Well said, theo, on the subject of tidal power. To me, it is the way forward, far superior to wind power for the reasons you mention. I'd add in hydro-electric power in as many sites as possible - not only a source of energy thanks to gravity, but also a reservoir of fresh water, potentially needed for hydrogen production. Plus if we can take energy from underground to run heat pumps for homes, surely there is a potential for extracting heat on an industrial scale.

It's all too complicated for my brain to make sense of, but surely every avenue should be investigated now, not just talked about.
