May 30, 2012. Spanish renewable-energy companies that once got Europe's biggest subsidies are deserting the nation after the government shut off aid, pushing project developers and equipment-makers to work abroad or perish. From wind-turbine maker Gamesa Corp. Tecnologica SA to solar park developer T-Solar Global SA, companies are locked out of their home market for new business. These are the same suppliers that spearheaded more than $69 billion of wind and solar projects since 2004 that supply more than 50 percent of Spain's power demand on the most breezy and sunny days.
