Last year China generated almost 3 times as much solar power as the EU did, and it's close to overtaking all OECD countries put together (whose combined population is 1.38 billion people)

Good on them. The earlier they can shut down those coal plants, the better.
They‘ll keep building more coal power plants in the global south and export coal. There‘s a lot of money to be made.

Solar and nuclear work just fine together. Nuclear is expensive (and most cost effective if kept running all the time, rather than switched on and off) but it reduces the cost of solar (lower proportion of solar means you don't need as much storage) and hedges against bad weather.
You can't just switch it off and on. It runs at more or less full power all the time. So tell me, at what power is that taking into consideration that sun doesn't shine during night + mornings and evenings when days are short or cloudy?

I don't understand what you're asking, sorry.

Last year, China generated 834 terawatt-hours of solar power.
Which is more than the G7 countries generated, and more than the US and EU combined. In fact the only country group that generates more solar power than China is the OECD, all 38 countries of it.

People talk about China's energy use like it's not* their* energy use. They used that power to produce the stupid shit that you bought, dumbass. You're responsible for that energy use, despite it being generated in China.

The question is simple. If you have installed solar power of 40% your country peak use, how much nuclear power you need - assuming simplified you have only these two power sources.

It is strategic necessity for China for energy security and for their own environment. Their predominant source of electricity has been coal which they have abundant of but is polluting the air they breathe. Does anyone recall the issues they had at Beijing Olympics? They have insufficient sources of oil and gas domestically. Alternative energy sources are their best domestic source of energy.

I'm curious how much of it they consumed though. I read recently the UK keeps on paying Wind farms (for example) to NOT supply the grid as they don't need it at certain times, and it wasn't going into batteries for later either. Just generated and...gone?
They pay the windfarms when too much power is generated for the grid to handle. The wind turbines are then throttled accordingly and the windfarm owners are reimbursed for the lost potential. At least that's how it goes in Germany. It's kind of an incentive to upgrade the power grid.

Do explain, I'm all ears.
No. I type less.

I think they don't get that your comment is fighting the same fight by being pro solar & anti coal/gas.
Unless you meant keeping the coal and gas plants, which really should be turned off and ended at this point. They're just sources of lung cancer & emissions
No. We get exactly what his comment is about.
If he was in the renewables camp, there would be no point, in this discussion over solar, to bring up nuclear. It's absolutely unrelated.
What he's doing is pushing the thought into people's heads that nuclear is a good solution, and that's why I'm calling him out for. For being a shill.

Yes, of course I've meant it in a positive way - a way to replace coal and gas. But solar is not just positive, they are problematic when you couple them with nuclear for the simple reasons that solar is not reliable and you can't throttle nuclear - they are like big ships, they require a lot of time to steer. Furthermore solar energy low price causes problems for nuclear higher prices. Which wouldn't be a problem if solar was reliable and continuous (long winter nights much?). But it's not, but you still need a reliable energy source. And so on.
The pro solar panel crowd don't understand many of these implications and go with simple "idiotic" and downvotes.Why wouldn't solar and other renewables combined with batteries be better?
It's very early days, yet California recently had 98 days on renewables. That started in winter.
What is it about renewables with batteries that you believe will fail, despite the mass adoption that is under way?
Why will the projected, continued decline in battery prices and advances in battery tech not occur?
Why would adjacent solutions, like the massive storage ability of vehicle-to-grid, be worse compared to nuclear?
Why are so many "in the know" getting it so wrong?

I'm with you on solar. We literally have a fusion reactor at the core of our solar system, so there's no point in having ones on earth. And the more we use solar, the more it'll be improved through research.
There's no argument for any carbon based fuels

This is legit true IDK why you're getting downvoted. Just because it doesn't show on US energy usage, every time you buy stupid shit you don't need like an automatic corn dog maker or a taco holder shaped like a sombrero that holds a shot glass in the middle, that has a real cost in terms of CO2 and that is done in China.

Good for China on that!
To add some perspective, China is about 2 and a quarter times as large as the EU nations, and according to currentresults.com seems to get a bit more sunshine than the EU does. So the difference isn't quite as stark as this post makes it seem.
But still, it's good that China is taking solar power seriously. I didn't realize they were doing that well.

What batteries are you referring to? Do you realize the amount of energy those batteries would have to store? Perhaps somewhen in the not so near future, but today? Go ahead and show me a western city able to store a couple of days worth of energy. More realistically a week.

