Renewable energy
A The Three Gorges Dam is the biggest dam in the world. It took more than 10 years to build. China is the country that makes the most electricity from hydropower.
B Some of the world’s biggest wind turbines are off the coast of Britain. Their blades are bigger than the London Eye! One turn powers a house for around 29 hours!
C One of the biggest solar farms in Australia is on a sheep farm. Thousands of solar panels make about 200 million hours of electricity a year. They also protect the sheep from sun and rain!
D Iceland has a lot of volcanoes which produce hot water and air. So about 30% of the country’s electricity comes from geothermal energy. It’s very cheap!
E The USA grows the most biofuels, usually corn. Most cars there can use 10% vegetable fuel mixed with oil. Many cars can just use biofuel.
