Wind power is the conversion of winds kinetic energy into useful forms of energy, such as: using wind turbines to make electricity, windmills for mechanical power, windpumps for water pumping or drainage, or sails to propel ships.
To generate electricity wind turbines rely on large blades being spun by the wind. The shape pf the blade is such that the air pressure beneath it increases and the air pressure above it decreases. This causes the blades to rotate which turns a shaft within the turbine that moves magnets in a generator, thereby creating electricity. The amount of electricity created by the wind turbine depends on both the wind speed and air density, which are impacted by temperature, air pressure and the altitude of the farm.
Capturing the wind for local power generation has been around since the 1930s. Before large-scale electricity supply was available in rural areas, more than 600,000 windmills were used to produce electricity and pump water on farms across Canada and the United States.
