The Maine Heating Cost Problem
Maine's extreme oil dependency creates the strongest economic case for geothermal in all of New England. A typical Maine home burns 800–1,000 gallons of oil per year at $4+/gallon, spending $3,200–$4,000 annually on heat alone. Geothermal reduces that to $800–$1,200 in electricity. Efficiency Maine provides rebates up to 1/3 of project cost, and the combination of high fuel costs and long heating seasons accelerates payback dramatically.

Maine Geology & Drilling Conditions
Maine's geology is dominated by ancient metamorphic and igneous rock — granite, gneiss, and schist — providing excellent hard-rock conditions for standing column wells throughout most of the state. Coastal areas may have glacial till and marine clay overburden requiring careful site assessment. Northern Maine's remote terrain can present access challenges, but the underlying bedrock remains highly favorable for geothermal drilling.
Communities We Serve in Maine
💡 Maine burns more heating oil per capita than any other state. The economic case for geothermal conversion is stronger here than anywhere else in New England.
