The global energy crisis has become a very important issue in recent decades, creating increasing tensions between countries. Changes in extreme weather conditions, depletion of natural resources, and geopolitical conflicts have triggered a spike in energy prices, which has had a significant impact on the world economy. One of the main factors contributing to this crisis is the ever-increasing demand for energy, especially in developing countries. Population growth and urbanization make energy consumption soar. Countries such as India and China are struggling to meet energy needs, further exacerbating global competition. This encourages energy producing countries to tighten export policies and review their international agreements. Damage to the supply chain due to the COVID-19 pandemic has also made the situation worse. In an effort to rehabilitate their economies, many countries are accelerating the development of new energy infrastructure, sometimes ignoring sustainability aspects. This guidance creates fears of resource conflicts and civil war in several regions. On the other hand, the rise of renewable energy makes competition even tighter. Countries rich in renewable resources, such as wind and solar, are becoming important actors, fueling tensions with countries dependent on fossil energy. For example, European countries are seeking to reduce dependence on Russian natural gas, forcing Moscow to seek new alliances in Asia. Instability in the Middle East, which is the center of global oil production, is also exacerbating the crisis. Prolonged conflicts such as those in Yemen and Syria are often related to the control of energy resources. Countries in this region are victims of political tensions and power competition, which often involve large powers from outside the region. Increasingly stringent environmental regulations also play a role in complicating energy markets. Carbon emission reduction policies implemented in many countries require energy companies to adapt quickly, which is sometimes inconsistent with their capacity. This creates resistance from traditional sectors, prolonging tensions between countries. Governments face pressure to provide affordable energy to their citizens. It is in this context that many countries are looking for short-term solutions to overcome price spikes, although this often results in political tensions both domestic and international. Unequal allocation of resources only increases the gap between rich and poor countries. Recent reports show that countries that invest in renewable energy research and innovation reap greater benefits in terms of energy security and sustainability. All of this shows that a global energy future requires collaboration, long-term strategies and innovative thinking. Energy diplomacy tactics are now increasingly necessary. Countries must find ways to build mutually beneficial relationships while addressing the challenges they face. With tensions continuing to increase, international cooperation in managing energy resources is vital to maintaining global stability.
