The sun's heat and light provide an abundant source of energy that can be harnessed in many ways. You can read more and find a wide range of solar energy information through OSTI's Solar Energy Web page. From educational materials to radiation resource information, OSTI has pulled together one-stop access to Department of Energy solar energy resources, as well as a listing of featured documents on solar energy research. DOE has played a major role in solar energy research and development. As a result of solar R&D, the "cost of solar energy has been reduced 100-fold over the past two decades" (from DOE's Making Solar Energy More Affordable). OSTI's Solar Energy page is part of OSTI's DOE R&D Accomplishments Web site. Technical reports on solar energy are available through OSTI's Information Bridge.
