One thing I thought was interesting is how he said (starting at 49:00) that the mass-move towards zero-carbon is not going to be motivated by fear of climate change or running out of oil but that it will be driven by cheaper energy and better/faster/cheaper cars. He is so right. Too high of a percentage of people don't care about any of those environmental issues. All they care about is how much it will cost (or save them) and how much it will inconvenience them (or not). Once electric cars and solar get cheaper (and they will), the masses will come flocking. It's kind of shame because you can't put a price on the environment, but unfortunately, that's how most people think.
