Electricity existed all along, but the system of devices needed to generate this force and distribute it to individual buildings was an invention, launched initially by Edison: He effectively turned electricity into a salable commodity and his Pearl Street station was the world’s first electric power station. Nikola Tesla’s invention of alternating current (AC) technology then made it possible to transmit electricity over long distances, leading to the nationwide grid we know today. Now, anyone in the West and throughout most of the world can tap into the grid to power everything from light bulbs to computers.
