sentences:  The Global Wind Energy Council (GWEC) predicts that wind energy will supply 15.7% of the world's total energy needs by the year 2020, and 28.5% by the year 2030.This dramatic increase in global wind energy generation will require installation of a newer and larger fleet of more efficient wind turbines and the consequent decommissioning of aging ones.Based on a study carried out by the European Wind Energy Association, in the year 2010 alone, between 110 and 140 kilotons of composites were consumed by the wind turbine industry for manufacturing blades.
