Too much of a good thing? Spain's green energy can exceed demand

Operated by Spanish firm Iberdrola, they are part of a trend that has accelerated Spain’s renewable energy output over the past half-decade, making the country a major presence in the industry.
Spain’s total wind generation capacity, its prime renewable source in recent years, has doubled since 2008. Solar energy capacity, meanwhile, has increased by a factor of eight over the same period.
This makes Spain the EU member state with the second-largest renewable energy infrastructure, after Sweden in first place.
