The document provides information about electricity generation and transmission. It discusses how electricity is generated through various methods like coal, nuclear, hydro, geothermal, solar and wind. It then explains how high voltages are used to transmit electricity over long distances through transmission lines before being stepped down through transformers for residential use. Diagrams show the simplified electric system and components involved like turbines, generators, transformers and transmission lines.

Energy Transmission
The voltage is increased to reduce
the energy lost as it is transferred
through the wires over a long
distance.
The voltage must then be reduced
to a value that is acceptable for
home usage.
