22% of the energy Spain used in August 2009 came from renewable resources

That's the title of an article here in Spanish. The numbers come from the WWF (World Wildlife Fund) in its most recent Observatorio de la Electricidad. The WWF is of the opinion though that it will be difficult for Spain to pass the 40% threshold, so if they wish to pass 50% by 2020 then it will require working in all areas of renewable energy, not just wind power or any other method alone.

There are quite a few more numbers in the article so instead of referencing them here either read the article in Spanish above or automatically translated into English here.
