Solar, wind turbine, and electric car

So we already have the solar system built in and the sunshine taken care of. Since our electrical needs are already very low, I'm expecting some excess power generation, and it saddens me to think this is going to go to Yonden, the local power company for a pittance.

Now our car is getting old, and petrol is not getting any cheaper. And both Subaru and Mitsubishi are talking about producing electric passenger cars in 3 years or so.

It occurs to me that getting an electric vehicle at some point would be a good way of soaking up the excess juice, assuming there is any. And if there weren't enough, the area where our house is to be is known as a windy area.

So the questions are, is the wind strong enough to merit a wind turbine, and which one to get?
