Geothermal heat pumps capture the solar energy stored in the Earth's subsurface to provide heating, cooling, and hot water for homes and commercial buildings in a renewable and efficient manner. By taking advantage of the Earth's natural temperature regulation abilities, geothermal heat pumps can reduce energy consumption and costs by up to 60% compared to conventional HVAC systems while also lowering carbon emissions. Incentive programs in many states and proposed federal tax credits aim to further promote the adoption of geothermal heat pump technology as a sustainable and cost-effective solution for heating and cooling needs.
