Wind Energy

What wind speed do I need to operate a small/micro wind turbine?

In general, most small/micro wind turbines start to generate electricity at wind speeds of 3-4 metres per second (m/s), or 7-9 miles per hour. Most small/micro wind turbines achieve their rated output at wind speeds of 10-12 m/s or 22-27 mph. Therefore the greater the wind speed the better.

From the data above there is no possibility of any useful wind generated electricity at this site in Harrow.
