Wind and hydro-power make up almost 50% of Spain's 2013 usage

 "Over the last couple of years, Spain has embarked on a massive program to increase it's renewable energy production, radically increasing its fleet of wind mills and solar panels. Now that program is bearing some serious fruit.

Red Eléctrica de España, Spain's electricity grid operator, has released a preliminary report announcing that in 2013 the single largest source of power in Spain was wind.

Meeting a total 21.1% of the nation's electricity demand, wind farms outshone nation's nuclear reactors which provided a mere 21%. 
 
Moreover, when combined with solar and hydroelectric power, renewables were able to provide a total of 49.1% of Spain's total electricity output, an impressive feat when you consider the United States only draws a bare 12% from renewable sources. All this reliance on renewable energy has, in turn, allowed the nation to decrease the carbon output of its energy sector by 23.1% in a single year."
