The kinetic energy (energy of movement) of wind throughout the world is about more than 11 quadrillion kilowatt-hours per year.
A kilowatt-hour is the amount of work done by 1,000 watts in one hour.

Egyptians used wind-powered sailing ships as early as 2800 B.C
By the 12th century, inventors discovered that windmills produced more power if the sails or blades turned on a horizontal shaft
Most early windmills used this rotational energy to operate machinery to grind grain

Most windmills have a rotor of blades or sails that are turned by the wind.
Wind turbines have two or three blades but some have more.]]> 2018-02-23 21:49:10 UTC https://padlet.com/bellman641/ppbusvq0xwak/wish/234921311 Pros bellman641 https://padlet.com/bellman641/ppbusvq0xwak/wish/235026843 We can get this energy anywhere wind.

The shaft is turned by the movement of the rotor, and it transmits power, through a series of gears, to a vertical shaft. The shaft then transmits power to a water pump, flour mill, electric generator, or other device]]> 2018-02-24 21:53:01 UTC https://padlet.com/bellman641/ppbusvq0xwak/wish/235028080 Renewable or non-renewable bellman641 https://padlet.com/bellman641/ppbusvq0xwak/wish/235030740 Wind power is renewable]]> 2018-02-24 22:29:02 UTC https://padlet.com/bellman641/ppbusvq0xwak/wish/235030740 bellman641 https://padlet.com/bellman641/ppbusvq0xwak/wish/235632612 2018-02-26 20:59:42 UTC https://padlet.com/bellman641/ppbusvq0xwak/wish/235632612 bellman641 https://padlet.com/bellman641/ppbusvq0xwak/wish/236163526 2018-02-27 21:07:01 UTC https://padlet.com/bellman641/ppbusvq0xwak/wish/236163526 bellman641 https://padlet.com/bellman641/ppbusvq0xwak/wish/236163824 2018-02-27 21:07:44 UTC https://padlet.com/bellman641/ppbusvq0xwak/wish/236163824 bellman641 https://padlet.com/bellman641/ppbusvq0xwak/wish/236170112 2018-02-27 21:23:11 UTC https://padlet.com/bellman641/ppbusvq0xwak/wish/236170112 Sources bellman641 https://padlet.com/bellman641/ppbusvq0xwak/wish/236170812 World Book Student
