Electrical Energy from Wind

If you live in a place where the wind blows consistently, then wind power makes sense.

Large turbines are grouped together to form wind farms that contribute electricity to the national grid.

The wind turns a large blade, which turns an electrical generator.  The motion energy from the wind creates electrical energy.

Wind turbines cannot create electricity if there is no wind or there is too much wind.  In heavy wind storms, the turbine is stopped from moving by a brake, otherwise the heavy winds would damage the turbine.

Wind farms are both environmentally good and environmentally bad.

They are good because they reduce the need for fossil fuels or nuclear power.

They are bad because they kill migrating birds, create a lot of noise and many people do not like how they look.

 

An eyesore?  Or a necessary evil?
Wind farms are often considered ugly.
