France emits 90% less CO2/kWh than Germany (they didn't even need renewables to achieve that, just nuclear): http://environmentalprogress.org/big-news/2017/2/11/german-electricity-was-nearly-10-times-dirtier-than-frances-in-2016 http://environmentalprogress.org/big-news/2017/2/11/german-e...
And according to https://www.hsdl.org/?abstract&did=801297 https://www.hsdl.org/?abstract&did=801297 CO2 emissions per kWh have already decreased 2.58%/year between 2005 and 2016 (-25% over 11 years). That's already far better than the 1.60%/year I assumed (-80% over 100 years), further strengthening my point that these Nature authors' assumption that CO2/kWh will never improve in 100 years is utterly unrealistic.
- mrpopo 8y agoIn the US, that was mostly due to gas replacing coal. France is not using renewables. This is great, but not due to renewables as you initially claimed. Also, I don't think the share of bitcoin mining is significant in these examples. I was asking for a country that managed to reduce their CO2 emissions significantly with renewables. It may happen in the future, and I'm certainly hoping for it, but we don't have a large-scale concrete example yet.
- mrb 8y agoI 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.
