The global energy crisis has become an issue that dominates international discourse in recent years. With increasing energy demand, price fluctuations, and the impact of climate change, the world is facing major challenges that are significantly influencing global politics. One of the main causes of this crisis is the dependence of many countries on fossil energy sources. Oil and natural gas, which provide energy for most industries, face challenges from declining reserves, geopolitical tensions and efforts to shift to renewable energy. Tensions in the Middle East region, for example, have caused oil prices to spike, exacerbating economic instability in many countries. Countries rich in energy resources, such as Russia and Saudi Arabia, play an important role in global geopolitics. They can use their energy wealth as a diplomatic tool or, conversely, a weapon to create pressure on other countries. When these countries reduce energy supplies, the impacts are felt, from inflation to social crises. The global energy crisis has also triggered a shift in geopolitical alliance patterns. Countries with access to renewable energy, such as Norway and Denmark, are increasingly taking center stage. In addition, countries that do not yet have sufficient energy resources must carry out international cooperation to achieve energy security. This leads to multilateral energy agreements that could change relations between countries. As technology develops, several developing countries are trying to utilize renewable energy sources to reduce dependence on fossil energy. Investments in solar, wind and bioproducts are now an important part of the national strategy. However, this shift has not always been smooth; corruption, weak infrastructure and lack of funding are the main obstacles. The impact of the energy crisis is also visible in countries’ domestic policies. Countries in Europe, for example, have prioritized developing green energy policies to reduce carbon emissions. International meetings such as COP26 reflect global awareness of the importance of collaboration in tackling climate change. The energy crisis is also driving innovation in energy storage technology and efficiency. Companies are now competing to find better and cheaper solutions. This creates new opportunities in the market, but also presents challenges for industries based on traditional energy. Due to this shift, several developed countries see opportunities to strengthen their position in the global energy market. Investments in developing countries are key to securing energy supplies in the future. However, this can also lead to exploitation and social injustice. Government actions and international collaboration must be closely monitored, remembering that the impact of the energy crisis can spread to various sectors, from the economy to national security. Discourses on energy justice and accessibility are also increasingly important in this context, driving the need to listen to the voices of marginalized communities. The shift that occurred as a result of the global energy crisis brings opportunities as well as complex challenges. Strengthening cross-country cooperation in technological innovation and energy policy could be key to facing this challenge. Sustainable energy security will depend largely on how countries adapt to rapid and often unpredictable global change.
