We don't talk about it, because we want to get _away_ from igniting huge amounts of underground carbon-based material and putting it straight in the atmosphere. We want to move to methods of power generation that do _not_ significantly upset the delicate balance of a livable planet.
Continuing adding more carbon to the atmosphere is only worsening the situation.
There are so many people that only think in extremes - we should go all in on nuclear and there's no other way. They are the ones that ignore limitations that parent mentioned. Their fantasy will not work and strong opposition to renewables is detrimental to our future.
I don't think anybody except lobbyists argue for that. In most projections i saw from pro-nuclear anti-carbon think tank (such as the one i was memebr of during Covid), the nuclear part in the energy mix vary from 30 to 50% (Depending on what the nuclear would be present for: i think in the 50% model, 60% of nuclear should be controllable plants, vs 100% for the 30% model).
