Sun is a vital boon for humans on this earth. So humans should make full use of it. Solar energy does not require a meter and does not have to pay electricity bills. Degradation of trees is stopped and pollution free environment is created. Uninterrupted power supply is available for agriculture. Wind energy is the energy obtained from the wind. We can convert this energy into electrical energy through a generator. Which helps to replace energy produced by fossil fuels. Wind energy is obtained by converting the movement of wind turbine blades into electrical energy. Wind is free, easily and abundantly available. So humans need to augment these natural uses. If this is done by a human being, it will be like a gift to the world like nectar and will be the most important discovery in his life.
