Sun energy in heat form is accesible for everyone. Oil require substantial investment.
Also keep in mind that all this is historical and that even replacing all people in bureacratic machine will make the dame machine to rwappear. E.g., government of energy/resource constrained country will be prwtty much same as previous. Orherwise many people will die.
If you can evict a person to streets at SF, you cannot do so anywhere in Russia. Rhere's not enough sun light. In China it is the same, except evicted person cannot use land, it is occupied.
As a russian/chinese government official you have to behave differently. You either will punish strongly to prevent bad behavioe, or you will prevent bad behaviour by other means.
And remember, if by some magic you made into chinese govt, you will start to behave more or less same as as current one. Just because gpvt reproduce themselves in same circumstances and for same goals.
We had very different governments in Germany in the last 200 years (Kleinstaaterei, Empire, Weimar Republic, Nazis, Communists, Social Democracy). Conditions didn't change that much in the last 100 years.
If yes, Russia has lots of oil, and China (and anyone else) can just build nuclear power plants. Problem solved.
