It is a fact very well-known to everyone that all living things depend greatly upon solar energy to survive. From the tiny microbes to human beings, everyone needs solar power for their survival. Solar energy combines the heat and light in electromagnetic radiation form. Solar energy is absolutely environment-friendly as in it does not emit any amount of carbon or other harmful byproducts. This type of easily available source of energy can be used for the benefit of the planet in a cost effective way and can be used in any part of the planet. Many countries have already started using solar energy for different purposes. For example, the United States of America have introduced the solar water heating system which is being widely used all over the nation.

The cheapest and most convenient use of solar energy can be seen in the room heating techniques. It is widely applied specially in the cold climate countries where it helps to keep the inside of the room warm. In fact a wide are like the swimming pools are also kept warm using this method. The technological advancement has led to a broader platform for using solar energy as a cost effective alternative for the conventional electricity. The latest invention of solar powered airplane by NASA has opened a whole new opportunity for mankind. Solar energy is now being used to run vehicles which is a remarkable discovery.

Apart from this there are many other applications of solar energy in our daily lives. The solar flashlights, solar radios, solar battery chargers, solar calculators, solar fans, solar hybrid chargers, solar backpacks etc are example of this kind of alternative energy.
