Which type of wave energy converter utilizes a ramp-like structure that allows waves to flow over it?
-
Oscillating Water Column
-
Overtopping Device
-
Pelamis
-
Wave Dragon
B
Correct answer
Explanation
An overtopping device is a type of wave energy converter that utilizes a ramp-like structure that allows waves to flow over it, capturing the energy of the water as it falls back down.
Which type of wave energy converter utilizes a series of turbines that rotate as waves pass through them?
-
Oscillating Water Column
-
Overtopping Device
-
Pelamis
-
Wave Rotor
D
Correct answer
Explanation
The Wave Rotor is a type of wave energy converter that utilizes a series of turbines that rotate as waves pass through them, generating electricity.

-
Overtopping Device
-
Pelamis
-
PowerBuoy
D
Correct answer
Explanation
The PowerBuoy is a type of wave energy converter that utilizes a floating platform that moves with the waves, generating electricity through a direct drive system.
Which of the following is a renewable energy source that does not contribute to greenhouse gas emissions?
-
Solar Energy
-
Wind Energy
-
Hydropower
-
Natural Gas
Correct answer
Explanation
Solar Energy, Wind Energy, and Hydropower are all renewable energy sources that do not contribute to greenhouse gas emissions during electricity generation.
Which of the following is NOT a major source of energy supply globally?
-
Fossil fuels (oil, gas, coal)
-
Renewable energy (solar, wind, hydro)
-
Nuclear energy
-
Biomass energy
D
Correct answer
Explanation
Biomass energy, while a renewable source, is not a major source of energy supply globally compared to fossil fuels, renewable energy, and nuclear energy. Fossil fuels still dominate the global energy mix, accounting for the majority of energy production and consumption.
What is the term used to describe the situation where energy is produced and consumed locally, reducing the need for long-distance transmission?
-
Distributed energy generation
-
Decentralized energy production
-
Local energy production
-
All of the above
D
Correct answer
Explanation
Distributed energy generation, decentralized energy production, and local energy production all refer to the concept of generating energy close to the point of consumption, reducing the need for long-distance transmission.
