Solar power energy. Photovoltaic cells convert light into an electric current using the photovoltaic effect. Solar energy is the technology used to harness the sun s energy and make it useable. Solar technologies can harness this energy for a variety of uses including generating electricity providing light or a comfortable interior environment and. Solar energy is the cleanest and most abundant renewable energy source available and the u s.
Solar energy radiation from the sun capable of producing heat causing chemical reactions or generating electricity. Has some of the richest solar resources in the world. As of 2011 the technology produced less than one tenth of one percent of global energy demand. Solar industry is helping to pave the way to a cleaner more sustainable energy future.
Solar power is the conversion of energy from sunlight into electricity either directly using photovoltaics pv indirectly using concentrated solar power or a combination concentrated solar power systems use lenses or mirrors and solar tracking systems to focus a large area of sunlight into a small beam. It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. Through a portfolio of r d efforts the energy department remains committed to leveraging america. The total amount of solar energy incident on earth is vastly in excess of the world s energy requirements and could satisfy all future energy needs if suitably harnessed.
