This isn't about what occurred then, it's about the time and opportunity cost of inaction that was fostered by rubbishing climate science and hiding the research.
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.
Similarly, the few countries who have massively built out nuclear power (ie, France) did so because of deliberate government policy, not because their free-market economies were chasing the cheapest source of kilowatts.
