What a waste

1
What a waste!

• Ian Fehring

2
Some background info

• The U.S. consumes more energy than any other
  country in the world!
• We are lazy
• Drive when we could walk
• Do other unnecessary things to waste energy

3
Energy?

• Energy has a variety of ways to be measured
• Joules (J) - mechanical
• Work (W) - mechanical
• Watts (w) electrical
• Volts (V) electrical
• Calorie (C) heat
• British Thermal Unit (BTU) - heat

4
BTU?

• 1BTU the amount of energy need to raise 1lb of
  water 1F
• Standard unit used in ordinary commerce.

5
BTUs in Fuel

• 1 gallon of fuel oil 145,000 BTUs
• 1 ft3 of gas 1,031 BTUs
• 1 Kilowatt hour of electricity 3,412 BTUs
• 1 ton of coal 25,000,000 BTUs
• 1 cord (128 ft3) of wood 20,000,000 BTUs
• 1 gallon of gas 125,000 BTUs

6
More Background Info

• Americans on average throw away 4.4 lbs of trash
  a day.
• In urban environments, we average 7.3 lbs of
  trash a day per person.
• The United States throws out 250 million tons of
  trash a year.
• ? A lot of this is toxic as well!
• and all this trash has to go somewhere.

7
Where does all the trash go?
8
What is considered toxic?

• paints and stains
• pool and spa chemicals
• pesticides, herbicides, fertilizers and poisons
• motor oil, antifreeze and other automotive fluids
  
• thinners and solvents
• household cleaners and disinfectants
• batteries
• art and hobby chemicals
• aerosol spray products
• sharps (medical syringes)
• propane tanks or bottles from barbecue grills 
• ? A lot of stuff we throw away everyday!

How does this relate to a college student?

• For my project I examined 3 days of my life and
  recorded info regarding
• All the energy I used
• Transportation
• Electrical appliances
• Did calculations on heat loss, water loss and
  electrical waste.
• All the trash I threw away
• Measured it in lbs

10
Transportation for 3 days

• Foot
• Total 22 miles
• 4.5 was necessary
• 16.5 was for exercise
• Car 31 miles
• Bike 0
• Train 0
• Plane 0

11
31 miles in the Car

• Volvo 240 gets 21mpg city driving
• I used 1.48 gallons of gas
• 184,523.9 BTUs!
• While I paid 2.02 for a gallon I spent 2.99!

12
Electrical Appliances used over 3 Days
Does not include cooking I eat at Kosters or
go out for every meal! Does not include
lighting
13
138.506 KWh?

• Electricity is 0.08/KWh
• I spent 11.08
• And used 472,582.472 BTUs!
• ? I dont even cook!

14
Heating and Air Conditioning

• The size and of panes in a window can make a
  big difference in the
• Efficiency of retaining heat
• Amount of energy lost to the environment

15
My Window

• 2x3 SA 6ft2
• Single pane glass (R 0.9)
• Inside Temp 71F
• Outside Temp 52F
• ? I lose 126.67 BTUs/year to the environment
  because of 1 window!

16
of window panes is significant

• My window is single paned (R0.9) ? 126.67
  BTUs/yr lost.
• If double paned (R1.85) ? 61.62 BTUs/yr lost.
• If triple paned (R2.8) ? 40.71 BTUs/yr lost.

17
Water leak problem

• If water drips from the sink at one drip/sec
• In 15 min. 2.1lbs of water was collected
• Thats 73,584 gallons of water/year
• And 5,886,720 BTUs lost to heat the water
• And 405.98 gallons of oil fuel needed to heat the
  water lost!
• ? oil fuel is 1.30/gallon
• thats 527.77 a year for a drip!

18
Lighting

• 40-watt incandescent light bulb
• Light meter reading 4.72
• 40-watt fluorescent light
• Light meter reading 16.85
• ? Fluorescent lighting is 72 more efficient than
  incandescent lighting!

19
My 3 day Trash Inventory

• Collected items included
• Paper products
• Glass (primarily beer bottles)
• Metal (primarily beer cans)
• Plastics
• Total weight 24.5 lbs
• ? 8.16 lbs/day!

Nothing was recycled it all went to the dump.
20
24.5 lbs of Trash?

• Beer bottles were mainly responsible for the
  weight.
• Most of this trash could have been recycled!
• There are not adequate recycling bins on campus
  to dispose of this waste correctly.

21
Conclusions

• I wasted 726,092.86 BTUs in three days
• 5.809 gallons of gas
• It cost 20.25!
• I am a lazy, wasteful American!
• I dont recycle
• I am not efficient with electricity
• My heat is up too high
• Id rather drive instead of walk
• ? But its so much fun!

Just remember
