  • Expensive. …
  • Droughts. …
  • Limited Reservoirs.

What are the negative effects of hydroelectric dams?

Hydropower dams degrade water quality along rivers. Water that flows downstream from the dams is depleted of oxygen which harms many aquatic animals. The reservoirs above dams are susceptible to harmful algal blooms and can leach toxic metals such as mercury from submerged soil.

How is hydropower bad for the environment?

Hydropower does not pollute the water or the air. However hydropower facilities can have large environmental impacts by changing the environment and affecting land use homes and natural habitats in the dam area. … Operating a hydroelectric power plant may also change the water temperature and the river’s flow.

Which of the following is a disadvantage of most of the renewable energy sources?

The correct answer is option (B) Unreliable supply. The major disadvantage of renewable energy sources is the unreliable supply.

Which of the following is not a part of hydroelectric power plant?

Explanation: Sedimentation is not a constituent of a hydro power plant. Usually a dam water reservoir intake and control gates water turbines and penstack are some of the components that are used in major parts of a hydro electric power plant.

What are advantages of hydroelectricity?

In particular carbon dioxide (CO2) emissions are reduced by 670 grams for each kW/h of energy output. Other advantages are: a low dependence on ester energy sources source diversification and the regional re-organization of energy production.

What is the disadvantages of biomass?

One of the disadvantages of biomass energy is the amount of space that it requires. … Another disadvantage is that biomass energy is not entirely clean. Some greenhouse gases are still produced although the levels of these gases are far less than those produced by fossil fuels.

What is the limitations for use of biomass energy?

What is the disadvantage of biogas?

An unfortunate disadvantage of biogas today is that the systems used in the production of biogas are not efficient. There are no new technologies yet to simplify the process and make it accessible and low cost. This means large scale production to supply for a large population is still not possible.

How does hydropower affect fish?

While dams can provide flood protection energy supply and water security they also pose a significant threat to freshwater species. Dams block fish from moving along their natural pathways between feeding and spawning grounds causing interruptions in their life cycles that limit their abilities to reproduce.

How does hydroelectric affect our air?

Hydropower generators do not directly emit air pollutants. However dams reservoirs and the operation of hydroelectric generators can affect the environment. A dam that creates a reservoir (or a dam that diverts water to a run-of-river hydropower plant) may obstruct fish migration.

How does hydropower affect society?

The results of our social literature review discuss the major positive and negative social impacts of hydroelectric development. Social benefits are primarily economic growth and improved flood control while negative social impacts are displacement adverse effects to human health and livelihood changes.

What are the negative effects on the environment when building a large hydroelectric dam?

Flooding land for a hydroelectric reservoir has an extreme environmental impact: it destroys forest wildlife habitat agricultural land and scenic lands. In many instances such as the Three Gorges Dam in China entire communities have also had to be relocated to make way for reservoirs [3].

Which of the following is not a renewable source of energy?

Coal fossil fuels crude oil natural gas etc are all hydrocarbon fuels. These are non-renewable source of energy.

Which among these is not a renewable source of energy?

Coal is a non – renewable source of energy. It takes thousands of years to form coal in nature. Additional information: Coal and petroleum are fossil fuels.
