I'll talk about whichever country i like, and Germany is a perfect example of how NOT to do it. Although UK comes close second.
As for 'old' articles, physical laws of nature don't change at all, so it's valid whenever. But here is a recent article to please you:
Germany’s Wind Performance Was Just As Bad As Great Britain’s – Sun And Wind Are Often AWOL http://notrickszone.com/2013/03/04/germanys-wind-performance-was-just-as-bad-as-great-britains-sun-and-wind-are-often-awol/
And facts are just facts, no matter who tells them. And the facts are very clear, variable energy is not a realistic option for any nation. That is why for example Japan just recommenced building a new nuclear reactor instead of a wind/solar whatever system
I guess they have less ecological hysterics to deal with. I rather not wait 20-30 years to find out the nation suffers all the time from blackouts and prices rise through the roof once the subsidies dry up.
