1. What is the concept of “energy autonomy” in a building?
A. Using as much energy as possible
B. Generating energy from renewable sources on-site
C. Relying on fossil fuels for energy
D. Using energy from the national grid
Answer: b) Generating energy from renewable sources on-site
Rationale: Energy autonomy refers to a building generating its own
energy, typically through solar panels or wind turbines, to meet its
energy needs without relying on external sources.
2. Which of the following is an example of passive solar heating?
A. Solar water heaters
B. Solar panels
C. Using south-facing windows to capture sunlight
D. Wind turbines
Answer: c) Using south-facing windows to capture sunlight
Rationale: Passive solar heating uses natural methods, like orienting
buildings to capture sunlight through windows, without mechanical
devices.
3. What is the role of an inverter in a photovoltaic (PV) solar system?
,A. To store energy for later use
B. To convert solar energy into heat
C. To convert direct current (DC) electricity to alternating current
(AC)
D. To increase the voltage of electricity
Answer: c) To convert direct current (DC) electricity to alternating
current (AC)
Rationale: Inverters are used in PV solar systems to convert the DC
electricity generated by solar panels into AC electricity, which can be
used in homes and businesses.
4. 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.
5. Which of the following can help reduce energy consumption in
industrial facilities?
, A. Increasing production time
B. Upgrading to energy-efficient machinery
C. Reducing the number of workers
D. Using more fossil fuels
Answer: b) Upgrading to energy-efficient machinery
Rationale: Replacing outdated machinery with energy-efficient
equipment helps reduce energy consumption and improves operational
efficiency.
6. Which energy source has the least environmental impact?
A. Coal
B. Natural gas
C. Solar energy
D. Nuclear energy
Answer: c) Solar energy
Rationale: Solar energy has the least environmental impact, as it
produces no greenhouse gases or pollutants during operation and is
renewable.
7. How does LED lighting compare to traditional incandescent bulbs in
terms of energy efficiency?
A. LEDs consume more energy
B. LEDs consume less energy and last longer
A. Using as much energy as possible
B. Generating energy from renewable sources on-site
C. Relying on fossil fuels for energy
D. Using energy from the national grid
Answer: b) Generating energy from renewable sources on-site
