-
Reduced greenhouse gas emissions
-
Increased energy independence
-
Lower energy costs
-
Increased energy consumption
D
Correct answer
Explanation
Energy efficiency aims to reduce energy consumption, not increase it.
Which of the following is NOT a type of energy-efficient lighting technology?
-
Compact fluorescent lamps (CFLs)
-
Light-emitting diodes (LEDs)
-
Incandescent light bulbs
-
Halogen lamps
C

Which of the following is NOT a benefit of energy conservation?
-
Reduced energy consumption
-
Lower energy costs
-
Increased energy independence
-
Increased greenhouse gas emissions
D
Correct answer
Explanation
Energy conservation does not produce greenhouse gases, so it does not contribute to increased greenhouse gas emissions.
What is the primary purpose of an Energy Star label on an appliance?
-
Indicates compliance with safety standards
-
Certifies energy efficiency
-
Enhances product durability
-
Promotes brand recognition
B
Correct answer
Explanation
