Horizontal axis wind turbine (HAWTs) are the most common wind turbines used. Consisting of one to three blades that spin around a rotor, these turbines look like giant propellers jutting from the landscape atop an aerodynamic tower on a hillside. Wind passes through the blades, affecting the pressure on either side. This pressure creates a lift force that causes the blades to rotate around the rotor. The rotor converts the power of the wind into usable energy. Both cost effective and efficient, these turbines harness the power of the winds that blow several meters above the ground.
