I joined two projects:-
Actually, I started with SETI@home alone at first, but after so many number crunching, it's hard to find any result. Of course, it's expected, but anyway, to use resources in a better way, I joined Einstein@home which should be more promising.
No matter how, I hope this little effort can help a bit in those research afterall.
However, the bottom line is that, I believe these projects are sucking a lot of electricity and "contributed" quite a part in the pollution problem. So, let's just keep it at certain level only.
