In a recent study, researchers from the European Environmental Bureau (EEB), the Stockholm School of Economics (SSE), and the Potsdam Institute for Climate Impact Research (PIK) questioned the planned development of new nuclear capacities in the energy strategies of the United States and certain European countries.
Until we are able to sort out the cost/tech to make a green-sourced grid (such that the role of utilities is to capture surpluses from when the sun shines and the wind blows and sell it back when transient sources aren’t producing) nuclear is going to be an important part of a non-carbon-producing energy portfolio.
Already it’s cheaper to bring new solar and wind online than any other sort of electrical production; the fact that those are transient supply sources is the last major obstacle to phasing carbon fuels entirely out of the grid. If nuclear can be brought safely online it could mean pushing the use of fossil energy entirely into use cases where energy density is critical (like military aviation)
