Your Mains and HVAC definitely. We use the Dryer a lot in winter and hardly at all in the summer. We have solar thermal hot water that supplies virtually all of our hot water for six months and hardly any the other half when it uses electric backup. We grow micro-greens under lights in the winter so there is a seasonal load in the basement. Our bills are high in the winter and low in the summer, but if I subtract those things: Heat-pump, hot-water, Dryer and basement, I get a pretty steady base-load of 13.6 kWh/day average for the year.
and the 2020:
All 13.6kWh/day. So our habits have not changed in a big way. Variations in consumption are mostly seasonal with the big variable loads:
See how the base-load is steady year after year. With this data, I can see that heating is a big user and is measured. If I wanted to try to reduce usage more, I would probably try to chip away at the base-load. It’s a little less than half of the total, but most of it is steady throughout the year so knocking off 1 kWh/day would save 365 kWh per year or 7.3% of the base-load.
That’s how I approach managing my usage. I keep an eye on the base-load and manage the seasonal loads individually. With years of data and Graph+, it’s easy to take the long view.
