The war in Ukraine is sparking a wide-ranging revamping of energy policy in Europe with a bold new objective: to wean the continent off Russian gas – as rapidly and comprehensively as possible – and accelerate Europe's green energy transition. Now, European leaders are pushing for a faster switch to renewables as part of a strategy to end dependence on Russian gas. Their ambitious plans now call for fast-tracking deployment of solar and tripling clean energy capacity by 2030. In the article "Will Russia's War Spur Europe to Move on Green Energy?" by Paul Hockenos, R. Andreas Kraemer and Sascha Müller-Kraenner, both founders of Ecologic Institute, explain the opportunities and possible paths for an accelerated energy transition and independence from Russian gas.
