Solar Power is the only future

Necessity is the mother of invention. Look at the reality. Per capita energy consumption in India is 800 units/annum. For a quality life, it has to be 4000 units/annum. Indian government's 12th five year plan target is to raise it to 1400 units/annum. By 2030, we will be reaching 2500 units/annum. We need lot of energy. The coal available in India will exhaust in another 75 yrs. We do not have oil or gas. We have to depend only on Nuclear and Solar. Micro grid concept has to take place. Otherwise, India will perish. India's average age is 26. Young population want to have a decent live. Hence, solar is the only future.

Maybe another perspective:
1. We should look at the available Roof Top Space from residential building versus commercial buildings and factory sheds and also the power consumption pattern i.e. day time or evenings.
2. The average available Roof Top Space from commercial building and factory shed would be at least 5 to 10 times one available from residential premises and therefore we have more power available for feeding back to the grid. The distribution networks for commercial and factory areas are more reliable. We should be in a position to accept the power from such roof-top solar plants.
3. The average space available from residential building (approx 200 Sq m) and effective solar power available from that is small just enough to support that residential load itself . Residence premises would consume less power during day time and therefore it makes sense to have off-grid solar system.
