Title: Energy, Energy, and More Energy

Energy, Energy, and More Energy!

Its Everywhere

but where does it come from?
  • Although you can't tell when you plug your
    appliances into the wall outlet, there are many
    different sources of energy. About 99 of the
    electricity in the United States comes from
    fossil or nuclear fuels produced in power plants.

Did You Know Most power plants operate on only
35 efficiency!
4
Distribution of Energy in the United States
97 of Allegheny students have a refrigerator on
average, students leave their T.V. on 2.5 hours
and their main light on for 5.9 hours.
5
Energy Vampires!theyre lurking all around us
  • A TV with a remote uses more energy in the 20
    hours it is off than the 4 hours you watch it.
  • Some appliances use energy even when they are
    turned off

in fact, these energy vampires add
20 to monthly energy bills and cost the US 3
Billion annually! Some of these include
TV, VCR/DVD, Computer/Printer, Stereo,
Microwaves, Coffee Machine, Washer, and Dryers
6
Take a Closer Look at YOUR Energy Consumption
  • Average time an Allegheny student leaves their
    computer on 18.4 hours
  • Average time spent using computer 5.2 hours
  • If all these computers were turned off when they
    werent being used, 1980 watts per computer per
    day would be saved
  • This is equivalent to
  • 87,446 a year!

Alleghenys (and Your!) Total Energy Costs
  • For FY2005 (Fiscal Year, Sept 2005- June2005)
  • Electricity
  • College Cost 814,689.96
  • College Usage 13,063,282 kwh
  • Individual Cost 407.34
  • Individual Usage 6531.64 kwh
  • 1.22 of tuition and 12.7 of room and board

8
47 of Allegheny students say their room is
overheated
Heating (natural gas) College Cost
1,010,436.00 College Usage 98,530 mcf
(mcf is a unit of volume equal to one thousand
cubic feet) Individual Cost 505.22 Individual
Usage 49.265 mcf
1.51 of your overall tuition and 15.7 of your
room and board goes towards the purchase of
natural gas for heating

  • Total Energy
  • College Cost
  • 1,825,125.96
  • Individual Cost
  • 912.56
  • 28.4 of room and board

10
FY 2006 Projections
With the information for July through October and
trends in past years, we were able to estimate
projections for the cost of FY2006.
  • Electricity
  • Transportation/kwh .0178
  • Cost/kwh .0427
  • Total Cost/kwh .0605
  • So far this year, we have used an average of
    244,236.6 kwh more per month from FY05. Assuming
    this trend will continue we will use 2,930,839.2
    more kwh this year.
  • Estimated Cost for FY06 967,644.33 or
  • 483.82/person
  • Total individual cost for energy will
    essentially increase from 912.56 in FY05 to
    1118.85 in FY06. A difference of 206.29.where
    will this money come from? A raise in tuition?

11
  • Heating
  • Transportation/mcf 1.34
  • Cost/mcf11.54
  • Total cost per mcf 12.88
  • Projected Cost for FY06 1,269,066.40 or
    634.53/person
  • assuming we use roughly the same amount. Its
    important to realize considering this estimate is
    probably low due to continuously changing prices

12
What should we do?
  • Turn off all appliances when you leave the room.
    If youre going on vacation or will be gone for
    extended periods of time, unplug appliances.
  • Hang dry clothes when weather permits and dont
    put just one item in the dryer.
  • Wash clothes in cold or warm water instead of hot
  • Turn down your heat instead of opening the window
    and dress appropriately for the weather
  • Use ceiling fans instead of air-conditioning
  • Seal windows with plastic in the winter to
    prevent drafts
  • Un-prop open doors on campus
  • Take shorter showers

13
Energy Saving Devices
  • Many appliances now come Energy Star approved
  • On October 5, 2005 , the EPA and U.S. Dept. of
    Energy launched its Change a Light, Change the
    World Campaign
  • If every US home changed just one light to
  • an Energy Star qualified one, we would
    save
  • enough energy to light 7 million homes and
  • prevent greenhouse gas emissions equivalent
  • to those of 1 million cars.

An Energy Star Light bulb uses 2/3 less energy
than a conventional bulb and lasts 10 times as
long

Some of the things we came up with
  • Take a week off in February and add a week in May
  • cutting out a week of heating costs
  • Set all campus dorms to 65 in winter
  • Install motion sensors for lighting in all
    bathrooms
  • and lounges
  • Install low-flow shower heads to conserve hot
    water
  • Install curtain rods over all windows to trap in
    warm air during
  • winter months, especially at night
  • Rather than allowing individual refrigerators,
    provide hall refrigerators. Less energy is
    consumed and the greater
  • quantities of food mean you can turn down
    the
  • temperature.
