The central facility where fuel or flowing water is converted into electricity at industrial scale — the place where the abstract idea of 'energy policy' becomes concrete, where a building full of spinning turbines whose fuel choice, multiplied across a grid, decides how much carbon a civilization emits.
On September 4, 1882, a switch was thrown in a building on Pearl Street in lower Manhattan, and electric lights came on for about eighty-five customers in the surrounding district. Thomas Edison's Pearl Street Station was a small coal-fired facility — less than a city block, serving a radius of about a mile. But what it introduced was something new: the central station, a single place where power was made and sent outward to many customers at once. Before Pearl Street, anyone who wanted electric light had to run their own generator. After it, the idea that power is made somewhere else and delivered to you — that electricity arrives, the way water arrives — became the organizing fact of modern life. The choice of what burns or falls or splits inside that somewhere-else has turned out to be one of the most consequential decisions any civilization makes.
