Electricity is made on a large scale in a power generating plant.
In British Columbia, we mainly use the power of falling water to make electricity, but we also burn natural gas. A power plant that runs on water power is called a hydroelectric power plant. A power plant that burns natural gas is called a steam or thermal power plant. In a hydroelectric power plant, water is used to turn a large wheel called a turbine. In a thermal power plant, fuel is burned to heat water to generate steam which turns the turbine.
