A Note To Instructors: Because of volatile energy prices in today's world, the instructor is encouraged to vary energy
prices in affected problems (e.g. the price of a gallon of gasoline) plus and minus 50 percent and ask students to
determine whether this range of prices changes the recommendation in the problem. This should make for stimulating in-
class discussion of the results.
1-1 (a) 62 million tons per year × (0.05) = 3.1 million tons per year of reduced greenhouse gas
$1.2 billion ÷ 3.1 million tons per year = $387.10 per ton
(b) 3 billion tons per year × (0.03) = 90 million tons per year of reduced greenhouse gas
$1.2 billion $X billion
=
3.1 million tons 90 million tons
X = $34.84 billion
, 1-2 The primary disadvantage is the installed cost of $8,000 (rather expensive!). A key advantage of synthetic
turf is the annual savings due to lawn maintenance. This may be worth up to $1,000 per year when periodic
lawn mowing, watering, and feeding are avoided.
