    The interesting bit was about the energy usage of the credit card data centre.
    This does not take into account the energy usage of the terminals and data connection.

    I think the whole article is a bit silly.

    There was something similar about an WWW search using as much energy as making a cup of tea.

    Would that be true? It's quite a shocking re-adjustment, to realise that apparently the dematerialised processes that have replaced things like snail mail and bookkeeping, are not lightweight but really energy-intensive. That may not matter, in a future world of limitless renewable energy - and efficiency may improve (but why should it in that kind of future?)

    It's certainly true that biological processes are orders of magnitude more efficient than mechanical (or electrical) equivalents, as yet. So I'd easily believe that I could search a library using less energy than a search engine. But it would take me a lot more than a cup of tea to search the entire Internet.

    Posted By: SteamyTeaThe interesting bit was about the energy usage of the credit card data centre.

    Did the article actually state anything useful about that?

    It's not surprising that bitcoin uses a lot more energy. Credit card processing is about efficiency and although I doubt they're particularly concerned about energy usage, I'm sure that a concern flows out of their overall concern about elapsed time and data centre costs. By contrast, bitcoin makes a virtue out of the difficulty of 'solving' each block of transactions and of having as many computers as possible competing to solve the problem.

    But unless and until bitcoin or a replacement comes up with a solution that explicitly considers energy usage and minimises it as far as possible, there's no way that anybody who owns a bitcoin can consider themselves as green at all. The ideas of using renewable power to supply bitcoin mining miss the point - it's exactly the same as building regulations that allow people to offset inefficient building fabric with 'bolt-on' renewable extras. Adding to consumption instead of reducing our load on the planet.

    Data centres can stock holms with useful heat...
    house about that...

    What's the Vales' bk to say about this? Without buying and reading it.

    Which Vales' book to say about what, Tom? About whether or not criticism of one of their books is justified? About whether bitcoin is an energy hog? About whether Stockholm's district heating fueled by data centres can really be called 'green computing' or what?

    FWIW, I haven't read any of their books, so I for one am ideally qualified to answer your question without reading or buying any of them :devil:
