  • So you don't have an answer?

    My answer is that the difference is too small to matter. In straight energy to refine from ore terms, Ti takes nearly three times as much as Al per unit mass of metal, and the Al one probably uses less mass too, but that's still less than 100kWh difference per kettle, equivalent to about 2000 hot drinks

  • I’ve often wondered what the energy savings would be if people brewed their tea at, say 92 or 95c instead of a rolling boil.

    Someone I spoke to recently drew parallels between Western consumerism and responses to trauma. No matter how evident it is that we’re being self-destructive, we simply refuse to change because of reasons we can’t fully comprehend (on a societal level; there are exemplary eco-conscious individuals here and out there).

    There are two parts; just heating water from 92 to 100 costs about 9Wh per litre. Vaporising it is energetically costly, but not much is vaporised. Losing 0.01l as steam (that's a lot) would cost another 6Wh. Out of the 100Wh/l you're using to make tea either way, it's a material number but not earth shattering. All this assumes 100% efficiency, so the absolute number will be higher but the proportion is largely unchanged.

    The importance of this depends entirely on what the rest of the building is up to - if it's being heated, all of the input into the kettle ends up as reduction in required heating input so it doesn't matter

    Shit tea though,

    "Or, as Tom Williams puts it, “As soon as humans can interact with something, we mess it up.” We often boil more water than we need, using more energy than we need. We also do things like leaving the stove or microwave running after the water has already reached a boil."
