How Wind Works Home wind turbines are simple machines with only a few moving parts. The wind turns the blades which turn the shaft which drive the generator, creating electricity. Turbine systems generally include
Wind power, like most sources of energy on earth, originates from the sun. As the earth orbits the sun daily, it receives light and heat. The majority of the heat from the sun is received at the equator and it gradually reduces towards both poles. The following figures illustrate that the temperature of the earth varies depending on conditions at that specific location. Across the earth these heat differences help create wind. In warmer regions of the earth the air is hot and is therefore at a high pressure, compared with in colder regions, where the air is at a low pressure. Wind is the movement of air from areas of high pressure to low pressure. This movement is complicated by several other factors that means wind does not always flow from the equator in the direction of either pole. The rotation of the earth creates a force known as the Coriolis force and this factor along with the temperature differences create winds at high altitudes above the earth on a large scale.
