Wind energy

The most efficient technology to produce energy in a safe and environmentally sustainable manner: it is zero emissions, local, inexhaustible, competitive and it creates wealth and jobs.


Wind power is the energy obtained from the wind. It is one of the oldest energy sources exploited by humans and today is the most established and efficient renewable energy source. The academic term for wind power—eolic energy—is derived from the name of the Greek mythological figure, Aeolus, the keeper of the winds.



Wind power consists of converting the energy produced by the movement of wind turbine blades driven by the wind into electrical energy.



Wind energy is a source of renewable energy. It does not contaminate, it is inexhaustible and reduces the use of fossil fuels, which are the origin of greenhouse gasses that cause global warming.

In addition, wind energy is a “native” energy, because it is available practically everywhere on the plant, which contributes to reducing energy imports and to creating wealth and local employment.

For these reasons, producing electricity through wind energy and its efficient use contributes to sustainable development.

For these reasons, producing electricity through wind energy and its efficient use contributes to sustainable development.

Wind energy does not emit toxic substances or contaminants into the air, which can be very damaging to the environment and to human beings. Toxic substances can acidify land and water ecosystems, and corrode buildings. Air contaminants can trigger heart disease, cancer and respiratory diseases like asthma.

Wind energy does not generate waste or contaminate water—an extremely important factor given the scarcity of water. Unlike fossil fuels and nuclear power plants, wind energy has one of the lowest water-consumption footprints, which makes it a key for conserving hydrological resources.

Wind power is the most efficient technology to produce energy in a safe and environmentally sustainable manner: it is zero emissions, local, inexhaustible, competitive and it creates wealth and jobs.


wind power is expensive

Renewable energies are already the cheapest energy sources, and this will increasingly be the case. Wind power has advanced enormously from a technological viewpoint and their installation costs have lowered markedly. Over the past decade, the cost of onshore wind turbines has fallen by 37% and lithium batteries for storing electricity by 85%

Wind turbines are lethal for birds

The deaths of birds and bats by collision with wind turbines is much less than those produced by other human-led activities such as roads, railways, buildings or domestic cats, as well as those caused by the air pollution wind power helps to avoid.

Every renewable energies project must be accompanied by an environmental impact study before it can be approved by the competent authorities, which establish whether the site is compatible with the nature surrounding it, and corrective measures need to be adopted to minimize any harmful effects, e.g. monitoring and control by specialized teams, development of technological solutions such as repellents (ultrasound, noise and lights), detection and shutdown systems.

They rob land from agriculture and livestock

The surface area occupied by a wind turbine is minimal. In fact, wind farms are perfectly compatible with farming and livestock activities carried out on the same land. 

Manufacturing a wind turbine consumes more energy than the machine will be able to generate

A wind turbine offsets the energy used to make it in less than a year – and can function for over 30 years. Every wind turbine generates enough clean energy to cover the electrical demand from some 2,000 homes*. Moreover, the emissions produced by the manufacture and dismantling of a wind turbine represent around 1% of those it will avoid during its useful life in replacing production from coal, gas or fuel oil power stations, and this without counting the CO2 emitted during the building of those fossil fuel stations, nor the extraction or transport of fuel to those plants.


Wind turbines are very noisy

The noise produced by a moving wind turbine at a distance of less than 500 meters, within which there are rarely homes anyway, is no greater than that produced by an electrodomestic appliance such as a fridge or microwave. Wind farms also have to comply with local regulations with respect to noise levels during the day and night and cannot exceed the limits established by law.

Wind turbines are bad for human health

A renewable energies myth being spread in only a few countries. Independent public and private research has been conducted, however, and has concluded that there is no direct connection between wind farms and reported incidents of fainting or headaches.



According to the IEA (World Energy Outlook 2022), the share of wind energy in global electricity generation, which in 2021 was 7%, will quadruple that figure by mid-century, with a share of 28%, when all renewables will produce 80% of the world's electricity, only surpassed by solar photovoltaic at 31% as the main source of electricity generation.

Wind power accounts for approximately 80% of the electricity produced annually by the ACCIONA group. In 2022, the company produced a total of 18,876 gigawatt hours (GWh) from wind, equivalent to the consumption of around 5.52 million homes. By geographical area, 60% of wind power production was destined for the Spanish market, with 9,713 GWh, while 40% corresponded to other countries: Mexico (2,887 GWh), USA (2,067 GWh), Australia (1,075 GWh), Chile (817 GWh), Canada (524 GWh), India (354 GWh) and Portugal (276 GWh) as the main markets.


The world's installed wind power capacity at the end of 2022 exceeded 906GW installed capacity. According to estimates, it is expected that in 2023 the global wind power sector will reach the historic milestone of exceeding 1 TW (one million MW) of installed capacity in operation.

Spain has been one of the pioneers and leaders in harnessing wind to produce electricity. Thirty years after the first wind turbine was installed in the country, in 2013 Spain became the first country in the world in which wind energy was the main source of electricity generation for an entire year, which also places it as a very advanced country in technological solutions that allow its integration into the grid. In 2022, wind power generation accounted for around 22.1% of the total energy generated in Spain.

Spain is, with about 29,813 MW of installed wind power capacity in 2022, the second European country in terms of operational wind power capacity after Germany (67,006 MW), and the fifth in the world, after China (365,440 MW), the USA (144,226 MW) and India (41,930 MW),
