What's your electricity usage?

[PeterC]

Similar setup, but electricity for all but CH: ~3.8kWh/day.

[Tim Streater]

I take it you mean 12.28kWh. Otherwise you'd be using 295 units per day.

[ARW]

It's what ever I decide the meter should read.

[Bob H]

Same here, it is what it is, and can't be bothered to keep looking at what is being used

[harryagain]

For everything. Minus 36Kwh/year.

[djc]

1 bed flat 5.3kWh per day (Nov?Feb), average over whole year 4.3

Gas cooking, central heating & Combi for Hot Water, so that is almost all lighting + computing.

[jgh]

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.

Four adults in a 2.5 bed semi with three tv and three PC working all the time, 12.8kw per day.

[Dave Liquorice]

Or an old PC like this one, approx 10 years old 1 GHz single core Athlon. Takes >150 W quite often on from 0800 to midnight. 2.4 kWHr or more than 10% of the average daily consumption...

[dennis]

Hmm..

I would estimate about 4000Kwh from a 4kwp solar array. So that's about 11kwh a day.

Its going to take about 20 kwh to charge the car.

So you don't use the car enough to need one.

[harryagain]

4000Kwh is about right. I don't use the car every day being retired. 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

[Tahiri]

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.

[Nightjar]

That is not an answer to the question asked. The amount you might generate is quite irrelevant to how much you use.

[Nightjar]

According to my annual statement, the electricity company expect me to use 25,425 kWh per annum. 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.

[Dave Liquorice]

How the f*ck 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.

[RJH]

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.

[Martin Brown]

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.

[PeterC]

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

[robert]

I have 3 storey 1800 terraced house, uninsulated rubble walls and slate floors , single glazed. Usually out 6 days a week. Heat average 3.5 rooms + bathroom + large hall , landings etc.

33kw in gas for heating , HW and gas hob. 11kw electricity. Your consumption looks high !

[R D S]

I've narrowed down the main culprits,

Son's electric heater is controlled by a digital thermostat and timer but it turns out that when he's in he likes to ramp it up and get all nice and toasty.

And we have a ceiling airer & dehumidifier (i'd entirely forgotten about this) in the spare room which is very effective at drying clothes, but apparently not cheap.

Managed to get away with 21 KWh on Sunday, which given that we we were all in, several loads of washing/dishwashing and a load of cooking was a result.

Onwards and downwards.
