Energy Harnessed from the Wind: Part 2

Wind power generates electricity by transferring energy from wind to mechanical energy. The principle behind wind turbines is very simple: the energy in the wind turns two or three blades around a rotor. The rotor is connected to the shaft, which spins a generator to create electricity. Wind turbines are mounted on...

Energy Harnessed from the Wind: Part I

Imagine that something that you cannot see can have enough movement to harness energy! From a scientific perspective, air is like any other fluid -- if it can be moved forcefully, the motion provides kinetic energy. In a wind-electric turbine, the turbine blades capture the kinetic energy of the...
