How to integrate significant volumes of non-hydroelectric variable renewables (that's wind and solar for the non-technical!) onto modern electricity grids? This question comes up time and again and this post by David Roberts at Vox is one of the best we have seen. It is clear, concise, well-balanced and eminently readable. We wanted to keep his article as a reference for all time - well at least for the next year or so. Hence the reason this blog consists of nothing more than a URL.  Enjoy,
