Three Gorges Dam Development and Reform Commission of China, 366 grams of coal would produce 1 kWh of electricity during 2006. At full power, Three Gorges reduces coal consumption by 31 million tonnes per year, avoiding 100 million tonnes of greenhouse gas emissions, millions of tonnes of dust, one million tonnes of sulfur dioxide, 370,000 tonnes of nitric oxide, 10,000 tonnes of carbon monoxide, and a significant amount of mercury. Hydropower saves the energy needed to mine, wash, and transport the coal from northern China. From 2003 to 2007, power production equaled that of 84 million tonnes of standard coal, reducing carbon dioxide
Three Gorges Dam The project used of concrete (mainly for the dam wall), used 463,000 T of steel (enough to build 63 Eiffel Towers), and moved about of earth. The concrete dam wall is high above the rock basis. When the water level is at its maximum of above sea level, higher than the river level downstream, the dam reservoir is on average about in length and in width. It contains of water and has a total surface area of . On completion, the reservoir flooded a total area of of land, compared to the of reservoir created by the Itaipu Dam. The
