AEMO boss says nuclear too slow to replace coal, and confirms that “notion of baseload” will not compete with grid powered by cheaper renewables.
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.
There are historical accounts of volcanic activity blocking the sky, I think in Europe, for a few years. For all we know it was the whole planet. That would definitely disrupt solar energy collection without being an extinction level event.
Diversity is a genuine factor of fossil fuel free energy generation.
