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)

  • You're comparing GDPs in dollars, not PPP. Your calculation is invalid because of that. Since cost of life in China is several times lower than in the USA, pure GDP metrics in dollars are a bad comparison unless you convert them to purchase power parity (PPP), which gives a much more comparable metric in terms of amounts of goods/services manufactured and traded than straight GDP. Run the calculation again using PPP adjusted GDP and tell me your findings.

    I am not comparing them with USD, the user who brought up GDP did because their source specifies it.

  • I think that you misunderstood his comment. He's not criticizing solar energy, he's calling out China's green washing as they have the same solar production per Capita than Europe but they have way more coal production per Capita than Europe.

    A right wing politician would throw a fit about how solar energy is dangerous and make kids trans.

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

  • Maybe that is because I have the elementary school education necessary to understand that burning coal and gas also causes emissions. So when I am looking at cummulative coal consumption, I have the very basic common sense to not look at CO2.

    EDIT: Btw 2/3 of EU emissions happened in the last 60 years. So this very likely shows most of the EU coal consumption. Also if you happen to have actual coal numbers and want to share them, I am happy to have a look at them. But please no CO2 = coal bs.

    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?

  • If you trade too much EV energy during night, then you can't drive during the day. And again, EVs capacity is not reliable at all. As per green H2, please show me a production and a storage capable of providing energy to a city. Or at least a real project that's building it. Storing H2 is a big problem, like a huge one. If nothing else, Hindenburg tells a story. The fact that energy loss is at more than 50% when producing green H2 is a minor problem compared to storage.

    You need H2 only after solar + EVs provides more than 24 hours of needed energy in an area. Although H2 does save on transmission costs for medium to long distance. One of the remarkable aspects of BYD Dolphin, now under $9000 for 32kwh battery is that the battery value alone is $260/kwh capacity, and if you never drove it, but sold electricity 2.6c/kwh higher at night than you pay at day, then you pay for the car in its entirety. Just batteries can be sold under $100/kwh in China, and you could make 200% ROI from 3c/kwh price differential. EVs and batteries can be paid by private sector instead of utility investment markup model.

    H2 technologies are advancing, including storage and pipes. Electrical transmission is more than 10x more expensive than transmitting gas/H2, and saves money on that end relative to efficiency loss. Surplus solar with input cost at 2c/kwh or less achieves under $2/kg H2 target which is equivalent driving distance to $1/gallon gasoline, and 10c/kwh electric only value delivered energy, and 6c/kwh combined heat and electricity value.

  • I am not comparing them with USD, the user who brought up GDP did because their source specifies it.

    You're right, you're referring to the original source, which is supposedly already in PPP dollars, so I deleted my previous comment. Thanks for the correction. Regardless, that data is 2011, so it's kinda useless to me because that's before the energy transition of China.

    EVs provides more than 24 hours of needed energy in an area

    Only if it was fully charged, you don't drive with it and you live in a house. And thus are not a reliable energy source at all, even less for general energy problems.

    H2 technologies are advancing, including storage and pipes.

    All technology is All technologies are advancing, but do you have a solution today? And even with advancements, you'll hardly solve H2 flammability. Even keeping it contained is problematic.

  • I think that you misunderstood his comment. He's not criticizing solar energy, he's calling out China's green washing as they have the same solar production per Capita than Europe but they have way more coal production per Capita than Europe.

    A right wing politician would throw a fit about how solar energy is dangerous and make kids trans.

    They burn more coal than Europe because there's more energy demand in Europe and solar alone can't fulfil it. Which is also the same in Europe.

  • 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.

    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?

    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.

    Same, especially when searching technical or niche topics. Since there aren't a ton of results specific to the topic, mostly semi-related results will appear in the first page or two of a regular (non-Gemini) Google search, just due to the higher popularity of those webpages compared to the relevant webpages. Even the relevant webpages will have lots of non-relevant or semi-relevant information surrounding the answer I'm looking for. I don't know enough about it to be sure, but Gemini is probably just scraping a handful of websites on the first page, and since most of those are only semi-related, the resulting summary is a classic example of garbage in, garbage out. I also think there's probably something in the code that looks for information that is shared across multiple sources and prioritizing that over something that's only on one particular page (possibly the sole result with the information you need). Then, it phrases the summary as a direct answer to your query, misrepresenting the actual information on the pages they scraped. At least Gemini gives sources, I guess. The thing that gets on my nerves the most is how often I see people quote the summary as proof of something without checking the sources. It was bad before the rollout of Gemini, but at least back then Google was mostly scraping text and presenting it with little modification, along with a direct link to the webpage. Now, it's an LLM generating text phrased as a direct answer to a question (that was also AI-generated from your search query) using AI-summarized data points scraped from multiple webpages. It's obfuscating the source material further, but I also can't help but feel like it exposes a little of the behind-the-scenes fuckery Google has been doing for years before Gemini. How it bastardizes your query by interpreting it into a question, and then prioritizes homogeneous results that agree on the "answer" to your "question". For years they've been doing this to a certain extent, they just didn't share how they interpreted your query.

    I spent way too long researching the morning. That industry implies a much greater population that is attracted to children. Things get more nuanced. People are attracted to different stages, like prebubesant, early adolescence, and mid to late adolescence. It seems like an important distinction because this is a common mental disorder. I was ready to write this comment about my fear that there's a bunch of evil pedophiles living among us who are simply deterred by legal or social pressures. It seems more like the extreme stigma of pedophilia has prevented individuals from seeking assistance and has resulted in more child sexual abuse. This sort of disorder can be caused by experiencing this abuse at a younger age. When I was religious, we worked closely with an organization to help victims of trafficking. We had their stories. They entered our lives. I took care of some of these kids. As a victim of sexual abuse when I was kid, I had a hatred for these kinds of people. I feel like my brain is melting seeing how there is a high chance of people in my life being attracted to children. This isn't really to justify the industry. I'm just realizing that general harassing people openly about it might not be helping the situation.

    I guess that's why you pay your soldiers. In the early summer of 2024, months before the opposition launched Operation Deterrence of Aggression, a mobile application began circulating among a group of Syrian army officers. It carried an innocuous name: STFD-686, a string of letters standing for Syria Trust for Development. ... The STFD-686 app operated with disarming simplicity. It offered the promise of financial aid, requiring only that the victim fill out a few personal details. It asked innocent questions: “What kind of assistance are you expecting?” and “Tell us more about your financial situation.” ... Determining officers’ ranks made it possible for the app’s operators to identify those in sensitive positions, such as battalion commanders and communications officers, while knowing their exact place of service allowed for the construction of live maps of force deployments. It gave the operators behind the app and the website the ability to chart both strongholds and gaps in the Syrian army’s defensive lines. The most crucial point was the combination of the two pieces of information: Disclosing that “officer X” was stationed at “location Y” was tantamount to handing the enemy the army’s entire operating manual, especially on fluid fronts like those in Idlib and Sweida.
