Sun, since time immemorial, has been the only source of energy in our part of the universe. Energy from the Sun, for billions and billions of years, has been received by the Earth. This energy coming to the Earth in the form of rays is known as solar radiations.
Radiations from the Sun can be transformed into other forms of energy like into heat energy, electrical energy, etc. The British astronomer John Herschel, in the year 1830, was in an expedition through Africa. During his voyage he employed a device that used to collect heat of the absorbed light from the Sun with the help of a device called solar thermal collector box. In the present world it is used for varied purposes in different fields of life.
Conversion of energy from the Sun to other forms of energy is possible. Chiefly, it is transformed to thermal energy and electrical energy, and utilized in many applications. Thermal energy, also known as heat energy, from the Sun is employed as water heating as is used at home for domestic purposes, in buildings and in hot water swimming pools. Also it is used as heat spaces, typically, used in greenhouses, for domestic purposes, and in other buildings. Moreover, if converted to electrical energy, it has two major applications. Firstly as solar cell, also known as photovoltaic cell, in which electrical energy is formed directly from solar radiations. There are often installed in the localities where there electric power stations are far away. Apart from it, it is widely used in watches, calculator, and street lights.
Electrical power plants, energized from the Sun, work on the fluid medium which on conversion into steam runs an electric generator. In the United States, at the end of the year 2006, there were 15 such solar power stations were in operation. Out of which, 10 were installed in California alone and the remaining were in Arizona. There are other solar stations also, operational in many other parts of the United States, which produced less than 1 megawatt of electrical power.
