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 Reservoir Region 300–340 days. The annual runoff flow at the site of the dam of the Three Gorges Project is 451 billion m³ with the annual sediment discharge of 530 million tons. The Three Gorges abounds in water resources, ecological resources, tourism resources, and the resources of some ores, which have a great potential for exploration. The Yangtze River flows through the Three Gorges Reservoir Region with the good conditions for water transportation and the water-resources development. The potential installed capacity of hydropower can be about 30,000 MW in the Three Gorges Reservoir Region where the water resources are the most abundant
