Electricity

The harnessing of electromagnetic energy that reorganized how civilization produces and distributes power, enabling industrial production, communication, computing, and modern urban life.

Electricity did not just replace other energy sources. It was the first energy that could be generated in one place and used in another, scaled indefinitely, and converted into almost any other form of energy or information. Every network civilization depends on — from the internet to the power grid to financial systems — runs on it.
