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)

  • EVs are rare (in the context of total energy consumption, even more so because not so many models offer this feature), limited to houses (what do you do when you live in a flat?) and not a reliable source - "honey, I need to drive fetch some groceries, you won't have energy in meantime". How many houses with only EVs as energy storage are disconnected from grid? I bet the number is next to 0.
    OTOH EVs as energy storage can provide buffering to energy grid when properly connected. This feature has its place, but they can't be used for reliable storage.

    V2L and V2H are desirable features worth paying for. Grid sharing is not rocket appliances. In other thread, I showed how a 2nd EV that is barely used can pay for itself, but some static batteries are cheaper. 10kwh can power 2-5 homes overnight. Apartment units don't individually pay for exterior flood lighting. Mid to higher end cars have 50-100kwh battery packs. As an overall society, 80%+ of cars are parked somewhere at any time. The point of powering one house, applies to sharing for 1m houses.

    That's why we have all that power available, right? You guys keeping listing various technologies but it isn't they aren't available nowhere at scale. Even this feature is not that common among the cars of today.
    And 10kWh is nowhere enough during winter (and perhaps summer with A/C), perhaps for single not big house with heat pump. Good luck with big cities.

  • But in Europe they also burn coal, no? Or burning gasoline, natural gas, trash, anything.

    (chosen OECD because it makes the numbers easier to compare, and doesn't cherry pick EU countries which are actually better than places like the US)

    A lot less coal, which is about twice as bad as gas for CO2 emissions per kWh.

    Places like the UK have got rid of coal completely. The last remaining coal power station shut down last year. When you look at the graphs for the UK, we've actually reduced electricity consumption as a whole, despite a growing population and the growth of electric vehicles.

    Still plenty to be done about gas. I can see why China still uses enormous amounts of coal. They don't really have any oil, so it's the cheapest fossil fuel they have access to. In fact, cost is mostly why solar is getting popular, because it's become extremely cheap. You can't rely on it completely though, unless we all agree to turn off our power at night. Power storage is not a solved issue by any means.

    China also never embraced nuclear power. They really got big on the world stage right around the time Chernobyl happened, and it was already getting too expensive even then.

  • 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

    Actually energy from fusion reactors on Earth does make a lot of sense. Sadly we are advancing slowly there.

  • How much coal has China cumulatively used in its history compared to the US or Europe? Spoiler alert: much less. Almost as if countries in the process of developing used coal for a reason...

    To be clear: Are you saying China is in the process of developing?

  • What's the point of comparing coal if not for CO2? Most other forms of pollution from coal are local, not global, the international debate here is on climate change, a western-world inhabitant has no right to say what China should be doing with the local pollution. The discussion on coal is started because of its horrendous climate change potential, which comes exclusively from its cumulative CO2 emissions.

    But if you want to compare coal numbers, I ran the calculations using this source for US production and this source for China production. Downloading the CSVs from both sources, I get that the US has produced 85643270043 short tons of coal, which at 21GJ of energy per short ton amount to 496731 TWh, whereas China has extracted 617787 TWh, i.e. a bit below 25% more than the USA. Since China has 1411 mn inhabitants and the US has 340 mn inhabitants, i.e. China has 415% the population of the USA, China has along its existence as a country extracted about 1/3 as much coal per inhabitant than the USA.

    So yeah, China would have to literally consume twice as much coal as it's already consumed to reach US values of per-capita historical cumulative coal consumption.

    Now what will you come up with? Suddenly coal numbers don't matter anymore?

    Do you think I am here to hate on China or something? Your inital claim was:

    How much coal has China cumulatively used in its history compared to the US or Europe? Spoiler alert: much less.

    And when you looked at the numbers and you were clearly wrong, you moved the goal poast again:

    So yeah, China would have to literally consume twice as much coal as it’s already consumed to reach US values of per-capita historical cumulative coal consumption.

    Or 50% more to be at the level of the EU, using the Our World in Data numbers from 1900(thanks btw). Given current production, China would overtake the EU around 2040 in that metric.

  • Yes, something like that. Now, while you can theoretically install that many solar panels, the kicker is that you don't have nowhere enough storage. And even if you had that 10%, you could increase solar all you want, but the nuclear would be still running at 90MW because of the storage, or better, the lack of it. And because you would have a surplus of cheap solar power energy during the day - assuming more solar panels than 10%, it would erode more expensive nuclear one to become even more expensive.
    Basically if we solve storage, we can get rid of nuclear, but not before.

