Wind Energy Per 3

Wind Energy is the process by which wind is used to generate electricity. Wind turbines convert the kinetic energy in the wind into mechanical power

• True

• False

The more dense the air, the more energy received by the turbine.

• True

• False

turbines will produce more power at higher elevations

• True

• False

Turbines will produce more power in locations with cooler average temperatures.

• True

• False

The energy in the wind turns two or three propeller-like blades around a rotor. The rotor is connected to the main shaft, which spins a generator to create electricity.
