I doubt so as most of the challenges I mentioned aren't due to any subjective appreciation. China invests way, way more on renewable than on nuclear.

Indeed! Experts (International Energy Agency, McKinsey, etc.) are clear: renewables will produce the majority of electricity by 2050. https://www.iea.org/commentaries/tripling-renewable-power-ca... https://w

Yes, there are two types of load-following: "bump up the power", or "lower it". This also applies do renewables: not producing (many wind turbines are equipped with a braking system) or wasting an excess of power isn&#x2

Nuclear can be apparently cheap (its TCO is difficult to establish because gov funding, hot waste potentially breaking havoc in a distant future...) but never is when load-following, because load-following reduces the load factor, and a low

Proponents of the SMR (small modular reactor) overlook the fundamental approach in industry: taking advantage of economies of scale to improve efficiency. Financially, SMRs are efficient when they are mass-produced and then installed as is,

It is about more than "being alive and well" but being omnipresent and determinant. Stating it is useful because many neglect (or maybe even ignore) this fact. The way the War Nerd puts it is IMHO the best.