    I mean the UK has 6% of its energy over the year come from solar, and 30% from wind, and installations are only accelerating, so this amount of installed solar is far from unrealistic.

    Installing storage approximately doubles the LCOE of solar energy, so this is also feasible from a cost point of view as we get rid of dispatchable gas turbines.

    Basically if we solve storage, we can get rid of nuclear, but not before.

    I am not saying we should get rid of nuclear. I am saying we should keep some nuclear, also once we have got less gas and more storage. Does this resolve some things in this discussion for you?

    The important metric for the moral debate is cumulative CO2 per capita, because that's the whole reason why we're measuring coal production history, not because we hate coal per se.

    I showed you that, even moving to cumulative coal production, China still has 1/3 that of the US per capita, which is the important metric because why the fuck would we compare a country with 1.4bn inhabitants to one with 340mn without taking population size into account.

    So yeah, China still has a lot of margin for coal burning until they reach the evil levels of the US/EU, but thankfully they won't because they're the strongest country in renewables, producing essentially 100% of all solar panels in the world.

  • To be clear: Are you saying China is in the process of developing?

    Compare GDP PPP per capita. China is very much on a lower place than the US or Germany. China is very developed compared to, say, Philippines, but still developing when compared to Japan or UK.

  • It's not about regulation. China has almost the complete photovoltaic production of the world. Essentially all panels installed in the rest of the world are also Chinese. It's about a smart government knowing which technologies to pursue, instead of things like the Spanish "sun tax" of the 2010s that killed whatever solar industry there might have been in the sunniest country in Europe.

    It's about energy independence. The CCP doesn't give a fuck about the environment, but not having to bring in energy from out of country is high on any governments priority list.

  • Why is Polution per GDP a better measure? I don't care how much they export when they're killing the planet at a faster rate every year with no intentions to stop it. I will praise China and the rest of the world when they reimplement and follow through with plans to ethically lower the world population, such as investment in education especially for women and incentives or fines based on numbers of children.

    You should be pretty happy with China then. They have a replacement rate just over one. That's lower than the US or Europe.

  • Coal is unreliable and dirty.

    China use absurd amounts of coal and they're not slowing down. They're the worlds largest producer and consumer of coal. They're increasing use of all power generation types - coal, solar, nuclear.

    Yes. And go check the percentage of coal use over time. Coal is going up. Renewables are going up much faster.

    Yep. No issues there.
    The core problem is storage here. And until we have a solid plan how to deliver with proven technology present today, we have to build new and run existing nuclear power plants. The other option is gambling.

  • They were also responsible for 95% of the world's new coal construction (2023). With just 1/5th of the world population.

    I'll give them props for solar. They build a lot of it, and thanks to us outsourcing practically everything to China over the last few decades, they build most of our solar as well.

    95% of the world’s new coal construction (2023)

    China had the largest new coal construction in 2023 but it was far below 95%. I didn’t do all the math but it drops below 50% when you compare it to just the growth of the next three biggest coal producers.

    They build most of our solar but we’ve effectively banned it now. They’re not only growing capacity to produce renewables, they’re taking the outputs that were planned for sale here and installing them locally.

  • The important metric for the moral debate is cumulative CO2 per capita, because that's the whole reason why we're measuring coal production history, not because we hate coal per se.

    First of all greenhouse gases not just CO2.

    It is also a metric China will not want to use. Per capita annual emissions are already higher in China then in many Western countries. More so UN population forecast shows Chinas population falling much more quickly then that of the West.

  • Pollution per GDP is a bad measure. Mali has a high CO2 intensity, but the GDP per capita is low, so pollution is low. The best measures are emissions per capita in consumption and production terms. China is not a saint in either of those metrics, being rather close to the EU in both of them today.

    GDP is total production net of total consumption. It would be cool to compare it to those factors independently but don’t know of anyone who reports that data.

    I’m not looking to bestow sainthood upon any country. Just looking for the most accurate metric.

    It is also a metric China will not want to use. Per capita annual emissions are already higher in China then in many Western countries. More so UN population forecast shows Chinas population falling much more quickly then that of the West.

    First of all greenhouse gases not just CO2

    For cumulative that's debatable. CH4 is the second most important gas, and its half-life in the atmosphere is short enough that over spans of 100s of years it can decompose into CO2 which has a much lesser greenhouse potential.

    Per capita annual emissions

    See? Moving the goalposts. Moving from cumulative, the real important metric, to per capita current emissions during a renewable transition, because otherwise the data doesn't fit your preconceived, chauvinistic anti-china views.

