Actually move on with Coal for next 20 years. Coal is bound to get cheaper and maybe with excess capacity where you can import.
I on the other hand sincerely hope India does not stupidly decide to stop building coal power plants by 2022. Currently there are lots of thermal plants under construction. The reason is we still have percentage of unelectrified villages in our country, and when the "poor" rise to "middle", his standard of living will rise and it becomes important to provide 24*7 electricity with no low voltage problems. And only Coal will help us achieve it.
Until unless the rich countries follow up on their pledge to provide renewable energy with subsidised costs, we should follow up on coal. If they are alarmed by Global warming then they need to do something instead of asking developing nations to do something.
