here are some wind turbines working together to create electricity.
how wind turbines work
Wind turbines are used to generate electricity out of wind. As such they need wind to create wind and if they don't have wind they don't make electricity. But wind turbines can hurt our health if you stay near them for too long you start to get a headache.

How wind power is used efficiently
Harnessing the power of the wind has become one of the fastest growing sources of global electricity generation. One of the key features of wind energy is the fact that it is free and will never run out. Even though it's a completely renewable energy resource, wind is not available all the time harnessing the power of the wind has become one of the fastest growing sources of global electricity generation. Today’s wind turbines are much more efficient than the windmills of the past. They have fewer blades but as wind speeds increase, the amount of electricity generated increases.
