However, wind power is NOT all that cheap (it's amazing how much I picked up about wind generators from living less than a mile from the Clipper Windpower factory and talking to employees and ex-employees).
It's JUST starting to get competative with coal generation, due mostly to the EPA "war on coal" over the last couple decades, and is close to natural-gas fired plants.
It DOES beat oil, but oil for power generation has been dying for decades in the US due to natural gas stomping it into the ground on cost since the first Arab Oil Embargo.
When I was researching power prices I found some areas in Texas that had so much wind power they practically had to give it away (3-4 cent on average). This was about 18 months ago. I guess it depends where you are looking and how close you are to a giant wind farm.
Texas colo data centers are annoying. I've used in the past and if you don't mind paying property tax on gear you send there. Too much paperwork and complication.
