Sort the fuels and energy generation methods by whether they are renewable (will not run out) or non-renewable (will run out).

• The vast majority of our energy comes from fossil fuels that are extracted from the ground. These are the remains of ancient forests and swamps that were buried many thousands of years ago. Over time, with pressure and heat, they got transformed into the energy-rich substances coal, oil and natural gas.
• The burning of fossil fuels is extremely harmful to the environment as it creates air pollution and adds massively to global warming which leads to climate change.
• Many different fuels are made from crude oil. These include petrol, diesel and aircraft fuel.
• It has never been more important to substitute fossil fuels for clean, 'green' energy sources. We can make electricity from nature's power sources - the wind the waves, the rivers, the sun and the heat under the ground.
• Biofuels involve burning oil and gas made from grown plants (and other organic matter) rather than fossilised ones.
