Feasibility

TL;DR: Russian energy embargo is feasible both technically and economically, and popular counter-arguments do not stack up

Economical studies

Numerous studies by different research institutes and think tanks show that immediate embargo of Russian gas, oil and coal would be manageable. The costs are estimated comparable or below Coronavirus protection measures (e.g, -0.5% to -6% GDP in Germany). A moderate recession of -2 % to -3 % in 2023 would be followed by a quick recovery in 2024. Importantly, most studies analyzed the impact of an embargo starting from March/April 2022. Banning Russian energy now (May/June) would be even easier/cheaper: EU gas storage filling levels increased from 25% in March to 50% as of June, 5th . Cynically, this "improvement" was paid by thousands of Ukrainian lives.

Bundesnetzagentur	21.06.2022	Germany	Natural gas	Gas-Mengengerüst von 06/22 bis 06/23	No gas shortage in scenarios without Nord Stream 1, but with proportional export reductions and/or 20% savings (since 07/2022) and 16 GW of LNG (since 01/2023). Small to moderate shortage (19-107 TWh) in other scenarios. There seems to be an underestimation of the savings impact in scenario 2.2.1 https://www.bundesnetzagentur.de/DE/Fachthemen/ElektrizitaetundGas/Versorgungssicherheit/aktuelle_gasversorgung/HintergrundFAQ/Gas-Mengengeruest.pdf;jsessionid=2E00AAA3FF302C0BD29E07D9A52C8909?__blob=publicationFile&v=3#page=5, which should be higher if we assume the graphically about 20 GWh/h savings as of https://www.bundesnetzagentur.de/DE/Fachthemen/ElektrizitaetundGas/Versorgungssicherheit/aktuelle_gasversorgung/HintergrundFAQ/Gas-Mengengeruest.pdf;jsessionid=2E00AAA3FF302C0BD29E07D9A52C8909?__blob=publicationFile&v=3#page=6 for scenario 2.2.1.

IWH Halle update	20.06.2022	Germany	Natural gas	Deutsche Gasspeicher erreichen jahreszeitüblichen Füllstand.	Gas reserves are sufficiently filled so that immediate embargo is manageable. Some shortage expected in case of very cold winter. "Seit [der Vorgängerstudie im April] hat sich die Situation jedoch deutlich verändert. Die Füllstände der deutschen Gasspeicher entsprechen mittlerweile dem für die Jahreszeit üblichen Niveau von etwa 50%, und sie dürften noch weiter steigen. Sollte es im Laufe der kommenden Monate zu einem Lieferstopp für russisches Gas kommen, könnte der Gasbedarf im Winter 2022/2023 wohl vollständig bedient werden zumal höhere Gaspreise die Nachfrage dämpfen wüden. Bei einem sehr harten Winter mit entsprechend hohem Gasverbrauch in den privaten Haushalten könnte es allerdings immer noch zu einem Engpass kommen."

Bruegel	28.02.2022	Europe	Natural gas	Preparing for the first winter without Russian gas	If all Russian gas imports were to stop on March 1, 2022: "Europe would need to reduce demand by at minimum 400 TWh (or 10%-15% of annual demand). This is possible. A portfolio of exceptional options could abate at least 800 TWh."

Opinions and statements

It is important to differentiate between evidence- and data-based studies listed above, and individual opinions, which are based on general wisdom and/or (presumed) expertise in the field, and can be heavily biased.

Pro-embargo

• Prof. Veronika Grimm, Wirtschaftsweise: „Es gibt kein Modell, das eine Katastrophe plausibel darlegt“
• Prof. Reint Gropp, Präsident des Leibniz-Instituts für Wirtschaftsforschung Halle: "Gleichzeitig ist unstrittig, dass die Ukraine nicht nur sich selbst, sondern das gesamte westliche Wertesystem und unser Modell einer freiheitlichen Gesellschaftsordnung verteidigt. Da scheinen ein paar Prozent weniger Wachstum, gerade auch wenn der Staat bei den niedrigen Einkommen unterstützend eingreift, zu verschmerzen zu sein. Einige Beobachter, insbesondere aus der Industrie, haben aber argumentiert, dass speziell ein Gasembargo [...] im Winter zu frierenden Menschen und dem Abschalten ganzer Industriezweige führen würde. Ich denke, dass man diese Aussagen als von Eigeninteresse getriebene Schreckgespenste abtun kann. Denn es bleibt dabei unklar, warum eine Kombination von Wiederhochfahren der Kohle- und wohl auch Atomkraftwerke in Verbindung mit einem forcierten Ausbau der erneuerbaren Energien sowie Energieeinsparungen (die sich durch die höheren Preise von selbst einstellen würden) und Flüssiggasimporten das Problem nicht lösen sollten. Es bleiben natürlich Risiken, aber ich denke, unsere Freiheit sollte es uns wert sein, jetzt konsequent zu handeln"
