Well....It will be interesting to see how many whale beachings there will be.

“Barely visible” if you are blind. Here’s the ugly truth about the proposed wind farm - Money Pit
https://green-oceans.org/green-oceans-one-pager
Offshore Wind farms are deteriorating quickly and after they stop working it is too expensive to get rid of them so they sit there and rot. Siemens Gamesa (wind unit) stock went down 36% on Friday.
https://www.reuters.com/business/energy/siemens-faces-writedown-siemens-energy-stake-after-fridays-sell-off-2023-06-23/
Offshore wind farms don’t even reduce CO2 emissions for 3 reasons, first because the production of the cement and steel used in them emits CO2, offsetting 10 to 15 percent of the CO2 savings; and second because to stabilize the grid in case the wind suddenly stops, which can happen at any time, uitilities need to have “spinning reserve” which is gas or coal fired plants that are already running and ready to be put into use generating power. Keeping these “peaker” plants running when they are not needed, wastes CO2. And third, the most efficient power plant is the combined cycle gas turbine (CCGT) which uses excess heat from the gas turbine generator to run a second steam generator. These are up to 62% efficient, but it takes several hours for these plants to generate the steam for the second cycle in order to produce the additional power. They can’t just be “switched on” and immediately produce electricity, but a “peaker” plant in spinning reserve can immediately produce power.
But “peaker” plants are only 40% efficient, so they use 50 percent more gas to produce the same electricity. A wind system with “peaker” backup uses almost as much natural gas as a combined cycle plant to produce the same amount of power. About 90 percent of the CO2 savings from wind is offset by the inefficiency of the backup and the CO2 emitted to make the turbines. And if the turbines degrade quickly like the Siemens ones are, it is even worse. Might as well take trillions of dollars and flush it.
