Energy Resources and Storage Questions
Which of the following is an example of a non-renewable energy source?
-
Coal
-
Natural gas
-
Solar energy
-
Wind energy
A
Correct answer
Explanation
Coal is a non-renewable energy source, as it is derived from fossil fuels that are formed over millions of years and cannot be replenished.
Which of the following is NOT a type of marine renewable energy technology?
-
Tidal energy
-
Wave energy
-
Current energy
-
Solar energy
D
Correct answer
Explanation
Solar energy is not a marine renewable energy technology because it does not harness energy from the ocean.
Which type of tidal energy technology uses a barrage to create a difference in water level?
-
Tidal stream turbines
-
Tidal barrages
-
Tidal lagoons
-
Dynamic tidal power
B
Correct answer
Explanation
Tidal barrages are tidal energy technologies that use a barrage to create a difference in water level between two bodies of water, which is then used to generate electricity.
Which type of wave energy technology uses a floating buoy to generate electricity?
-
Oscillating water column
-
Overtopping device
-
Pelamis wave energy converter
-
Wave dragon
C
Correct answer
Explanation
The Pelamis wave energy converter is a type of wave energy technology that uses a floating buoy to generate electricity. The buoy is connected to a hydraulic system that drives a generator.
Which type of current energy technology uses a horizontal axis turbine to generate electricity?
-
Horizontal axis turbine
-
Vertical axis turbine
-
Cross-flow turbine
-
Darrieus turbine
A
Correct answer
Explanation
Horizontal axis turbines are the most common type of current energy technology. They use a horizontal axis turbine to generate electricity, similar to wind turbines.
Which marine renewable energy technology has the lowest environmental impact?
-
Tidal energy
-
Wave energy
-
Current energy
-
Ocean thermal energy conversion
A
Correct answer
Explanation
Tidal energy has the lowest environmental impact among marine renewable energy technologies because it does not require the construction of large structures in the ocean.
What is the potential of marine renewable energy to contribute to the global energy mix?
-
Up to 10%
-
Up to 20%
-
Up to 30%
-
Up to 40%
B
Correct answer
Explanation
The potential of marine renewable energy to contribute to the global energy mix is estimated to be up to 20%.
Which marine renewable energy technology is still in the early stages of development?
-
Tidal energy
-
Wave energy
-
Current energy
-
Ocean thermal energy conversion
D
Correct answer
Explanation
Ocean thermal energy conversion is still in the early stages of development, as it requires large temperature differences between the ocean surface and the deep ocean.
Which of the following is NOT a potential application of nanomaterials in the field of energy?
-
Solar cells
-
Batteries
-
Fuel cells
-
Nuclear reactors
D
Correct answer
Explanation
Nuclear reactors are not directly related to the applications of nanomaterials in the field of energy. Solar cells, batteries, and fuel cells are all examples of technologies where nanomaterials can be used to improve efficiency, reduce costs, and enhance performance.
What is the primary source of energy for solar energy technologies?
-
Wind
-
Water
-
Sunlight
-
Fossil Fuels
C
Correct answer
Explanation
Solar energy technologies utilize the energy from sunlight to generate electricity or heat.

What is the term used to describe the situation where the demand for energy exceeds the supply?
-
Energy crisis
-
Energy shortage
-
Energy gap
-
All of the above
D
Correct answer
Explanation
An energy crisis, energy shortage, or energy gap all refer to the situation where the demand for energy exceeds the supply, leading to higher prices and potential disruptions in energy services.
Which of the following is a renewable energy source?
-
Fossil fuels
-
Nuclear energy
-
Solar energy
-
Hydropower
C
Correct answer
Explanation

What is the term used to describe the situation where the supply of energy exceeds the demand?
-
Energy surplus
-
Energy glut
-
Energy oversupply
-
All of the above
D
Correct answer
Explanation
Energy surplus, energy glut, and energy oversupply all refer to the situation where the supply of energy exceeds the demand, leading to lower prices and potential disruptions in energy markets.
