The impact of the Russian-Ukrainian war starting in 2022 has created a deep global energy crisis. Surging energy prices, especially natural gas and oil, are a major concern around the world. European countries that are highly dependent on energy supplies from Russia are trying to find alternatives to meet their energy needs. Russia, as one of the largest gas exporters, is reducing supplies to Europe, causing concerns about energy availability during the winter. Rising energy prices directly impact inflation, affect the cost of living for consumers and disrupt the industrial sector. Many factories are facing surging operating costs due to high energy prices, leading to reduced production. On the other hand, other energy producing countries, such as the United States, have increased production and exports of liquefied natural gas (LNG) to help fill supply shortfalls in Europe. However, inefficiencies in distribution infrastructure and high transportation costs still make this solution not completely adequate. Therefore, Europe is starting to invest in renewable energy and interconnection projects to reduce dependence on fossil energy. The impact of this crisis also spread to developing countries. Many countries with economies dependent on fossil energy are experiencing difficulties due to soaring prices. Rising energy prices often trigger social unrest, as people demand the government take action to protect them from the impact of rising lives. The transition to renewable energy is a long-term solution for many countries. Investments in solar, wind and biomass energy are increasing rapidly in response to this energy crisis. Countries such as Germany and Denmark are pursuing ambitious programs to achieve energy security and reduce carbon emissions. In international diplomacy, the energy crisis has prompted countries to seek new partnerships. Alternative energy sources in Australia, Qatar and African countries are gaining attention as drivers of energy supply diversification. Global initiatives to improve energy efficiency are also increasing, with a focus on technological innovation to reduce energy consumption. This crisis touches on environmental aspects, with high consumption of fossil energy contributing to climate change. Many experts say that this war is a call to prioritize the global energy transition. International cooperation is needed to achieve sustainability goals while ensuring energy security. Overall, the global energy crisis resulting from the Russo-Ukrainian war is a reminder of the vulnerability of the world energy system. Dependence on one energy source can have far-reaching consequences, both economically, socially and environmentally. Stimulation to switch to renewable energy sources and environmental conservation should be the main agenda throughout the world to face future energy challenges.
