1. Suppose you bring 100 pounds of groceries into your home each week. Please estimate how many pounds of each type of waste leaves your home. Does this add up to 100 pounds? Where do the various forms end up?

2. If you use 1000 kilowatt-hours of electricity in a month, what is the equivalent energy measured in gallons of gasoline? You can use the following website calculator to help you convert units. How far could you drive a car in month with the same energy?

3. If you install a low flow (1.1 gallon/min) showerhead instead of a regular (2.6 gallon/min) showerhead, how much water would you save for a 10-minute shower?

Solution

3. Saving of water per minute in low flow showerhead against regular shower head = 2.6 - 1.1 =1.5 gallons

Water that can be saved in 10 minutes =1.5x10 =15 gallons
