100% solar is a strawman you constructed. Nobody is suggesting anything close to that. And don't pretend that uranium mining is a clean business.
Power to gas technology is still in its infancy, efficiency rates will improve as it is scaled up. Every technology starts out small.
Any nuclear project we start now won't be producing power for at least a decade, more likely two. We don't have that time. You might have had an argument twenty years ago, but arguing that we can defer renewable investment if we just build enough nuclear now doesn't make sense to me. By the time your proposed plants start to come online, the transition needs to be complete.
And if you're truly interested in debate, maybe you shouldn't compare your opponents to a murderous regime?
