Our Finite World: "what happens to world CO2 emissions when we ramp up intermittent renewables? As far as I can tell, it tends to raise CO2 emissions. One way this happens is by ramping up China’s economy, through the additional business it generates in the making of wind turbines, solar panels, and the mining of rare earth minerals used in these devices. The benefit China gets from its renewable sales is leveraged several times, as it allows the country to build new homes, roads, and schools, and businesses to service the new manufacturing. In China, the vast majority of manufacturing is with coal."
