David McKay's estimate of onshore wind energy

This is an extract from McKay's book Sustainable Energy Without The Hot Air

Potential energy from onshore wind in the UK can be calculated by multiplying the average power per unit of land area covered by a wind farm by the area per person (population density) thus arriving at the power available per person from wind.

Assuming the wind speed is 6 metres per second (13 miles per hour or 22 km/h), the power per unit area of a wind farm is 2W per square metre. In reality the figure of 6 metres per second is probably an over estimate for many locations in Britain, Cambridge only recorded such a figure on about 30 occasions during the course of 2006.

The population density is about 250 people per square kilometre which is 4000 square meters per person. Therefore wind could generate (assuming the 6 metres per second figure for wind speed) 8000 W per person.

This is assuming that wind turbines stretched across the entire country.

If you convert that figure to the commonly used unit for power …
