This thread is a wealth of practical information for this kind of project. I've been looking into ways to minimize costs and maximize profits and renewable energy sounds like a good investment. I've been researching these double-helix vertical-axis wind turbines that claim to be really efficient at low wind-speeds. In combination with solar pannels would make your demand from the grid be reduced to a trickle. I would much rather build the turbines than spend thousands having them comercially installed, but I'm not so confident I have the expertise to do so. I need to spend some time researching.
