Hey John, the graphic is more a comment on how little energy have in some countries. Hence the closing sentence: 'Improving energy access is one of the great challenges of our time.' Although only Qatar and Norway exceed the US on per capita residential electricity use.
As for the unique position of the US poor in regards to energy access, you'll need some stats for that. By any measure the US has far greater poverty, and in some cases fuel poverty, than large swathes of the OECD. And while the EU typically taxes electricity in the range of 5-50% compared to hardly any in the US, the fact the EU has expensive electricity is as much a function of being dependent on imported fuels for power generation. Electricity prices in the UK are now double the US, only 5% is tax
I still find the graph a useful reminder of how much energy the world needs to develop further in the future.
