Wouldn't it be better to just go with nuclear? Isn't this a gigantic waste of space and overhead to maintain it? And how "renewable" are the materials used to produce these?

Take too long time and cost. I honestly perplexed by the fethism towards Nuclear Power Plants. Have you seen the delay and bloating cost of Olkiluoto, Flamanville and Vogtle?

Nuclear Power Plants are only good too spread the cost of maintaining strategic nuclear jobs and industry and some hope that nuclear space propulsion could be available later.

There's two big parts of the earth that are uninhabitable because of nuclear.

Anyway, they are going with nuclear too.

I don't think the characterisation of this as waste of space is correct. There's a growing body of research suggesting that solar panels are compatible with grazing animals and farming, and the wind farms don't really stop usage of the space unless you are planning to go ballooning.

https://www.worldnuclearreport.org/Power-Play-The-Economics-...:

“According to the U.S. Energy Information Administration, the LCOE for advanced nuclear power was estimated at $110/MWh in 2023 and forecasted to remain the same up to 2050, while solar PV estimated to be $55/MWh in 2023 and expected to decline to $25/MWh in 2050. Onshore wind was $40/MWh in 2023 and expected to decline to $35/MWh in 2050 making renewables significantly cheaper in many cases. Similar trends were observed in the report for EU, China and India.”

I think the only thing that may be able to beat this is nuclear fusion, and that’s hypothetical at the moment.

And even that may be undesirable. If fusion requires huge plants, it may put power (literally and figuratively) into only a few hands.

Recycling of solar panels and glass-fiber wings is an issue, though.

They've got a huge amount of space, solar has a low cost and provides an additional consumer to build out yet more capacity for supplying the world.

If this is legit : https://world-nuclear.org/information-library/country-profil... then they have 59 reactors right now with 37 currently in production. Wikipedia lists 62 reactors being built in the world in total, and 28 of them being in China. The amount of power those additional plants will generate will take them from third in the world to second this year (wikipedia) and in total would pass the US when built.

They're not slouching on nuclear, they're ramping up energy production at an incredible pace on a lot of fronts.

This construction of wind and solar has nothing to do with renewable, and everything to do with China's desire to get as much electricity generation as possible, which involves increasing nuclear, coal, hydro, and everything else.[1]

Only if you want the spicy radioisotopes. For some people that's a benefit, for others that's a problem.

Who controls the spice, controls the ~~universe~~ nuclear deterrent.

If all you care about is price, the combination of PV and batteries is already cheaper, and builds out faster.

> Isn't this a gigantic waste of space and overhead to maintain it?

No. Have you seen how big the planet is? There's enough land for about 10,000 times current global power use.

If your nation has a really small land area, e.g. Singapore, then you do actually get to care about the land use; China is not small, they don't need to care.

> And how "renewable" are the materials used to produce these?

Worst case scenario? Even if they catch fire, that turns them into metal oxides which are easier to turn back into new PV than the original rocks the same materials came out of in the first place.

Unlike coal, where the correct usage is to set them on fire and the resulting gas is really hard to capture, and nuclear, where the correct usage is to emit a lot of neutrons that make other things radioactive.

Why can't you do both? Why does it always have to be either or?

But for economics. Renewables are simply the cheapest option for generation.

For reduced land use, and hence reduced impacts (overall) on the environment and agriculture, nuclear wins hands down. But decades-long lead times, radioactive waste disposal, encumbering safety regulations, water supply etc. etc. etc. are problems you don't have with renewables.

China has also just launched a megawatt scale wind generator a the helium-lifted balloon, the S2000 , they have active thorium rector the TMSR-LF1 and GW/h Vandium flow battery. The scale , speed and breadth of what they are doing is incredible and I think missed my people
