Energy cannot be stored!
Windmills themselves do not store energy. However, some wind energy systems incorporate energy storage technologies such as batteries or flywheels to store excess energy generated by the windmills for use when the wind isn't blowing.
Wind energy is derived from windmills, which convert the kinetic energy of the wind into mechanical or electrical energy.
Windmills transform the kinetic energy of the moving air mass into other energy forms.
Windmills use wind energy.
windmills are there to help save energy and renew electricity.
Mechanical energy
windmills spin causing movement and a mechanism harvests the movement and turns it into energy.
They build windmills to generate 'clean and ecofriendly' energy.
Kinetic
err....yea.... windmills use wind, clue is in the title
for energy
A windmill runs off of the energy that the wind provides. The wind blows against the blades of the windmill and turns them, causing them to turn a turbine. This turbine converts wind energy to kinetic energy, something that we can store and harness.
