"Productive wind is only available in a limited number of states and their regions..."

The best wind resources are located offshore of both coasts, in close proximity to major load centers.

At one time, I know one of the concerns with Georgia offshore wind was that it is in a hurricane prone zone. Insurance companies were not interested in writing coverage on wind turbines in such locations. So if a utility wanted to put up such wind turbines, they would take the risk of damage without insurance.

That situation may have changed. Also, when there is a lack of insurance availability, quite often groups of companies (such as utilities) get together and form their own insurance association for the risk.

Does anyone know what the situation is now?

Or the gov comes in and insures the whole industry, as they have for nukes for decades.

Having the government insure the offshore turbines would be better than private enterprise insurance anyway, given the current status of insurance companies generally and AIG in particular.

I do have a question that someone may be able to answer: would not offshore wave energy production be better than offshore wind energy? Why are we assuming that wind energy is going to be the main component of offshore energy production?

Because industrial experience with wave energy is still insufficient to take it for viable and competitive with wind energy.

In general, wind and wave energy density are correlated; the best sites for one are near the best sites for the other. If both modes are co-located, transmission infrastructure and maintenance effort can be shared.

A company called Wind Energy Systems Technology is developing a wind farm off Galveston, TX. Their meteorological research tower survived a direct hit by Ike last year.
