Those of us who work with planning to address climate change are always conscious of at what point will we hit the limit of what we can do physically. This is especially true for Off-shore wind which is heavily relied on in most nations climate change (GHG mitigation) plans. We are closing on the limit of available low-depth areas to place wind turbines in Europe, and two issues are helping solve this: higher capacity wind turbines and floating foundations, both under development and testing. Even with these we will eventually hit a limit, of how big 'size' can a wind turbine structurally get to. Also considering severe weather like hurricanes in the Eastern and Gulf of USA. Noting that most wind tech is developed and tested in the North Sea or off Portugal which doesn't have Cat 4 and 5 hurricanes. Want to learn more about these challenges, check out this great article by BBC News on the technology challenges we now face with large wind turbine installations. With great inputs from Vestas, Siemens Gamesa, and other experts. https://www.bbc.co.uk/news/business-58704792
