In the context of global climate change becoming an increasingly serious challenge, the transition to green, clean and sustainable energy sources has become an inevitable trend. These advances not only contribute to environmental protection, but also open up new economic growth opportunities based on green technology.

For decades, Germany has been a role model for the green energy transition, known as the “Energiewende” in the country. This is not just a simple energy strategy, but a large-scale economic and social project aiming at a low-carbon, sustainable and environmentally friendly economy. Germany’s achievements in this area reflect a combination of policy vision, technological investment and social awareness of climate protection.

One of Germany’s greatest successes has been the massive expansion of renewable energy, especially wind and solar power. Since the early 2000s, the German government has introduced feed-in tariffs to encourage households, businesses and communities to produce electricity from renewable sources. As a result, more than 50% of Germany’s electricity now comes from clean energy sources, with the rate exceeding 60% at times. This has helped Germany significantly reduce its dependence on fossil fuels, while gradually phasing out nuclear power according to its announced roadmap.

In addition to developing renewable energy, Germany also focuses on improving energy efficiency. Many industries apply energy-saving technology, reduce emissions while maintaining high productivity. Innovation programs in the construction sector are also implemented, encouraging environmentally friendly building designs and efficient energy use. The government also supports people to switch to green transportation, in which electric vehicles are increasingly popular thanks to the rapidly expanding charging infrastructure.

Germany’s achievements are not only in numbers, but also in its global leadership. The country has demonstrated that a combination of consistent policy, investment in science and technology and social consensus can create an efficient and sustainable green energy system. The “Energiewende” model has become an inspiration for many other countries in their energy transition efforts, while also consolidating Germany’s position as one of the world’s leaders in the field of climate change response and sustainable development.

Denmark

Denmark is considered one of the world's most successful and pioneering countries in the green energy transition. Since the 1970s, after the oil shocks, the country has shaped a long-term development strategy to reduce its dependence on fossil fuels and maximize the potential of renewable energy sources. After more than half a century, Denmark has not only achieved impressive achievements in clean energy production, but has also become a global model in linking economic growth with environmental protection.

One of Denmark's most notable achievements is the development of wind power. This country is known as the "cradle" of the modern wind turbine industry, with world-leading corporations such as Vestas or Ørsted. Denmark was also the first country to build offshore wind farms and currently, more than 50% of the total electricity consumed in the country comes from this energy source. Not only meeting domestic demand, Denmark also exports wind power technology globally, playing an important role in promoting renewable energy in many other countries.

In addition to wind power, Denmark also focuses on energy efficiency through centralized heating systems and improved urban infrastructure. Danish cities are known for their environmentally friendly solutions, notably Copenhagen, which aims to become the world's first carbon-neutral capital by 2025. Green transport systems, especially the promotion of bicycles and low-emission public transport, have contributed significantly to reducing greenhouse gases.

The Danish government has also set ambitious goals for a net-zero emissions economy by 2050. This roadmap is supported by policies that encourage investment in renewable energy, promote technological innovation and create conditions for strong private sector participation. As a result, Denmark has maintained stable economic growth while building its image as a leading country in sustainable development.

With its determined steps and successes, Denmark is considered a shining example for other countries to follow in the process of moving towards a clean and sustainable energy future.

China

Over the past two decades, China has emerged as one of the most influential countries in the global green energy transition. As the world’s second-largest economy and the world’s top greenhouse gas emitter, China faces enormous pressure to reduce pollution and promote sustainable development. The country has turned the challenge into momentum, achieving impressive results in expanding renewable energy and green technology innovation.

One of China’s most notable successes has been its remarkable development of solar and wind power. China now accounts for more than a third of the world’s total solar capacity and is also the world’s largest installed wind power capacity. Massive solar farms in the Gobi Desert and offshore wind projects on the coast have become symbols of the country’s strong breakthrough in the field of green energy. The rapid expansion has not only helped China gradually reduce its dependence on coal, but also contributed to reducing the cost of renewable energy technology on the international market.

In addition to renewable energy, China is also leading the world in the electric vehicle revolution. With subsidies, an expanding charging infrastructure, and the participation of large corporations such as BYD and NIO, China has created the largest electric vehicle market in the world. Millions of green vehicles are on the road every year, helping to reduce the burden of emissions in the transport sector – one of the biggest sources of pollution in urban areas.

Notably, China is also investing heavily in new technologies such as energy storage batteries, smart grids and green hydrogen. These efforts are aimed at addressing the challenge of stability in the power system as the proportion of renewable energy increases. At the same time, sustainable development policies are integrated into economic and social development plans, demonstrating China's commitment to achieving carbon neutrality by 2060.

China’s achievements in green energy transition are not only significant nationally, but also have a strong impact on global trends. With its market size and technological capabilities, China is playing a key role in shaping the world’s clean energy future.
