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.
Nuclear plants, on the other hand, have three significant nuclear energy cons or problems. The first of these nuclear energy disadvantages is although they are relatively cheap to run, they are extremely expensive to build.At construction costs of up to $4400 per kilowatt-hour, they are extremely expensive to buildâalmost 9 billion dollars for a 2000 megawatt hour plant. Lots of technological advances still to be made will increase efficiency, safety. 2  Small amount of fuel can produce a huge amount of energy. 3  Nuclear fission could solve a lot of the disadvantages. 4  Low emissions source of reliable and constant power generation.
