Which of the following is a disadvantage of constructing hydroelectric dams?
Hydropower has the ability to generate electricity without emitting greenhouse gasses. However, it can also cause environmental and social threats, such as damaged wildlife habitat, harmed water quality, obstructed fish migration, and diminished recreational benefits of rivers.
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 a major disadvantage of large dams?
Disadvantages of Dams Reservoirs often emit a high percentage of greenhouse gases. Often disrupts local ecosystems. It disrupts the groundwater table. Blocks progression of water to other countries, states or regions.
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.
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.
How does hydropower affect wildlife?
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.
What are three disadvantages of geothermal energy?
- Environmental issues. There is an abundance of greenhouse gases below the surface of the earth. …
- Surface instability (earthquakes) Construction of geothermal power plants can affect the stability of land. …
- Expensive. …
- Location-specific. …
- Sustainability issues.
What are the negative effects of geothermal energy?
Air and water pollution are two leading environmental issues associated with geothermal energy technologies. Additional concerns are the safe disposal of hazardous waste, siting and land subsidence. Most geothermal power plants require a large amount of water for cooling or other purposes.
What are the disadvantages of using solar energy?
- Cost. The initial cost of purchasing a solar system is fairly high. …
- Weather-Dependent. Although solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops. …
- Solar Energy Storage Is Expensive. …
- Uses a Lot of Space. …
- Associated with Pollution.
What are negative effects of dams?
Dams store water, provide renewable energy and prevent floods. Unfortunately, they also worsen the impact of climate change. They release greenhouse gases, destroy carbon sinks in wetlands and oceans, deprive ecosystems of nutrients, destroy habitats, increase sea levels, waste water and displace poor communities.
