It's interesting how indoctrinated we've become to think of "energy and water" as waste instead of as a feature of an advanced, high-technology high-energy civilisation. If we had good sources of energy (nuclear, or solar+batteries) we wouldn't even need to worry about that. Water as well, water simply cannot get "wasted", you just need to clean it, which requires energy. The fact is, these "modern" "green" appliances are simply worse, sure they use less energy but waste much more time (because colder water -> longer wash cycle). You can get more (useful) energy, but you can never get more time.
