This is a great presentation. I wish that he'd said more about 60% of everything used via electricity being "wasted". I suppose that it's largely the Carnot cycle. Given that the major sources are coal, natural gas and nuclear. For coal and natural gas, that wasted energy means more than doubling CO2 emissions. But there's really no workaround, unless you use those fuels directly, and get all of your electricity from PV and wind. That would be a major change. Maybe, as he argues for petroleum, it's better to just not use that stuff as fuel. Just as chemical feedstocks. Edit: grammar
