Gorges

produced from renewable energy sources. One very controversial aspect to the use of these renewable energy sources is how they are changing the landscapes and some even displacing animals and humans form their homes. One example of this is the Three Gorges Dam, a hydroelectric dam that reaches across the Yangtze River. The dam is located near the town of Sandouping in the Hubei province. When the dam was being built China had to relocate over 1.24 million people because the water that would be blocked

they are built, a vast swath of land must be used, resulting in displacement of local people. The amount of land needed to build a dam is large which will displace many people. When the Three Gorges Dam project was approved, it forced over 1.4 million people to relocate (Business Insider). The Three Gorges Dam needed to be a large dam because of the growing energy needs in China. This would require vast areas of land and so the amount of people relocating increased due to the dam because of the flooding

significantly help jobs in the development industry (Perlman). However, these dams are extremely costly, not just economically but environmentally and socially as well. These costs can be demonstrated by looking at the consequences of other dams. Three Gorges in China: release of methane gases, deforestation, water pollution, ecosystem disruption. Glen Canyon Dam: sedimentation, endangerment and extinction of species endemic to the area, poor water quality, crippling of ecosystems downstream—and these

Hydroelectric power: The World's Established Renewable Energy Resource For over a century, hydroelectric power has been used to generate electricity from falling water. The capacity to produce this energy is dependent on both the available flow and the height from which it falls. Hydroelectric dams create height for the water to fall and provide storage. In general, the higher the dam, the more potential energy is available. Building up behind a high dam, water accumulates potential energy. The

The signs are alarming. We as citizens, business owners, and activists must stand up and make a change to create a more sustainable way of growing our populations and societies. Sustainability needs to become more implemented into the structure of corporations, cities, and countries. China, the most populous country in the world, is projected to have an insufficient supply of water by the year 2025. On top of the shortage of water China is facing they also have a major issue with water pollution

Renewable energy has become a widely popular topic in society. With the rapid depletion of fossil fuels, scientist are looking to natural and renewable resources to create a means to produce sustainable energy. There are many alternative energy sources that have proven useful in the past couple of years. Some of the alternative energy sources are not only more useful than others but have proven to be easier to attain and also prove to create a more substantial amount of energy. Today, the most widely

many riverbanks face these problems of instability and overpopulation has led to more civilisations becoming at risk of mass failure. Ultimate failure of a mass of soil is currently the most important threat to the long term stability of the Three Gorges dam (the largest dam in the world) and the 6300 km long Yangtze river, where up to 41.1% of the river basin area suffers from soil erosion problems (People's Daily Online, 2001). Slope stability is a largely researched topic and numerous models, failure

are not possible without causing some environmental degradation. Construction is one of the main reasons for this, for any development to take place an area must be used efficiently to maximize space for development. A great example of this is the 3 Gorges Dam in China; this cost over $25 billion to build. Yes, it was financially positive, however a lot of land was taken, which led to huge disruptions in local ecosystems. Also china has a huge demand for Iron; this is in order to build the buildings

developed in the TGRR including Dalaoling (Yichuang City, Hubei Province), Longmuhe (Xinshan County, Hubei Province), Shiping (Fengdu County, Chongqing), and Wushan (Wushan County, Chongq- ing) (Zhang. 2011). 7 Conclusion This paper takes the Three Gorges Dam Program as an example to introduce the process of EIA, emphasizing on the impact and mitigation these two phases during the allover management. Among several analysis methods, we focus on the Cost-Benefit Analysis (CBA) methods to evaluate the

For centuries, scientists and energy experts from all over the world have been making efforts to look for alternative resources in order to solve human being’s energy crisis. Consequently, a great number of renewable energy source have been discovered, including solar power, nuclear power, wind-generated power and hydroelectric power. This essay aims at giving some basic knowledge on hydroelectric power technology with focuses on its impacts on environment. Firstly, a brief introduction of hydroelectricity
