What does it mean to use140,000 green electricity for the Winter Olympics?

Mainly based on solar photovoltaic power generation and wind power generation, paying attention to environmental protection.

"Green power", that is, green power, refers to power with zero or close to zero carbon dioxide emission in its production process, which has lower impact on the environment than thermal power generation. The main sources of green electricity are solar energy, wind energy, biomass energy and geothermal energy. At present, solar photovoltaic power generation and wind power generation are the main sources in China.

The use of green electricity in all venues of the Beijing Winter Olympics is a concrete measure to implement the concept of "green Olympics" and fulfill the bid commitment, which plays an important role in promoting the development of clean energy and serving the construction of ecological civilization in China.

All venues of Beijing Winter Olympics have achieved full coverage of urban green power grid, and the lighting, operation and transportation of venues are all provided by photovoltaic power generation and wind power generation in Zhangjiakou, Hebei. Green power generated by clean energy sources such as wind energy, solar energy and biomass energy in Zhangbei area is input to Beijing power grid through Zhangbei flexible DC power grid project, and through the cross-regional green power trading mechanism suitable for Beijing Winter Olympics, the venues in Beijing Division are illuminated and the "green operation" of the Winter Olympics venues is guaranteed.
