Wind Power: Pros and Cons of Wind Power For Agriculture

Wind mills, wind pumps, and wind turbines all convert kinetic energy into mechanical energy for different uses. Common ways that wind power is used in agriculture is to charge batteries, grind grain, and even pump water. Our ancient ancestors used wind in much the same way, though obviously wind turbine technology has come a long way.

How Do Wind Turbines Work? | Department of Energy

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.
