Natiijada casharka

I can describe how burning fuels can be used to generate electricity.

Muuji qoraalka

Over half of the electricity in the UK is generated from the Sun, wind and falling water. Many power stations in the UK burn natural gas and oil to heat water into steam. The moving steam in power stations pushes turbines, which drive electric generators that produce electricity. Natural gas and oil are fossil fuels used in power stations; coal is no longer used in UK power stations. Natural gas, oil, waste and wood are fuels that produce greenhouse gases and pollutants when burned.
