Electrification is the process of supplying electricity to homes, businesses, and systems. It allows people to use electric lighting, machines, and devices. Engineers, governments, and companies work to build and expand electrical systems. Electricity is delivered through networks such as power lines and grids.

Electrification expanded across cities, towns, and rural areas around the world. It began in the late 1800s and grew through the 20th century. Different regions developed electrical systems at different times.

Electrification made it possible to use many modern technologies. It is part of how energy is used in daily life. Today, electricity is available in many parts of the world.
