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.
It''s Fun Fact Friday and today we''re going to take a look at energy storage. Power demands fluctuate throughout the 24 hour cycle, creating the need for adjustments in supply.
