Wind Energy? Feasible?

Well, I've been researching Alternative fuels for the past week and half, thinking of way out of this mess we've put ourselves in. Ethanol and Hydrogen look really attractive to me, mostly because of the Chemistry, but they have so much obsticles in the way that we still years away from really being able to develope it, market it, and mass distribute it. The one thing I do see promising though is Wind Engery.

Wind Energy is Renewable, Enviromentally Safe, and best of all, Almost no marginal cost. Thats right, forget paying 5 dollars a gallon at the pump, instead of 40 dollars to fill your tank half way, Imagine paying 1 dollar for fuel that could last you a whole week. Now realisticly this doesn't seem possible in the next 10, 20, or even 50 years, but you never know what new technology can come out tomorrow.

At about 300 feet above the ground the wind in the atmosphere is actually relatively constant and can keep powering a turbine no matter how much wind is actually blowing on the ground. This alone could even double the efficiency of some turbines and Wind Farms.

I actually have alot more research to do, but just thought I would share some of this.
