Hi friends, according to law of thermodynamics, energy can neither be created nor destroyed and it can only change forms. We are living in an era where demand for energy is increasing with increase in human population. To meet this ever increasing demand, fossil fuel resource hidden beneath the Earth is being exploited and it may not last longer. Now it is time to look at “Pancha Bhoota” or 5 elements for fulfilling our need of energy. Our universe including our body is made of these five elements - earth, water, wind, fire and space. All these elements are rich source of energies and more over they are renewable. For example, heat energy from Sun will be always there and nobody knows how many billion years it may take before Sun stops emitting heat and light to us. So we already on the process of taping light energy from Sun and using it for heating purpose. Similarly wind energy is converted in to electrical energy using large windmills and as per theoretical calculation the entire global electrical power demand can be met by wind energy. Since the initial cost of setting up a windmill is very huge, it is yet to become common man’s choice. In India, private players are investing in this filled looking at the potential for making profit in the future. If we set up more windmills wherever there is scope for rotation of windmill wheels, it will result in reduction of global carbon foot print.
