In the EU, there's testing facilities that are checking these at this 20 MW size now. Commercially at this point there's up to 17 MW operating in the North Sea.
I'm pretty pessimistic about climate change. But the way wind and solar just keep getting cheaper and better gives me a certain amount of hope.
Wind energy is also getting constantly cheaper, both due to cost reductions and due to making the wind generators larger and thus more efficient. Onshore wind energy is the cheapest in Middle Europe and if they could grow further, costs would go down accordingly.
But even if production can deliver, getting the blades gets more and more difficult, so here we area.
At 150m above ground where there rotor hub sits wind blows all the time.
