Britain, (which is where Snorvey was referring too) on the other hand, has huge renewable resources relative to all European demand. It has huge amounts of seabed shallower than 50 metres, and we've already got some offshore wind at those depths; and lots more seabed at 50- 700 metres depth, where we now have the technology to deploy.

Indeed, but to compete with carbon/hydrocarbon based generation, either the market or govts need to double or treble their cost, or costs of windmill generated power needs to drop by around two-thirds to be competitive.
