You can certainly have the discussion, but it would not have helped. We are still having discussion TODAY and it's doing nothing of any consequence.
The only thing that matters for actual deployment is how much the energy source costs. Nuclear power costs were dramatically increased due to unnecessary fear.
For example solar power needs inverters - but those didn't work well back then. It just so happens to right now technology has finally reached the point that alternate power actually is cheap enough to deploy.
So we are deploying it.
All the "climate talk" is doing nothing, what actually matters is the money.
