Which statement is correct about wind turbines?
A. They create mechanical and electrical energy.
B. They transform wind energy to electrical energy.
C. Their total energy decreases when electricity is produced.
D. Their total energy increases when electricity is produced.

The blades of the wind turbines are made to move by the blowing wind, thereby converting wind energy into mechanical energy. This movement of the blade in turn helps to generate electrical energy through an electromotive force.

The total energy remains conserved and only get converted from one form to another. Energy can neither be created nor be destroyed. The total energy neither increases nor decreases.

Which statement is correct about wind turbines? A. They create mechanical and electrical energy. B. They transform wind energy to electrical energy. C. Their total energy decreases when electricity is produced. D. Their total energy increases when electricity is produced.
