Solar energy is the oldest source of energy known to mankind, and is also the origin of other forms of energy used by man.
Other renewable sources of energy such as wind, hydropower, Ocean, biomass and energy are indirect forms of solar energy. Solar energy has many outstanding features that make it an attractive proposal. These features are the distribution of wide dissemination, friendly and virtually inexhaustible supply of medium environment.
Solar energy can also be converted into electricity in solar homes by the use of specially designed photovoltaic cell. They are also known as PV cells or solar cells. They are basically composed of silicon and other elements are added to a more efficient combination. These semiconductor days are used in photovoltaic cells. Photovoltaic cells convert incident solar energy into electrical energy. Mounted on the roofs of solar houses to obtain the highest incidence of solar energy and therefore more output power. This electrical energy is stored in special batteries that can be used for a variety of purposes. It can be used to heat, as well as work of cooling devices such as fans and air conditioners. Thus, during the summers when refrigeration is essential PV cells play an important role. This electricity can be used for cooling, and lighting. They also give rise to lower consumption of electricity from conventional sources. Thus, solar sees a role in the replacement of traditional sources of energy in all fields of work not only in a home, but in other aspects of life also.
Agriculture and agriculture are other areas where solar energy plays an important role. India has one of the largest in the world of solar energy. The Indian Government has dedicated a Ministry for energy renewable and extensive work continues in this field. Prominent Indian entrepreneurs like Tata and Birla are involved in this project. Although it is still in its incipient stage these programs have the potential to become a success of ROAR as this will save lots of money for consumers.
The beauty of the solar energy is that it is, the pollution-free easily and freely available in nature and this is a source that will never dry up. In other words the solar energy is called green energy because it has the power to reduce global warming by not cutting trees and forests of wood. Easy to use, no noise or smoke and available in abundance is ideal to change energy in countries where there is sunshine throughout the year.
In addition to agriculture industry is another area where the power is widely used. Construction of power plants causes pollution and generated a large amount of industrial waste from it. Oil and fuel is wasted in these plants. Dykes were built through the rivers so that it generates hydroelectricity. Although this may result in employment, are the nearby towns to be evacuated and their agricultural land is necessary for the construction of dams. Because of this, people start to protest and the projects stop half way. Here the use of solar energy will be ideal since there is no inconvenience to nature, as well as people. Food is available in abundance and people can get on with their lives without being disturbed. All this goes to show that solar energy is green energy as green is associated with growth and abundance.
