Wind energy could meet up to a fifth of global electricity demand by 2030, according to a major report released yesterday by the Global Wind Energy Council (GWEC) and Greenpeace International.

The report, which looks at a number of different scenarios for the development of the industry and projected levels of electricity demand, predicts installed capacity could increase more than four-fold from 240GW at the end of last year to 1,100GW by 2020, supplying between 11.7 per cent and 12.6 per cent of global electricity, and saving nearly 1.7 billion tons of CO2 emissions.

Under less ambitious scenarios, the group predicts total capacity would reach between 587GW and 759GW, providing up to 8.3 per cent of global electricity supply.
