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!

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.

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

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

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

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

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.
