Old windmills wouldn't particularly store energy. For example they would only grind grain when the wind was blowing.
Or they would pump water into a tank when the wind was blowing.
Modern windmills generally generate electricity. For commercial windmills they are attached to the "Grid" which they treat somewhat as a battery. There still is risk of uneven power generation which would need to be evened out with either a storage method (some have suggested using battery powered automobiles as a "battery bank", or used with a complementary generation system that could be easily varied. For example hydro-electric may allow some diurnal variation in generation. It could still be a problem if there were many days of very high or very little wind.
Off grid systems are usually connected to some kind of a charge controller and then dumped into a battery bank. There is a risk of overcharging the batteries, and it is suggested to have some kind of a "dump load" such as an electric heater that can waste excess electricity without disconnecting the windmill from a "load device".

Do windmills store energy?
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.
What form of energy comes from windmills?
Wind energy is derived from windmills, which convert the kinetic energy of the wind into mechanical or electrical energy.
What energy is used in windmills?
Windmills use wind energy.
What energy can be found in moving objects such as wheels and windmills?
The energy of movement is called kinetic energy.
How are windmills powered-?
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.
Can windmills store energy?
Energy cannot be stored!

What form of energy comes from windmills?
Wind energy is derived from windmills, which convert the kinetic energy of the wind into mechanical or electrical energy.
Do windmills use kinetic energy?
Windmills transform the kinetic energy of the moving air mass into other energy forms.
What are windmills used for?
windmills are there to help save energy and renew electricity.
What energy is used in windmills?
Windmills use wind energy.
What energy transform in windmills?
Mechanical energy
How does windmills relate to energy and effects?
windmills spin causing movement and a mechanism harvests the movement and turns it into energy.
Why do you build windmills in the Netherlands?
They build windmills to generate 'clean and ecofriendly' energy.
What energy does windmills convert into electrical energy?
Kinetic

What are some uses of windmills?
for energy
