>In total, bitcoin consumed nearly 1,600 billion litres - also known as gigalitres (GL) - of water in 2021, the study, published in the journal Cell Reports Sustainability, suggests.
It's too bad the study isn't linked, but the math seems a bit fudged to me. Maybe they're using the amount of water per block (144 per day) which records multiple transactions?
For 2021 there were about 250,000-ish[1] daily transactions on BTC, so roughly 91 billion transactions. With 91 billion transactions using 1600 billion liters of water you get about 18 liters of water per transaction instead of the 75,000 or so liters a pool is.
If you assume a 24 x 12 x 4 pool and use blocks instead of transactions, each block uses about as much water as a pool.

- tripplyons 3y agoI agree. Measuring per-transaction mining work seems like a bad choice of metric because mining uses blocks of transactions. Maybe someone mixed up the two.
