1. Killing 'Vampires': Saving Money
and Power by Turning Off Computer
Peripherals
S1240049 jun saitou

2. Introduction
 Industry has developed greatly in the past few centuries since we foun
d energy.

 Production capacity improved explosively since we came to be
 able to move a mashine using energy. As a result, We became able to
produce various things.

 A large percentage of the energy that most people currently use come
s from burning fossil fuels.

3. Introduction2
Most of the energy contained in fossil fuels comes from the combustion of t
heir hydrogen.
NOx and SOx are also created by burning fossil fuels and are contributors to
acid rain which can harm plants and aquatic animals.
If we cut down on burning fossil fuels, we cut down on releasing chemicals t
hat are dangerous for our health

4. Introduction3
While helping the environment is a great reason to save energy, another gr
eat reason to save energy is to save money.
many people turn on their computers at the beginning of the day and leave
them on all day, even if they are not using them.the computer is consuming
energy. Additionaly,Other equipment, like printer faxes, have clocks that n
ever turn off, even when the equipment is off That is wasted energy.
These appliances are called vampire loads

5. What is vampire loads
The villain in question is vampire power, also known as standby power and
phantom load.
We can also find it referred to as vampire energy, leaking energy, wall wart
s, standby loss, idle current, phantom power, ghost load and vampire load.
The terms refers to the electricity many gadgets and appliances waste just
by being plugged in.

6. Abstruct of topic
Equipment like televisions, computers, all use electricity to operate.this eq
uipment might still be sucking electricity from the wall, even when we think
it's turned off.For example, when we fall asleep. We always waste power.

7. Object of topic
To resarch and ultimately reduce the amount of power that computer perip
herals use.
To know vampire loads in your house

8. Summary of topic
This experiment take us about2-4weeks to get good results.
The cost of this experiment is about $20-$50.
It required adult supervision. This is because,We should be careful whe
n dealing with electricityand electrical equipment.

9. Materials
 Materials required when examining
 An electricity usage monitor or meter
 Coumputer and at least three peripherals
 Adult helper
 Power strip
 Lab notebnook
 Graph paper

10. Experimental Procedure
We will examine the vampire loads of our computer peripherals. Accorodin
g to the following procedure.
1.Plugged into electricity usage monitor and wall and turned on.
2 Plugged into electricity usage monitor and wall and turned off.
3.Plugged into electricity usage monitor and wall and standby mode.
4.Plugged into the power strip,electricity usage monitorand wall and turne
d on.

11. Experimental Procedure 2
If our equipment may not have the standby mode,just remove that test con
dition.
We will be testing each computer peripheral for 8 hours,three times each.

12. Equipment Testing
We measure consumption electricity. Accoroding to the following Testing
1.Plugged into electricity usage monitor and wall and turned on.
2 Plugged into electricity usage monitor and wall and turned off.
3.Plugged into electricity usage monitor and wall and standby mode.
4.Plugged into the power strip,electricity usage monito rand wall and turne
d on.

13. Analyzing our Data
Review the data that you collected with a bar graph
As a result,We will notice how much power do you waste.
Our household may lose vampire loads.

14. Kill vampire
Unplug or shut off main power switch for devices that are infrequently use
d.
Unplug your device chargers from the wall (cell phones, calculators, iPods, t
ools) when you are not
charging the device .
Turn you computer monitor off when away from your desk.
