This is actually my preferred measure too. I was happy to use GDP PPP figures because they tell a similar story to the energy statistics on ourworldindata.org. Asia miles ahead, China the most dominant, then the US and then EU. India looking to overtake the EU fairly rapidly if they follow China's footsteps.
Of course the per-capita numbers favour the US still. But by absolute figures, the crown goes to Asia. And per capita the Europeans can realistically be said to be behind China for policy making purposes, the trends are clear.
