The current global energy crisis has a major impact on the world economy. In 2021 and 2022, the surge in energy prices will be driven by a variety of factors, from post-pandemic recovery to geopolitical conflicts. Rising prices of oil, gas and other fuels have a direct impact on production costs and inflation in many countries. One of the main causes of the energy crisis is the world’s dependence on fossil fuels. Energy producing countries, such as Russia, Saudi Arabia and the US, play a key role in global supply. Political tensions, especially after Russia’s invasion of Ukraine, led to supply disruptions and increased market speculation. This has an impact on energy prices soaring, creating a risk of stagflation in countries that depend on imported energy. On the other hand, the energy transition towards renewable energy sources is increasingly urgent. Countries are seeking to reduce dependence on fossil fuels and invest in renewable energy such as wind, solar and hydro. However, this transition requires time and major investment. In many countries, the infrastructure to support renewable energy is not yet fully ready, thus affecting the stability of energy supply. Inflation is one of the direct impacts of the energy crisis. Rising energy prices impact the prices of other goods and services, creating inflationary pressures around the world. Central banks in various countries, including the US and Europe, are pursuing tighter monetary policies to tackle rising inflation, in the hope of stabilizing the economy. The energy crisis also affects the industrial sector. Communication and transportation become more expensive, which has the potential to hinder economic growth. Several small companies were forced to stop operations due to unaffordable energy costs. The manufacturing sector, which is highly dependent on energy, experienced a significant decline in productivity. The economies of developing countries, already vulnerable, have been further strained by the crisis. Many countries that depend on energy commodity exports are now facing challenges in recovery. Rising energy prices also threaten social stability, causing protests and tensions in society, if the cost of living continues to rise. Global initiatives to diversify energy sources are increasingly being encouraged. International parties are trying to establish cooperation in clean energy technology and energy efficiency. However, achieving these targets is still hampered by various problems, including inconsistent government policies and resistance from the traditional energy sector. In an investment context, the energy crisis has attracted investors’ attention to turn to renewable energy opportunities and energy-saving devices. This creates the potential for new economic growth, but also requires strong policy support from the government and public awareness of the importance of sustainability. The global energy crisis shows how complex the interactions between energy markets and the economy are. Without appropriate strategic steps, the impact of this crisis will continue to spread, affecting people’s daily lives and global economic stability. Building energy security and investing in innovation will be key to overcoming existing challenges and achieving sustainability in the future.
