So I finally watched that talk to the end (had only watched the beginning). I generally like Rosling, but that talk seems a bit low on details. Your interpretation seems wrong - washing machine people only use 2 units of energy, the rich use 6 units. So there seems to be a lot of potential to save right there. While more people will move up to washing machine level, at the same time things could get more efficient and more green energy could become available (it's not clear where Rosling gets his projections from...). Rosling seems to be angry at some economics students who he claims wanted to deny the world washing machines. You adopted his anger and now you think everybody who says "save energy" wants to deny people washing machines. There is simply no basis for that (and I wonder if those selfish economic students actually exist - Rosling is a cool guy, but also a show man, perhaps he invented them for a good story). Washing machines are actually not that sophisticated, by the way. I think the first ones even operated without electricity. It's basically a drum spinning in a bowl of water, with some fancy chemicals added to the mix. Perhaps somebody should invent a "3rd world washing machine" to help all those women out.
