I initially mentioned renewables as just one way to achieve CO2 emissions reductions. Nuclear is another way that works just as well. "we don't have a large-scale concrete example yet" China single-handedly added 230 GW of hydropower in 10 years (2006-2016). This could power the entire country of Japan (5th biggest electricity consumer in the world). If this isn't "large-scale" enough for you, I don't know what is ;) China also added a ton of fossil fuel power plants in that same period, but still it shows at least hydro, as a renewable, can work at very large scales.
