DISADVANATGES: 1. Dams are extremely expensive to build and must be built to a very high standard. 2. The high cost of dam construction means that they must operate for many decades to become profitable. 3. The flooding of large areas of land means that the natural environment is destroyed. 4. People living in villages and towns that are in the valley to be flooded‚ must move out. This means that they lose their farms and businesses. In some countries‚ people are forcibly removed so that

Hydroelectric The Hoover Dam does more than attract tourist‚ it provides power to 8 million people (32). Instead of using a heat source to create steam to turn a turbine like most power plants‚ hydroelectric plants use the natural flow of water and divert it through a turbine via a dam. The estimated available hydro energy in the United States‚ discounting wilderness preserves and the likes‚ is 65 gigawatts. One significant advantage of hydroelectric power in the U.S. is that there are existing

INTRODUCTION In hydroelectric power plant‚ turbine been used to generate power from reservoir of water. Turbine been selected by their characteristic curves based on the potential energy available in the water and the amount of power to be generated. Turbine is a type that develops torque by reacting to the pressure or weight of a fluid. The operation of reaction turbine can be describes by the Newton’s third law of motion that is for every action‚ there is an equal and opposite reaction. In this
