Over the 19th and 20th centuries physical power, social power, and economies grew explosively. The main cause was humanity’s exploitation of fossil fuels. Sources of oil, coal, and natural gas – a vast underground storehouse of ancient sunlight – provided an almost magical and seemingly unlimited supply of energy to grow more food, provision more people, build more cities, and create more technologies. But this age of "more" also brought global warfare, consumerism, and overproduction. Improve your energy literacy with stories about pushing motor vehicles, enduring blackouts, and growing $10 tomatoes, and take a tour of history that visits ancient China, industrializing Britain, the Great Depression, the Cold War, and the Green Revolution. Resources mentioned in this episode include a juxtaposition of old and new city photographs, and Jason Bradford’s report The Future Is Rural. The song, "Brother, Can You Spare a Dime?" was written by lyricist Yip Harburg and composer Jay Gorney. For more information, please visit our website.
