The global energy crisis is currently one of the most profound issues in geopolitics. The impact on global stability is increasingly felt, especially amidst increasing tensions between energy producing countries and consumers. The crisis was triggered by a combination of factors, including growing demand, regional conflict, and a shift toward renewable energy. Energy producing countries such as Russia, Saudi Arabia and the United States have an important role in influencing world energy prices. Political tensions, especially involving Russia and Ukraine, have led to sanctions impacting gas and oil supplies. This is unsettling global energy markets, increasing fuel prices and disrupting supply chains. In addition, the transition to renewable energy is causing changes in energy policies in many countries. Massive investments in green technologies are increasingly common, but also create uncertainty for countries dependent on fossil resources. Geopolitical tactics such as the use of energy as a weapon also increase tensions, leaving countries fighting over resources and strategic transportation routes. In this context, Europe is the main focus. Its dependence on Russian gas has prompted European countries to look for alternative sources, accelerate the development of renewable energy and look for new partners in energy supplies, such as countries in the Middle East and the United States. However, this shift has not completely reduced Europe’s dependence on fossil energy, which creates new challenges in achieving sustainability goals. On a broader level, energy crises can trigger social protests and popular discontent, especially in countries with already fragile economies. When prices of fuel and basic necessities soar, political stability can be shaken. For example, countries in Africa and Latin America are prone to instability due to spikes in energy prices. This also has an impact on international relations, where countries with abundant resources can strengthen their diplomatic positions, while consuming countries seek to build alliances to improve energy security. Tensions in relations between great powers could exacerbate global frictions, triggering conflicts detrimental to long-term stability. Climate change must also be taken into account in this scenario. The energy crisis forces countries to adapt and innovate. Technology-based solutions are expected to create an alternative to dependence on fossil fuels, but this transition requires time and large investments. Delays in these changes could increase tensions and worsen the crisis. Analysis of these factors shows that the energy crisis and geopolitics are closely related. Through better international cooperation and sustainable resource management, the world’s countries can work to create more stable and secure conditions. The involvement of all parties in open dialogue is important to overcome this challenge collectively.
