It is if you consider the cost of the redundancy required for renewable energy to serve as base load once you cut oil, gass and coal out of the supply.
Nuclear can cover this base load until we develop better storage systems for large scale use.
If we had just built nuclear with the modern architecture developed in the 70's onwards we'd be able to move away from fossile fuel FAAR more easily today, without any mjor disasters from the reactor technology from the 50's.
Many ways away from fossil fuel, both solar and nuclear would have been great options, but even with early solar, we would have had to use coal or gass for base load without nuclear was what u was trying to say.
How we let them was just by not standing up and not holding them accountable. That is still the issue today. They knew for DECADES and still is profiting with government subsidies everywhere. We need to push politicians away from lobbying and give them the support they need to be firm with the 1%.
