WHAT IS WIND ENERGY?
Air has mass and when it is in motion, it causes kinetic energy which can be transformed into electricity.

IS WIND ENERGY DIFFERENT FROM OTHER RENEWABLE ENERGIES?
The technological maturity of wind energy means that the economic cost differential with regard to conventional technologies is small. This means that the tariffs paid for wind are lower than those of other renewable technologies (except for mini-hydraulic plants). However, it is not only an economic issue; the Spanish wind sector is an industrial “cluster”: in Spain we have everything from the companies that make the screws to those that manage the wind farms in real time with world leading computer systems, as well as the wind generator manufacturers. A value chain which entails 0.30% of Spanish GDP (2020 data) spread amongst 16 regions. In Spain we don’t have any oil fields, but we can regard the wind turbines which are spread throughout Spanish territory serve as our “clean energy wells”.
WHAT PERCENTAGE OF ELECTRICITY DEMAND DOES WIND ENERGY COVER?
In 2021, wind power has been the main source of electricity generation in Spain with more than 23% of production, thus leading the national generation mix for the first time since 2013. Wind power will be one of the technologies that has increased its production the most compared to 2020, in addition to being the first technology in installed power of the system. In 2020, wind power covered 21.9% of demand, positioning itself for another year as the second source of electricity generation. Definitely, it was the renewable with the greatest presence in the generation structure of the Spanish electricity system. In 2019, wind power covered 20.8% of the peninsular electricity demand, being the third technology in the Spanish electricity system. In 2018 it covered 19% being the second technology. In 2017, wind power returned as the second technology in the Spanish electricity system, covering 18% of the electricity demand in the peninsula.In 2016, wind energy covered 19.3% of the electrical demand in the peninsula and it was the second source of the Spanish electrical system. In 2015 wind energy was the third source of electricity in a whole year with a demand coverage of 19%. In 2014 it was the second source with 20.3% and in 2013 the first when covered 21% of the electrical demand.
HOW LONG DOES IT TAKE TO INSTALL A WIND FARM?
WHY DOES ELECTRICITY PRICES DECREASE WHEN THE WIND BLOWS?
Wind energy has in its DNA the decrease of electricity price in Spain and in many other countries. The more wind energy that enters the energy system, the more the price decreases, as it displaces more expensive technologies. Therefore, the greater the proportion of wind energy consumed, the less Spaniards pay on their electricity bill. And viceversa.

WITH THE EMERGENCE OF CHINA AND THE US, ALONG WITH OTHER COUNTRIES, IN WIND ENERGY, WHAT ROLE WILL THE SPANISH WIND ENERGY SECTOR PLAY IN THIS NEW WORLD SCENARIO?
WHAT ARE THE ENVIRONMENTAL BENEFITS COMPARED WITH FOSSIL FUELS?
The technologies which burn fossil fuels generate greenhouse gases which contaminate, exacerbate climate change and affect health and the environment. Wind energy does not generate emissions as its fuel is the strength of the wind: wind energy avoids the emission of 28.7 million tonnes of CO2 and avoids imports of fossil fuels by 1,389 million euros.
