“won’t accept the difference”
Of course velocity is relative, and temperature has an absolute zero but in thermodynamics it’s differences in temperature that you deal with.
Now answer the questions I posed. Here are the first two:
Is electrical energy produced by the turbine?
Where does that energy come from?
Say as much as you want but make sure you answer the questions.
Yes electrical energy is produced by the transfer of momentum of the air to the rotational force on the turbine.
The only effects on temperature are the friction of the moving surfaces and the inefficiencies of the wind turbine equipment. Both of these produce heat.
There is no drop in temperature.
I have been referring to the energy in the moving mass as potential energy in relation to the still frame of reference of the windmill.
A better term is kinetic energy. Momentum is the mass times the velocity. Work is the mass times acceleration (deceleration of the wind mass). Kinetic energy is 1/2 the mass times the velocity squared.
When the wind strikes the turbine blades, the momentum of the collision must remain the same. In reality it is less of a collision and more of a sliding pull. But the result is a slight slowing of the air flow. Momentum is transferred from the air to the rotating blades. The slowing of the wind is a reduction of the air’s kinetic energy. This kinetic energy is the source electrical power transferred through the blades, rotor and generator. Each of those devices have some degree of inefficiency and each one generates heat due to the inefficiencies like friction.
There is no cooling, only heating and transfer of kinetic energy to electrical energy.
