In one of the previous articles, we learned Top 10 advantages of Hydroelectric power stations. Alongside numerous advantages, there are a couple of disadvantages associated with hydroelectric power generation. Given below is a list of these disadvantages.
- Forests are submerged and the ecosystem is badly damaged, the case is more evident when the dam reservoirs are larger in size
- Waterborne diseases also increase around stagnant water reservoirs
- Dam bursting can cause a flood and immense damage to the lives and nearby properties
- Countries suffering from long drought periods have an insufficient amount of water available for driving turbines
- Huge capital cost should be invested for designing dams
- The long time required for building
- Requires large investment on transmission systems
- Requires technically trained and experienced workers for designing DAMs
- The average age of a DAM is around 50 years, for earning profit out of given investment and keeping depreciation rate in mind, the price per unit goes high
- Taxation is imposed on the public for construction of government-owned dams
