1. Which material is commonly used for insulation in buildings to
reduce heat loss?
A. Wood
B. Concrete
C. Fiberglass
D. Steel
Answer: c) Fiberglass
Rationale: Fiberglass is a widely used insulating material that reduces
heat loss and improves the energy efficiency of buildings.
2. What is the primary challenge in storing renewable energy?
A. It is expensive to build storage systems
B. Renewable energy is unpredictable and intermittent
C. It generates too much waste
D. There is too much supply
Answer: b) Renewable energy is unpredictable and intermittent
Rationale: The main challenge is that renewable energy sources like
solar and wind are variable and not available 24/7, making energy
storage crucial for ensuring a steady supply.
,3. Which of the following is the main disadvantage of using natural
gas?
A. It is difficult to transport
B. It is a non-renewable energy source
C. It generates too much heat
D. It requires high levels of technology
Answer: b) It is a non-renewable energy source
Rationale: Natural gas is a non-renewable fossil fuel, meaning it is finite
and contributes to the depletion of natural resources over time.
4. Which of the following is an example of an energy storage system?
A. Solar panels
B. Wind turbines
C. Battery storage
D. Geothermal heating
Answer: c) Battery storage
Rationale: Battery storage systems store excess energy generated
during low demand periods for later use, helping balance supply and
demand.
5. What is the key environmental issue associated with fracking for
natural gas?
A. It generates large amounts of waste
, B. It causes water contamination and habitat disruption
C. It produces more greenhouse gases than coal
D. It uses large amounts of renewable resources
Answer: b) It causes water contamination and habitat disruption
Rationale: Fracking can lead to water contamination and disrupt local
ecosystems due to the chemicals used in the process and the
infrastructure involved.
6. What is the principle behind the operation of a tidal power station?
A. The conversion of sunlight into electricity
B. The use of the movement of ocean water to generate energy
C. The use of geothermal heat to generate electricity
D. The conversion of wind energy into mechanical energy
Answer: b) The use of the movement of ocean water to generate energy
Rationale: Tidal power stations harness the energy of rising and falling
tides to generate electricity, making use of the movement of water.
7. Which energy source is typically used in combined heat and power
(CHP) systems?
A. Solar energy
B. Biomass
C. Wind energy
D. Geothermal energy
