What's needed to get sustainable energy for all (World Bank infographic)

The infographic above is pretty self-explanatory. What's interesting about it is that it provides very high level perspective on what remains to be done (though the title is a bit misleads; what the World Bank means by "Sustainable Energy 4 All" is actually no the end goal of sustainable energy for all, but the Bank's 2030 goals, a waypoint in that direction).
A high-resolution version of the infographic is available here.
