I've been hoping that by the time I need a new roof on my house, solar shingles will have come down in price. I purposefully planted my trees away from the house so they would shade the sides of the house but wouldn't block the roof top. And the trees drop their leaves to let sun through in the winter at lower incidence angles.
The added benefit is when a tornado came by and blew a tree down in our backyard, it missed the house.

Since I design, build, optimize and run power plants, having a personal power plant would be sweet. At least one bigger than the miniatures I build with the kids. I be futzing around with my plant all the time, tracking it on the computer. I'd Get some t-shirts, hard hats, and stuff made and make myself the plant manager.
