Wind Energy

This is the second part in a SaveOnEnergy series discussing the ins and outs of different forms of renewable energy. Harnessing the power of the wind is not a new idea. In fact, humans have been using wind power for hundreds of years. From filling the sails of massive ships to the classic windmills powering grain mills, wind power has...

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...

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...
