Answer 1

An impact that is not associated with the use of hydroelectric energy is the;

A. Release of contaminants

When you produce hydroelectric energy, you're disrupting the water flow by building dams and power-plants.

This also disrupts the aquatic wildlife that inhabits certain areas.

Answer 2

Option A, release of contaminants

Step-by-step explanation:

Hydroelectric energy is harnessed from water by constructing dam and other engineering structures to store water and then allowing it to fall from great heights which in turn rotate the turbines to generate electricity . The huge amount of water stored in dams come from natural flowing rivers or streams. When flowing river is diverted from its original path of flow or is made to slow down for water storage, huge friction occurs at its bed and side slopes which causes erosion . The natural navigation process of the fish/other aquatic animals in it also gets affected. There is no release of contaminants as hydroelectric energy is a clean and sustainable source of energy.
