The sentence that describes a way hydroelectric plants are better than other power plants is option D. This is because, it details why hydroelectric plants are more efficient at providing peak power demands during shorter periods than fossil fuels and nuclear power plants.
Why is hydroelectricity the best?
Hydropower produces no air pollutants and has ultra-low greenhouse gas emissions. … Converting over 90% of available energy into electricity, hydropower is the most efficient source of electrical energy. By comparison, the best fossil fuel power plants operate at approximately 60% efficiency.
How are hydroelectric plants like other power plants?
A coal–fired power plant uses steam to turn the turbine blades; whereas a hydroelectric plant uses falling water to turn the turbine.
How would you describe a hydroelectric power plant?
The most common type of hydroelectric power plant is an impoundment facility. An impoundment facility, typically a large hydropower system, uses a dam to store river water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
Is hydroelectric power plant good or bad?
Hydropower and 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.
What are 5 advantages of hydropower?
Advantages of hydroelectric energy
- Renewable. Hydroelectric energy is classified as a renewable energy source because it is powered by water, and water is a naturally replenishing resource. …

What are the 3 main components of hydroelectric power plant?
A typical hydroelectric plant is a system with three parts: a power plant where the electricity is produced, a dam that can be opened or closed to control water flow, and a reservoir where water is stored. The water behind the dam flows through an intake and pushes against blades in a turbine, causing them to turn.
Why is there little to no growth expected for hydropower?
Why is there little to no growth expected for hydropower? Hydropower uses a nonrenewable resource that is quickly being depleted. The cost of generating power is much too high. … Almost all rivers that can be dammed for power generation have been dammed already.
What are the advantages and disadvantages of hydroelectric power 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.
Where is hydroelectricity used?
They include natural gas, oil, coal, nuclear power, biomass, solar and wind power, and water. Over the years, hydropower has been the leading source of electricity in Canada, and its predominance continues today. More than 70,000 MW of hydropower have already been developed in Canada.
How do we get hydroelectric power?
The most common type of hydroelectric power plant uses a dam on a river to store water in a reservoir. Water released from the reservoir flows through a turbine, spinning it, which in turn activates a generator to produce electricity.
Which is better hydropower or nuclear?
Hydroelectric power has many advantages: it produces very little pollution; it is affordable; and the plants are energy-efficient, require little maintenance and are easy to stop and start. Besides being inexpensive, nuclear power produces little air pollution or greenhouse gases and can be contained in a small space.
Does hydropower release greenhouse gases?
While hydropower is a potentially clean source of renewable energy, some projects produce high greenhouse gas (GHG) emissions per unit electricity generated (carbon intensity).
