Alternative Energy in India saw significant growth in 2010 with the last 9 months of the year seeing capacity additions of 1800 MW which is almost 10% of the total installed capacity of 18500 MW.The growth in renewable energy was led by Wind Energy which forms almost 70% of the total renewable energy capacity in the country at around 13500 MW.The strong incentives given by both state and central government has led to the sharp growth of wind energy.Note Wind Energy is quite close to Gas based electricity price.India Needs at least 68 GW of Renewable Energy Capacity by 2020 to meet its RPS target of 15% set by CERC (note this is capacity only not hours of electricity).
