All life on our planet, be it human, animal or plant owes its very existence to the solar energy. The food chain, the carbon cycle and the hydrology or water cycle are all there because earth is lucky to have sun shining over its surface. The enormity of sun as a source of energy can be gauged by the fact that “In 14 and a half seconds, the sun provides as much energy to Earth as humanity uses in a day.” and over and above that this energy has been falling over earth's surface ever since earth came into existence and will continue to fall till eternity. Additionally solar energy is the mother of other energy sources like wind, tidal and even hydro. Compared to this all much talked about other 20th century energy sources like coal, petroleum, natural gas and nuclear fuel have started their journey towards depletion.
In the light of all this the very idea of harnessing solar energy for energy security on this globe should be the most outstanding idea that ever came to humanity. In fact this could easily qualify to be invention of the human civilization, far too bigger and revolutionizing than the invention of wheel.
In a factual scenario as mind boggling as the one seen above, it is not difficult to understand Why thrust towards renewable energy sources is languishing. It is only the hidden agendas and motivated vested interests of political leaders, industrial cartels/mafias, scientific and technical power groups which will keep on delaying the inevitable as long as possible.
