Energy Efficiency and Green Buildings Questions

Multiple choice

Which of the following is a best practice for reducing air pollution from industrial facilities?

  1. Use cleaner production processes

  2. Install air pollution control technologies

  3. Improve energy efficiency

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All of the options listed are best practices for reducing air pollution from industrial facilities. Using cleaner production processes reduces the amount of pollutants that are generated in the first place. Installing air pollution control technologies, such as electrostatic precipitators and FGD systems, removes pollutants from the air before they are released into the atmosphere. Improving energy efficiency reduces the amount of fuel that is needed to operate the facility, which also reduces air pollution.
