The energy crisis in Europe has become one of the most pressing issues in recent years, especially in the wake of rising geopolitical tensions and the impact of the COVID-19 pandemic. A number of factors contributed to recent developments in this crisis, with a primary focus on dependence on fossil energy sources, energy diversification efforts, and increasing energy security at the regional level. One of the main concerns is Europe’s dependence on natural gas from Russia. After Russia’s invasion of Ukraine, many European countries began looking for alternatives to reduce this dependence. Concrete steps have been taken, including purchasing gas from other countries and channeling investment to improve gas infrastructure. Countries such as Norway and Qatar are now the main choices, while several European countries are also accelerating the development of renewable energy sources. These changes also create pressure to accelerate the transition to renewable energy. Most European governments have committed to reducing carbon emissions by 55% by 2030 and achieving net-zero emissions by 2050. Renewable energy projects, especially wind and solar, are expanding rapidly. In this context, Germany and Spain have taken the lead in installed wind power capacity, while the Scandinavian countries are making optimal use of hydroelectric potential. Apart from that, Europe also faces challenges related to energy prices which continue to rise. The surge in gas and electricity prices has an impact on inflation and people’s purchasing power. The governments of many countries, including France and Italy, have implemented energy subsidy policies to help households and businesses. However, long-term solutions are needed to stabilize energy markets. The diversification strategy also includes the development of green hydrogen as a future energy source. Countries such as Germany and the Netherlands are investing in hydrogen infrastructure, creating an ecosystem that supports the production and distribution of hydrogen from renewable energy. These so-called “green” projects aim to make hydrogen part of a cleaner energy supply. Community and private sector involvement also plays an important role in overcoming this crisis. Many companies are now turning to sustainability and energy efficiency practices in response to the demands of more environmentally conscious consumers. Investments in smart technology promise more efficient energy management, with automation and optimization of energy use. Looking ahead, the shift towards renewable energy and efforts to increase energy security in Europe are important steps. Cooperation between countries is also key in creating a stronger energy network. The European Union acts as a mediator to coordinate these efforts, with energy interconnection projects linking various member states. With various efforts being made, hope for overcoming the energy crisis in Europe remains. The sustainability of the energy transition will depend heavily on the commitment of all stakeholders, including government, industry and society at large, to adapt and create a more sustainable energy system.
