Case study: Effects of hydroelectric dams (3 gorges dam) Introduction/research question: The Three Gorges Dam spans the Yangtze in China. Construction began in 1994. It is the largest hydroelectric dam in the world. So far china has benefited very well economically from renewable energy production and pollution and the burning of fossil fuels has been avoided and this source of energy has become vastly popular. However not everyone is happy with the construction of this dam as it has its benefits and limitations. So was this hydroelectric dam worth building why or why not? Let us find out. Benefits of the 3 gorges dam in China: Flood control, hydroelectric power, and Trade Flood Control: 2,300 years ago, there have been 214 major floods recorded,…show more content…
The Three Gorges area of the Yangtze is notorious for dangerous shipping conditions. Thus the controlled level of water and the ship lock system will enable larger ships to travel further inland on the Yangtze and that will be capable of lifting passenger or cargo ships of 3,000. Limitations of the 3 gorges dam: Flooding: Just as we thought the problems of flooding had stopped, the 400 mile long reservoir of the Three Gorges Dam has flooded 13 cities, 140 towns, 1352 villages, and 100,000 acres of China’s most fertile farm land. The agriculture areas along the river have produced nearly half the country’s total crop production. The farm land lost had provided 40% of China’s grain and 70% of rice crops. Farmers that were relocated to the hillsides of the dam have struggled to grow crops, and so far the only viable crop able to be produced on such steep terrain has been oranges. Financing: The United States Export-Bank and the World Bank refused to finance the project because of its disastrous environmental and social consequences such as Water Pollution, Siltation Ecosystem Disruption and Deforestation. In addition the compensation funds amount to 46% of the total project costs for the dam, or $7.15 billion US dollars. In addition to cover the costs they had to look for external funding, which came from the top five investors in the project are Germany, Sweden, Switzerland, Brazil, and
