WIND ENERGY

Today, wind energy is mainly used to generate electricity and the amount of electricity generated from wind has grown significantly in recent years. 

Like old fashioned windmills, today’s wind machines (also called wind turbines) use blades to collect the wind’s kinetic energy. The wind flows over the blades creating lift, like the effect on airplane wings, which causes them to turn. The blades are connected to a drive shaft that turns an electric generator to produce electricity.

Today’s wind machines are much more technologically advanced than those early windmills. But modern wind machines have still the problem of what to do when the wind isn’t blowing. To solve this problem, small turbines are sometimes connected to diesel/electric generators or sometimes have a battery to save the extra energy they collect when the wind is blowing hard.
