The global energy crisis has had a significant impact on international relations. In recent years, fluctuations in energy prices, especially oil and gas, have impacted the foreign policies and diplomatic strategies of countries around the world. First of all, dependence on fossil energy means that certain countries are forced to form alliances based on energy needs. For example, oil producing countries that are members of OPEC often collaborate to regulate oil supplies and prices. This not only creates market dynamics, but also strengthens their political position on the international stage. Meanwhile, countries that depend on energy imports try to secure supplies, often by establishing diplomatic relations and military cooperation with energy producing countries. Second, energy crises often exacerbate regional tensions. Countries involved in regional conflicts, such as those in the Middle East, see energy resources as a tool to strengthen their position. Competition for control of energy transit routes or strategic energy storage carries deep political implications. For example, tensions between Russia and Ukraine have focused on the control and supply of natural gas, impacting the rest of Europe. When Russia reduced gas supplies to Europe, European Union countries had to rush to find alternatives, including strengthening cooperation with other energy producing countries such as Qatar and the US. Third, the development of renewable energy is starting to change the face of international relations. Countries that invest in green technologies, such as solar and wind, are trying to strengthen their position in the global market. Countries such as China and Germany are becoming leaders in the renewable energy industry, beating old traditions based on fossil energy. This green energy diplomacy is creating new alliances that may not be based on natural resources, but based on technology and sustainability. For example, cooperation between Scandinavian countries in clean technologies is becoming a model for international cooperation. Furthermore, changes in energy policy could trigger migration and social instability. Energy-starved countries often experience economic crises leading to an increase in the number of refugees. This is a challenge for receiving countries which must accommodate and integrate migrants. Therefore, the energy issue is not only an economic problem, but also a humanitarian problem that needs to be addressed in foreign policy. The influence of the energy crisis is also visible in the arena of multilateral diplomacy, such as the COP or climate meetings. Developed and developing countries are experiencing push-backs in emissions and energy use policies, creating tensions in negotiations. Commitments to reduce dependence on fossil energy often clash with immediate economic needs, especially in countries that still depend on traditional energy resources. Finally, shifts in energy policy touch on security aspects. Some countries are taking steps to protect their energy assets and resources, creating tensions. For example, the rise of militarism in the South China Sea is closely linked to control of the region’s rich energy resources. Countries with the potential for conflict must address these challenges through careful diplomacy and comprehensive security strategies. With all these elements, it is clear that the energy crisis will not only impact the global economic system, but also interconnected international relations. Countries must innovate in their approaches to energy to ensure political stability and global security in the future.
