Which average wind speed do areas need to effectively power wind farms?

A:1 mph

B:5 mph

C:10 mph

D:16 mph

Generally, annual average wind speeds greater than four meters per second (m/s) (9 mph) are required for small wind electric turbines (less wind is required for water-pumping operations). Utility-scale wind power plants require minimum average wind speeds of 6 m/s (13 mph).

The average wind speed required to produce power at a wind farm is 16 m. p. h.
