Question

If a wind turbine extracted 100% of the kinetic energy out of the wind, what would happen?.

Answer 1

all of the wind would have to stop completely upon contact with the turbine

Step-by-step explanation:

Wind turbines work by slowing down passing wind in order to extract energy. If a wind turbine was 100% efficient, then all of the wind would have to stop completely upon contact with the turbine—which isn't possible by looking at a wind turbine.
