an ongoing renewable energy debate‚ the debate on biofuels include the food vs fuel dilemma and the Indirect land use change impacts of biofuels. The debate on hydropower installations usually revolve around the footprint of dam floodplains‚ with for example the Three Gorges dam‚ the largest renewable electricity source in the world‚ having displaced 1.3 million people‚[3][4] and garnered environmental criticism.[5] The debate on new renewables‚ such as wind and solar‚ is usually much less intense

hydroelectricity producer‚ with 721 terawatt-hours of production in 2010‚ representing around 17 percent of domestic electricity use. There are now three hydroelectricity plants larger than 10 GW: the Three Gorges Dam in China‚ Itaipu Dam across the Brazil/Paraguay border‚ and Guri Dam in Venezuela. The cost of hydroelectricity is relatively low‚ making it a competitive source of renewable electricity. The average cost of electricity from a hydro plant larger than 10 megawatts is 3 to 5 U.S. cents

!! As you know “Dams” are constructed across the water ways to control the flow or raise the level of water. (show the dams in the models Dams are constructed either with earth‚ rock or cement concrete Now a days most of the dams are constructed using concrete which is more expensive. Therefore the cost of construction of even a smaller size dam involves spending of crores of rupees !!!!!! So we should try to reduce the cost of construction of dams without compromising the

Dams are a huge threat to the mighty Salmon of America. Although there are solutions to dams they are not enough to save the species. Salmon are slowly becoming extinct due to dams‚ because dams are cutting off rivers to and from the ocean and preventing them to spawn. Salmon were thriving in the U.S. before hydropower dams were established. Salmon are the most extraordinary fish on the planet‚ they make an extremely long journey that start when they are only a little smelt and finish in adulthood

hydro power ADVANTAGES: * Once a dam is constructed‚ electricity can be produced at a constant rate. * If electricity is not needed‚ the sluice gates can be shut‚ stopping electricity generation. The water can be saved for use another time when electricity demand is high. * Dams are designed to last many decades and so can contribute to the generation of electricity for many years / decades. * The lake that forms behind the dam can be used for water sports and leisure /

Groundwater dams are structures that intercept or obstruct the natural flow of groundwater and provide storage for water underground. They have been used in several parts of the world‚ notably India‚ Africa and Brazil. Their use is in areas where flows of groundwater vary considerably during the course of the year‚ from very high flows following rain to negligible flows during the dry season. The basic principle of the groundwater dam is that instead of storing the water in surface reservoirs‚ water
