Energy is important to life, and the amount of energy consumed per capita by a country is indicative of the level of development of that nation. There exist different sources of energy with solar energy as the primary source on our planet. The sun’s energy is inexhaustible, unlimited (by geographical boundaries), and non-polluting. Tapping and utilizing this energy efficiently- even with 10 to 20% efficiency- can solve the threat of climate change caused by the global warming, and also contribute towards the easing of the demand for fossil-fuel. In the developing countries a large proportion of the population is poor and not connected to the national electricity grid. This group of people is weighed down with the high cost, high risks and low benefits of the traditional fuels, candles, paraffin, and dry battery cells. Addressing their energy needs, particularly with clean energy from the renewable sources, will not only result in tangible developmental benefits but also social and environmental benefits. In this article we consider only the direct energy from the sun, and its conversion to heat or electrical forms- the energy carriers of choice.
