Key Issues For Future Of Wind Energy In Spain
September 10, 2009
The journal Energy Policy has recently reported two studies that highlight some key issues for the future of wind energy in Spain. A team of engineers from the University of Zaragoza believes it is “technically viable and economically reasonable” for wind energy to account for 30% of Spain’s overall energy production. A report by two researchers from the University of Alcalá (UAH) and the European Wind Energy Association (EWEA), meanwhile, says the number of jobs generated by this sector in the European Union has increased by 226% since 2003.
“Nowadays, wind farms supply around 12% of the electric energy produced in Spain, but by 2030 this could rise to 30%”, says José Luis Bernal, of the Department of Electric Engineering of the University of Zaragoza and co-author of a study published recently in the journal Energy Policy.
His team has developed its own calculation method based on the amounts of energy contributed by various sources. The results show that an energy mix, with wind energy providing 30%, solar energy 20% and gas turbines a further 20% (10%-15% biogas and 5%-10% natural gas), is technically and economically viable in Spain.
