eldavojohn wonders: "In the October IEEE Spectrum magazine, I read an article on backyard windmills and their growing feasibility. With the lowest model's price tag, it's about $9,000 and lasts for around 100,000 kilowatt-hours (20 year life), which results in 9 cents per kilowatt-hour. Now, the article mentions that if the market takes off, that price will drop. However, I was wondering what price range the windmills would have to fall to (or the energy rates have to rise to) before I could consider this? Well, the price of the windmills in the article are out of my price range right now. I don't imagine many Americans have $8k-$11k laying around and the current month's rates for energy in my neighborhood are 2.2 cents/kWh for the first 800 kWh and 1.2 cents/kWh after. I was wondering what are your thoughts on being an early adopter of wind energy? Do you think that if enough people bought these windmills, the price per kWh could compete with the local power grid's? Will it ever?"
