Here is some "Real World" Data. I have an emporia energy monitor, which is 16 mini CT's for individual circuits in my panel box and bigger CT's for the mains.
For comparison to your homes energy use, my total consumption for the month was 1,323 kwh, that includes import from the grid, solar self-consumed during the day, and my battery discharge at night. I net exported 900+kWh.
For reading the chart:
CT1 and CT2 are CT's on my mains. They match with 99% accuracy my power bill and my sol-ark inverter data. (-) green means I net exported for the day, red means I net imported for the day.
(S) means that specific circuit is in my solar backup panel box. Ones without the (S) are in my main panel box.
My "Water Heater" is a heat pump water heater, and I only have it programmed to heat 2 hours in the morning, and 2 hours in the evening. It retains enough heat that water is plenty hot for several hours. This has saved over 10kwh nearly daily, and one of the best ways to reduce energy. Stop heating water when it isn't being used! Even a $50 timer on this appliance would make a world of difference
"Water Pump" is a 2.5hp deep well.
"Garage" includes a deep freezer and stand up fridge in my garage.
"Central AC" is a 3 ton unit I believe.
"Living room" also includes all my security systems, routers, network switch, and a lot of stuff that never turns off.
I recently put my phone/tablet chargers in my master bedroom on smart outlets that turn off at 9am and turn back on at 7pm. I can manually turn them on as well.
In Southern Georgia, we had 12 days of below 42 degree lows, and 11 days of above 80 degree highs. Some of these swings are within the same day, so central heat at night, AC during the day. Family of 3 most of the time, some weekends my 2 older sons and their girlfriends are home as well. I'd say average family use, not trying to live off grid or be super energy efficient, but we have been more conscious of energy use after installing our solar system. If I really wanted to minimize energy use, we could dramatically cut this, but this is a good base for I believe average households. I will say my home insulation is not the best, and I plan on re-doing that this year, which I hope to significantly reduce my central AC and Heat use.
Maybe this will help some visualize their own energy use.

Subject: How to make your Home Energy Efficient: Part 1
We have to ensure that our homes and offices are as energy efficient as possible in reducing waste of energy. With the rising increase of energy cost, it is important that we focus on energy efficiency to make sure that we benefit as much we can from energy we use.
Make small changes to everyday behaviour.
- Adopt habits such as switching off lights and appliances when not in use.
- Choose to air-dry clothes if possible, instead of using dryers.
- Avoid leaving the heating on all day but heat rooms for a couple of hours at a time.
- Keep doors closed to keep heat in and minimise drafts.
- Make a habit of looking out for the most energy efficient version when replacing appliances and electronics. For example, eco kettles can keep water hotter much longer than traditional kettles.
