How much power will the proposed windmills produce and at what cost? Is it significantly cheaper or at least the same price as current sources? Is the power it will generate "significant"?

Wind power now produces energy at lower cost than fossil fuels. Additionally, the supply is forever and, therefore, when the cost of a turbine is amortized, the kilowatt hour cost drops even more. Interestingly, in higher winds (gusts especially) a turbine's output increases exponentially.
The Vestas model located in Hull Massachusetts costs roughly $700K and can provide power to at least 250 homes, the larger ones can go upwards of $2 million. Constructing a new energy plant costs millions just as a windfarm does, however, the conventional plant requires the purchase of whatever fuel it needs to burn. A windfarm never needs fuel. Maintenance costs are lower as there are fewer moving parts, far fewer safety concerns, and a much smaller workforce required.
Some noise does exist (a whoosh, whoosh in the very immediate area) but is a moot point in an offshore configuration.
They provide an elegant and compelling solution to our energy needs as every wind turbine represents less hard currency going abroad.

Wow, someone's asking questions instead of echoing Rush Limbaugh's ignorance.

How refreshing! :-)
