Multiple choice

Which of the following is a strategy for reducing air pollution from residential sources?

  1. Using energy-efficient appliances

  2. Improving home insulation

  3. Using renewable energy sources

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Using energy-efficient appliances, improving home insulation, and using renewable energy sources are all strategies for reducing air pollution from residential sources. Energy-efficient appliances consume less energy, which reduces the amount of pollutants emitted by power plants. Improving home insulation reduces the amount of energy needed to heat and cool a home, which also reduces air pollution. Using renewable energy sources, such as solar energy and wind energy, does not produce air pollution.
