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). 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.

It could come to shortages in the next winter, however it is possible to limit negative effects and alleviate social hardness by implementing the suggested counter-measures."
