But the point McAfee is trying to do is that it requires less materials to do so. Yeah, energy consumption is on the rise, but instead of burning xx tons of coals to generate 1GWh like it did 50 years ago, it does so by using 10% of that coal. Advances in technologies allowed us to do that. In plus you cannot deny we do have a momentum to use more and more technologies involved in renewable then in fossils. I agree we are not quite there yet, but is way better then it was in the late 80's, beginning of 90's when the ozone layer hole was at its biggest.
