What is HydroPower Energy? Hydropower (Hydroelectric power) system convert the kinetic energy in flowing water into electric energy. Hydropower is renewable source of energy since water is available in large quantities from rain, rivers and oceans. Hydropower or hydroelectric energy is generated when falling water is channelled through water turbine. Hydropower energy usually produced by dams, because dams can store and direct large volumes of water.

Hydropower Energy Advantages Its a renewable energy It decreases the effect of greenhouse gases such as carbon dioxide. It control the risk of flood. Clean and cheap energy. Disadvantages Dirt can build up at dams and decreasing their effectiveness. Very expensive to build. Dam construction forces people to leave their home if they live in or near the flooded river valley. Reduces areas for certain types of recreation such as fishing, camping, hunting and hiking.

Dam Barriers which confines or raise water for storage to create a hydraulic head. Made of concrete. PURPOSE : 1. To store the water and regulate the outgoing flow of water. 2. Enable energy storage in the reservoir 3. Helps to increase the head of the water. 4. Ensure a steady supply of water to the system without fluctuation

Water reservoirs PURPOSE : 1. To store water which is further utilized to generate power by running the hydroelectric turbine. •. In the reservoir the water collected from catchment area is stored behind a dam. •. Catchment area gets its water from rain and stream. •. The level of water surface in the reservoir = head water level.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
