Les USA viennent de franchir le seuil des 50 GW de puissance éolienne installée !

U.S. wind energy reaches 50 gigawatts – AWEA

....
Utility-scale wind power generation began as early as the 1980’s, although it took 23 years to reach 5 GW of generating capacity from 1981 to 2003. Capacity then reached 10 GW in 2006, 25 GW in 2008, and now doubling that this year.

“The last time a new energy technology ramped up to 50 GW was nuclear, in the late 1970’s and early 1980s – since then, no new energy technology has been as successful as wind,” the association said.

World wind capacity reaches 197 GW

11 April 2011

Worldwide wind capacity has reached 197 GW despite a slight decrease in new capacity, according to the World Wind Energy Report 2010 from the World Wind Energy Association (WWEA).

Just over 37.6 GW of wind were added in 2010, slightly less than in 2009. With a growth rate of 23.6%, wind has seen the slowest growth since 2004.

Nevertheless, wind now has the capacity to generate 430 TWh annually – equalling around 2.5% of global electricity consumption.

The wind power sector had a turnover of €40 billion and employed 670,000 worldwide in 2010.

Chinese lead
China has become number one in total installed wind capacity and the centre of the international wind industry, adding 18,928 MW within one year, accounting for more than 50% of the world market for new wind turbines.

A major decrease in new installations was observed in North America and the USA lost its number one position in total wind capacity to China. At the same time, many Western European countries are showing stagnation, whereas there is strong growth in a number of Eastern European countries.

Germany keeps its number one position in Europe with 27,215 MW, followed by Spain with 20,676 MW of wind power.

The highest shares of wind power can be found in three European countries: Denmark (21%), Portugal (18%) and Spain 16%). Whereas Asia accounted for the largest share of new installations (54.6%), followed by Europe (27%) and North America (16.7%).

Latin America (1.2%) and Africa (0.4%) still played only a marginal role in new wind power installations.

Finally, WWEA says a global capacity of 600 GW is possible by the year 2015 and more than 1.5 TW by the year 2020.
