Prakash and Ghosh in the Hindusthan Times remind readers that even though India has ambitious plans for renewable energy much remains to be done in shifting to clean coal technologies. An estimated 80% of India's coal plants use obsolete technologies, making this an obvious area for improvement. India plans to make solar the source of 100GW of 175GW it plans to generate in renewable energy by 2022. Yet it must not be forgotten that coal is a dominant source for the foreseeable future and shifting to clean coal technologies is an area that should get top priority from the government. Today India is the third largest in terms of carbon emissions after the U.S and China.
