Chemical energy stored in coal. This energy is transferred as heat and this energy is stored in water as steam. The energy in steam is transferred to movement in a turbine and to electrical energy in the turbine. (http://www.bbc.co.uk/staticarchive/83fd81e0d8e640d5f2d70f272e3d879aea278598.gif)This diagram shows an energy transfer diagram for the generation of electricity from a fossil fuel such as coal.

National Grid

Electricity is distributed from power stations to consumers through the National Grid, which allows distant power stations to be used.

Electricity is transferred from power stations to consumers through the wires and cables of the National Grid. When a current flows through a wire some energy is lost as heat. The higher the current, the more heat is…
