Electric Nation

Our modern electric power grid has been called the biggest and most complex machine in the world — delivering electricity over 200,000 miles of high-tension transmission lines. Yul Kwon travels around the country to understand its intricacies, its vulnerabilities and the remarkable ingenuity required to keep the power on every day. At New York State's governing grid control room, he learns how a massive blackout cut power to 40 million Americans and joins a live wire repair team who do their daring repairs from the side of a helicopter in flight. He also visits the country's largest coal mine, rappels down the side of wind turbine, takes a rare tour of a nuclear plant and travels on a massive tanker — where Kwon reflects on the challenges and opportunities we face now and in the days ahead to keep the power flowing.
