Wind Energy

Anything that moves has kinetic energy, and scientists and engineers are using the wind''s kinetic energy to generate electricity.

How a Wind Turbine works

Wind turbines work on a very simple principle: the wind turns the blades, which causes the axis to rotate, which is attached to a generator, which produces DC electricity, which is then converted to AC via an inverter that can then be passed on to power your home. The stronger the wind, the more electricity is generated from the motion.

Wind Energy: How A Wind Turbine Works

Wind energy causes the turbine''s blades to rotate, turning a set of gears attached to the generator. The wind''s energy is subsequently transformed into electricity via the generator. Even light breezes can generate power because the longer the blades, the more kinetic energy they can "harvest" from the wind.

Wind explained Electricity generation from wind

How wind turbines work. Wind turbines use blades to collect the wind''s kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn.
