The current global energy crisis is a complex challenge that significantly affects international relations. Factors such as climate change, dependence on fossil energy sources, and geopolitical instability, contribute to an increasingly stressful situation. Countries around the world are forced to find solutions to this energy problem, which has an impact on international diplomacy and cooperation. Renewable energy sources are the main focus of global energy discussions. Many countries, such as Germany and Japan, have invested heavily in green energy technologies to reduce dependence on oil and gas from traditional energy producing countries. This step not only focuses on environmental sustainability but also on increasing national energy security. The move towards renewable energy has sparked new international partnerships, creating a platform for technologically advanced countries to share innovation and experience. On the other hand, large energy consuming countries such as China and India, which still depend heavily on coal, are struggling to achieve a balance between industrial development and the environment. They face pressure from the international community to reduce carbon emissions while meeting growing energy demand. Initiatives such as the Paris Agreement put energy and climate change issues at the top of the diplomatic agenda, with countries competing for excellence in clean energy innovation and investment. The energy crisis also creates new dynamics in the region by generating new tensions between energy producing countries and importing countries. When energy prices soar, there is a risk of increased conflict, either directly or through economic sanctions. For example, tensions between Russia and Western countries following the invasion of Ukraine exacerbated Europe’s dependence on Russian gas, prompting Europe to look for alternatives, such as LNG from the United States. The influence of the global energy crisis on international security is very visible in the Middle East region. Oil-producing countries, including Saudi Arabia and Iran, are experiencing a changing balance of power. International sanctions against Iran reduced the country’s ability to export oil, causing the country to strengthen alliances with non-Western countries as a strategic response. In the context of Southeast Asia, energy stability is a determining factor for multilateral cooperation. Countries such as Indonesia and Malaysia, which have significant energy reserves, play an important role in energy market dynamics. The ASEAN+ meeting discussing energy cooperation emphasized the importance of energy integration, sharing access and technology in achieving collective energy security. Then, the role of technology in the energy crisis cannot be ignored. Innovations in energy storage, efficiency and smart energy grids are now gaining traction in international diplomacy. Collaboration between technology companies and governments accelerates the transition to more sustainable energy solutions. The global energy crisis is not only an urgent problem at the domestic level, but also affects geopolitics at large. Competition for energy resources must be managed wisely through international dialogue and cooperation. Through understanding and collaboration, countries can find solutions that benefit all parties, reducing tensions while building a more sustainable and energy stable future.
