Growth of Clean Energy Part of Solution, Not a Problem

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.

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 energy currently supplies over 3 % of global electricity consumption and this is expected to exceed 5 % by 2020. In the longer term (by 2040), the International Energy Agency forecasts that wind energy could meet 9 % of global electricity demand and more than 20 % of demand in Europe.

Wind power makes up approximately 80 % of the electricity produced by ACCIONA annually. In 2014, the company produced a total of 17,482 gigawatt hours (GWh) from the wind, equivalent to the consumption of around five million people. In terms of geographical spread, 60 % of this wind energy, or 10,378 Gwh, was produced for the Spanish market, while 40 % was produced for other countries: the USA (2,278 GWh), Mexico (2,174 GWh), Australia (932 GWh), Canada (516 GWh), Portugal (417 GWh), Italy (239 GWh) and India (226 Gwh) were the other main markets.


By the end of 2015, wind power capacity totalled 400,000 MW in the world, according to provisional estimates by consulting firm Navigant/BTM, which forecasted that this would increase by over 40% by 2019, to exceed 600,000 MW.
