| A diagram of a gas power station. |
- 1. Natural Gas is burned in a furnace.
- 2. Water is heated in a boiler by the burning gas.
- 3. Water turns to steam and passes down pipes to turn a turbine.
- 4. The turbine causes a generator to spin.
- 5. The generator makes an electrical current.
Advantages
- Can work continuously.
- Power supply can be varied quickly depending on demand.
- Few power stations needed to supply a large number of houses.
Disadvantages
- Cost of fuel.
- Produce Carbon Dioxide contributing to global warming.
- Other pollutants produced which can harm health or produce acid rain.
- Natural Gas will run out.
