I would like to know whether any work known to bitcoin community, related to 'green mining'. As power consumption is main cost factor in mining, alternate energy sources like, solar / wind powered rigs could also be possible. Thanks.

One attempt, .... Diablo Mining Company didn't go so well.
So far, the most profitable mining has been in nations whose taxpayers provide subsidized electricity. Essentially, it is like a form of welfare for Bitcoin mining entrepreneurs.
ASICs have removed that advantage though so it never got to be that big of a deal.
