What is the difference between energy and power? How does the power grid work? And what’s the difference between a megawatt and a megawatt-hour? 


On this week’s episode, we answer those questions and many, many more. This is the start of a new series: Shift Key Summer School. It’s a series of introductory “lecture conversations” meant to cover the basics of energy and the power grid for listeners of every experience level and background. In less than an hour, we try to get you up to speed on how to think about energy, power, horsepower, volts, amps, and what uses (approximately) 1 watt-hour, 1 kilowatt-hour, 1 megawatt-hour, and 1 gigawatt-hour. 

 

Shift Key is hosted by Jesse Jenkins, a professor of energy systems engineering at Princeton University, and Robinson Meyer, Heatmap’s executive editor.
