I have a question, more like a series of questions.
1. How much does a Windmill that would power cities cost on average (I've seen anywhere form $5000 to $50000)
2. If the US went all wind, how much power could be potentially collected?
3. How large is this windmill that which I have already asked about.
This is for my midterm and the Internet is not very helpful.
I appreciate any and all help beforehand!

You can do the research yourself, but i'll give you some guidance. All of the answers are on the web, but you'll have to synthesize them by collecting information from several places.

1a. How much electricity does a typical city consume on a daily basis? (watts per person)
1b. How much power does an industrial-class wind turbine generate?
1c. How much does that wind turbine cost?

2a. It's a big number, but it would be difficult to calculate because of the number of variables.
2b. The real answer is this: more than enough. (After all, we only need 'enough'.)

3. Depends upon answers to 1b, 1c

Suggestion: Call the Sales Department of any wind power company. Tell them you're a student, and you'll be surprised how helpful they are. Don't waste their time: have your questions written out and ready to go, and be fully engaged in the conversation so you can ask followups right way. Don't be afraid to call, and be sure to get the person's contact information so you can call back.
