Best Answer

In any machine some energy is always lost as heat. In a wind turbine most of this will be created by friction between parts.

How efficient are wind turbines?

They are not very effecient. a wind turbine that is 50 % effecient is very effecient compared to other wind turbines. this is because most of the kinetic energy is changed into heat instead of electrical energy.

How do you get wind energy and how is wind energy obtained?

Wind energy is obtained by placing wind turbines in high-wind areas. The rotation of the turbine spins multiple large gears which power a generator, which in turn generates 100% green energy.
