> Old wind turbines might be perfectly fine but they are also no longer competitive with modern replacements. Usually it does make sense to replace them with more modern alternatives.

I would just for once love to see a calculation for this. There have been no advancements in generator technology nor in blade technology. Generators in power stations have a life time of many decades. A third of the 31000 German wind turbines will be put down because of the end of subsidies.

Also subsidising solar power in the north of Germany makes no sense - for months there is no solar in winter but in summer solar adds to the already massive surplus of energy from offshore wind. It is a waste of money. If you believe that global warming is a problem (which I agree with) then the money should be put to efficient use.
