Wind power is excellent for certain things. Pumping well water into tanks is one of them, and no subsidies are needed. Generating electricity for attachment to the grid is far less beneficial--and far less certain. The wind is extremely flukey, although it may be not be apparent to someone who has never watched a wind generator in action. Horizontal axis generators spend a lot of time 'hunting.' Vertical generators wouldn't seem to have that problem, but there may be other issues with them that I am unaware of.
As visual polluters, wind farms are monstrous eyesores. Altamont pass is a good example.
I don't see the tax credits that are coming out of our pockets going into basic research that can develop new technology, but into subsidizing the construction of something that isn't cost effective. I would rather the money be spent on something that has enormous potential, such as fusion research, rather than wasting it on something with clearly limited value.
The current fad to subsidize anything supposedly 'green' reminds me of the investment tax credits of years gone by. Much of that money was wasted on people investing in business activities that had no sound economic basis, some of which weren't even in the US. We subsidized every thing from charter yachts in the Caribbean to Donny Osmond record masters, and yes, I know people who did both and received tax credits for doing so.
My own wind generator is packed away, along with the solar panel, waiting for the day I need a little more power than TVA can supply. /forums/images/graemlins/wink.gif
