I think Bill Gates is on to a really important issue. Energy is the foundation of modern life: the way we work, live, travel, communicate all requires huge amounts of energy. And energy is critical to job growth and wealth creation. People can't work in a factory if it's 100 degrees. If we don't want countries to burn a lot more fossil fuels in the future, we're going to need better technology to create the volume of modern energy that people in aspiring economies require. And wealthy, educated, healthy societies consume large amounts of energy. There are no rich countries that consume a little bit of energy.
