The Department of Energy has played a major role in solar energy development through previous research and ongoing activities.  As a result of research and development, the "cost of solar energy has been reduced 100-fold over the past two decades." 1

Concentrating Solar Power (CSP) systems use reflective materials that concentrate the sun's heat energy to drive a generator that produces electricity.

[Photovoltaic] (PV) systems use semiconductor materials that convert sunlight directly to electricity.

Solar collectors absorb the sun's energy to provide low- temperature heat used directly for hot water or space heating for residential or commercial buildings.

Parabolic collectors focus sunlight into a fiber optic system to illuminate building interiors with sunlight.
