Wind Speed Wind can be used to generate electricity. Wind can be used to generate electricity. Before that power can be harnessed to generate electricity, wind speed has to be determined. Before that power can be harnessed to generate electricity, wind speed has to be determined. If the speed is not fast enough to generate electricity, then it may not be an ideal location for a wind turbine. If the speed is not fast enough to generate electricity, then it may not be an ideal location for a wind turbine.

Wind Turbine Wind turbines are machines that convert the wind energy (kinetic) into electrical energy. Wind turbines are machines that convert the wind energy (kinetic) into electrical energy. Wind is a completely renewable resource for generating electrical power. Wind is a completely renewable resource for generating electrical power. On average, the wind needs to On average, the wind needs to supply a constant wind speed supply a constant wind speed of 22.5 km per hour for the of 22.5 km per hour for the turbine to generate electricity. turbine to generate electricity.

Measuring Wind Speed Wind speed is measured using a tool called an anemometer. Wind speed is measured using a tool called an anemometer. The anemometer records the The anemometer records the number of revolutions per number of revolutions per unit of time and then converts unit of time and then converts it into miles per hour or it into miles per hour or kilometers per hour. kilometers per hour. http://www.smg.gov.mo/www/dm/equip/ws.jpg

The formula to calculate speed is: Speed = distance time v = d t
