14 November 2012 (Global Wind Energy Council)
“…[The fourth Greenpeace International and the Global Wind Energy Council] bi-annual report on the future of the wind industry…shows that wind power could supply up to 12% of global electricity by 2020, creating 1.4 million new jobs and reducing CO2 emissions by more than 1.5 billion tons per year, more than 5 times today’s level. By 2030, wind power could provide more than 20% of global electricity supply.”
The Global Wind Energy Outlook paints a picture of three…scenarios out to 2020, 2030, and eventually to 2050; and then measures these scenarios against two different projections for the development of electricity demand: the first based on the International Energy Agency’s World Energy Outlook, and another, more energy efficient future developed by the ECOFYS consultancy and researchers at the University of Utrecht…”

Wind power is by definition an indigenous energy source, which is particularly useful to countries burdened with large fossil fuel import bills; and wind power is now competitive in an increasing number of markets, even when competing against heavily subsidised ‘conventional’ energy sources, with little or no financial compensation for its environmental and social benefits: zero CO2 emissions, zero water use, and no air or water pollution…” “Wind energy installations totalled 240 GW globally by the end of 2011, and the industry is set to grow by at least another 40 GW in 2012. By 2020, the IEA’s New Policies Scenario suggests that total capacity would reach 587 GW, supplying about 6% of global electricity; but the GWEO Moderate scenario suggests that this could reach 759 GW, supplying 7.7-8.3% of global electricity supply. The Advanced scenario suggests that with the right policy support wind power could reach more than 1,100 GW by 2020, supplying between 11.7-12.6% of global electricity…”
