I use about 30 kwh per day. In the summer, it could be 50% more with AC.

Thanks for all responses. Those of you who use under 300 KWh/month, do you have electric appliances at all? For us certainly the dryer is the biggest energy sucker I can think of.

3000 sqft home

around 500 in the winter
around 660 in the summer

With hydro prices being as high as they are I've replaced most bulbs in my house wth LEDs, installed a gas range etc. I am wondering how much power others are uising?
My situation: 2 adults and 2 kids, 2 story 3 bedroom house with a finished basement (2000 sqft including the basement), electric washer and dryer (they run frequently with two small kids at home), dishwasher. Some power tools like a table saw, jointer and planer, but I've not been using them this winter. Two small baseboard heaters in kids' bedrooms, but used very infrequently - the house is well insulated and the gas furnace does its job.


My monthly consumption:
Feb. 510 KWh
Jan. 659 KWh
Dec. 456 KWh
Nov. 502 KWh

I think January was higher because we turned on the baseboard heaters for a couple of hours most nights. By the way we keep our house at 70 degrees when we are not in, at 73 when we come home and 70-71 at night.

How does it compare to your situation? Thank you.

What do you use for heating/cooling?
In every month so far we're below average for consumption compared to our neighbours. We have some neighbours using over 3200kW in the summer.
We have mostly LED lights, but have computers and TV's on quite a lot of the time.
Electric range, 80% eff gas furnace with AC motor. We also have a gas fireplace with a 110v blower.
We have a 2600sq.ft, 5 level split, built in 1976. Attic insulation is about R10 blown fibreglass, windows are newer sliding units but a bit drafty.
I often have the HVAC fan blowing on a clean cycle (30 min/hr) to help even the temps between the levels, even if the AC or heat isn't on. It's an old PSC motor so not efficient. I've been thinking about swapping the motor to a more efficient one.

Here's my last few months. Jan-16 bill was way higher but I think it's because it included xmas (cooking, at home for 2 weeks with relatives over, etc).

I'm using tons. Must be my hot tub, but even with that I can't figure out why so much. 2016 data - in the cold months I'm blowing through over 1500 kwh monthly so 50 a day.

3 story semi brick 100+ year old home with all new windows (Andersen, brick to brick install), new flat roof w rigid foam insulation and a 10 year old mid-efficiency furnace. Fan blows a lot.

Gas heat, gas water heater, gas stove.

Electric dryer. 1 65" plasma which is on about 30 minutes on average a day. 3 MacBooks, 3 iPhones, 3 iPads, LED lights most places.

Time to put the killawat meter back on the tub and see if it's burning more than it should. Theoretically if it was running 24/7 it would be about 1300 kwh monthly (15A 120v circuit so 1800w x 24 x 30 = 1296kwh). I'm guessing it's running 30% of the time, so about 400 for the tub. The other 1000+ is a mystery.
You have to audit everything when you have usage you can't account for, killawatt everything in the house that plugs in no matter how big or small, from fridge to microwave to cable box to phone chargers. The problem is the items that are hard wired, your furnace, hot tub, dryer, oven (even gas uses energy, kill a watt it too) and so forth are hard to measure. You can get whole house energy meters but they don't breakdown by appliance, only buy whole house, Though you can shut everything off and measure instantaneous, such as furnace, and calculate its usage (BTU vs heating bill compare to blower motor) and dryer, determine load per load and count loads and so forth.
You will eventually figure out where your juice is going. It even possible your paying the wrong bill, for a neighbour or an account mix up at the power company. The whole house meter compared to the kWh on the bill will tell you this.

I can't fathom how some people have such high usage (unless on electric heat). We use 6-11 kw per day depending on the season and average 8.3 kwh/day for the year.

Family of 4 and someone is always home. All appliances are electric. Gas heat and water heater. We mostly prepare all meals so the appliances are in use.

I'd love to see what you end up finding out was the issue. With your consumption going up so much coinciding pretty linearly with the temperature, smart money is on space heaters, hot tub (do you really have a 15A 120v hot tub? If so, your 30% number is probably a REALLY low estimate, especially if you ever use it), dryer (they're REALLY hard on electricity), and just your furnace fan (which is probably a pittance compared to the rest). Spare fridges, especially cheap ones, are often power pigs.

Feb 2015 was over 2000 kWh.

I have NO idea why mine is so much higher than what others report. Clearly I can't be using 5-10 times what some of you are (family of 3, one TV that is rarely on, gas heat, gas hot water, electric dryer). I have a 100+ year old 3 story brick home with new windows (brick to brick install), new flat roof w insulation etc.

The only big variable is a 120v hot tub outside we run all year. But - even if it was running 24/7, that would be 1800w (theoretical max of a 15A circuit) x 24 hours x 30 days which would be 1,294 kWh. And obviously it's not running that much (I know this to be true, and have had a Kill A Watt meter on it before). I think it's likely about 1/3 to 1/2 that. Perhaps 400-600 kWh on its own, leaving me still using a boatload of power.

Not growing my own, lots of LED's and our lights don't stay on that much.

I dunno. I pay the bill and move on. I'll drain the tub and see what happens.
Aren't hot tubs usually 220v? So it should be 220v * 15A. That would almost make up your mystery 1kw

I run my furnace fan 24/7. I use electric clothes dryer, lots of loads. Six cable boxes, desktop computer running 24/7, lots of little loads that add up to a lot.

Yeah, little loads all add up. Cable boxes for example....The Rogers Nextbox 3 consumes 25W when on and 23W when off.
23W x 6boxes = 138W
(138W x 24hrs)/1000 = 3.31KWh per day OR 99kWh per month.

If the Furnace fan is a single speed pcm then could be pulling around 500W so 12kWh per day. A multi-speed unit will be better and an ECM motor will be a huge improvement. My ECM uses various fan speeds and consumes ~60w(fan only), ~175w(low heat), ~350W(high heat).

edit: corrected my calculation

The cable boxes are ridiculous. That definitely adds up. Six boxes seems crazy to me. Not a judgment at all. We barely ever use the one that we have so I can't really say anything. I think my main use of the box is that it serves as a clock.

The furnace fan on 24/7 is going to make a difference. I find that running it for 10 minutes per hour (when not heating) seems to accomplish the same.

We're a family of four (two kids aged 11 & 14) living in a 2800 sq ft detached home built in 1985. Furnace is 10 years old and HE with an ECM motor (from what I recall). I run the fan in circ mode which seems to help the house with warmer overall. Washer and dryer are 11 years old. New frig and gas stove installed a few years ago. Our usage is unbelievable. We're typically in the top 10% in our neighbourhood according to Powerstream's page and I honestly don't know what else I can do to reduce our usage. This month we were at 1317kwh and last month was 1467kwh. Warmer months are typically better but still doing 800-900kwh per month. The basement is unfinished and it is a bit cold so not sure if there's leakage there or just not insulated very well. I guess once we finish it we will see if it makes any difference.

You should buy a kill-a-watt; anything that plugs in, you can test. Might surprise you to find out your coffee maker is continuously drawing 100w, or your printer is consuming 40w just sitting there.
