power coefficient

The power coefficient is a measure used to evaluate how efficiently a wind turbine converts the available wind energy into electricity. It compares the actual power generated by the turbine to the maximum possible power available in the wind at that location and wind speed. A higher power coefficient indicates a more efficient turbine, meaning it captures a larger share of the wind’s energy. Typically expressed as a percentage or a decimal, it helps engineers optimize turbine design and placement to produce more energy with less waste.
