The energy crisis in Europe has reached a critical point, especially following rising geopolitical tensions and stringent environmental policies. In recent months, European countries have struggled to achieve energy security while also switching to renewable energy sources. The crisis has been exacerbated by cuts in natural gas supplies from Russia, traditionally the main provider. As a result, energy prices have skyrocketed, severely impacting industry and consumers. One of the main responses is to diversify energy sources. Many countries are now turning their attention away from dependence on Russian gas by seeking supplies from other countries, such as Norway, Qatar and the United States. The signing of long-term contracts and the construction of new infrastructure, such as LNG (liquefied natural gas) terminals, are underway to facilitate this change. In addition, Europe is increasingly investing in renewable energy such as wind, solar and biomass. Targeting an increase in renewable energy capacity, the European Union plans to reach 40% of total energy consumption by 2030. Government regulations also play a big role in this crisis. European Union member states have been ordered to reduce gas consumption by up to 15%, with emergency measures including reducing heating in public and industrial buildings. The recovery package as well as subsidies for green energy aim to protect consumers pressured by soaring prices. However, this policy was not always popular, and public protests often occurred in various large cities. Europe also faces logistical problems regarding energy distribution. In this emergency, electricity supply has become a major concern, especially in countries that rely heavily on gas energy for electricity generation. Therefore, investment in energy networks and interconnections between countries is very important to ensure energy stability and security. Technological innovation also serves as a driver of solutions to this crisis. Research projects in energy storage, such as batteries and hydrogen technology, are increasingly active. In this way, Europe is not only addressing short-term problems but also creating the foundations for a more sustainable future. In facing this crisis, solidarity between member countries is very important. In this context, cross-border cooperation can improve energy efficiency and accelerate the transition to clean and renewable energy sources, which can ultimately reduce the impact of the current crisis.
