So wind turbines not only kill birds, but they also cause light pollution.

They still managed to slip in hydrogen. Not against it and likely has some important future roles, but as the issue has been discussed in other threads, not appropriate for commuter transportation for the foreseeable future and most of this appears to be driven by lobbyists instead of science. Will remain cheaper and more effective to use grid batteries for the near future to buffer wind growth.Good article about the off shore win coming to the US.

- Governments, energy companies, and end users are increasingly looking at offshore wind as a power source to produce green hydrogen, which can be used in other sectors of the economy — like transportation, heating, industry, grid storage — as a zero-emission fuel.
The Biden administration announced on Wednesday a plan to develop large-scale wind farms along nearly the entire coastline of the United States, the first long-term strategy from the government to produce electricity from offshore turbines.
…Interior Secretary Deb Haaland said that her agency will begin to identify, demarcate and eventually lease federal waters in the Gulf of Mexico, Gulf of Maine, New York Bight and off the coasts of the Mid-Atlantic States, North Carolina and South Carolina, California and Oregon, to wind power developers by 2025.
Biden Administration Plans Wind Farms Along Nearly the Entire U.S. Coastline (Published 2021)
Interior Secretary Deb Haaland announced that her agency will formally begin the process of identifying federal waters to lease to wind developers by 2025.
Next year, Danish wind turbine manufacturer Vestas will put up a gargantuan prototype - a 15-megawatt (MW) wind turbine that will be powerful enough to provide electricity to roughly 13,000 British homes.
It will be the biggest such turbine in the world, though potentially not for long. Wind turbines just keep getting bigger - and it's happening faster than almost anybody predicted...
..."We've worked out that a single turn of a 14MW turbine would power a Tesla Model 3 for 352km (218 miles),"
Why giant turbines are pushing the limits of possibility

Given the recent experience with the major HVDC to France going down, as well as currently being shafted on natural gas import prices, I think that adding a large, long connector to North Africa is probably not going to generate a lot of enthusiasm in the UK.
3-D Printing Sky-High Wind Turbine Towers with Additive Manufacturing (Video)
Ok, this is seriously cool, but got me thinking that there might be a composite material that could be 3-D printed ALL the way to the top of the tower. Material should be lighter than concrete, something more like fiberglass, probably better to have carbon fibers. I’m not a structural engineer, so no idea on the forces and structural strength needed, but should be possible with a honeycomb interior structure. Imagine also printing a screw thread inside, and thus the robotic print head could “climb” inside while printing, then climb down when done. This would eliminate the need to have the massive crane during that phase of construction. Finally, mass produce print heads and build 100s of towers simultaneously. New business for Tesla?

Composites which need strength in more than one direction are typically woven, I'm not sure how that could be integrated into printing.
