There’s no doubt in my mind that China is using coal and oil to bootstrap their renewable energy economy.
Energy availability and price determines the success of any economy. China are able to plan well ahead, and have realised that in 50 years (or sooner), whoever has the cheapest energy will be the world’s superpower. Renewable energy will be far far cheaper than oil and coal. Because energy costs will be so low for them, they will be able to produce goods more cheaply than anyone else.
China’s wind, solar and nuclear will dwarf everything else. I imagine they’ll pave the Gobi in solar panels, and why not? Electric vehicles everywhere, factories running at fractions of the cost of the “west”. Lots of workers, able to enjoy a good standard of living due to how cheap energy is resulting in a lower cost of living as all other prices are much cheaper.
In the meantime, yes, climate change is real. The climate always changing, but manmade emissions are making it change a lot faster (I have a degree in this stuff). The speed of change is the problem, as natural systems cannot adapt quickly enough. Add to that the fact that there are far too many people on the planet consuming energy and living in big cities near the coast, which means that large human movements become very difficult.
Were there, say, 1bn people on the planet the problem would be vastly reduced and energy consumption would be sustainable. As it is, the rapid modernisation of the populace brings with it far higher energy consumption per person, which increases the problem.
The best answer is small modular nuclear reactors everywhere, cover deserts in solar, and wind power around all the coastlines. The sooner the better.
