The use of wind energy slow downs climate change and complies with international commitments
In attempts to curb climate change, 196 countries reached a historic agreement in December 2015. In the so-called "Paris Agreement", the States pledged to put all the necessary means to limit global warming to two degrees above pre-industrial era (trying not to even exceed 1.5 degrees), since scientists warn that exceeding this limit would have catastrophic consequences for humanity.
A drastic reduction of greenhouse gas emissions is necessary in order to achieve the objectives of the Paris Agreement. In the current scenario, and taking into account the individual objectives of each State (the so-called “nationally determined contributions" or NDC, its acronym in English), temperatures could rise to a range between 2.6-3.2 degrees¹ at the end of this century and therefore, well above the target set in Paris.

Thus, one of the most effective ways to reduce greenhouse gas emissions is the progressive substitution of fossil fuels by renewable energies, and in particular, by wind energy. The implementation of wind energy is flexible, fast and inexpensive, making it key in achieving international objectives. According to IRENA (the International Renewable Energy Agency), renewable energy, together with greater energy efficiency, could reduce in 90% the CO2 emissions needed to meet the Paris objectives. In this case, wind and photovoltaic solar would have to increase production to jointly represent 52% of the electricity production in 2050 (currently 5.5%).
In 2017, wind was the second technology system in our country (only behind the nuclear one) and it prevented the emission of 28 million tons of CO2, according to data from the Spanish Wind Association (AEE). It is estimated that without wind, the emissions from the electricity sector would have been 35% greater.
