Poll: How Often Do You Turn Off the Power to Your Internet Connection?
Authored by: alanf on Aug 06, '08 06:37:32PM
I was curious about household power usage so I bought a UPM electronic energy meter at Canadian Tire. Here is some interesting things I found out.
My neighbours power bar uses 13 watts all by itself.
Annualized this costs $5.69 (Canadian @ .05 KWH) (365 x .013 x 24 x .05)
One of mine uses 7 watts.
Annualized this costs $3.06
Not sure why but possibly it could have something to do with the surge circuitry ???? because all of my other power bars have lights on them and use no measurable watts.
My iMac 24 uses from 61 to 83 W. It jumps all over the place and I have no idea why. Certainly nothing obvious is happening. I started 8 different programs and the watts used went up about 5 watts. While programs are started up it goes up briefly about 15 20 watts. On startup it spikes up to about 90 watts. My programs are the run of the mill ones and the Microsoft suite.
Interestingly when a program crashed the consumption did not change.
The Belkin wireless router uses 1 to 2 watts and my Wimax modem uses about the same.
When the computer is asleep it uses about 1 to 3 watts so @2 watts this would annualize at $ 0.87 . Throw in the router and modem and it doubles to $1.74 so cost is not really an issue.
Probably in the winter the added heat is useful in the house but not in the summer.
One thing is that wireless routers concern some people due to RF floating around to the point that I heard that in France they are not legal in public places. Not sure if that's true.....
My conclusion to this entirely unscientific but interesting examination is that I am going to leave it on except maybe doing electrical storms and when I go away on trips. The reason is that I wish to take care of it because it uses more electricity to make a new one or replace parts in the current [oops : ) ] computer. I drive my car only when absolutely necessary choosing instead to hoof it or cycle.
However my girlfriend says that the Apple dealer told here to turn off her MacBook daily. A laptop is a different deal due to the battery. I suspect that the heat may affect the laptop's life or the battery life...... , due to the cramped quarters in it's case. Not sure, does anyone know?
