If there is too little wind and the blades are moving too slowly, the wind turbine no longer produces electricity. The turbine starts to create power at what is known as the cut-in speed. Why is that? The answer lies in aerodynamic design, mechanical engineering, and power system integration. Let's explore the science and. . How can windmills create electricity if they're so often moving slowly? The short answer is that if they move slowly, they produce less power.
