Where Does Solar Energy Come From Wikipedia

The state is required to obtain at least 33 of its electricity from renewable resources by 2020 and 50 by 2030 excluding large hydro.

Where does solar energy come from wikipedia.

There is considerable academic and commercial interest. It is an essential source of renewable energy and its technologies are broadly characterized as either passive solar or active solar depending. Usually photovoltaic pv cells contained in solar panels convert the sun s energy directly into electric energy. Renewable resources are replenished either by.

Solar power the production of electricity from solar energy is performed either directly through photovoltaics or indirectly using concentrated solar power csp. Gemasolar in spain was the first to provide 24 hour power. The sun emits em radiation across most of the electromagnetic spectrum although the sun produces gamma rays as a result of the nuclear fusion process internal absorption and thermalization convert these super high energy photons to lower energy photons before they reach the sun s. A renewable energy resource is one that is being or can be replenished as it is used.

A solar vehicle is an electric vehicle powered completely or significantly by direct solar energy. The term solar vehicle usually implies that solar energy is used to power all or part of a vehicle s propulsion. Solar energy is the transformation of heat the energy that comes from the sun it has been used for thousands of years in many different ways by people all over the world. A solar cooker is a device which uses the energy of direct sunlight to heat cook or pasteurize drink and other food materials.

Photovoltaic cells convert light into an electric current using the photovoltaic effect. Human action eg trees cut down for bio fuel are replaced by. Many solar cookers currently in use are relatively inexpensive low tech devices although some are as powerful or as expensive as traditional stoves and advanced large scale solar cookers can cook for hundreds of people. The oldest uses of solar energy is for heating cooking and drying today it is also used to make electricity where other power supplies are not there such as in places far away from where people live and in outer space.

The spectrum of the sun s solar radiation is close to that of a black body with a temperature of about 5 800 k. California leads the nation in electricity generation from non hydroelectric renewable energy sources including geothermal power wind power and solar power california has some of the most aggressive renewable energy goals in the united states.
