I took a look at the list of wind turbine manufaturers in Wikipedia:
http://en.wikipedia.org/wiki/List_of_wind_turbine_manufacturersAs far as I can tell, at least the following corporations supply both nuclear and wind products:
Areva
Daewoo
Doosan
GE
Hyosung
Hyundai
INVAP
Mitsubishi
Samsung
Siemens
Suzlon
There is a preponderance of crossover in S. Korea (due to their love of heavy industrial conglomerates), but American, Japanese, Argentinian, Indian and French corporations are all doing it.
On the other side of the coin, there is very little product overlap between coal and nuclear companies. The closest they seem to get is that some companies mine both coal and uranium. So direct ownership crossover seems higher in the nuclear/wind pair than in nuclear/coal. there could be a convergence of interest between coal and nuclear electricity providers in such areas as grid design, since they share a centralized generation architecture. Other than that I see a lot of commentary on the net about how Massey and Peabody are rubbing their hands in glee over Japan's little problem.
What sort of coal/nuclear overlap do you actually see in the marketplace? Or is it the centralized generation philosophy of the two sources that causes you to link them so closely, or is there more to the linkage in your opinion?
