Geothermal Technologies Program

The U.S. Department of Energy's Geothermal Technologies Program works in partnership with U.S. industry to establish geothermal energy as an economically competitive contributor to the U.S. energy supply.

Solar Energy Technologies Program

The Solar Energy Technologies Program focuses on accelerating market competitiveness by targeting cost reductions and supporting increased solar deployment. Subprograms focus on photovoltaics, concentrating solar power, systems integration, and market transformation.

Solar Power Purchase Agreements

A Solar Power Purchase Agreement (SPPA) is a financial arrangement in which a third-party developer owns, operates, and maintains a photovoltaic (PV) system, and a customer hosts the system on its property and purchases the system's electric output for a predetermined period. EPA's Green Power Partnership provides information on SPPAs, how they are structured, and the benefits and challenges of implementing them.
