Bitcoin Mining Emissions In China Will Hit 130 Million Tons By 2024 (newscientist.com) 106

Posted by BeauHD from the what-to-expect dept.
According to researchers in Beijing, China, the total carbon footprint of bitcoin mining in the country will peak in 2024, releasing around 130 million metric tons of carbon. This figure exceeds the annual carbon emissions of countries including Italy and the Czech Republic. New Scientist reports: By 2024, bitcoin mining in China will require 297 terawatt-hours of energy and account for approximately 5.4 per cent of the carbon emissions from generating electricity in the country. The researchers predicted the emissions peak in China in 2024 based on calculations of when the overall cost of mining -- the investment in computing equipment and the electricity costs -- outweighs the financial rewards of selling mined bitcoin. They used both financial projections and carbon emissions analysis to model the emissions footprint in China, taking into account factors such as location. Bitcoin miners in Beijing or other parts of northern China are very likely to be using electricity from coal-powered plants. Mining in southern provinces -- especially Guizhou, Yunnan and Sichuan -- is in large part powered by hydroelectricity, says Guan. The findings have been published in the journal Nature Communications.

    Okay, this should be obvious, but... this will only happen if it makes economic sense to mine the coin. My back-of-the-envelope calculations suggest that 297 TWh of energy should run somewhere in the neighborhood of $29 billion (to within a factor of 3 or so), so it only makes sense if you can mine enough coin to cover that cost plus your time and other costs.

    That's... a lot of scratch. If the price of bitcoin falls, then this doesn't cost out for miners any more.

    I'm not saying the events in this paper can't happen (though I think it's ludicrous), but that predicting the economics of bitcoin in 2024 is ridiculous on its face.

      Bitcoin mining relies on somebody else shouldering a significant part of the cost. Either by using a public utility which spreads the cost over all customers, or by making the rest us who use the atmosphere pay the price for the emissions in the form of climate change.

        Mining is a race to the bottom in terms of cost. Only few miners having the lowest expenses will be profitable and survive in the long run. So, mining can only be profitable when done with very cheap electricity. That's why a significant amount of mining is performed near hydropower dams in Sichuan, China, that produce more electricity than the local

      I admit I didn't check your links, just Wikipedia. It says China has 42 GW, with 10 GW more coming on-line soon, and 36 GW in plans after that. This would haul them up to 88GW out of 2200, or almost exactly 4% nuclear.

    Bitcoin transactions are performed by the miners and validated by the nodes, and miners and nodes can try to hide but they seem easy to find.

    The IP's have to be known to the upstream bitcoin network to perform work, right? Couldn't law enforcement simply create a bitcoin node, and then similar to how the RCAA went after bittorrent users by suing the IP's that downloaded their fake torrents, discover the IPs of the miners and transaction nodes and have their country's ISPs block all those IP's? Bitcoin would be dead in the water.

    I don't see Bitcoin surviving a country-wide IP ban. It would be tough to enforce in the USA, but in less liberal countries it seems easy to kill off crypto. Is there something I'm not seeing?

    • What makes you think politicians care? Was it their actions or their words that did it?

    • You can spin up a new node in minutes on any IP anywhere. There aren't servers and clients. There are nodes. Only a few nodes are really needed if the hashing difficulty is relaxed (the hashing difficulty is automatically adjusted periodically). The hashing difficulty scales itself over many, many orders of magnitude. Even though the networks total hash rate right now is staggering, that would not be necessary for the system to work if the number of nodes were reduced.
