The global energy crisis is currently a major concern throughout the world. The main causes of this problem are increasing energy demand, decreasing resource supply, and growing geopolitical tensions. Many countries depend on supplies of fossil fuels, so price fluctuations can cause diplomatic tensions. In this context, conflicts in energy-rich regions, such as the Middle East and Russia, trigger tensions between countries. For example, international sanctions against Russia due to the invasion of Ukraine created concerns about the continuity of gas supplies to Europe. European countries are trying to find alternatives, including the development of renewable energy and increasing cooperation with other energy producing countries, such as the United States and Qatar. Renewable energy sources, such as wind and solar, are growing in popularity, but the transition requires time and significant investment. Many countries have invested in green technologies, but dependence on fossil fuels remains high, causing tensions between energy-rich countries and those seeking to accelerate the energy transition. In this situation, energy producing countries, such as Saudi Arabia and Russia, tend to maintain their market dominance. Tensions may increase not only because of competition for supply, but also because of climate change. Commitments to reduce carbon emissions have caused countries to try to reduce dependence on fossil energy. However, this has the potential to end existing bilateral relations, creating friction in the international arena. In this scenario, global energy markets serve as an arena in which great powers compete for access to dwindling resources. Countries need strategies to protect their energy supplies, which sometimes leads to aggressive military or diplomatic action. Changes in domestic energy policy also have global impacts. Countries that place a high value on renewable energy can create tensions with oil-producing countries trying to maintain prices. Rapid energy transitions can sometimes be interpreted as a threat, thereby triggering a negative response. Overall, the global energy crisis changed the pattern of international interactions, where energy power became a good bargaining tool in negotiations. Countries around the world must adapt to this new reality, where energy stability depends not only on production but also on cooperation between countries. The challenges faced in the framework of international cooperation and tensions between countries show how complex global energy issues are. All parties must commit to finding more harmonious ways to share resources, while taking into account domestic needs and environmental responsibilities. This energy crisis is not just about prices; it is a reflection of a wider range of issues: foreign policy, security and sustainability. The only way to achieve stability is to integrate multilateral approaches, transparency and innovation in the global energy sector.
