Solar energy is the most readily available source of energy. It does not belong to anybody and is, therefore, free. It is also the most important of the non-conventional sources of energy because it is non-polluting and, therefore, helps in lessening the greenhouse effect.
Solar energy has been used since prehistoric times, but in a most primitive manner. Before 1970, some research and development was carried out in a few countries to exploit solar energy more efficiently, but most of this work remained mainly academic. After the dramatic rise in oil prices in the 1970s, several countries began to formulate extensive research and development programmes to exploit solar energy.
When we hang out our clothes to dry in the sun, we use the energy of the sun. In the same way, solar panels absorb the energy of the sun to provide heat for cooking and for heating water. Such systems are available in the market and are being used in homes and factories.
In the next few years it is expected that millions of households in the world will be using solar energy as the trends in USA and Japan show. India is one of the few countries with long days and plenty of sunshine, especially in the Thar desert region. This zone, having abundant solar energy available, is suitable for harnessing solar energy for a number of applications. In areas with similar intensity of solar radiation, solar energy could be easily harnessed. Solar thermal energy is being used in India for heating water for

I am in Solar Energy Business. Mind you it is very very costly. It has not yet developed to the stage that millions of households in India can use. In Japan, USA, Germany, France, Italy the governments are supporting it with a subsidies in the range of Rs.30 - 40 per Kilo watt Hour (Unit) of generated power on every house for 20 years. Solar energy will take centre stage when the technology improves. The present technology is at a stage WHAT COMPUTERS WERE IN 60s. A long way to go.

I really don't know if you people have seriously knows about the energy crisis that that the country is going through or will go through. Just imagine a city like kanpur and lucknow has 8 hours of power cut , its neighbouring cities and village does not have electricity at all. i was in kanpur for two days and it was hell over there. Forget about the cost, we spend so much of money everywhere, lets spend something extra for the benefit of poor.
