Cost of leaving a light bulb on
Hi guys,
Just wondered if anyone knew the average cost of leaving 1 standard lightbulb on for 10 hours? I accidentally left the living room light on today and my OH has had a right go at me for wasting money. I would like to know exactly how much money I've wasted if possible. Thanks in advance * dont worry as soon as I get home I'm changing it to an energy efficient one as well |

Our bathroom light seems to blow everytime you pull the string switch so we just leave in on 24/7, cheaper than a new light bulb everyday. I have not seen my bill go up that much. Ok perhaps £1 a year

Doing some rough calculations based on the price of electricity being £130 per megawatt hour (http://business.timesonline.co.uk/to...cle4888149.ece) and on the assumption that it's a 60 watt lightbulb, you've wasted approximately 8 pence.

You owe him £20 for beer for the worry and stress you've caused him after a hard day at work.

haha, my dad is always complaining about having unnecessary lights switched on... yes, he may not need much light to watch the TV but I need it to read! And all our bulbs are energy efficient ones.

If it was say 100W then it would burn one unit of electric in 10 hours. So what is your electric company charging you for 1 unit of electric? 11p maybe? |

To be fair to him, are you in the habit of leaving lights switched on? It may be be only pence (and the calculation you were given was for a low wattage bulb) but if you regularly leave lights on (and other things) the electricity soon adds up over a quarter and it is money wasted.

He sounds a bit of a control freak to me.
Using the UK average of around 12p per kWh (1000W per hour) then it would be (12/1000)x60x10 = 7.2p ! I'd give him 8p and tell him to keep the change.

Frankly he's just being a pillock, he must've had a shitty day and just decided to take it out on me. He also has a NAS box which is on 24/7 so he doesn't have a leg to stand on frankly. |

My ex husband was really anal about leaving lights on, we would've all walked round with wind up torches if he had his way
 One of the reasons why I divorced him

My Oh is the same as yours!! I get the blame for the high elec bills for leaving lights on but he never blames himself for leaving his computer on, chrging his phone every night, leaving TV on when he falls asleep etc

My other half is a mare for leaving the lights on. Frequently have to go switching them all off after him. I may mention it but don't give him too hard a time over it. Though he might disagree

It must be a crotchety old man thing. My husband is exactly the same. He even made me replace my computer mouse because it had a glowing light on it constantly. I mean, how pathetic is that? It's ok for him to leave the tv on standby overnight, however.
Ah, one day a Bear Grylls lookalike will come and take me away from all this mundanity..... |
