Fun Fact 2: How wind is created? The Sun heats the surface of Earth, heating different parts to different temperatures. The land will heat up quicker than water. The air above the land is hotter than it is above the ocean. Hot air rises, therefore, the air above the land will rise higher more quickly. When the air above the land rises, the air above the water moves in and takes its place.
Fun Fact 3: What is the wind cycle? The wind moves in different directions depending on the various temperatures across the Earth. During the day the air above the water will move across the land taking place of the air which has risen. However, the opposite happens at night as the temperature of the air above the land decreases more quickly than across the water.
Fun Fact 4: Atmospheric winds are similar to daily wind cycles; atmospheric winds are created around the Earth as the Sun will heat the land closer to the equator more quickly than the land nearer to the North and South Poles.
Fun Fact 5: The speed of the wind varies across the world and changes throughout the seasons. These variables affect the amount of energy which can be produced; as more wind at higher speeds will generate more energy.
Fun Fact 6: The main type of energy generated by the wind in modern day is electricity.
Fun Fact 7: Windmills, wind machines and turbines generate electricity from the wind. Turbine is the name given to the modern day windmill.
Fun Fact 8: Wind turbines vary in size, they usually have three blades and they are often huge in size; standing as tall as twenty or so buildings! The blades can move at great speed, at more than 200 miles per hour (320 kilometres per hour)!
Fun Fact 9: The power of the wind turns the blades on a turbine. The blades start to rotate at speed which turns a generator. The generator converts the energy into electricity.
Fun Fact 10: The electricity produced from the turbine generators is used to power many different things including homes and businesses.
Fun Fact 11: The turbine system is very clever as technology and computer systems allow us to control the direction of the blades so that they work in accordance to the direction of the wind.
Fun Fact 12: Is wind energy a renewable source? Yes, it is a renewable source; this means it will not run out. The temperature across the land and water will always differ, which means that wind will always be produced across the globe.
Fun Fact 13: Wind energy can be used in different ways to power things. For example, it can be used to move the sails on a boat giving it motion and allowing it to travel across water.
Fun Fact 14: Wind energy has been used for many, many years. It was used way back in time for various functions including pumping water and grinding grain.
Fun Fact 15: Wind farms (groups of turbines) can be set up on floating structures offshore. When they produce electricity, it can be generated to land via cables under the sea.