  • It's about energy independence. The CCP doesn't give a fuck about the environment, but not having to bring in energy from out of country is high on any governments priority list.

    That's why China is working hard on the greatest desert reforestation projects in the world, and why it exports an insane amount of solar panels instead of keeping them for themselves.

  • Coal is unreliable

    How? I would've said coal is very reliable, it worked for over a hundred years.

    Unreliable may have been a poor choice of words.
    You can’t move coal around with pipes or wires. Someone needs to drive trucks full of coal to a power plant.

    The pollution from coal tends to have a lot of externalities that drag on the economy. Lost work days, faster equipment degradation, etc.

    They use coal but they have practical reasons to want to reduce reliance on coal.

    Trucks? If you move coal for a power plant using trucks you're going to need a lot of trucks, you use trains or ships instead, or just build the power plant next to the mine and use conveyor belts.

    Safe, yeah. Private, no. If you want to verify whether a user is a real person, you need very personally identifiable information. That’s not ever going to be private. The best you could do, in theory, is have a government service that takes that PII and gives the user a signed cryptographic certificate they can use to verify their identity. Most people would either lose their private key or have it stolen, so even that system would have problems. The closest to reality you could do right now is use Apple’s FaceID, and that’s anything but private. Pretty safe though. It’s super illegal and quite hard to steal someone’s face.

    it's only meant for temporary situations, 10 total days per year. I guess the idea is you'd use loaner PCs to access this while getting repairs done or before you've gotten a new PC. but yeah i kinda doubt there's a huge market for this kind of service.

    It is common in the military to give commissioned rank to certain positions for the higher pay grade. The fast tracking takes away from the belief everyone serving with you went through (roughly) the same basic training as you.

    A private company is selling cheap tablets to inmates to let them communicate with their family. They have to use "digital stamps" to send messages, 35 cents a piece and come in packs of 5, 10 or 20. Each stamp covers up to 20,000 characters or one single image. They also sell songs, at $1.99 a piece, and some people have spent thousands over the years. That's also now just going away. Then you get to the part about the new company. Who already has a system in Tennessee where inmates have to pay 3-5 cents per minute of tablet usage. Be that watching a movie they've bought or just typing a message.

    Only way I'll want a different phone brand is if it comes with ZERO bloatware and has an excellent internal memory/storage cleanse that has nothing to do with Google's Files or a random app I'm not sure I can trust without paying or rooting. So far my A series phones do what I need mostly and in my opinion is superior to the Motorola's my fiancé prefers minus the phone-phone charge ability his has, everything else I'm just glad I have enough control to tweak things to my liking, however these days Samsungs seem to be infested with Google bloatware and apps that insist on opening themselves back up regardless of the widespread battery restrictions I've assigned (even was sent a "Stop Closing my Apps" notif that sent me to an article ) short of Disabling many unnecessary apps bc fully rooting my devices is something I rarely do anymore. I have a random Chinese brand tablet where I actually have more control over the apps than either of my A series phones whee Force Stopping STAYS that way when I tell them to! I hate being listened to for ads and the unwanted draining my battery life and data (I live off-grid and pay data rates because "Unlimited" is some throttled BS) so my ability to control what's going on in the background matters a lot to me, enough that I'm anti Meta-apps and avoid all non-essential Google apps. I can't afford topline phones and the largest data plan, so I work with what I can afford and I'm sad refurbished A lines seem to be getting more expensive while giving away my control to companies. Last A line I bought that was supposed to be my first 5G phone was network locked, so I got ripped off, but it still serves me well in off-grid life. Only app that actually regularly malfunctions when I Force Stop it's background presence is Roku, which I find to have very an almost insidious presence in our lives. Google Play, Chrome, and Spotify never acts incompetent in any way no matter how I have to open the setting every single time I turn Airplane Mode off. Don't need Gmail with Chrome and DuckDuckGo has been awesome at intercepting self-loading ads. I hope one day DDG gets better bc Google seems to be terrible lately and I even caught their AI contradicting itself when asking about if Homo Florensis is considered Human (yes) and then asked the oldest age of human remains, and was fed the outdated narrative of 300,000 years versus 700,000+ years bipedal pre-humans have been carbon dated outside of the Cradle of Humanity in South Africa. SO sorry to go off-topic, but I've got a big gripe with Samsung's partnership with Google, especially considering the launch of Quantum Computed AI that is still being fine-tuned with company-approved censorships.
