    Germany made it! Over 40% renewable electricity* in 2018, for the first time ever. After 38.2% in 2017, now 40.4%. Nuclear 13.3%, fossils 46.3% *) based on net power generation for the public grid. Thx Bruno @energy_charts for your data and charts!pic.twitter.com/yPn9U1Wnwd

        In 15 years, the share of renewables in German electricity quintupled, from 8.5% in 2003 to 40.4% in 2018. Since just before its nuclear exit (2010), it gained 21%-points.pic.twitter.com/ZpJcjMG0xG

        That meant that renewables were able to replace the electricity from the nuclear power plants shut down since 2011 (Fukushima), and reduce electricity from gas (-35%) and hard coal (-25%) at the same time. Lignite (brown coal) use remained stable, due to its low marginal cost.pic.twitter.com/IctG9CWBzR

        Germany’s coal exit is mainly about its exit from lignite, which is domestically produced. Some energy companies and trade unions lobby to go slowly, while climate action requires a fast exit. The Coal Commission is supposed to come up with a plan in the coming few months.

        The share of renewable electricity varies from week to week. The lowest weekly share was 26% in week 42 (Oct), and the highest was 53.5% in week 49 (Dec). So making it work at even higher shares is not just about day/night storage (batteries), but also about bridging those weekspic.twitter.com/a3y51VCY3d

        Imagine where Germany would be if they restarted their nuclear power plants ..... So much further advanced and costing a lot less money.

        They won’t. And even under the pre-Fukushima lifetime extension plan, the exit would have started by 2022.

        What about a little bet? $1 says Germany will have > 1GW nuclear power in production on June 30, 2023. That is after the planned shutdown. Japan restarted reactors this year. German emissions will rise significantly with every shutdown, as brown coal is extremely dirty.

        I don’t think so (and Japan always said it wants to restarts its nuclear power plants, temporarily closed after Fukushima). It could well be that the Coal Commission will soon announce a first lignite power plant shutdown before that date too.

        So great to hear except biomass burning is not renewable and contributes to climate change. Especially if it came from wood pellets from forests.

        Most of it is biogas. Very little wood pellets from forests in German electricity.

        No, would be nice to add, Bruno @energy-charts! Must be decreasing slightly over the years, as the share of fossil electricity goes down.

        Not so much, no. The decision to eliminate nuclear energy has essentially resulted in replacing one low-carbon source with another. Had they kept nuclear energy at baseline, emissions would be down sharply.pic.twitter.com/15WhEzrtp1

        We should not just look at the face value that the emissions remained constant. Consider population growth and economic growth, growth of either means increase in energy consumption but with No increase in emissions I consider it a success

        I think the binary of success/failure of the Energiewende encourages people to get into their defensive crouches rather than appreciating what we can learn from it. 1) We can increase renewables in the electricity mix. 2) That is not the same as reducing fossil fuel burning.

        3) Nuclear power produces A LOT of low-carbon electricity, and if your conception of a "Green New Deal" (to borrow a phrase from a different polis) includes eliminating nuclear energy, you are going to be running in place for some time re CO2 emissions.
