The others deal with the technological possibilities of an energy transition to green energy and ask how it is practically and technologically possible to ensure energy security with green energy. Alternative technologies for energy production may play an important role in the energy transition. Without a transition to green energy, energy prices would not have had to rise so much, and energy security could have been better ensured by nuclear power plants. One deals with the economic and political aspects of the energy transition and energy security. [Extracted from the article]

Climate change, clean energy transition, the energy security quest, and international relations have triggered the revival of renewable energy as a solution to these problems. Nowadays, there is an energy transition where renewable energies bring geopolitical changes in a world where fossil fuels are becoming less relevant. This article aims to assess how the transition influences Spain's energy relations with other countries regarding electricity and its sources, in alignment with the European Green Deal. In order to do so, its current energy situation, the renewable energies development and its energy import-export relations are examined. The results show that despite progress in green regionalization through more electric interconnection, little difference is to be found in traditional relations with fossil fuel countries exporters, but more are the contractions in Spanish energy economic policy, as here is explained.
