The head of the Australian energy market operator AEMO, Daniel Westerman, has rejected nuclear power as a way to replace Australia’s ageing coal-fired power stations, arguing that it is too slow and too expensive. In addition, baseload power sources are not competitive in a grid dominated by wind and solar energy anyway.
I’m not sure I understand what you’re getting at here to be honest. When nuclear was the fastest, cheapest option we should have been deploying that. Now that it’s not, we should still be deploying the fastest cheapest thing. Solar, wind and batteries continue to be on a rapidly declining cost curve, even back in 2010 but it was still too early to roll them out at huge scale. It’s unlikely nuclear will be catching up any time soon barring major breakthroughs like fusion.
I also strongly disagree with your statement that disasters would impact nuclear and renewables equally. One of these things is certainly much harder to clean up and recover than the other if there is significant damage from an environmental disaster.
We should be rolling out the best available technology at the current time and continuing to improve our generation technologies, including nuclear, as we always do. I’m not sure why we would do anything else.
