Trucks, trains, planes and boats move food, clothing, cars, wood, steel, medical products, smartphones, bicycles, organic milk, free-range chickens—basically all consumer goods. And energy is no exception. Coal is mined and then carried to where it is burned. Oil and natural gas are moved from where they are produced to where they can be refined into transportation fuels and myriad other products, and then moved again. Uranium is mined and transported to create fuel rods for nuclear power plants or nuclear-powered ships.
