Please enumerate the the advantages and disadvantages of hydroelectric power………..?
hi there, disadvantages:: The dams are very expensive to build. However, many dams are also used for flood control , so building costs can be shared. Building a large dam will flood a very large area upstream, causing problems for fish,etc, that used to live there. Finding a suitable site can be difficult – the impact on residents and the environment may be unacceptable. Water quality and quantity downstream can be affected, which can have an impact on plant life. advantages: Once the dam is built, the energy is virtually free. No waste or pollution produced. Much more reliable than wind, solar or wave power. Water can be stored above the dam ready to cope with peaks in demand. Hydro-electric power stations can increase to full power very quickly, unlike other power stations. Electricity can be generated constantly.
