The global energy crisis hitting Europe is currently one of the most important issues in geopolitics and economics. The main causes of this crisis are long-standing geopolitical tensions, especially between Russia and Western countries, coupled with the impact of climate change and the need for transit towards renewable energy. One of the main contributing factors is Europe’s increasing dependence on Russian natural gas. Approximately 40% of Europe’s gas supplies come from Russia, and when the conflict in Ukraine began in 2022, a gas supply cutoff occurred which had a significant impact on European countries. These tensions have led to drastic spikes in energy prices, straining family and industrial budgets. Switching to renewable energy sources is indeed a strategic step, but this process requires time and large investment. Many European countries are trying to switch from coal and natural gas to renewable energy such as wind and solar power. However, this transition is often hampered by inadequate infrastructure and high initial costs. In Germany, for example, its energy project, known as “Energiewende,” seeks to reduce carbon emissions by closing coal-fired power plants. However, alternative gas reserves are not yet sufficient to meet current needs, leading to concerns about energy shortages in winter. Countries such as France and Italy are also struggling to adapt to this situation. France, which relies more heavily on nuclear power, is experiencing some problems at its plants, which are reducing its electrical energy production capacity. On the other hand, Italy is trying to reduce dependence on Russian gas by seeking supplies from other countries, such as Algeria and Azerbaijan. The impact of this energy crisis is not only felt by the industrial sector, but also by consumers. In an effort to respond to soaring prices, governments across Europe are implementing a variety of policies, from energy subsidies to limits on electricity consumption. However, these measures are often only temporary and do not solve the underlying problem. The transportation and mobility sectors are also affected. Soaring fuel prices are adding pressure to the economy, prompting governments to encourage the use of electric vehicles. However, expanding charging infrastructure and the need to invest in battery technology pose challenges. Reflecting on potential solutions, regional cooperation becomes very vital. Programs such as European-level energy agreements and joint efforts in the development of green technologies are important for creating greater energy security in the future. Increasing environmental awareness is also helping to encourage some people to adapt to a more sustainable lifestyle. Local initiatives in maintaining energy efficiency and wise use of resources are a positive trend amidst this crisis. This crisis presents major challenges for Europe, but also opens up opportunities to innovate and transform towards a more sustainable and resilient energy system.
