According to the Global Wind Energy Outlook released by the Global Wind Energy Council (GWEC) and Greenpeace, global wind power capacity could reach 2,000 MW by 2030 (advanced scenario), supplying up to 17-19% of total power generation and reducing CO2 emissions by more than 3 Gt/year. Wind power could contribute by 25% to 30% to the global power supply by 2050.
Total wind power capacity in 2013 reached 318 GW and about 45 GW should be installed in 2014. Under the moderate scenario, installed wind capacity worldwide should total 712 GW in 2020 and 1,480 GW in 2030. In 2030, China should account for 28% of the global capacity, followed by OECD Europe (23%), OECD North America (20%), India (8%) and Latin America (6%). In this scenario, annual investment in wind power will increase to €80bn by 2020 and to €102bn per year by 2030.
This is in line with the estimations provided in Enerdata's EnerFuture service. The Emergence scenario, the most optimistic scenario in terms of renewables, plans a wind installed capacity of 2,200 MW in 2030 whereas the business as usual scenario plans around 1,300 MW of installed capacities.
