How does the Paris Olympics apply photovoltaics?

The "2024 Paris Olympics" is an international Olympic event held in Paris, France. The opening of this Olympic Games will be on July 26, 2024, local time. The competition of some events will start on July 24. There are 32 major events, 329 minor events, and a total of 206 countries and regions will participate.

The goal of the 2024 Paris Olympics and Paralympics is to halve carbon dioxide emissions, and the French Electricity Group will provide 100% renewable electricity generated by wind and solar power plants.

The site of the Paris Olympic Village is set in Pleyel on the Seine River. A total of 82 buildings and about 3,000 apartments have been built.

95% of the venues of the 2024 Paris Olympics use existing venues and temporary venues, which is an effective way to reduce carbon emissions and energy consumption. The beds of athletes in the apartments are made of corrugated cardboard, and there is no air conditioning in this Olympic Village, which is equipped with more than 8,000 fans.

The Paris Olympic Village will use a "geothermal cold water circulation" cooling system, which will draw water from the Seine to cool the air, and then circulate it through pipes to reduce the overall temperature of the building, helping to achieve the ambitious goal of halving carbon emissions for this Olympic Games.

Photovoltaic has become the main force in achieving the carbon reduction goal of the Paris Olympics. One-third of the roofs of the buildings in the Paris Olympic Village are equipped with photovoltaic panels, and the other one-third have roof gardens.

Among them, as the only newly built venue for the 2024 Paris Olympics and will continue to be used after the games, the 5,000-square-meter roof of the Olympic Aquatics Center in Saint-Denis is covered with solar photovoltaic panels, which can meet at least 20% of the venue's electricity needs, making it one of the largest solar power plants in public buildings in the Ile-de-France region.

In addition, there is a solar power plant floating on the Seine. This floating power plant is covered with 400 square meters of high-efficiency photovoltaic panels, which can generate 78 kilowatt-hours of electricity and can power 94 apartments in the Olympic Village and Paralympic Village.

A temporary solar photovoltaic roof is installed above the transfer hall of the Olympic Village. This roof can not only provide shade for athletes, but also supply electricity to nearby buildings. Photovoltaic energy conservation and emission reduction for the Olympic Games began as early as the 2008 Beijing Olympic Games. A solar photovoltaic power generation system with a total installed capacity of 130 kilowatts was installed above the 12 main passages of the Beijing "Bird's Nest". The electricity generated by the solar photovoltaic power generation system of the Bird's Nest will be directly incorporated into the power supply system of the National Stadium, which will play a good role in supplementing the power supply of the Olympic venues.
