All venues use 100% of the "green electricity" The Beijing Winter Olympics are "green"

People's Daily Beijing, January 13 (Zhu Jiang, Tang Jia) It is understood that during the Beijing Winter Olympics, all 26 venues in the three major competition areas will use "green electricity", which means that for the first time in the history of the Olympic Games, 100% green electricity supply will be realized in all venues. What is "green electricity"? Why should all venues of the Beijing Winter Olympics use "green electricity"? In this regard, the "Strong Observation" column of the People's Network interviewed relevant experts.

Lin Boqiang, a member of the National Energy Commission's Energy Expert Advisory Committee and dean of the China Energy Policy Research Institute at Xiamen University, said that "green electricity", that is, green electricity, refers to electricity obtained through the production process of zero carbon dioxide emissions (or close to zero carbon dioxide emissions). "Green electricity" mainly comes from clean energy, including solar energy, wind energy, biomass energy and so on. At present, China's "green electricity" is mainly based on solar photovoltaic power generation and wind power generation.

"There is no uniform definition of 'green electricity' in the world." Wang Zhixuan, vice chairman of the Expert Committee of the China Electricity Council, said that it generally refers to resource-saving and environment-friendly electric energy products such as protecting the ecological environment, reducing the consumption of resources such as water resources, not emitting or rarely emitting carbon dioxide to the environment, or neutralizing the emission of carbon di gasification. The use of "green electricity" in all venues of the Beijing Winter Olympics mainly refers to the photovoltaic power generation and wind power generation in Zhangjiakou, Hebei Province, which are fed into the Beijing power grid through the Zhangbei flexible DC power grid project, and provide guarantees for the "green electricity" operation of the Winter Olympic venues through the cross-regional green electricity trading mechanism for the Beijing Winter Olympic Games.

On the reasons for the use of "green electricity" in all venues, Lin Boqiang stressed that the benefits of using "green electricity" are obvious: First, the implementation of the "sustainable development" concept proposed by China's application for the Winter Olympics. With the help of the "Zhangbei Flexible DC Power Grid Experimental Demonstration Project", the Beijing Winter Olympics will be provided with "green electricity" generated by clean energy such as solar and wind energy, and the "green Olympic Games" will be realized, showing China's image as a responsible big country as a participant, contributor and leader in the construction of ecological civilization. The second is to demonstrate the confidence and attitude of the Chinese government in vigorously developing the clean energy industry. Emission reductions in the power sector are key measures to achieve carbon peaking and carbon neutrality goals, while the development of the clean energy industry is related to the green development of the power industry. As the first time in the history of the Olympic Games to achieve 100% green electricity supply in all venues, it reflects the positive attitude of the Chinese government towards the development of the clean energy industry. The third is to explore a new path for the integration of large-scale "transmission-grid-consumption" of clean energy. Taking the Winter Olympics as an opportunity to realize the large-scale transmission, grid connection and consumption of clean energy through the flexible DC power grid, it is conducive to accumulating valuable practical experience for building a strong, intelligent, clean and efficient large power grid.

Wang Zhixuan believes that "climate change is a major global challenge facing mankind today, and promoting the use of 'green electricity' in the country is an important starting point for strengthening the construction of ecological civilization and achieving the goal of a beautiful China, and is a major historical responsibility for China to fulfill the responsibilities of a responsible major country and promote the construction of a community with a shared future for mankind." China has put forward the carbon peak target by 2030 and the carbon neutral vision by 2060, and 'green electricity' will play the main role. ”

What role does "green electricity" play in promoting the development of clean energy? In this regard, Lin Boqiang explained that the full use of "green power" at the Beijing Winter Olympics first released the top-level support signal and played a positive role in guiding green power investment. Promoting the construction of clean energy such as wind power and photovoltaics will help improve the ability to guarantee the supply of green electricity and accelerate the construction of a new power system with new energy as the main body, and help achieve the goal of carbon peaking and carbon neutrality. Secondly, the great influence of the Winter Olympics will lead the whole society to a clean and low-carbon transformation atmosphere, help create a low-carbon environmental protection atmosphere in the society, and encourage enterprises and residents to consume green electricity. Finally, valuable practical experience has been accumulated for large-scale green electricity trading in the future. During the preparation of the Winter Olympic Games, the Beijing Electric Power Trading Center realized the green power supply of the whole life cycle from the venue to the supporting services through green electricity trading, which is of landmark significance for promoting the market-oriented trading of green electricity in the future.

Wang Zhixuan stressed that the use of "green electricity" in all the venues of the Winter Olympics is a systematic project, which needs to play the role of the entire power system of "generation, transmission, transformation, distribution, use and storage", requires the support of the technical system and policy system, requires the government and the market to work together, and needs special supporting major projects. The use of "green electricity" at the Beijing Winter Olympics is a great practice of building a new type of life force system with new energy as the main body in China, which will surely provide solid and valuable experience for China's low-carbon energy transformation.
