Two adults and two dogs, laptops only, 40" LCD TV, gas boiler and stove, all lights are CFL/LED which i try to have turned off most of the time. Daily KWH is about 7.5
Guess we are well below average but not low enough for my liking. I'll have to figure out the gas. |

Modi to Use Solar to Bring Power to Every Home by 2019 - Bloomberg I use ~200KWH a month, a little more in the winter. We don't need AC up here. Rob |

Hi all,
Interesting thread! I read power consumption (and generation) at the meter on the first day of each month (see attachment) and record that in a spread sheet. Household is older 2 adults, and 2 young adults. Power generation peaks in summer at about 10kWh per day, whereas our power consumption peaks in winter at around 20 kwh per day. During winter our solar power generation drops as low as 2-3 kWh per month. The offset is a problem for solar generation! That winter peak has increased due to our shifting to a reverse cycle A/C for heating (we still use evaporative A/C for most summer cooling). Because we purchase 100% green power (from wind generation), the electric A/C heating is more sustainable than the natural gas heating (which has high CO2 emissions). The priority I have is to reduce that winter demand - heating & lighting are the main culprits. Switching to more LEDs planned. We've renovated some rooms, boosting ceiling insulation and improving window coverings (air cell blinds)... but with an older house there are challenges, suspended wooden floors, gaps around doors etc. DG |

Wow! 7.5kW per day? That's good! I'll have to set my goal to further reduce my overall daily electricity consumption further (at this time of the year, 13kW/h per day typical is my family's consumption). Also: on an irrelevant note: I shall pursue the installation of a ERV in my house to further cut down winter heating gas bill (natural gas - radiant in-floor hydronic heating)... wish me luck. Q. |

Interesting thread!
My family of 5 (2 adults, 3 kids, ages 10, 7, and 4) appear to be averaging about 22KWh/day for the last year. Not the greatest, but I use propane (and a corn stove, but that also draws 200W 24/7 for at least 4-5 months of the year) for heat, and everything else is electric. I'm most proud to report that we are back down to where we were ~10 years ago before we had kids! Replaced electric water heater with a heat pump water heater, upgraded the furnace to one with a variable speed blower (I run that all winter to spread the corn stove heat around the house) and also line dry all the clothes when we can. Future plans are to supplement heat and hot water with some solar panels, though that probably won't do too much to the electric usage. mike Last edited by Daox; 05-23-14 at 07:40 AM.. |

Mike,
What are the units on the graph? Is this kWhrs per week? The average line appears to be at a level of "900" (~880 if I squint carefully). How do you get 22 kWhrs per day from this? No doubting you, but wondering. 22 kWHrs per day = 154/week, 660/month, 8030/year so I am having troubles understanding the graph units. Regardless, great job reducing your electric consumption! Steve

The units are kWh/month (graph goes back to 2000). I divided these numbers by 30 to get my 22 kWhs/day figure. mike |

Got it! The recent decrease in electric consumption is now especially evident.

Hi All,
Quote:
Total energy use: 15000kwh Our electrical use: 4044kwh Our natural gas use: 1186m^3 ( ~11000kwh) Water: ~26m^3 (~10,000 gallons) That is for a family of 4 in a 50m^2 (550sqf) house with 2 stories plus attic (That makes it some 1400sqf in total). NG use is for heating, cooking and tankless hot water. Over the past years our NG usage for heating has gone down due to better insulation. Last winter is not included in the above numbers but NG usage has dropped further due to the installation of the HRV plus the extremely warm winter we had over here. Our electricity usage is higher than average for our area but lower than average in the USA. But then again we don't consider AC as 'baseline usage' over here, only few houses even have one : ) Energy is a bit expensive over here, the energy bill for electricity + NG was €1806.19 (~$2.3k) (over the entire year, payed in equal monthly terms.) Electricity is 3 times the cost of NG per kwh. Last edited by Fornax; 05-23-14 at 03:47 PM.. |

in my area: electricity is currently @ 0.075CAD per kW/hr, up from the original 0.067CAD per kW/hr.
Due to some hydrodam new projects, the price for electricity will be up by 30% over the next 4 years...(already approved). While it may, by no means, expensive in NA standards, it is something that I want to make it more "manageable" in the long run. Natural Gas is market rate (currently @ 4.64CAD per GigaJoule, + delivery charge, midstream charge, etc.)...not bad given this rather harsh past winter (most parts of NA used up their NG reserves, drove the market pricing for NG up...) I recalled the lowest for NG pricing was 2 yrs ago where market value was @ 2.67CAD per GigaJoule. anyways, as I'm planing on the implementation of my HRV this summer, I'm looking forward to some more savings this coming winter, and many more to come.
