Energy Resources and Storage Questions

Multiple choice

Which type of hydropower plant uses a dam to create a reservoir of water?

  1. Run-of-the-river

  2. Pumped-storage

  3. Impoundment

  4. Tidal
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Impoundment hydropower plants store water behind a dam, creating a reservoir, and release it through turbines to generate electricity.

Multiple choice

Which type of hydropower plant utilizes the natural rise and fall of tides to generate electricity?

  1. Run-of-the-river

  2. Pumped-storage

  3. Impoundment

  4. Tidal
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Tidal hydropower plants use the energy of the tides to generate electricity by capturing the incoming and outgoing tides in a basin or reservoir.

Multiple choice

What is the term used to describe the maximum amount of power that a hydropower plant can generate?

  1. Installed Capacity

  2. Peak Demand

  3. Base Load

  4. Capacity Factor
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Installed capacity refers to the maximum amount of electrical power that a hydropower plant can generate under ideal conditions.

Multiple choice

What is the term used to describe the ratio of the actual energy output of a hydropower plant to its theoretical maximum energy output?

  1. Efficiency

  2. Capacity Factor

  3. Utilization Factor

  4. Load Factor
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Capacity factor is the ratio of the actual energy output of a hydropower plant over a period of time to its theoretical maximum energy output during that same period.

Multiple choice

Which type of hydropower plant utilizes the kinetic energy of flowing water without the need for a dam?

  1. Run-of-the-river

  2. Pumped-storage

  3. Impoundment

  4. Tidal
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Run-of-the-river hydropower plants utilize the natural flow of a river without the need for a dam, capturing the kinetic energy of the flowing water to generate electricity.

Multiple choice

What is the term used to describe the process of using excess electricity from the grid to pump water from a lower reservoir to a higher reservoir in a pumped-storage hydropower plant?

  1. Pumping

  2. Turbining

  3. Diversion

  4. Condensation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Pumping in a pumped-storage hydropower plant involves using excess electricity from the grid during off-peak hours to pump water from a lower reservoir to a higher reservoir, storing potential energy for later use during peak demand periods.

Multiple choice

Which of the following is NOT a primary source of energy?

  1. Solar

  2. Wind

  3. Natural Gas

  4. Hydropower
Reveal answer Fill a bubble to check yourself
