Wind Energy
Wind energy is power we capture from moving air, often by spinning blades that turn a generator.
Think of it this way
A pinwheel sitting in a bowl spins when air moves across its flat blades. The faster the air moves, the faster the blades spin. A wind turbine works the same way — moving air pushes large flat blades, and that spinning motion powers a generator.
Explaining wind energy by grade level
Wind pushes on things and makes them move. When wind hits a blade on a windmill, the blade spins. That spinning motion can make power, just like a battery does. Bigger blades catch more wind, so they spin with more force.
