Humans have been harnessing wind power for millennia, with windmills originally relying on wind to pump water or mill flour.
Today’s wind turbines work similarly, with their large blades generating electricity as wind causes them to rotate. As these blades are pushed by the wind, a connected internal shaft that is attached to an electric generator also turns and generates electricity.
Wind power is one of the safest sources of energy and relies on one key factor: wind speeds. When analyzing minimum wind speeds for economic viability in a given location, the following annual average wind speeds are needed:
Small wind turbines: Minimum of 4 meters per second (9 miles per hour)
Utility-scale wind turbines: Minimum of 5.8 meters per second (13 miles per hour)
