More Wind Power, Renewables Needed to Fight Climate Change, Experts Warn Lisa Bryant MARANCHON, SPAIN -- The air was bone chilling on a recent afternoon, as blades from dozens of wind turbines lining the ridge cut through a milky sky. Not so long ago, Maranchon was Spain's largest wind farm, its 104 machines capable of powering a mid-size city. But today it faces competition, testament to wind energy's surging growth here and elsewhere. While Spain's wind industry has had a rocky decade, it still remains Europe's second biggest wind producer after Germany, and a leading exporter of wind technology. And as governments continue climate talks in Madrid, experts say wind and other renewable energy sources will be crucial to fight the escalating rise of greenhouse gasses--yet their massive potential remains untapped. .
