The Future of Energy
The technologies that we need to transition to a more sustainable global economy are there or thereabouts. We've got the wherewithal to create an energy supply but it's worth nothing if we keep on growing our energy demand in the way that we are at the moment. The big deal is solar at the global level, that's the biggest by far. Then we have this energy, most of it in the wrong parts of the world at the wrong time of year for the people who need it. And then we need to be able to use hydrogen, basically hydrogen and electricity for all our energy needs. That's mainly doable but we've got some crunch points.
