Wind power is a waste of money at this point in time. Wind is not reliable, because of this you have to have diesel electric generators running 24/7 to provide the power which means you are still burning oil even when the wind turbines are turning. All they can do is sell the added energy from wind to the grid not replace a single generator, if fact you have to build more diesel generators. Where is the logic in that?
Gonna have to disagree here. Currently most major windfarms are only going up in spots that are pretty much guaranteed to be almost constantly wind-swept. And the "backup diesel" generators that you speak of are largely a boogeyman myth. Hydro-Quebec is in the process of building windfarms that will generate over 2,000 MegaWatts of power to come online between 2011 and 2015.

The only places where backup diesel generators need to be located is in the case of an isolated or remote community that only has one source of power. The city that I live in is powered entirely by a hydro-electric plant about 45 miles away. We do have a backup diesel plant, but this sits idle more than 99 % of the year. Every now and then if there is a problem with the transmission lines they fire the diesel up until they fix the problem. For non-isolated communities the beauty of large-scale electrical grids is that there is a large amount of power available to be distributed, it just depends on demand in specific areas. Contrary to your scare-tactic statement, every windfarm built does not have corresponding diesel electric generators.
Yes, for a large wind power project there will tend to be some kind of alternative backup, but it usually works on a 1:n redundancy- this means for so many windfarms you have one backup plant, and it only needs to run once in a blue moon.
Another great application of wind power is for individual homes. I know a fellow here in my community that has cut his home power bill by more than 30-40 %. How? All it took was a couple hundred bucks at the local hardware store and an old treadmill he was looking to throw out.
He built a lightweight windmill from commonly available materials, hooked it up to the motor from the treadmill, which he then connected to some inverters and a battery plant. Every two days (depending) his little windmill charges up his battery plant for approximately 24 hours of electricity. This means a couple days a week he runs off his own battery plant AND if there ever is a failure of commercial AC he doesn't have to sweat it too much.
