Disadvantages of hydroelectric power. There are many disadvantages of hydroelectric power due to which it is not used on a very large scale all around the globe. Before employing something on an industrial level, you should consider pros and cons of hydropower.So the disadvantages are:he reservoir of water for hydroelectric power releases a large amount of carbon dioxide and methane. The area around the dam is filled with water. The plants and trees in them start rotting and decompose by other method without the use of oxygen.
Hydroelectric power is a major electricity source in Ontario and the largest source in Canada overall. Most electricity in Canada is derived from large-capacity hydroelectric plants with dams, which have a more serious environmental and social impact than do small-capacity plants.ams are used for large capacity hydroelectric plants, while run-of-river systems have small plants with a very minor dam or none at all. The run-of-river system diverts some of the water in a river into a canal that sends the water through turbines at a small generation station.
