Should new nuclear power plants be banned and existing plants closed after 45 years?

AI-generated summary, admin reviewed: This initiative proposed banning new nuclear power plants and limiting existing plants to 45 years of operation. The three oldest plants would have had to close within one year, and the final plant would have closed by 2029. It also directed energy policy towards lower consumption, greater efficiency and renewable sources. Supporters argued that fixed closure dates would reduce accident risks and accelerate the energy transition. Opponents said the country had already decided to phase out nuclear power without fixed dates and warned of shortages, costs and compensation claims. Swiss voters rejected the initiative.