China also continues to increase coal generation by more than renewables.
I don't believe this:
China | Energy Trends | Ember
Explore the latest data on China’s energy transition. How clean is China's electricity? How much renewable electricity does China generate?
Ember (ember-energy.org)
In 2024, China approved 66.7GW of new coal-fired capacity, started construction on 94.5GW of coal power projects
Even if you add these 2 together and pretend they were finished the same year it's not even close to:
China’s renewable energy sector made remarkable progress in 2024, adding 356 gigawatts (GW) of wind and solar capacity
China’s Energy Production: Coal and Renewables Locked in Competition Amid Clean Energy Boom
China’s energy production strategy in 2024 has been marked by both an unprecedented surge in renewable energy and a persistent reliance on coal, according to a new analysis by two think tanks, the Global Energy Monitor and the Centre for Research on Energy and Clean Air (CREA).
The Asia Live (theasialive.com)
They have missed every single renewable target and goal they’re set.
I don't believe this is true either unless you are referring to some other targets?
In 2020, China set a goal to install at least 1,200 gigawatts (GW) of solar and wind power by 2030. By the end of 2024, China had already surpassed this target, reaching this milestone 6 years ahead of schedule. This was made possible by aggressive investments, government policies, and a surge in solar and wind installations.
China’s solar capacity grew by an incredible 45.2% in 2024, adding 277 GW. Wind capacity also saw a strong increase of 18%, with an additional 80 GW installed. Overall, total power generation capacity rose by 14.6% in 2024, driven mainly by renewables.
China’s Renewable Energy Boom: A Record-Breaking Shift or Still Chained to Coal?
China has surpassed its 2030 renewable energy goal six years early, leading global clean energy growth. But coal reliance remains a challenge.
Carbon Credits (carboncredits.com)
China is only %27 renewables while the EU is 47%.
Don't worry, just like everything else I'm sure that will flip in the future
Europe has plenty of money apparently to suddenly:
NATO leaders on Wednesday confirmed their commitment to more than double defence spending by 2035 banding words like "crucial", "momentous" and "quantum leap"
Defence up to 5% GDP, Ukraine, Russia: Key takeaways from NATO summit
The summit ended with a commitment to spend 5% of GDP on defence - more than double the current target of 2%.
euronews (www.euronews.com)
Just why does it take an emergency to make some proper progress:
Global energy storage owner-operator BW ESS and Spanish energy storage developer Ibersun say a new joint venture is intended to build eight four-hour battery projects across the country, with a combined capacity of 2.2 GW, 8.8 GWh.
“No time to waste:” Huge big battery plans unveiled for Spain as accusations traded over blackout
Two battery storage companies unveil plans for eight big projects in Spain, as the government, regulator and power companies trade accusations over cause of blackout.
RenewEconomy (reneweconomy.com.au)
Where will the batteries be made I wonder?
On top of this energy prices in the EU are ridiculous and for some reason they still can't get off the gas, which leads to an unreal point of France giving more money to Russia for gas than in aid to Ukraine, so they have high energy prices and they're funding Russia's invasion of Ukraine and their companies and manufacturing are leaving them... to go to China...
But I appreciate your scepticism (I gave your post an upvote because China does sometimes get a little bit too much credit), they are the worlds top producer of CO2 by FAR but I do want to address
Greenwashing
This is something I've wanted for a while:
It requires EU importers to pay a levy corresponding to the embedded carbon emissions in 303 emission-intensive products
I've long disliked that places like the EU and the rest of the west can export their dirty manufacturing over to China where companies take advantage of lax or no environmental regulations, it's a false economy and makes the west look a whole lot greener and cleaner than it would if we were manufacturing what we used back at home

edit: boy I sure do love to procrastinate and talk about energy and co2 instead of studying
China approved 66.7GW of new coal-fired capacity, started construction on 94.5GW of coal power projects
New power plants don't mean using those power plants. Resilience/backup power. Use of coal for electricity has declined despite new coal plants.

They also expanded coal power, roads, and removed their population limiting policies, though. They produce about 3 times as much CO2 per person as India, Indonesia, and many South American nations, likely many nations in Africa as well but theres a lot of missing data.

They‘ll keep building more coal power plants in the global south and export coal. There‘s a lot of money to be made.
They're also actually still building more coal power in mainland China.

The question is simple. If you have installed solar power of 40% your country peak use, how much nuclear power you need - assuming simplified you have only these two power sources.
In a market or effincient economy, where peak occurs mid hot summer day, 100% solar dominated renewables makes sense. In Spring and fall, EVs can absorb daily oversupply and profit from trading back at night. Winter is when solar can fail to meet heating and electricity needs, and so either backup energy sources or having much more than 100% peak demand in order to make green H2 that can be exported to where it gets cold is needed.
0 new nuclear is best amount of nuclear for any economy.
