How Solar Energy Works

Solar energy is the energy from the sun to which we are endowed with. It is the power which is free and inexhaustible. It is the cleanest of all energies, for it is produced by the sun.
But, have you given a thought and asked a question about how it works. For al those who have not done that and therefore, are unaware of it, this short article maimed a helping hand to you.
It is an energy resource that serves as an alternative option to fossil fuels which are not so good for our water and air. As you know, they are a threat to human life. Besides, this leads to one of the factors that causes global warming. Our children and future generations will be affected if we do not make use of this resource. And, when it is widely available, then, not using it means great injustice to the future generation. All the life on earth is supported by the solar energy and it is the underlying root for almost all the energies we use.

The plants grow with the help of sun which make its way to get burnt in the form of biomass fuel. Else, they are compressed underground for millions of years or they are left to rot in swamps. Temperature differences happen due to the heat generated by the sun.. Wind is produced due to the sun which power turbines.
Due to the sun, water gets evaporated and falls on high elevations. Then, rushing down to the sea, it spins hydroelectric turbines as it passes.
But, mostly solar energy represents the manner in which energy of the sun can be made use to directly produce heat, lighting and electricity.
However, the sun generates radiant energy by consuming hydrogen in nuclear fission reactions. Then, this energy is transferred to the earth in chunks of energy named as photons. They react with the earth’s atmosphere and surface.

It takes 8 minutes and 20 seconds for the energy of the sun to reach out to the earth. Solar energy is received and collected by the earth in the atmosphere, oceans and plant life.
The reaction between the sun energy, the oceans, and the atmosphere, for instance generates winds that can endow electricity when directed through aerodynamically designed wind machines.
