This graphics-laden presentation reviews Europe's natural gas relationship with Russia, and the challenges & practicalities involved in dissolving the gas bridge between East & West built over the past 2 generations. The unintended consequences of de-russification will have worldwide impact. I review Europe's demand, uses, and supply sources of natural gas as well as the various LNG producers & pipeline networks supplying Europe - and the steep challenges of replacing Russian natural gas over the short to medium term. This presentation was given via Zoom on behalf of The Continuing Education Center of Rancho Bernardo, CA on March 8, 2022.
