How do wind turbines work for kids?
Wind is a renewable form of energy, unlike power that comes from oil. That’s because there is always more wind being created. Turbines are the machines that catch wind and turn it into energy that we can use.Cause of WindWhen the sun warms one part of the earth more than other parts, the air over the warmer parts rises. Cooler air rushes in to take its place. This motion creates wind.TurbinesA turbine looks like a large airplane propeller with two or three fiberglass blades mounted on top of a tall tower. There is more wind at the top of the tower than there is near the ground, so taller towers capture more wind energy. The blades are connected to a shaft that turns when the propellers spin in the wind.Making ElectricityInside the turbine, a generator gets power from the turning shaft. A set of gears increases the speed of rotation as the shaft connects to the generator, which converts the power into electricity.Storing PowerIn “Wind Power of the Future: New Ways of Turning Wind Into E
