Our Sun is the nearest star to our planet Earth. Just a tiny fraction of the Sun's energy that hits the Earth (around a hundredth of a millionth of a percent) is enough to meet all our power needs many times over. In fact, every minute, enough energy arrives at the Earth to meet our demands for a whole year - if only we could harness it properly. Without the Sun, life would not have existed on our planet. We use the sun's energy every day in many different ways. When we hang laundry outside to dry in the sun, we are using the sun's heat to do work -- drying our clothes. However, instead of using the renewable & natural sources of energy, such as solar, wind, water…etc, we are incredibly using the fusel fuels although the greenhouse gases problem is increasing with its terrible effect on the only planet that we can live on so far “the Earth".
