Can renewable provide 100% of grid power reliably?

I think that we all knew that this would work, there are loads of renewable energies to combine. None the less there is a lot of skepticism on this issue to it's great to see an example of this in opperation. Good work Germany!

Scientists of the University of Kassel in Germany prove that the entire country can be powered by renewables only. They connected biogas, wind and solar power in a distributed way and show it can deliver both baseloads and peakloads.
