SOLAR ENERGY-long term source
Energy is inevitable for the existence of the universe. This world's main source is sun. The major problem experienced in all the country is the non-avilability of synthetic and fossil fuels. The solar energy enriches a lot of nutricians.
There is no pollution in this system. To avoid the pollution and at the same time saving firewood, we have to use solar energy. Sunlight is the source for solar energy.
Sunlight is one of the nature things which is used mostly in various fields. This face is that all energy on earth originally, comes from the sun.
The generally used hydrocarbon, fuels such as cool oil and natural gas are originally produced by the action of sunlight on vegetation.
The solar energy having the high heat energy. It has substantial and dependable potentiality. It has the sources of renewal energy. It is used in India. It can be utilized for multipurpose. There are various applications of solar energy in now a days.
Generation of electricity is an outcome of solar energy. Photovoltaic solar cells change the solar energy into electricity. Following figure shows the Photovoltaic solar cells.
The following shows the functional diagram of photovoltaic solar cells.
The energy which we obtain from the sun is used to energize pump sets of irrigation, to supply drinking water and to run rural electrification. Lights, television sets, medical refrigerators are operated by using solar energy.
Apart from the generation of electricity, solar energy can be use for cooling of residential building, heating water, drying agricultural and animal products, using solar distillation, salt production, solar cooling, solar cooling, solar furnaces and food refrigeration and driving the vehicle.
Petrol and petroleum products in the world may suffice only for the short period of time. Hydro electric power is also not enough to meet the growing needs of this modern age. Nuclear reactors and radioactive materials are suitable as threat the mankind. Because they give side effects to living things.
In effect, solar power is said to be reliable and economically viable source of energy.
Indians may use it in large number. Because it is an application free from pollution. A nation's development depends upon the solar energy. Solar energy is a gift of Nature for us.
Solar energy yields the greatest potential of the renewable energies.
It gives 1000 times more energy that what we need. With the help of hydrogen or mechanical or electrical devices, solar energy can be stored. The potential for wind energy is immense source of power. The technology available for exploitation is costly. Despite it is must for the growing population's consumption. Solar energy gives hope to future.
