Shanghai World Expo is the first official presentation of the "low carbon" concept Expo. There is large-scale implementation of solar energy, new energy vehicles, smart grid, LED lighting demonstration application.
The Smart Grid Demonstration Project is located in the World Expo Park. Known as an "Energy Heart", a 110kV intelligent substation in the B1 of State Grid Pavilion supplies electric power for the whole Park. With low-carbon and green concept, this substation is using ground source heat pump, heat collection, ice storage and other new technologies to achieve energy recycling . Up till May 2010, the total electricity consumption had reached 348.2 kWh, in which 208.9 kWh is from renewable generation. 
The solar panels on the theme pavilion roofs covers more than 30,000 square meters, making it the world's largest signal solar roof. Total capacity of more than 4.68 MW solar power facilities have been installed on China Pavilion, Theme Pavilion, Expo Center, Cultural Center and other landmarks roof and glass curtain walls to reduce emissions of carbon dioxide 4000 tons per year, which makes it the largest domestic demonstration area of solar photovoltaic cells.
At the same time, Shanghai World Expo will become the world's largest demonstration project of new energy vehicle. A total of over 1,000 new energy vehicles are running in and around the World Expo Park. Shanghai World Expo site are using new energy vehicles to achieve zero emission public transport: 120 electric passenger cars, 36 super-capacitor buses and six fuel cell vehicles, running for public transportation; 140 electric pavilion vehicles and 100 fuel cell sightseeing car, specifically to satisfy public demand.
The entire demonstration zone includes 9 model projects and 4 demo projects.
