The 24th Winter Olympics will kick off in Beijing on February 4, 2022.

The Sports Department of Chinanews.com has launched a series of column "Hundred Questions about the Winter Olympics", which aims to popularize the knowledge of the Winter Olympics, answer hot questions, share interesting stories of ice and snow, and help everyone have a better viewing experience at the Beijing Winter Olympics.

How many tons of emission reduction can the 92nd "green power" help Beijing Winter Olympic venues reduce?

  With the full operation of the world's first flexible DC power grid project from Zhangbei to Beijing, all venues of the Beijing Winter Olympics will use 100% green electricity for the first time in Olympic history.

And behind this historical initiative, what kind of persistence and dedication does China have in hosting the Olympic Games in a green way?

How many tons of carbon dioxide can "green electricity" help the Winter Olympic venues reduce?

  "Green Olympics" is one of the Olympic legacy left by the Beijing Olympics.

"Hosting the Olympics in a green way" has also become a specific expression of "sustainable development", one of the three concepts proposed by Beijing when it bids for the 2022 Winter Olympics.

  Green power refers to the use of specific power generation equipment, such as wind turbines, solar photovoltaic cells, to convert renewable energy such as wind energy and solar energy into electricity.

Adhering to ecological priority, resource conservation and environmental friendliness is also one of the core concepts of the preparations for the Beijing Winter Olympics.

  "The wind in Zhangjiakou lights up the lamps of Beijing".

The Zhangbei Flexible DC Project is the world's first four-terminal flexible DC power grid that transmits large-scale wind power, photovoltaics, pumped storage and other energy sources. It will send clean energy from Zhangjiakou to the Beijing-Tianjin-Hebei region.

At present, wind power and photovoltaic power from Zhangjiakou can deliver 14 billion kWh of "green electricity" to Beijing every year, which is one-tenth of Beijing's annual electricity consumption.

  According to estimates, by the end of the 2022 Winter Paralympic Games, the Winter Olympic venues are expected to consume about 400 million kWh of green electricity, which is expected to reduce standard coal burning by 128,000 tons and carbon dioxide emissions by 320,000 tons.

  Juan Ann Samaranch, chairman of the Beijing Winter Olympics Coordination Committee of the International Olympic Committee, once spoke highly of this, saying: "The Beijing Winter Olympics will be the first Olympic Games to achieve 'all-green', and the host Green and sustainable development in a wider range has a benchmarking role."
