> Do you use a dishwasher? You should. They use less water and less energy per wash then any human washing by hand. I knew it was less water, but I'm unclear on less energy. Is it just because it uses more energy to purify and/or heat the added water? Because otherwise it seems like a lot of the energy is human energy, of which humans are generally already too sedentary anyway and could use with spending more of their energy on various activities. I agree with your other comments, and I don't doubt you're right about the other, just curious why that's the case.
