How does wind energy work when there is no wind?
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. Power output continues to grow as the wind speed increases, but at a slower rate than it does right after the cut-in point.
What happens to wind energy when there is no wind?
Much of the energy can be simply sold back to the utility company and used immediately on the power grid. With power lines running all across entire continents, if there is too much power locally, it can always be sold to far off places.
