What's your electricity usage?
I live in a terraced house, 2 beds + an unofficial one in the loft.
Heating is gas except for a little fan heater in the small kitchen which keeps the place just above cold, and a convection heater in the loft room controlled by a timer to heat the room to a comfortable temp during the infrequent hours that my son is in there. Cooking is electric. Currently using 32Kw per day. How does that compare with other's usage? |

But when No.1 Daughter is home and the electric heater is on in her room it easily adds another 10 kWHrs. Power use plot shows it to be about 800 W on a 50% (ish) duty cycle 24/7. -- Cheers Dave. |

Cooking is electric. Currently using 32Kw per day. How does that compare with other's usage? 16th January: 16.88Kw - 5 bedroom semi, gas CH on all day, no thermostat pump runs all the time, 2 PC's (go on when we get up turned off at bedtime!), 2 freezers, 2 fridges, electric cooking. Both retired so around during day. Oh, ...and a 3Kw fan heater in the greenhouse on a frost stat. Using 0.55Kw per hour (OWL Monitor) as I write this. Suggest you investigate - I once had a freezer that the control knob had been broken so that it looked as though it was on a reasonable setting, when in fact much colder than it should have been. Power consumtion dropped by 20% when adjusted properly - it was the increased consumption that caused me to investigate. Peter |

Lounge heat pump uses about 4KW/day, cheaper than whole house gas. Workshop, garage heat pumps use 50KW over 90 days, not used much. Good insulation. |

Cooking is electric. Currently using 32Kw per day. How does that compare with other's usage? Seems a lot to me. Two of us in 4 bed detached. Primary heating is gas. My (business electronics) workshop on for probably 12 hours a day. Main desktop computer 24/7. 42" plasma TV (these are thirsty) about 6 hours. I record my usage every day and typical winter daytime is between 20 and 28 units / day, depending on whether I have to have any electric heating on in the workshop, and night time 6 units pretty steady throughout the year. Summer is a little less on the daytime on average, as no workshop heating. You could probably reduce the overall by a few percent, as washing and drying from our food business also gets done here, pretty much every day, sometimes on night time cheap, and sometimes not .... Yeah, I know ... but as we all know, fighting with the missus just ain't worth it ... :-) Arfa |

I've been looking over past usage and we'd typically use between 300 and 500 units per month depending on time of year. This has risen dramatically over the last few months and the only thing I can think of is that my teenage son has moved in with us (he's out 90% of the time), and we got a dishwasher in summer. I wouldn't have though that would cause our usage to almost double, i'm going to have to get my dad hat on. |

There's a PC in the front room, it's not massive spec, a dual core summat with GT8800 graphics that's left on more than it should be, do they pull much on standby?

Not sure but there maybe a setting to auto turn off after a given time. |

My missus tells me that she has to turn the lad's PS3 off every time she goes upstairs. Use a plug-in power meter to check the PS3, it's a bit juicy. When my son lived with me, there was 2 x TV left on standby (1W each) 1 x PS3 left on (24W running about 11W on standby) 1 x Old style Sky box (24W standby or running), New HD boxes are better(ish). But - the TV in the bedroom was often left on when he fell asleep (100W plus), lights left on (changed to low energy, 280W down to 40W). The net result was that the 'leccy consumption halved when he moved out. The number of times that I came home to both TVs on, Sky box on, PS3 on, lounge and bedroom lights on and number one son out for the evening...... Grrrr..... My bill in this house is approx 160KWH (£25 a month + standing charge). Mind you this is now a 2 bed semi, I was in a 4 bed det (thanks Virgin Money/Northern Rock) :-) Dave -- Blow my nose to email me --- This email is free from viruses and malware because avast!

I've got a Dell XPS laptop with a duff battery, it gets turned off but never gets unplugged, I guess that's always drawing power? Anything on standby will consume power, and that includes external PSUs, even when the load that they are connected to is, to all intents and purposes, off. If you have a lot of such standby consumption, then obviously, it does add up, but not to anything especially significant, even if you add it up over a year. A lot of nonsense is talked about standby power consumption. With modern equipment utilizing switchmode power supplies, the standby demand can be below a couple of watts, due to techniques like operating the supply in an eco burst mode. Designers of smps controller ICs, and the manufacturers of equipment that they are used in, have worked hard to get standby consumption down to the absolute minimum since eco-bollox green mist took over our daily lives. A lot of ill-informed advice has been given out in recent years about switching equipment off completely when it's not in use, but as a very long-term repairer of switchers, I would never advocate this, as the time that they always fail, is at switch on, after having been off for a while. Left alone, they are generally very reliable these days. Bear in mind also when considering what you might turn off to get consumption down, that many manufacturers have their equipment put into standby rather than full off when you hit the button, in order to facilitate various housekeeping functions, such as automatic software updates, and EPG an OS updating on STBs. As to why the household consumption has gone up since a son moved back in, I would be surprised, from experience, if the two weren't directly related ... It should be easy enough to take some covert readings first thing in the morning, last thing at night, and in between when possible i.e. at the weekend. This should give you a good idea of when the high usage is, without alerting the boy to what is going on. As to the PS3 or whatever being on, these can pull a lot of input power when they are running some of the games, even idling. Call of Duty is particularly bad for thrashing the graphics engine very hard ... Arfa |

