Abstract:

The world needs to continue working to protect the climate—this is generally undisputed. However, there is no agreement on which technologies should be used to decarbonize the energy sector. Many international scenarios still assume a relevant role for nuclear power in the future. However, a study by the German Institute for Economic Research shows that the Paris climate protection target— limiting global warming to below two degrees—can be achieved inexpensively without nuclear power. The results of a global energy system model indicate that no new nuclear power plants have to be built in order to meet the global climate target. It would be cheaper to use a combination of renewable energy and energy storage systems.
