The massive computer clusters powering artificial intelligence consume vast quantities to answer the world’s queries, but how is Big Tech redressing the balance?

    Datacenter LLM tranches are 7-8 H100s per user at full load which is around 4 kW.

    Multiply that by generation time and you get your energy used. Say it takes 62 seconds to write an essay (a highly conservative figure).

    That’s 68.8 Wh, so you’re right.

      Well that’s of the same order of magnitude as the quoted figure. I was suggesting that it sounded vastly larger than it should be.

      kW is a unit of instantaneous power; kW/s makes no sense. Note how multiplying that by seconds would cancel time out and return you power again instead of energy. You got there in the end, though.
