German goals to cut greenhouse emissions by 65% by 2030 are likely to be missed, meaning a longer-term net zero by a 2045 target is also in doubt, reports by government climate advisers and the Federal Environment Agency (UBA) show.
People also think that nuclear is some sort of magical thing that provides cheap unlimited energy on demand, when really it’s an expensive, lumbering option, that is slow to construct and difficult to maintain. There’s a reason why even China prefers renewables over nuclear, and they have reactors for military research.
I don’t have to tell China they’re finding it out themselves. Yes, China leads in deploying nuclear, for various reasons. Energy, research, military. But despite this, renewables represents by far the largest investment and growth. Though China’s nuclear energy ambitions seem large, don’t forget, it’s a huge country. It’s just a small piece of the pie, the pie being dominated by renewables.
And yet, it’s backed up by studies showing that nuclear is faster for decarbonisation, S&P Global’s estimates for the massive growth of renewables vs nuclear indicating China’s preferences. But really, this is all part of China’s infrastructure push. The funding is going to renewables, but China is keeping a foot in the door for nuclear. At best, nuclear would work, in a majority renewables grid if they cut about 25% off the cost.
This relates to China because they’re literally by far have invested the heaviest in renewable energy. A good amount of their nuclear reactors are experimental and for research, some are looking at military applications for ships. Renewables growth in China far outstrips their nuclear efforts. As per what the original article I mentioned indicates. China isn’t serious about their nuclear plans, it’s a combined research, military, national pride thing. Unlike their renewables investments, which you can see outstrips nuclear today, and in the future from sources given, backed by scientific papers also given.
That’s not how renewables work. They don’t produce electricity on demand (at least not solar and wind), their energy output is dependent on the weather. If there’s no wind and no sun, they won’t cover any demand spikes. Which is why baseload power like nuclear is pretty much useless in combination with renewables.
What is actually needed is flexible power that can be quickly adapted to the varying output from solar and wind. This is currently mostly done with natural gas, which we’re trying to get away from. In the future, biomass, water and storage will cover that part, while demand response strategies will help reduce demand peaks during times of low energy production.
If there is no wind or sun, we’re facing a global apocalypse. There’s always wind or sun. You just need to capture it. Nuclear is not on demand either, most plants aren’t designed to be. Nuclear is designed to be baseload energy, which, for decades, has fallen out of favour in lieu of more flexible doctrines. Octopus Energy is doing quite a bit of work with AI and energy demand, using incentives to control public energy consumption, which reduces the backup you would need for renewables. Also, that study I referenced, presumes about a 25% decrease in cost of nuclear. Again, best case scenario for nuclear.
Growing plants just to use them for energy production is absolutely stupid and incredibly harmful, agreed. But there are types of biomass that are basically waste from food production or forestry. It’s not a ton of energy, but it may play a part somewhere.
Niche energy production methods don’t benefit from economies of scale, and may be cost-ineffective.
“Drill, baby, drill” thinking led us to this point with fossil fuels; it can be similarly disastrous with biomass. The availability of profitable biomass energy will likely tempt the rich to overuse it, resulting in an artificial global famine.
There is some evidence to suggest a small nuclear presence in an otherwise majority renewables grid, can be ideal. But this is the most generous position you can have for nuclear.
That’s true but couldn’t that also be said for the rare earth metals used in batteries to power phones and EVs?
No energy production is perfect. Just good to look at the pros and cons.
So we should back ourselves into a corner when we have alternatives, because we don’t have alternatives for everything?
Clearly that only matters with nuclear and magically doesn’t happen in any other case

You should probably tell China that, then…

Ah yes… The classic primary source of an op ed from CU Boulder, which isn’t exactly known for having a great Asian Studies program.

And this relates to China in particular, how? Chinese infrastructure is substantially cheaper than abroad because NIMBYs get fucked.

It’s almost as if that’s why the gold standard is a nuclear baseline with renewable to meet demand spikes.

No, we’re facing nighttime. That happens literally every day.
So who goes around switching off the sun and turning off the wind?
Oh good, biomass. Because there aren’t enough starving people in the world already.

Two problems with that:
