Perhaps the largest disadvantage of hydroelectric energy is the impact it can have on the environment. When water rushes through a dam and its internal turbines it can create a great spot for sediment layers to be trapped and congregate which then can pollute the water and disrupt the ecology. Which of the following is a drawback to the use of hydropower.

Require high-quality material for construction of dam. It disrupts the groundwater table. Hydropower consumes more fossil fuels than power plants fueled solely by fossil fuels.

Sediment buildup Extensive irrigation may contribute to desertification because evaporation of water used in irrigation causes salinization of the land reducing the ability of plants to grow.
