Question

which behavior can reduce pollution that occurs due to the burning of coal?
a. install a second refrigerator in the hot garage.
b. replace a conventional car with an electric car.
c. use ceiling fans and reduce air conditioning use in summer.
d. support the construction of new coal - based power plants.

Explanation:

• Option A: Installing a second refrigerator in the hot garage would increase energy consumption (as the refrigerator would have to work harder in a hot environment), which in turn would likely increase the demand for electricity (often generated from coal - fired power plants in many regions), thus increasing coal - burning pollution.
• Option B: Replacing a conventional car with an electric car mainly reduces pollution from gasoline combustion (e.g., carbon monoxide, unburned hydrocarbons). While the electricity to charge the car might come from various sources (including coal - fired power plants in some cases), this option is not directly related to reducing coal - burning pollution compared to other options.
• Option C: Using ceiling fans and reducing air - conditioning use in summer reduces electricity consumption. Since a significant portion of electricity in many areas is generated by burning coal, reducing electricity use directly reduces the amount of coal that needs to be burned for power generation, thereby reducing coal - burning pollution.
• Option D: Supporting the construction of new coal - based power plants would increase the capacity for coal - burning, leading to more coal - burning pollution.

Answer:

C. Use ceiling fans and reduce air conditioning use in summer.
