Even with that, renewables are cheaper.

One often hears the pearl clutching about land area, but even in Europe the cost of land for renewables would be quite affordable. Building very expensive nuclear power plants to save on relatively cheap land would be penny wise, pound foolish, an optimization of the wrong metric.

The core issue with renewables is reliability. Who cares it's cheap when it doesnt produce energy when I need it

  • No one cares, you buy it temporarily from the one who has it. And next time you may be the one who has it, and he may buy from you.

    Do they produce coffee beans in your country? No? Were you ever worried about not having enough coffee?

  • With proper system design this becomes a non-problem. This adds cost, but done properly it's cheaper than a system based on nuclear, especially going forward as renewable and storage costs continue their relentless decline (at a pace nuclear could only dream of).

    In more detail: you want two kinds of storage, one optimized for daily charge discharge, and one for long term storage, to handle different frequencies in the power spectrum of the power-demand mismatch curve. The first is batteries, and the second is various techologies (like thermal or hydrogen) that will be brought into play for the last 5% or so of grid decarbonization.
