The Wind Fluctuates. Wind energy has a similar drawback to solar energy in that it is not constant. Although the wind is sustainable and will never run out, wind speed does change. This can cause serious problems for the efficiency of a wind ...
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.Dec 2, 2022 · Increased usage of wind energy has led to health benefits, but does not affect all communities equally, reports Saul Elbein for The Hill.The researchers found that in order to increase the benefits of wind energy, “the electricity industry would have to spin down the most polluting plants at times of high wind-supply — rather than their most expensive ones,” writes Elbein.
