Many words could describe wind energy and green jobs. “Sustainable” is not one of them - Boone Pickens, Nacel Energy, Vestas Iberia and others have been issuing statements and running ads, extolling the virtues of wind as an affordable, sustainable energy resource. Renewable energy reality is slowly taking hold, however.
Spain did increase its installed wind power capacity to 10% of its total electricity, although actual energy output is 10-30% of this, or 1-3% of total electricity, because the wind is intermittent and unreliable. However, Spain spent $3.7 billion on the program in 2007 alone, King Juan Carlos University economics professor Gabriel Calzada determined.
