1) Does wind power actually work?
Not only are industrial applications of wind power centuries old, wind is the single fastest growing sector of the modern energy economy.
2) Is there really a demand for wind power by utility customers?
The popular demand for wind power is far beyond our ability to supply it. As of September 2005, 176 cities back this up, and more are on the way. See http://www.iclei.org for the latest count of cities supporting and demanding wind power.
3) If the wind doesn't blow all the time, doesn't that make wind power unreliable?
The power grids of the U.S. can and do accomodate wind power quite effectively into the mix of power generation sources. With every megawatt produced from wind, the grid also conserves water for agriculture, wildlife and future hydropower, and saves water otherwise consumed through the processing and burning of coal.
4) Why is building more wind power important?
Despite having been a politcal football for decades, as of 2005 even the White House acknowledges that climate change is real. Climate change is directly impacted by our production of green house gasses- which are a non-issue with clean, eternally renewable wind power.
5) Isn't wind power too expensive?
New utility-scale wind power facilities already cost less per kilowatt/hour produced than new coal plants, and the cost is continues to drop as the technology improves. A single existing coal plant, on the other hand, can cost upwards of $600 million just to be brought into pollution standards compliance. If the very real economic cost of the damage coal does to water, vegetation air and human health were included in any comparison, wind's cost-effectiveness would increase by an order of magnitude.
