or Prince George’s County, this guide will help you navigate the available incentives and take full advantage of Maryland’s renewable energy programs.
Understanding Maryland Geothermal Energy Credits
What Are Geothermal Energy Credits?
Maryland’s Geothermal Energy Credits are financial incentives aimed at homeowners, businesses, and government entities that install geothermal heating and cooling systems. These credits are part of the state’s Renewable Energy Portfolio Standard (RPS), which requires a portion of the state’s energy to come from renewable sources.
By installing a qualifying Ground Source Heat Pump (GSHP) system, residents and businesses can claim state and federal tax credits, helping to reduce the initial investment in geothermal energy.

How Geothermal Energy Works
Geothermal systems use the Earth’s consistent underground temperatures to provide energy-efficient heating and cooling.
Winter: The system extracts heat from the ground and distributes it indoors.
Summer: Heat is removed from the building and transferred back into the earth.
This process significantly reduces energy costs, with many homeowners saving 30% to 70% on heating and cooling expenses.
