Energy Conservation & Use of Renewable Energy Sources in India

Energy efficiency simply means using less energy to perform the same task, which means eliminating energy wastage. Improving energy efficiency is required to narrow the gap between energy demand and supply. Benefits include reduction in greenhouse gas emissions, reduction in energy imports, and reduction in the usage of available energy for industrial production, commercial activities, urban & rural development, and for household requirements.

The development of any country depends on a great extent on the availability and usage of energy. The vast bulk of the energy used in the world today is in the form of non-renewable oil, natural gas, and coal. These resources were available millions of years ago and are at present being consumed at the rate of 9 billion tonnes of coal equivalent to 0.32 million Penta Joules (PJ) per annum. This compares with the proved recoverable energy resources of 20.3 million PJ of coal and 11.2 PJ of oil and natural gas.
