Which is the greatest negative effect of obtaining hydroelectric power *?
There also some *cons* when it comes to hydropower:
There are numerous environmental consequences of damming water, flooding entire areas, creating massive reservoirs, changing water flow, blocking the natural course of rivers, and constructing power lines and roads.
Which of the following negative consequences is most often associated with using biomass for energy production?
Can lead to deforestation. Since wood is one of the most used source of biomass energy, vast amounts of wood and other waste products have to be burned to produce the desired amount of power. While currently there is enough wood waste already, there is a risk of deforestation in the future.
Why hydroelectric power is bad?
Hydropower can impact water quality and flow. Hydropower plants can cause low dissolved oxygen levels in the water, a problem that is harmful to riparian (riverbank) habitats and is addressed using various aeration techniques, which oxygenate the water.
What are the advantages and disadvantages of hydropower plant?
Advantages of Hydroelectricity: It is a clean and non-polluting source of energy. No fuel is required.
Disadvantages of Hydroelectricity:
- Highly expensive.
- Large areas of human habitation and agricultural fields are submerged.
- Dams can be made in limited areas.
Why are hydroelectric dams bad?
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.
What are the pros of hydroelectric power?
Hydropower provides benefits beyond electricity generation by providing flood control, irrigation support, and clean drinking water. Hydropower is affordable. Hydropower provides low-cost electricity and durability over time compared to other sources of energy.
What are the benefits of hydroelectricity?
AND RENEWABLE. Hydropower draws energy from falling or flowing water and converts it into electricity, without consuming, wasting or depleting water in the process. Hydropower produces no air pollutants and has ultra-low greenhouse gas emissions.
What are the pros and cons of geothermal?
An Overview of Geothermal Pros and Cons:
|This energy source is more environmentally friendly than conventional fuel sources.||The largest single disadvantage of geothermal energy is that it is location specific.|
|A source of renewable energy.||Gases are released into the atmosphere during digging.|
