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).

World wind power generation capacity has reached 435 GW at the end of 2015, around 7% of total global power generation capacity. Global wind power generation amounted to 950 TWh in 2015, nearly 4% of total global power generation.

The wind power market can be divided into large wind onshore (422 GW, around 210,000 machines), small wind onshore (less than 1 GW installed end 2015, more than 800,000 machines), and offshore (around 12 GW installed end 2015, around 4,000 machines). Large onshore and offshore wind turbines are typically arranged in a wind park. The largest wind parks exceed 1 GW in size, such as Gansu Wind Farm in China, Muppandal Wind Park in India or Alta Wind Energy Center in USA.

China has the largest wind energy installed capacity with 145 GW, followed by the United States with 73 GW, Germany 45 GW, India 25 GW, Spain 23 GW and the UK 14 GW.

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.

Wind data on installed capacity (MW) and annual output (GWh) is sourced from the International Renewable Energy Agency (2016) and represents values at the end of year 2015.
