I'd love to, but our house is crap. Its a duplex, so I can't even put the solar panels up on the roof.
Likewise, we are on a 50x100' lot so I don't have much room. I'd have to hack down a couple trees to get access to the sky. Of course, the house is at the bottom of a hill, sort of in a little valley, so I doubt I'd get much wind unless I put in a huge wind turbine.
I need to move to Montana or something to get better sky access(for solar and wind).
