The most ambitious scenario by the Global Wind Energy Council (GWEC) show that,
with growth rates much lower than the 30% the wind sector has experienced over the past decade,
global wind energy capacity could increase from 121GW at the end of 2008 to over 1,000GW by 2020 and 2,400 GW by 2030.
This would result in annual CO2 savings of more than 1.5 billion tons in 2020 and 3.2 billon tons in 2030.
