Not just with uranium-based nuclear fission power, which is what's on the table. That's a short term temporary solution at considerable expense. Uranium is rare. If they get a thorium-based fission power station working, that would be a different story. Thorium is relatively plentiful. Or economically viable fusion, of course, but nobody's talking about that happening soon.
Kite-based high altitude wind power would be useful. Wave power likewise. Both are reliable and common around the UK.
A mix of methods would be a good idea, as there are drawbacks with all of them.
