If the new renewable energy sources were really as good as advertised - not only cleaner than fossil fuels, but also so much cheaper as well - then this would indeed be both obvious and inevitable. China in particular has a lot of the world's capacity to produce renewable generation equipment, they shouldn't need to rerun the pollution of western countries to have prosperity and this would solve both their massive pollution problems and their need to find new infrastructure projects to fund in order to prop up the economy, both major political headaches domestically. Yet they keep on pointing to the West's emissions as justification for why they should increase CO2 output instead. They also don't have the NIMBY problems of some Western countries. My general conclusion is that the reason for this is that switching to green energy is neither as easy nor as cheap as advertised. Sure, on paper the cost per GWh is great and you can even realise much of that for the first few projects, but the cost of dealing with a lack of dispatchability and of intermittency from sources like solar and wind ends up massively outweighing that in practice. So no-one actually wants to switch to an all-renewable grid.
