I was considering ditching the old desktop PC and considering using just a laptop from now on. They consume way less power and I was curious as to how much electricity REALLY costs where I live in Newmarket, Ontario.
The hydro rates are expected to rise 33% in three years, as just announced, so expect that 500W power supplies for normal everyday users will become too costly. In fact, this Globe article suggests that the BASE price of power is going up almost 8 percent in the next five years. That suggests 45%.
Gone are the days of leaving the machine on 24/7 for the average household. Even hobbyists should take note.
Just worked some approximate math…
Because Newmarket participates in the Time of Use Electricity Prices, as mandated by the Ontario Energy Board, I had to average the price for 24 hours given the following formula:
100W lightbulb (or whatever) left on 24hrs a day, equals in a month (about):
$6.51 consumption (time of use changes throughout day considered)
$0.74 delivery charge
$0.10 regulatory charge
$0.10 debt retirement charge
$7.45 per month.
=$8.41 per month after taxes
*After Dalton McSquinty’s 10% feel-good give-back trickery provided you’re within the 3000kWh per month:
=$7.57 per month total.
That makes my 300W consumption (based on 450W power supply) desktop at 24×7 on worth about $22.71.
Left on all year, that’s about $272.52.
Laptop consumption is about 75W. Maybe it’s time to kill the old desktop….
BTW: This price did not include the static “$14.84” delivery charge (flat-fee for the month).
I suppose the next thing we need to look at is Monitor consumption!
