New research shows renewables are more profitable than nuclear power
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 Eur...

What about when the grid is almost entirely renewables? Is nuclear cheaper than just storage? What about storage one it's already been implemented to the point of resource scarcity?
No, nuclear is always more expensive in real world conditions. Places with mostly renewables plus in-fill from batteries and transient gas generation are a lot cheaper than nuclear. eg. South Australia.
But transient gas generation produces much more ghgs than nuclear, and when accounting for the ghg potential of metanen and normal pipeline leakage, it is even more damaging than coal.
Except overprovisioning your total load by 30% with nuclear capacity doesn't allow turning the transient gas off
It's required less and less as other forms of generation are added to the mix. eg. Tidal and pumped hydro.
1kg of lithium produces about 10kWh of storage for 15-20 years. 3-12 hours of storage is plenty for a >95% VRE grid.
1kg of uranium produces about 750W for 6 years.
There are about 20 million tonnes of conventional lithium economically accessible reserves (and it has only been of economic interest for a short time).
There are about 10 million tonnes of reasonably assured accessible uranium (not reserves, stuff assumed to exist). It has had many boom/bust cycles of prospecting.
Lithium batteries are not even being proposed as the main grid storage method.
Cobalt is the difficult one, especially with the child workers mining it.
Cobalt isn't even in most EV batteries anymore, and LMFP is replacing NMC next year.
Sodium ion will then replace LFP the year after.
It's also real weird how people only ever care about french colonial exploitation of africa when it comes to materials they pretend are in renewables and not when they're flooding villages drinking water with uranium tailings.
