They really need to dismantle their old turbines, that's for sure. Re-powering can probably give much more power output but with a fraction of the current numb

They really need to dismantle their old turbines, that's for sure. Re-powering can probably give much more power output but with a fraction of the current number of turbines. I'm not sure how large and modern turbines fare against older and smaller ones, I sadly get a feeling that they're not much better or maybe even worse. I think blade tip speed needs to be high for high efficiency and that sounds like it can be noisy.
