This.

Also, tie together more countries' power grids to even out production and demand of renewables, and reduce the need for other backup sources.

For a fraction of the cost of nuclear, increase the storage capacity as well. We've had days where the price per MWh was negative in many hours, because of excess production.

The barriers to carbon free energy aren't technical, they're purely political.

district heating is where it's at in 2024.

You don't have those in 2024? Commies built central heating in every city.

Still not a reason to not build them, the entire point is for nuclear to handle the load when solar/wind can't provide due to weather. Other renewables will still be producing the bulk of the power we need, but at night nuclear will be handling any demand spikes, each of them would greatly reduce the number of batteries required to satisfy the demand. They can stay until our solar output is so high we can just start electrolyzing water into hydrogen as energy storage.

You can make Thorium reactors much smaller and cheaper, basically a 50MW unit is not much larger than a shipping container, while being much more safe than standard nuclear plants. The largest issue is over-regulation of the nuclear power in general.

A 50MW of solar installation is HUGE, and thats 50MW at the sunniest part of the planet: https://newsaf.cgtn.com/news/2019-12-15/Kenya-launches-Chinese-built-50MW-solar-power-plant-MqC575l6Te/index.html, We are basically talking about close to a square kilometer installation...

there is simply no way to call a 50MW solar plant cleaner than nuclear and its probably not even that much cheaper in the end. Compare that to a shipping container sized reactor... Only thing in the way, is the nuclear scare and government regulations.
