Energy Doesn’t Flow in Wires — Leonard Susskind

Energy doesn’t flow in wires. Yes — according to the electromagnetic theory developed by James Clerk Maxwell and formalized through the Poynting Vector by John Henry Poynting, electrical energy flows through the electromagnetic field surrounding the wire — not inside the copper. In this deep physics documentary inspired by the thinking style of Leonard Susskind, we break down: • Why electrons move too slowly to power your home • The real meaning of the Poynting Vector • How Maxwell’s Equations redefine electricity • Why transformers work without direct wire connection • How wireless charging proves energy lives in fields • The deeper connection to Quantum Field Theory • Why electromagnetic energy exists in Space-Time When you flip a switch, a field configuration reorganizes at nearly the speed of light. The bulb lights up because electromagnetic field energy converges on it from surrounding space. Electricity is not electrons flowing like water. It is structured energy in fields. If you want to truly understand how electricity works at a fundamental level, this video will permanently change your mental model.
