Although Austria is surrounded by land and is really hilly topography, meteorological preconditions permit the utilization of wind power. First calculations on the basis of wind measuring data assessed at the meteorological stations in the early 1980s rendered the surprising result of annually approx. 6,600 to 10,000 gigawatt-hour (GWh) of technically exploitable wind energy potential in Austria. [1]
Austria ranked as the world's seventeenth largest producer of wind power with an installed nameplate capacity of 995 megawatt (MW) in 2008, behind Ireland and ahead of Greece. [2]
Back in the 1980s, there were huge private wind measurements and experiments with smaller plants. In 1994, initiated by Councilor Waltner, 110 kilowatt (kW) wind turbine was set up in St. Pölten. Another wind turbine was put into operation six months later in Zistersdorf. In 1995, the first wind turbine was built with civic participation in Michelbach.
In January 1996, the first turbine of the type E-40 with 500 kW was placed in Eberschwang. Not only the absolute largest wind turbines were placed there, but with two plants the first „wind farm“ was established. In the course of 1996, no signs of new funding arrangements had emerged. It led by the end of the year in a panic reaction from the first „boom“ for wind power.
36 wind turbines with 12 MW and an annual total of 18 million kW of work hours had been set up between New Year's Day and New Year's Eve. [3] After 1996, there were, only in exceptional cases, economic conditions for individual projects, including the wind park in Zurndorf with six plants.
The pressure of individual countries and the idea that desired objectives could be reached nationwide cheaper than by any nation-state alone resulted into negotiations between federal and state governments to a new nationwide Green Electricity Act 2002 (Ökostromgesetz 2002) in spring 2002.
Wind turbines with a capacity of a total of 276 MW were built in 2003. The plant output tripled from 139 MW (end 2002) to 415 MW (end 2003) within a year. [3]
According to manufacturers, the life span of wind turbines amounts to 25 years. [4] Important influences on the life span are site specific (wind speed, storms, icing conditions) and the quality of the maintenance of the turbines.
External costs are not a part of the investment and operation costs, and are paid by the tax payer and therefore by the public. Examples of external costs for fossil fuel and nuclear electricity production are political and military securing of the access to these energy sources, costs of green house gas emissions, cleaning up of spilled oil, police operations during the transporting of nuclear wastes and other similar activities. Negative external costs arise from wind turbines' impact on landscape aesthetics, animal habitats, increased mortality of bats and birds, noise, and flickering. However, wind power also has positive external effects on power system operation and through the mitigation of air pollution. The hidden costs of wind power in Austria are currently not quantified.
Most of the property owners are farmers. They have an additional source of income by leasing their land to the wind park operator. The prices paid for property leases for wind turbines are many times more than would normally be earned by farming the property.
A wind turbine needs an area of up to 500 square metres (5,382 square feet) and the rest of the property can still be farmed without any problem. [4] A wind turbine can also be easily and quickly dismantled.
According to the costs for infrastructure, a kW of installed capacity costs between €880 and €1,487 (Windpark Handalm). (At the Tauernwindpark a kW costs €1,240 ). [4]
The table shows an annual increase in installed wind power capacity from 2000 to date.

Production of wind power does not release any pollutants. A wind park with 6 MW installed capacity will reduce approximately the following emissions yearly: [8]
| Carbon dioxide | 13,600,000 kg |
| Sulphur dioxide | 20,720 kg |
| Nitrogen oxide | 10,220 kg |
| Carbon monoxide | 8,550 kg |
| Dust | 560 kg |
| Nuclear wastes | 72 kg |
Wind power is a form of renewable energy in Pakistan which makes up more than 6% of the total electricity production in the country. As of 2018, wind power capacity in Pakistan was 1,287 MW. The government is looking to increase the share of renewable energy and plans to add around 3.5 GW of wind energy capacity by 2018.
Spain is one of the countries with the largest wind power capacity installed, with over 27 GW in 2020. In 2013 it had became the first country in the world to have wind power as its main source of energy.
Wind power generation capacity in India has significantly increased in recent years. As of 31 December 2023, the total installed wind power capacity was 44.736 gigawatts (GW), the fourth largest installed wind power capacity in the world. Wind power capacity is mainly spread across the southern, western, and northwestern states.
Wind power' is a major source of energy in Portugal. At the end of 2020, wind power capacity in Continental Portugal was 5,456 MW. In 2020, wind power represented 23.7% of total electricity generation.
Wind power in Ohio has a long history, and as of 2016, Ohio has 545 megawatts (MW) of utility-scale wind power installations installed, responsible for 1.1% of in-state electricity generated. Over 1000 MW more were under construction or pending approval. Some installations have become tourist attractions. There has been a sudden increase in generating capacity, as the total wind power capacity in the state was just 9.7 MW in 2010. By 2019, there were 738 MW of capacity, which generated 1.71% of Ohio's electricity.
China is the world leader in wind power generation, with the largest installed capacity of any nation and continued rapid growth in new wind facilities.

Windmills have historically played a major part in the Netherlands by providing an alternative to water driven mills.

Repowering is the process of replacing older power stations with newer ones that either have a greater nameplate capacity or more efficiency which results in a net increase of power generated. Repowering can happen in several different ways. It can be as small as switching out and replacing a boiler, to as large as replacing the entire system to create a more powerful system entirely. There are many upsides to repowering.
The great majority of wind turbines around the world belong to individuals or corporations who use them to generate electric power or to perform mechanical work. As such, wind turbines are primarily designed to be working devices. However, the large size and height above surroundings of modern industrial wind turbines, combined with their moving rotors, often makes them among the most conspicuous objects in their areas. A few localities have exploited the attention-getting nature of wind turbines by placing them on public display, either with visitor centers on their bases, or with viewing areas farther away. The wind turbines themselves are generally of conventional horizontal-axis, three-bladed design, and generate power to feed electrical grids, but they also serve the unconventional roles of technology demonstration, public relations, and education.
