Wind energy is available virtually everywhere on Earth, but there are wide variations in wind strength and consistency. One estimate suggests that there is 1 million GW of wind energy available from the total land coverage of the Earth, and if only 1% of this land was utilised at achievable efficiencies this would meet global electricity demand. Although most wind energy is currently obtained onshore, offshore wind farms are becoming more popular as a larger resource area with low environmental impact (particularly considering noise and visual pollution).

The United States of America have the largest wind energy installed capacity, at over 25 GW, but Denmark has the highest capacity per capita at 3 GW, 20% of the total electricity production. In 2009, global wind energy capacity reached 120 GW, with 72 GW located within the European Union. Behind the USA, Germany and Spain have the highest wind energy capacities in place.

A site is considered ideal for wind energy production if there are winds of over 6.9 m/s at a height of 80 m above ground.
