Nuclear energy in the countries of the Three Seas Initiative under the new security architecture and climate policy

The article presents an analysis of the approach to nuclear energy and prospects for development in the countries that are members of the Three Seas Initiative. The author presents an analysis of the demographic and economic potential of the region in the context of a convergent history, conditioning the current infrastructural deficiencies compared to Western and Northern Europe. The paper employs a comparative analysis of the energy policies of the Initiative countries, concluding that the solution to the decarbonisation of the region is the development of nuclear energy potential and cooperation – due to its emission-free nature and guarantee of stable electricity production, together with the development of renewable energy sources. Such solutions guarantee significant progress towards decarbonisation and the achievement of international and EU climate targets, while ensuring energy security. The energy policy analysis is contextualised in the conditions of the new security architecture in Europe related to Russia’s war in Ukraine.
