      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

          What was the rational explanation for closing the recently refurbished Nuclear fleet in Germany ahead of the filthy lignite plants. The German Nuke fleet was superbly maintained and had they closed lignite earlier than Nukes we would have seen significant CO2 Emission reduction

          and a part of the problem is in how renewables are positioned in the energy & climate discourse: see e.g. Harjanne, A.; Korhonen, J.M. (2019) Abandoning the concept of renewable energy, Energy Policy, Volume 127, April 2019, Pages 330-340. https://doi.org/10.1016/j.enpol.2018.12.029 …

          Unfortunately Germany was too hasty in closing down nuclear power. So despite impressive increase in renewables' share in power & heat production (congrats for that), German (energy sector) CO2 emissions didn't drop much in the past 10 years.

          Look at the flat earth worshipping LNP, the earth didn't blow up and guess what, they did it because they care about our earth, not because they're the largest polluters or the smallest

          How much is the decrease of CO2 if I may ask?
