The global energy crisis is currently an increasingly urgent and relevant issue for various countries in the world. One recent development that stands out is the transmission from dependence on fossil fuels to renewable energy sources. The rise of renewable energy such as solar, wind and hydro is a major highlight in efforts to combat this crisis. Countries such as Germany and China have demonstrated a major commitment to investment in the renewable energy sector, reducing carbon emissions and increasing energy efficiency. Furthermore, geopolitical conflicts also contributed significantly to this crisis. Tensions between energy-producing countries, such as Russia and Western countries, have disrupted global energy supplies, causing oil and gas prices to spike. Energy that was initially stable has now become highly vulnerable to fluctuations caused by political policies and shifts in global power dynamics. On the other hand, energy storage technology is developing rapidly. Innovations in lithium-ion batteries and other energy storage technologies are increasingly enabling renewable energy systems to compete competitively with traditional energy sources. This allows consumers to store energy from renewable sources, giving them more control over their daily energy use. The energy crisis has also spurred many countries to increase the efficiency of energy use. Energy savings programs, such as replacement of energy-saving lighting and better building insulation, are being implemented in various locations. It is hoped that these steps can reduce energy consumption while lowering costs for consumers. At the international level, the COP28 meeting scheduled to be held at the end of this year is an important platform to discuss countries’ commitment to overcoming the energy crisis. The main agenda is the progressive reduction of carbon emissions, as well as achieving the targets of the 2015 Paris climate agreement. Investment in new technologies is also increasing, especially in the development of green hydrogen energy. Hydrogen is considered a potential solution for storing energy and providing a cleaner fuel alternative. Many companies, including automotive and energy giants, have invested heavily in research and development of hydrogen as an energy source. Furthermore, the integration of smart energy systems and smart networks is also increasingly being implemented. This technology helps in the management of energy use and more efficient distribution, reducing waste and improving response to changing energy demands. By adopting these measures, countries are trying not only to overcome the energy crisis, but also to provide energy security for future generations. New policies, programs and innovations will be key in the journey towards a more sustainable and efficient energy system.
