How should nations that sit on top of large coal reserves and lack any other fuels work without energy source? Not everyone has enough money to build nuclear plant or enough wind for wind power plants, or enough high water for water power plants, or enough sun for solar plant. More over, why do you want coal plants to be disabled now? Developed countries used it for many years, until they got richer and have the luxury of choosing how they will get power. You want undeveloped countries to use more pricey power source from the start? This will slow down their development (in comparison to the first round of countries).
