1.   c. 25 billion:  According to the EPA, replacing these electronic devices with ENERGY STAR models, would save over 25 billion pounds of greenhouse gas emissions, the equivalent to taking over 3 million cars off the road.

2.   a. 1.7 million: If just one in 10 homes used ENERGY STAR qualified appliances, the change would be like planting 1.7 million acres of new trees.

3.   c. $550: Both “regular” and ENERGY STAR models are about equivalent in purchase price and cost less than the amount you can save by using ENERGY STAR – 3.2 cu. ft washers begin around $350.

4.   b. 12 million: According to the Wall Street Journal, around 12 million barrels of oil are needed to make 100 billion plastic bags.

5.   Each reusable bag you use has the potential to eliminate around 1,000 plastic bags over its lifetime.

6.   c. Nearly 4 months: Replacing a refrigerator bought in 1990 with a new ENERGY STAR qualified model would save enough energy to light the average household for nearly four months.

7.   c. $87 million: According to the US Dept of Energy, if everyone purchasing a room air conditioner in 2008 choose an ENERGY STAR qualified A/C it would save $87.5 million per year.

8.   a. Over 1 billion: 1.3 billion lbs of greenhouse gas emissions could be prevented if all people purchasing a room A/C in 2008 purchased an ENERGY STAR qualified A/C – the equivalent of taking 116,00 cars off the road.

9.   c. $188: Replacing a clogged air filter can improve your car's gas mileage by as much as 10 percent. This can increase an average car’s fuel efficiency from 24 mpg to 26.5 mpg saving you 47 gallons of gas per year - at $4/gallon that’s $188 per year. Your car's air filter keeps impurities from damaging the inside of your engine. Not only will replacing a dirty air filter save gas, it will protect your engine.

10.  Keeping your tires inflated to the proper pressure can improve your gas mileage by around 3%—-saving up to 18 gallons ($72 at $4/gallon) of gasoline per year.

11.  c. Aggressive driving can lower your gas mileage by 33 percent at highway speeds (in an average vehicle getting 24 mpg with proper driving would get 16 mpg driving aggressively.  In a vehicle with a 16 gallon gas tank this translates to filling up after 256 miles rather than 384 miles).

12.  Removing your shoes.  80% of dirt in homes is tracked in on shoes – taking your shoes off when entering your home prevents harmful pesticides from ending up on your floors and rugs and also reduces the amount of vacuuming that needs to be done (saving energy) and makes carpeting last longer.

13.  True. Recycling plastic uses half as much energy as burning it in an incinerator.

14.  c. $40: An extra 100 pounds in your vehicle could reduce your MPG by up to 2% or 10 gallons of gas per year – at $4/gallon that’s $40 just for lugging around unnecessary items.

15.  According to the EPA, homeowners can save about $180 a year by properly setting their programmable thermostats and maintaining those settings.

16.  b. $104: Driving with a roof rack on an average vehicle lowers gas mileage by 5% - an extra 26 gallons of gas per year – that’s $104 at $4 gallon.

17.  According to the Dept of Energy, businesses consume 80% percent of the total energy in the United States each year.

18.  c. $1500: According to the Dept of Energy, the typical U.S. family spends almost $1,500 a year on utility bills.

19.  c. ½ ton : Replacing one incandescent bulb with a compact fluorescent keeps ½ ton of CO2 out of the atmosphere over the life of the lamp.

20.  a. 90: If everyone in the United States used energy efficient lights 90 average sized power plants could be retired.

21.  c. 4: Having just 1 Incandescent light on uses the same amount of electricity as having 4 Compact Fluorescent Lights on.

22.  b. 90,000: The average U.S. family of four consumes nearly 90,000 gallons of water per year, costing as much as $500 annually from municipal suppliers.

23.  False: “Since recycling deals only with the back end of consumption (disposal), it treats the symptoms of the disease rather than its root cause: the overproduction of trash. The new approach to sustainable consumption, however, focuses not just on how we dispose of a product (recycling), but on how we produce that product in the first place (pre-cycling). It strives to create goods using nontoxic, recyclable, or reusable materials with the least amount of packaging and waste. In fact, pre-cycling is fast becoming the most effective approach to long-term sustainability.”

24.  c. 100 million: Each year the “junk mail” industry destroys about 100 million trees.
