You can go green and slash your heating and cooling bills by doing all of these except:
- A.
Growing grapevines on trellises
- B.
Adding a bounty of rock to the south side of your yard
- C.
Growing trees in your yard
- D.
Growing shrubs to shade your air conditioning unit
Correct Answer
B. Adding a bounty of rock to the south side of your yardExplanation
Unshaded rock, cement, and asphalt landscaping can radiate heat and raise the temperatures around your house. Instead, plant trees, vines, and shrubs to promote greenery and cut your energy bills. Just three deciduous trees on the south and west sides can have a cooling effect in summer, and a warming effect in winter. Also, evergreen trees on the north side of your house act as windbreakers in the winter and will help to lower your heating bills. Visit the U.S. Department of Energy website to find out more about landscaping for energy-efficiency.Rate this question:

Which of these small changes can go a long way toward preventing air pollution?
- A.
Using water-based paints instead of oil-based paints
- B.
Refueling your car after dark
- C.
Limiting dry cleaning
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
Paints, dry cleaning solvents, and gas, all contain toxic air pollutants like volatile organic compounds (VOCs) which when released into the air can have hazardous effects on your health and environment. Some ways to reduce air pollution include: choosing water-based paints with lower VOCs, making sure to recycle or reuse any leftover paint (all paint contains hazardous substances and should be handled carefully), and limiting your dry cleaning. Also, refueling after dark helps reduce the chance of VOCs combining with sunlight to create ground-level ozone.Rate this question:
