Answer

Hydropower is renewable source of energy because water gets refilled in reservoir during raining.
High-rise dams are constructed to generate hydroelectricity.
Such dams are constructed in hilly areas causing environmental changes.
Large eco-systems are submerged under water and destroyed.
The submerged vegetation decaying anaerobically releases large amount of greenhouse gas, i.e., methane.
Large areas of agricultural land is also submerged. Many natives are thus displaced.
Rural-tribal human races may lose their habitat.
So, Hydropower plant construction creates certain problems.
