This is a fantastic tool that lets you plug in your location and then will tell you the wind and solar potential in that area. It will also tell you if there are any incentives for wind or solar in your area and give you some vague costing on a starter project.
Unfortunately, it tells me that wind and solar are both not great alternatives for my area. Still, I'm thinking of continuing down the solar avenue, at least for hot water heating. What does it say for your area?
