AFAIK, it's not just the utopian "green brigade" as you think. The amount of compensation that the govt. gives when forcibly acquiring land for nuclear projects is pathetically low. Many of them may fighting because they think that is the only way to get better compensation.
See e.g., http://articles.timesofindia.indiatimes.com/2011-03-19/india... the units seem to be unreliable, but we're talking around $3000 per family in compensation (938 hectares over 2335 families at Rs400k/hectare and Rs50 per USD). LOL. I'd stall a project if I was going to be uprooted, my livelihood (i.e., traditional fishing grounds destroyed) and I was given a insultingly low $3k as compensation.
Thanks to the 'green' brigade who live in a dreamland where India survives only on Solar and Wind, there are several "public-interest" court petitions stalling construction on one pretext or another. Local politicians were only too happy to buy media attention and make things worse. To get around this, we are forced to import higher and higher quantities of coal and oil. Yes..that is SO much 'greener'.
In fact several coal power plants are not even running due to coal shortage. This year has been especially terrible due to high temperatures and a bad monsoon leading to more power consumption.
It's a complete mess. And I don't have any optimism that things will improve. We will continue stumbling along to the next crisis..that is if this one gets solved.
