How Wind Turbines Work
Transcript
Introduction
What Is Wind Energy Used For?
Wind energy is renewable and can make electricity which is generated directly from wind.
Wind energy is used for homes, buildings, hospitals, lights and technology, also wind turbines convert kinetic energy in wind into mechanical energy. This mechanical power can be used for specific tasks such as grinding grain or pumping water.
History
Although wind turbines didn't exist, a man named Professor James Blyth built the first ever windmill for electricity on july 1887 Glasgow, Scotland
and powered his home for 25 years.
In addition to this, people have harnessed the energy of the wind.
Wind energy propelled boats along the Nile River as early as 5000 B.C. by 200 B.C.

Finally this motion causes it to produce energy.
