The global energy crisis is currently an increasingly complex issue, especially after the COVID-19 pandemic and increasing geopolitical tensions. Limited energy supplies and soaring energy prices have a significant impact on people’s daily lives, as well as the world economy as a whole. It was noted that oil prices reached record highs, while natural gas experienced extreme fluctuations. One of the main causes of this crisis is high dependence on fossil energy sources, such as oil, coal and gas. Traditional energy producing countries, such as Russia and OPEC, play a key role in regulating supply and prices. International sanctions against Russia due to their aggression in Ukraine have also limited gas supplies to European countries, causing a severe energy crisis. On the other hand, the transition to renewable energy shows positive developments. Many countries are starting initiatives to switch to cleaner and more sustainable energy sources. Solar, wind and hydro energy have become the main alternatives in the energy strategies of developed countries. Investment in energy storage and smart grid technology is also increasing to support the use of renewable energy. However, this transition is not without challenges. Existing infrastructure is often inadequate to support greater renewable energy permeability. In addition, fluctuations in the price of raw materials for solar panels and wind turbines can affect the viability of renewable energy projects. Technological developments also play an important role in overcoming this crisis. Innovations in battery technology can improve energy storage efficiency, enabling more effective use of renewable energy. Research and development (R&D) in the energy sector is a key factor in ensuring that new energy sources can meet increasing demand. Energy security is also of great concern. Countries are starting to develop policies to ensure energy availability in crisis situations. Diversifying energy sources is a top priority, with many countries looking for alternatives from various sources to reduce dependence on one type of energy. Government subsidy schemes and incentives for the renewable energy sector are expected to continue to grow. Funding from private investors also sees opportunities in sustainable projects that can provide financial benefits while paying attention to environmental impacts. Awareness of the issue of climate change is increasingly encouraging more aggressive steps in dealing with the energy crisis. International conferences, such as COP26, bring together countries to commit to ambitious greenhouse gas emissions reduction goals. Stricter environmental policies support a clean energy transition to reduce the global carbon footprint. Recent developments in the energy crisis show patterns that reflect the urgency of the transition to renewable energy and the need for technological innovation. Collective action from countries, communities and the private sector is critical to addressing existing challenges and creating a more sustainable energy system for the future.
