What is your average kWh/day usage?

Hot water was an instant gas unit. We are now renovating and have now partially installed a 30 tube evacuated tube collector and storage tank which we will combine with the gas booster. I'll be interested to see what that does to our gas consumption.

All our lighting is compact fluorescent. We use laptops instead of PCs. We have multiple switches for turning off standby power on grouped devices like stereos and computers. We don't have a big TV - we have a small old one but generally don't use it. Our house had three bedrooms and was not a big house. All these things helped keep our consumption down. Now with the renovated house it will be interesting to see how we go. The area is larger but the design is passive solar oriented so I'm hoping that our overall energy consumption will at least stay the same, if not drop a little further.

My average daily energy usage is ~4 kWh, averaged over the last year is 3.99kWh/day, actually. In the summer it's about 3.4, in the winter 4.6.

Hot water is on-demand nat gas, as is the boiler and stove. Electric oven, toaster oven, kettle. CFLs and halogen lightbulbs. Very efficient refrigerator (~700Wh/day). Electric lawn mower (~700Wh per mow), and 700W engine warmer in my car (used for 5-10h per month). I turn off phantom loads whereever and whenever possible. Unfortunately I have no chance to reduce electrical usage any further - this would require Dad-in-law's cooperation, and he's already ecoterrorized by us as it is. The big 170 watt LCD in the TV room was his idea, as was the driveway gate's motor, which sucks 32W 24/7 (I turn off its circuit breaker when both cars are at home).

We have plans, which keep getting put off, to replace the two on-demand gassers with an electric hot water tank (with optional future solar/heat pump).

For now, winter gas usage is equivalent to 80-150 kWh/day, while summer is only ~5 for cooking and hot water.

After looking through our natural gas usage I calculated that we use the equivalent of 4kWh for cooking and hot water during the summer, while the yearly average is 53kWh per day. Adding our electricity usage to that gives an average of 7.5 (summer) and 57 (year) kWh/day.
