Cost of leaving a 23W fluorescent bulb lit. Money waster?

[gatch]

I live with people a bit younger than me, who tend to make a huge deal of things because they have nothing better to do.

The latest debacle is one of the flatmates leaves her "energy saver" light bulb going when she leaves her room, the miserly flatmate thinks it is wasting money. He is not that bright. For the record, I couldn't give a flying fuck, it really doesn't bother me, at all. But I like squashing their dramas with simple logic. Yay for brains.

Anyway, I just did some rough maths on how much money is actually being wasted.

I figured the most we are being charged for our power is $0.38kW/H.
The offending bulb uses 0.023kW/H. The answer I get is we are being robbed of 0.874 CENTS PER HOUR. ZOMFGROFLMAOLOLRUS THE HORROR.

Does this seem about right ?

Your posting of this thread will have cost more than a week of that light bulb ...

YOU ENERGY WASTER ... :angry:

[Flip]

Sounds about right. $90 a year.

My flatmate switches off the PS3 (at the back) unplugs the microwave and dryer (which he says we are not allowed to use) then leaves the house for a few days (stays at his girls) leaving his computer running with no power saving modes on (so screen and hard drives still chugging away) and then when he gets home he jumps into his bed that is nicely warmed by his electric blanket.....:facepalm:

When hes gone i do a load of washing and then throw it in the dryer for a couple of hours :lol:

I'd get a new flatmate. Preferably one with big tits and no morals so you can root her. No need for an electric blanket then either.

Now that's some solid advice. :woohoo:

Won't matter even if she's ugly ... think of the power you'll save ... and you wont need to change YOUR sheets so often either ... (just use HER bed)

win win I say ... :sunny:

So I told the miser flatmate about his logic fail. He is not smart enough to comprehend what kilowatt hours are. So still doesn't really understand that leaving the light on is NOT going to bankrupt him.

I wash everything I can with hot water. I take long showers. I move his stuff around in the pantry to fuck with his routines. I've even taken to leaving half chewed bits of sausage around the house, then blame it on his dog. He's fun to annoy...

Never a truer word spoken. I'm working on mine now :innocent:

You could also point out that the energy saving bulbs are not at their brightest straight away, so it's not the type of bulb to constantly turn on and off.

I'd shudder a bit to think how much my PC consumes, with 7 drives, 2 graphics cards etc. Screens are off, but it's on 24/7

I doubt you're getting charged as much as $0.38 per kWh unless you're on a low user plan with hardly any lines charges. I pay $0.169 per kWh on a normal plan, at that rate leaving a 23W bulb on for an hour would cost 0.3887 cents per hour.

Who's your provider? I'm now playing $0.2529 per kWh with Genesis Energy. Was $0.2439 til the start of the month

I know it is actually less than 38 cents. But for the sake of simplicity I used the highest figure I could find on their pricing plan.

[sil3nt]

0.3887 cents is 1/3 of a cent.

Jeez I'm teaching maths here..

What a bunch of eeeediots.

I'm with Genesis as well. I guess Dunedin has lower electricity prices than Hamilton.

[ducatilover]

I'm on the "in charge" pre-pay for Genesis. As far as I am aware this is more expensive? Who knows the Palmerston North rate
(If it is different...)
That way I can quote useless facts and figures to anyone near or around my house.
Will reduce knob chaffing too.

[slofox]

Just on 21 cents per day! Wastrel!

Genisis has extremely cheap power in Dunedin, and the other companies can't compete. Genesis reported to the Electricity industry that they made an error in their pricing and didn't take into consideration Aurora's excessive line charges. Unfortuantely for Genesis they have locked themselves in for a period and can't raise their prices to where they should be.

They are able to compensate by charging the wholesale market $57M for a single day in late march when they had market power north of Hamilton.
