Der Aktionsplan f\u00fcr das 1,5-Grad-Szenario listet ambitionierte Ma\u00dfnahmen auf. Beispielsweise m\u00fcssen ab dem Jahr 2030 weltweit j\u00e4hrlich \u00fcber 1.000 GW Wind- und Photovoltaikleistung installiert werden.<\/p>\n<p>Als anschauliches Beispiel f\u00fchrt der Bericht aus, dass daf\u00fcr rein rechnerisch ein globaler Photovoltaik-Ausbau in der Gr\u00f6\u00dfenordnung des weltgr\u00f6\u00dften Solarparks pro Tag erforderlich w\u00e4re \u2013 und zwar ab sofort. Nach Berechnungen der IEA sollen erneuerbare Energien bis 2050 mit einem Anteil von rund 70 Prozent die wichtigste Energiequelle werden. Nur etwa 20 Prozent der fossilen Brennstoffe wie Gas k\u00f6nnten noch genutzt werden, wenn man dies durch die Abscheidung und Nutzung von Kohlendioxid kompensieren w\u00fcrde. Bis 2030 m\u00fcssten die weltweiten Investitionen in saubere Energien gem\u00e4\u00df der Net Zero-Roadmap der IEA auf rund 4 Billionen US-Dollar pro Jahr erh\u00f6ht werden.<\/p>\n<p>Vollst\u00e4ndiger IEA-Bericht: https:\/\/www.iea.org\/reports\/net-zero-by-2050, zuletzt aufgerufen am 11.11.2021 um 9:25 Uhr.<\/p>\n<p>Quelle:<\/p>\n<p>pv-magazine (10\/21-21): <a href=\"https:\/\/www.pv-magazine.de\/2021\/10\/21\/iea-net-zero-2050-plan-fuer-cop-26-photovoltaik-und-windkraft-werden-weltgroesste-energiequellen\/\">https:\/\/www.pv-magazine.de\/2021\/10\/21\/iea-net-zero-2050-plan-fuer-cop-26-photovoltaik-und-windkraft-werden-weltgroesste-energiequellen\/<\/a>,\u00a0last access 11\/11\/2021 at 9:15 am.<\/p>","protected":false},"excerpt":{"rendered":"<p>The International Energy Agency&#8217;s (IEA) World Energy Outlook (WEO) was all about the big picture this year: ahead of the start of the COP26 global climate conference in Glasgow, the IEA presented its &#8220;Net Zero 2050 Roadmap&#8221; on how net emissions can be reduced to zero by 2050 so that the agreed 1.5-degree target is [&hellip;]<\/p>","protected":false},"author":1,"featured_media":1881,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[26],"tags":[],"class_list":["post-1880","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v24.0 -
