I don't know what the differences are, but over in Denmark, I saw many homes and farm houses with solar panels and even a few with smaller wind generators. I do know for a fact that the wind energy works. My cousin over there is CEO of EnergiDanmark and he said that his company had a 2.6 billion dollar turnover 2 years ago. I also read that this month, Denmark's wind generators produced 140% of the entire nation's electrical needs. No wonder my cousin bought a fancy speedboat and a new range rover. He's got the big bucks!
With a combination of solar panels and wind energy providing electricity for your home, I would think it would pay for itself eventually. And it's pretty darned cool that it works so well. I'm also eager to see how improvements are made in the coming years. Oil and coal are finite resources, so it is good that strides are being made in renewable energy.
