The European Union (EU) faces serious challenges in overcoming the deepening energy crisis amidst geopolitical conflicts and climate change. To respond to this situation, the EU introduced a series of new policies aimed at increasing energy security and promoting the transition to renewable energy. One of the main policies is increasing investment in renewable energy. The EU is committed to injecting large funds into solar, wind and biomass projects. As part of the European Green Energy Plan, an ambitious target was set to increase the proportion of renewable energy to 45% by 2030. This will reduce dependence on imported fossil fuels. Implementing energy efficiency is also a focus, with initiatives encouraging the industrial and household sectors to adopt energy-saving technologies. The incentive program is expected to encourage the use of more efficient equipment, while reducing overall energy consumption. For example, financing for heating and cooling system improvements has become more accessible. Energy source diversification policies are also strengthened. The EU is expanding cooperation with countries producing alternative energy, and strengthening interconnection networks between countries. This initiative aims to reduce the risk of energy supply disruptions and create a more integrated energy market. By expanding gas pipelines and electricity connections, the EU is trying to create alternative routes in energy distribution. Another proposed initiative is the establishment of strategic energy reserves. It proposes the collection of energy stocks to face sudden crises. These reserves aim to guarantee sustainable energy access during difficult times and protect consumers from price fluctuations. The transportation sector also did not escape attention. The EU targets reducing emissions from this sector by encouraging the use of electric vehicles and providing adequate charging infrastructure. Incentives for consumers to switch to electric vehicles will increase demand and accelerate the transition to sustainable transportation. In the context of energy security, stricter competition policies are established towards large energy companies. The European Union seeks to prevent monopolies and ensure that prices remain affordable for consumers. The new regulations will also include price transparency and consumer protection. The EU also emphasizes the importance of societal involvement in the energy transition. Through educational campaigns, it is hoped that the public will be more informed and participate actively in efforts to reduce energy consumption and implement clean energy practices. This latest policy is expected not only to overcome the energy crisis, but also to prepare the European Union to face greater environmental challenges in the future. Strategic integration and collaboration between countries are the keys to success in implementing these initiatives. With these steps, it is hoped that the EU can secure a sustainable and environmentally friendly energy supply and reduce the deepening impacts of climate change.
