Germany shuts down its last three nuclear reactors

On 15 April 2023 Germany took its final three nuclear power plants - Isar 2, Emsland and Neckarwestheim 2 (about 4 GW combined) - offline, completing a decades-long, legally mandated nuclear phase-out after a brief energy-crisis extension. In the causal graph this event strengthens Renewable capacity buildout, a driver that strengthens Renewable share of global electricity generation — an improving welfare path.

On 15 April 2023 Germany took its final three nuclear power plants - Isar 2, Emsland and Neckarwestheim 2 (about 4 GW combined) - offline, completing a decades-long, legally mandated nuclear phase-out after a brief energy-crisis extension. The decision shifted reliance toward renewables and, in the short term, gas and coal.

    The government's coalition decision and the legal phase-out timetable directly caused the closures; it is a public, well-documented policy action in official capacity.

    Removing nuclear baseload increases the policy imperative and headroom for renewables in Germany, modestly reinforcing the buildout driver (though it also raised short-term fossil reliance).
