Qatar came to mind when I read about natural gas. Remember when Sheikh Mohammed al-Thani, the foreign minister, announced it would boost liquefied natural gas (LNG) in the face of sanctions by Gulf Arab States + Egypt (2017)?
At USD $124,100 that year, Qatar has one of the highest GDP per capita in the world. That oil (gas) money won't last though. I used to say that about Saudi Arabia.
Unless it diversifies its exports, Qatar's major markets will be developing nations without the economic agility (I think Rifkin used that term) to phase out fossil fuel and nuclear energy consumption.
