Recent developments in the global energy transition show significant changes in policy, technology and investment aimed at shifting dependence from fossil energy sources towards renewable energy. This transition is reinforced by the urgent need to address climate change and reduce carbon dioxide emissions. Based on the latest data, more than 170 countries have set net-zero emissions targets, with various strategies to achieve them. One of the main drivers of this transition is technological innovation in renewable energy. The solar and wind sectors continue to progress, with significant cost reductions. According to the International Renewable Energy Agency (IRENA), global solar energy costs have fallen by more than 80% since 2010. This makes renewable energy increasingly competitive compared to fossil fuels. Investment in the renewable energy sector is also increasing rapidly. In a BloombergNEF report, global investment in renewable energy reached more than $500 billion in 2022, with 2023 predicted to see that figure grow further. Countries such as China and the United States are key players in driving this investment, providing infrastructure and volunteers for research and development of new technologies. The role of government policy is also no less important. Many countries are now implementing tax incentives, subsidies and environmentally friendly regulations to encourage the use of renewable energy. The European Union, for example, implemented the European Green Deal, which aims to reduce greenhouse gas emissions by at least 55% by 2030. This kind of policy not only facilitates the energy transition, but also opens up new jobs in the green sector. At the local level, many cities are starting to adopt a zero emissions vision by integrating renewable energy in urban development plans. For example, several European cities have introduced electricity-based transportation systems that are integrated with renewable energy networks, creating a more sustainable ecosystem. However, the global energy transition also faces challenges. Reliance on raw materials for renewable energy, such as lithium and cobalt for batteries, can have serious environmental and social impacts. Therefore, it is important to develop recycling technologies to minimize waste and increase resource use efficiency. Overall, the global energy transition towards sustainability not only benefits the environment but also offers new economic opportunities. By continuing to focus on research, supportive policies, and international cooperation, the world can achieve sustainable clean energy goals and mitigate the impacts of climate change.
