Sure, but I still think it's true that we could have done this without the technology if we had a functional Senate in the US and the stomach for small personal lifestyle changes. It's kind of silly that we don't. California could stop wasting huge amounts of water on almond farms, for example. We have more fuel efficient cars, but Americans are also driving larger cars than ever. We could stop buying bottled water in plastic bottles, but sales are higher than ever. Our use of renewables has increased significantly, but the use of fossil fuels has increased more over the same time period.
