Green, Eco Friendly Class A Monoblocks

Every time the power goes out where I live, I am reminded how much my life and interests revolve around electricity.

So as I contemplate a new house, with a dedicated circuit for audio equipment, I am wondering if there is yet any sustainable, green, or eco friendly technology which could supplement or perhaps even meet the demands of the hungriest audio and video systems.

Could anyone please comment on the latest solar or alternative energy sources which could meet the demands of a traditional high end audio system?

(Not as excited about switching to class D amps and/or renewable iPods.)

Thanks and hope this is of interest to others.
