When a windmill turns to generate electricity,the amount of kinetic energy input in the process___________ .

Question

Quizplus · Accepted Answer

The amount of kinetic energy input in the windmill is proportional to the wind speed and the surface area of the rotor blades. However, not all of this kinetic energy can be converted into electrical energy due to losses in the conversion process. These losses include friction in the mechanical components of the wind turbine, resistance in the electrical wiring, and other inefficiencies. Therefore, the amount of electrical energy produced is always less than the amount of kinetic energy input, making option C the correct choice.
