Renewables in Power
Renewables ~ 7-8% of Capacity and 3% of
generation at present
High growth rates – Wind, PV, moderate
growth – small hydro, bagasse cogen
Integrated Energy Policy, MNRE – estimate
only about 6 % of share in power generation
Climate Change – GHG mitigation- major
driver
Need to explore Concentrated Solar Power
