Which of the following is disadvantage of hydropower?
dams can be constructed only in limited areas. large areas of land get submerged within water when dams are erected. submerged vegetation rots under anaerobic conditions and produce methane a green house gas.
Why hydropower is bad?
Just as reducing downstream water flow can cause a loss of habitat creating reservoirs to generate electricity in storage and pumped storage hydropower systems often cause upstream flooding that destroys wildlife habitats scenic areas and prime farming land.

Which of the following is not a disadvantage of hydropower?
Which of the following is not an advantage of hydroelectric power plant? Explanation: Output of such plants is never constant. This is because of their dependency over flow rate of water in river which is seasonal. No fuel requirement low running cost and no standby losses are advantages of hydroelectric power plants.
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.
What are 2 disadvantages of biomass?
- Biomass energy is not as efficient as fossil fuels. Some biofuels like Ethanol is relatively inefficient as compared to gasoline. …
- It is not entirely clean. …
- Can lead to deforestation. …
- Biomass plants require a lot of space.
What are the advantages and disadvantages of small hydropower plants?
- Efficient energy source. …
- Reliable electricity source. …
- No reservoir required. …
- Cost effective energy solution. …
- Power for developing countries. …
- Integrate with the local power grid. …
- Suitable site characteristics required. …
- Energy expansion not possible.
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.
How does hydropower affect fish?
How does hydroelectricity affect humans?
The study warns that the chemical’s impact increases cardiovascular risks and children with high prenatal exposure will suffer from attention deficit and hyperactivity disorder problems.
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].
What are the advantages and disadvantages of hydropower plant Class 10?
…
Disadvantages of Hydroelectricity:
- Highly expensive.
- Large areas of human habitation and agricultural fields are submerged.
- Dams can be made in limited areas.
What are the disadvantages of water?
Here are some disadvantages of drinking too much water:
It is said that too much consumption of water can lead to fluid overload in the body and imbalance in the body. Excess water can lead to lower sodium levels in the body which may further lead to nausea vomiting cramps fatigue et al.
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.
Which statement about surge tank is wrong?
Which statement about surge tank is wrong? Explanation: Function of surge tank is to relieve the penstock from excessive water hammer pressure. It does so by receiving rejected flow of water into the tank. A totally closed tank can not release pressure so usually surge tanks are left open at the top.
What is the biggest nuclear power plant in India?
Kudankulam Nuclear Power Plant
Kudankulam Nuclear Power Plant in Tamil Nadu is the highest capacity nuclear plant in India with an installed capacity of 2000 MW.Oct 19 2021
How does hydroelectric affect our water?
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.
What are the effects of hydroelectricity?
In addition to methane hydropower can have significant environmental effects such as fish injury and impact on downstream water quality. By diverting water out of the water bodies for power dams remove water needed for healthy in-stream ecosystems thereby disrupting the natural river flows.
What are 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 are the disadvantages and advantages of biomass?
| Advantages of Biomass Energy | Disadvantages of Biomass Energy |
|---|---|
| It is Renewable | It’s Not Completely Clean |
| Carbon Neutrality | High Costs In Comparison To Other Alternatives |
| Less Dependency On Fossil Fuels | Possible Deforestation |
| It Is Versatile | Space |
What is the disadvantage of biogas?
Which among the following is not a renewable sources 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.
Which among the following is not a renewable source of energy Mcq?
Explanation: Amongst all the resources mentioned Coal is a non-renewable resource.
Which among these is not a renewable source of energy?
Coal petroleum natural gas etc. are some of the resources of energy which do not get replenished as frequently as they are consumed and hence their use has to be regulated and limited and is classified under non-renewable resources.
How do hydroelectric dams affect animals?
Hydroelectric dams block migrating fish from getting to their spawning grounds. Hydroelectric dams damage native river ecosystems by changing the physical chemical and biological properties of the river and are therefore not a good solution to our energy crisis.
Why are dams bad for fish?
Dams can block or impede migration and have created deep pools of water that in some cases have inundated important spawning habitat or blocked access to it. … Low water velocities in large reservoirs also can delay salmon migration and expose fish to high water temperatures and disease.
Why is hydropower not renewable?
How does hydropower affect the economy?
Why hydropower is not clean energy?
Many countries consider hydroelectricity a clean source of power because it doesn’t involve burning dirty fossil fuels. But that’s far from true. Hydropower is a significant source of greenhouse gas emissions: a new study shows that the world’s hydroelectric dams are responsible for as much methane emissions as Canada.
What is the negative effect of dams?
