Nana · Answer 1

If the blades of a windmill are spinning, then the whole assembly

has mechanical (kinetic) energy.

If they were made to spin by a battery and a motor inside, then

the kinetic energy of the blades came from electrical energy, and

they're passing their kinetic energy to air in order to move it.

If they were made to spin by wind blowing past the blades, then

they robbed some of the kinetic energy from the moving air, and

that can be used to turn a generator inside and convert the kinetic

energy into electrical energy.

Electrical, but it only produces a little bit of electrical.
