Table 1

Installed wind power per country (units in GW) of some of the biggest world producers from 2005 to 2012. The growing rates (with respect to the preceding year) corresponding to 2011 and 2012 have been also added in brackets to illustrate the present status of the wind energy market (sources: Global Wind Energy Council; US Energy Information Administration).
