The global energy crisis has become an urgent problem in various parts of the world. Soaring energy prices, supply uncertainty, and the impact of climate change are forcing many countries to evaluate and change their energy policies. In this context, the shift towards renewable energy and energy efficiency is increasingly becoming a major focus. Fossil energy producing countries, such as Russia and Saudi Arabia, face pressure to diversify their economies. Geopolitical uncertainty and international sanctions have accelerated the tightening of energy policy. Today, many countries are investing in green technologies, such as solar and wind, which offer sustainable solutions with a lower environmental impact. Proactive policies in the renewable energy sector, driven by fiscal incentives and government support, have the potential to create new jobs and stimulate economic growth. In Europe, the response to the energy crisis was characterized by programs to reduce dependence on fossil energy. Many countries have announced plans to cut greenhouse gas emissions, in line with global climate change goals. This strategy includes developing infrastructure for electric vehicles and implementing better energy storage technologies. On the other hand, developing countries face greater challenges in the energy transition. Limited resources and inadequate infrastructure make the shift to renewable energy a more difficult task. However, international institutions are now paying increasing attention to these countries, pushing for access to clean technologies and financing for renewable energy projects. The energy crisis also motivates technological innovation. For example, the development of smart grids capable of managing energy consumption efficiently is becoming increasingly relevant. Solutions like these not only help stabilize energy supplies but also make it easier for users to manage their consumption. In the context of public policy, collaboration between government, the private sector and civil society is becoming increasingly important. Initiatives that involve all stakeholders can create policies that are more inclusive and responsive to local needs. Developing policies based on data and in-depth analysis will strengthen the effectiveness of the steps taken. Success in dealing with the global energy crisis is highly dependent on long-term commitment. The policies designed must not only be reactive to the current energy emergency, but must also be visionary, establishing a framework that supports innovation and investment in the future. Through an enterprising and collaborative approach, countries around the world have the potential to create energy systems that are not only sustainable, but also fair and inclusive for all levels of society.