According to my annual statement, 13130kWh gas and 4455kWh electricity.
I think that's on the high side as the statement included a £240 refund. 1892 terraced house, split into two 2-bed flats. One gas cooker, one electric cooker, gas central heating and hot water. jgh |

I could manage without but shrouds don't have pockets. A full charge would be 16Kwh, taking 8hrs at home. I never run it to depletion. (Now that would be a stupid thing to do) Usually around 30% to 60% depleted. ie = 6Kwh-10Kwh is needed to charge. I once ran it down to 90% depleted. I try to recharge the car from the PVpanels, ie when the sun is shining. Probably get 75% of power for the car for free. Just keep an eye on the weather forecast. My main consumer of electricity is the TV which is plasma and on at night. (No PV power). And freezers. I have a time switch on them to prevent them coming on at night in the Summer so making use of the PV power by day. You can buy battery systems but not worth the expense. I know someone who has them though. In Summer he use virtually zero mains electricty. They only need enopugh capacity for one nights use. (TV lights etc) He has an enormous (rotating) PV panel. So even on dull days he can charge his batteries. You could make up a setup from easily available parts foromeg Machine Mart. Prob. a £grand I think batteries (life) would be the problem |

Will depend a lot on the occupancy - is the house occupied during the
day ? No, we're both out at 9.00am ish and back in at 7.00pm 5 days per week. Son is at college, out at 7.00am & don't see him again until 11.00pm. In most of the weekend. How far away is your son's college? Having had sons of that age at home I would suggest you try a few unexpected visits home during the day, if you can, to see if he is really out all day or not. |

Detached three bedroom house. I don't have gas and the only insulation is 100mm of mineral wool in the loft. The roof will need replacing soon, so that will come out and I will have Celotex between and under rafter insulation fitted to bring it up to current insulation standards. Several windows are showing various degrees of rot, so they are also on schedule for replacement with modern double glazed units. I will probably have the cavity walls insulated while I am at it, so the estimated use will probably be wrong. Colin Bignell |

Similar setup, but electricity for all but CH: ~3.8kWh/day. How the feck do you get it so low? Our "everyone asleep in bed" base load is 300 W or 7.2 kWHr/day. Daytime base load is around 1 kW, but then we self employed and normally in rather than M-F 9-5 wage slaves. -- Cheers Dave. |

I live in a terraced house, 2 beds + an unofficial one in the loft. Heating is gas except for a little fan heater in the small kitchen which keeps the place just above cold, and a convection heater in the loft room controlled by a timer to heat the room to a comfortable temp during the infrequent hours that my son is in there. Cooking is electric. Currently using 32Kw per day. How does that compare with other's usage? 1 or 2 adults, in about half the time, 4 bed terrace, Gas CH, water and hob, everything else electric including shower - about 4kW/day through the year. But then I am quite mean and have bought low energy things the past few years. The oddest thing for me, though, is gas. My winter consumption has increased from 30 kW/day to 50 kW/day when comparing my previous house, which was much the same size/insulation and had a non-condensing boiler. -- Cheers, Rob |

Mine is a bungalow and 10kWh/day average annual usage including a 3kW thermostatic fan heater in my office during cold winter days. Oil CH. Daytime base load about 500W tops and night time 100W. My fastest PC (but with no gaming graphics card) runs cold idling at 65W and 200W flat out. Most frequently used lights are now all CFL or LED. I used an OWL and a individual power monitor to find and eliminate unnecessary base loads using smart sockets. Suspect TVs on high power standby and badly behaved PC sound systems as likely power hogs. There is usually a setting buried deep in the menus to disable the TDTV decoder when the set is nominally in "standby". I could shave another 12W off base load if I powered down the router overnight. -- Regards, Martin Brown |

Um, not sure - I've just checked it again, taking the two highest ½-year amounts and that's it. At night there'll be the fridge-freezer occasionally and the boiler circuitry, plus 1W for the PVR. Peak load would be the shower (4.75kW) for a few minutes, the kettle (3kW) and the washing machine (2.2kW intermittent) which is 8kg so used about 1.5 times a week. -- Peter.
