worldwide wind power production is very predictable, with annual variations remaining within a ± 3 % range
wind energy indexes that Eoltech releases each month for the 300 geographical areas worldwide with the highest number of farms
Global Index covers geographical areas which host about 80% of the world’s operating onshore wind farms as of 2023, while the European Index cover 97% of the continent’s operating wind farms
European Index shows that wind resource annual variations are within a ± 7% range in Europe, compared to ± 3% worldwide
Locally, the production of a wind farm can differ significantly from one year to another, up to 25%, due to the variation of the wind resource
our analysis does not show any downward trend over the last 15 years in the global wind resource
wind does always blow somewhere on the planet
