Fact: Germany has 18,400 MW of windpower and is finding it very hard to expand onshore. They've got two problems;

i) the subsidy is too high - raising the overall cost of wind to the end consumer
ii) it is not a windy country - load factors are in the teens - most investors wouldn't touch anything below 25%
iii) offshore is still in its infancy and much more expensive

So where to go next?

The answer it seems is Poland.

Interested companies that are listed AEI stocks include the Spanish stock Gamesa.

Europe's wind boom is changing location from West to East. Other than Poland, I also think that there's plenty of scope for going somewhere like Albania or Ukraine, where planning permission I suspect would be a lot less hard to come by.
