• Renewable Resource: they can be easily replaced and will not run out.
• Oil and Gas Formation: Earth's crude oil and natural gas is formed from marine plants and animals that died millions of years ago.
• Carboniferous Period: 360-299 million years ago.
• Jurassic Period: 201-145 million years ago.
• Wind: large windmills are called wind turbines.
• Biofuel: are made from crops.
• Hydroelectric: is a way of harnessing energy from running water.
• Solar: is energy from the sun.
• Geothermal: is heat from the Earth.
• Uranium and Plutonium are nuclear fields.
• When coal is burnt, it releases Carbon Dioxide, Sulphur Dioxide, and Nitrogen Dioxide into the atmosphere, contributing to global warming.
• C02 is a greenhouse gas that contributes to global warming.
• Photovoltaic cells: Are used to turn sunlight into energy.
