Until 2030, we do not expect any renaissance of nuclear energy use. Age-related decommissioning will rather result in a significant decrease of the number of reactors, installed capacity, and electricity generation in nuclear power plants. Until 2020, the number of nuclear power plants operating worldwide is expected to decrease by 22 %, until the year 2030 by approximately 29%, compared to the reference level in March 2009. This is the result of a study carried out by the Swiss Prognos Institut (PDF, 693 KB).
