single person daily electric usage too high?

System

The OP should pop into his local library and see if they have an energy saving kit that he can take out on loan or, alternatively, he needs to buy something like this:

Then he just needs to move it around once a week to see which appliances are drawing the highest current. I have one of these attached to my home/Sky entertainment system. It goes off for 8 hours overnight and saves me about 0.75kWhs/24 hours.

I have a similar use and use 3kWh per day but with LED lights

Of course electric cookers use a lot of power. Appliances which use heat always use more juice than any other kind. Next group down are the ones which involve movement, especially fast movement such as washing machines when they spin, vacuum cleaners etc.

OP, your daily energy usage is about the same as ours averaged out over the year but we have solar panels. Without those, I reckon we would use nearer 10 kwh per day since we are here all the time.

Perhaps this link will be of use:

Stuff left on standby like cookers, washing machines, microwave ovens, TVs etc will all consume some power to keep the stanby-function active and that includes anything with a touch button rather than an actual mechanical switch so it can save a bit if you switch it all off at the wall.

Our microwave takes around 6 watts to keep the clock going, the induction hob & oven clock is around 10watts, the SKY box isn't particularly frugal at around 30-40 watts neither is the router at about 6-8 watts.

Dont forget that your gas boiler will also have electronics in which are live all the time and may have a pump and motorised valves which operate when heating water.

None of these things take a great deal on their own but it all adds up.

When we go away we can get our consumption down to around 3.6kwh a day and thats just leaving the A++ freezer on (fridge is switched off), the SKY router together with a couple of power-line adapaters and the SKY set-top box. We even shut the central heating off completely unless it's in the winter when it need to stay on for frost protection.

As Hengus suggests, you should get hold of an energy monitoring device if you are really concerned because if you don't measure it you don't know what's using it and therefore can't control it, unless you turn it all off. Just guessing doesn't help.

I think the phrase "measure, don't guess" applies.

Obtain a whole-house energy monitor and study the patterns for a few days. That should be enough to reveal any low-hanging-fruit energy savings that can be made. Your energy usage is already fairly low, so there may not be many easy savings to be made.

if it is just a small saving, it didnt worth the hassle and effort to change.
What I concern is, I practically didnt use any electricity during 5 weekday (Monday-Friday), only 2 min 750W microwave, and 2 min 2000W kettle to warm up water. I assume the electricity usage should be minimum 1-2kWh a day during weekday for fridge and freezer only (is this make sense?).
If this is the case, this mean my ceramic cooker use a lot electricity?? :eek::eek: a lot of electricity until it raise the daily average up to 6.2kWh a day?? This is huge electricity consumption - I might as well order take away then I cook myself then..?

ok, you are right, the only way to find out is by monitoring each of them one by one.

Why on earth are you standing for a dreadful electric cooker anyway when you have a gas supply. Even ceramics are super slow and expensive compared to the instant control of a gas hob. The ovens take an age to heat up.Gas kwhs are much cheaper than electric and life is too short to have to wait for an electric hob to do its thing.
Dump/sell the electric cooker and buy yourself a proper cooker. I ve never heard of a pro chef ever using the backward electric cookers

Wv've had gas, ceramic, halogen and now induction hobs and of them all induction is by far the best.

Clean quick, instant. Food does not burn on them so it's a quick wipe over when spills occur. They stop heating as quickly if not quicker than gas as all the heat is in the pan and they can be really fast, much quicker to heat up than gas.

There's no condensation from burning gas so the kitchen stays cleaner and all the heat is in the pan, not up the sides or into the atmosphere.

No way would we revert to gas even if we could, it may be a bit cheaper but I guess that's debatable when you look at the efficiency of transferring heat from the flame into the pan compared to the pan heating by induction..

Possibly because either a) the OP prefers cooking by electric to gas or b) it was supplied by the landlord.

I like our ceramic hob/electric cooker. Gas is smelly and scary and I won't have it! Why should I? I ain't no chef. :cool:

Smelly !! scary !..do you have a gas central heating boiler lol.the problems and costs with electric cookers are well documented. Any decent cook would nt stand for an electric hob never mind a chef.They don t even cook properly .
