The disadvantages are that the change in water flow will effect the fish and making space to put the hydro facility can cause the deaths of plants and animals aswell as destruction of habitat. Hydroelectiric facilities do not produce much electricity compared to other renewable sources.

Dams are a very common source of hydroelectric power in BC.
At independence, in 1947, there were fewer than 300 large dams in India. By the year 2000 the number had grown to over 4000, more than half of them built between 1971 and 1989. India ranks third in the world in dam building, after US and China. While some of these dams were built primarily for flood control, water supply, and hydroelectric power generation, the primary purpose of most Indian dams remains irrigation.
