take robert boyle. boyle was perhaps the most eminent scientist in england in the generation just before isaac newton. he was immensely rich, a tall, skinny, kind-hearted man curious about nearly everything in the world. one of the things he was curious about was hangings. hangings in london in the 1600s were a big crowd pleers, a popular event. there were hanging days, eight of them a year. you'd get 20,000 spectators gathered around to see. rich people would sit in the bleachers, the poor would have to stand and jostle for space. the gallows could hold 24 swaying bodies at a time. nobody had any qualms about hangings, i should say. in this era there already were liberals and conservatives, but nobody was against hanging. the difference came to be that the liberals thought that if someone was being hanged, it was okay for his friends to rush up and grab him by the legs and tug him down to speed up his death, to make for a merciful death. but the conservatives thought that was much too soft. they didn't,

so it's even as concentrated in terms of supply as boyle so we can really kind of replacing one set of dependence with another set of dependence ok robert i mean it's go down the road here of renewables because a lot of people are saying that again i've come across very different numbers about the efficiency of investment in renewables as compared to fossil fuel and nuclear energy. sure well two to benjamin's point about efficiency look no one is opposed to efficiency saying you'd be opposed to efficiency is akin to saying i'm opposed to air the world is be is getting more efficient in its history consumption it's happening everywhere the us is now today using about the same amount of oil as it did in one thousand nine hundred eighty three despite the fact that we have twice as many cars and we're driving them to try says many miles so i'm all for efficiency but we can't keep the lights on with efficiency we have to generate electricity why because we don't have a perfect storage method for electricity if we had such a method then that is the true game changer but with regard to renewables look at the just the latest report from the ene
