Question

question 27 of 29 which behavior can reduce pollution that occurs due to the use of coal? a. support the construction of new coal - based power plants. b. install a second refrigerator in the hot garage. c. replace a conventional car with an electric car. d. replace old appliances with energy - efficient ones.

Explanation:

Coal - based power plants use coal and produce pollution. Adding more (A) is not helpful. Installing a second refrigerator (B) increases energy consumption and may lead to more coal - fired power usage for electricity generation. Replacing a conventional car with an electric car (C) mainly reduces pollution from gasoline, not directly related to coal - use pollution. Replacing old appliances with energy - efficient ones (D) reduces overall electricity demand. Since a significant portion of electricity is generated from coal, this reduces the need for coal - fired power generation and thus coal - related pollution.

Answer:

D. Replace old appliances with energy - efficient ones.
