"Renewable systems are the only energy generating systems which have the combined benefits of renewability, decentralization and availability on demand without need for separate storage", Alagusundaram said.
At present total renewable energy based power generation in India was 28,000 MW out of total generation of 2,30,000 MW, which worked out to be 12.17 per cent only, he said inaugurating the 21-day "Winter School for renewable energy as option for mitigating climate change", at Tamil Nadu Agricultural University.
India's energy consumption has been increasing at one of the fastest rates in the world due to population growth and economic development. Commercial primary energy consumption has grown by about 700 per cent in the last four decades, he said.
The per capita consumption was to the order of 1,000 kWh per annum and driven by the rising population, expanding economy and a quest for improved quality of life, energy usage in India was expected to grow at a exponential rate,he said, adding, increase in population, accompanied by rapid urbanization and industrialization led to increased use of fossil fuels.
