Project Description:

Electricity is used to illuminate light bulbs in lights and light fixtures in your home. They are also used for street lights. Electricity is also used to heat electric stoves; so, those without electricity could obviously cook with gas stoves. Electricity allows you to use your computer, which is probably the most used reference and tool for writing papers, documents, and other necessities for school or jobs. Electricity is used for TV's, which a lot of people use for entertainment and news.

•Electricity bill•Wattmeter•Laptop computer•Laser printer•Desk top computer•Desk top computer screen•Internet (A-D-S-L) Modem•Router•14 inch C.R.T T.V•32 inch L.C.D T.V•Satellite receiver•V.C.R•D.V.D•Micro wave•Dish washer•Small Radio

TOTAL POWER CONSUMPTION OF ELECTRONIC APPLIANCES IN STANDBY AND

ON MODES

The wattmeter used to measure

Dell Laptop Computer

• On : 38w• Stand-by : 4w• Total Power consumption

on standby / Year : 35.04 KW

• Total Cost / Year :3.50 JD• Note : Laptop AC adaptor /

charger is the one consuming 4w on stand-by

Phraser Laser Printer

• On : 700w• Stand-by : 40w• Total KW Power

consumption on standby / Year : 350.40 KW

• Total Cost / Year :35.04 JD

Desk Top Computer

• On : 115w• Stand-by : 9w• Total Power consumption on standby / Year : 78.84 KW• Total Cost / Year : 7.88 JD• Note : Computer is not on standby it is shut down from

windows

Conclusion

Not only are we paying around 130 JD per year for devices that are on stand-by mode in one house, we are also contributing to air pollution because we use fuel to produce electricity.

How much money is the school paying on all turned off computers per year

Wasted money that we can give to the poor and needy or pay for more

library books

= ???

1.We measure the Computer’s Power Consumption in watts in Stand-by and ON modes

Stand-by mode ON mode

2.We calculate the Power Consumption in stand-by mode in kilowatts per year through this

equation

=26.28 KW / Year(4w /1000*18*365)

4.We calculate Total JD Cost per Year through this equation

=

3.We calculate Total Power Consumption in KW for about 300 Computers through this equation

26.28 KW*300=7,884 KW / Year

*0.0867,884 KW
