Thanks @moderndayhippie - I've had a lot of fun living off-grid. Among other benefits, the wind and solar power had really tuned me into the weather, the path of the sun throughout the seasons, and even the moon cycles - on a clear full-moon night, the solar panels actually pick up enough moonlight to trickle charge the batteries :) Solar's definitely the way to go - turbines also have moving parts so they would wear out much quicker than solar panels.
