As I dither about installing a solar photovoltaic system on my home I also spend a lot of time thinking about electricity consumption in general.
When I first contacted a few solar installers in my area—who have all been very responsive which is a sharp difference from other home service providers lately—all of the systems were sized far in excess of my needs. I have written before about my household electricity consumption and it remains something that baffles me well into 2017.
The twelve month rolling average electricity consumption of my household is approximately 400 kWh. It has been stable within 20 kWh of this number for about three years. What does that number mean in comparison to the average U.S. and Iowa household?
According to the Energy Information Administration the average U.S. and Iowa households consume approximately 900 kWh and 847 kWh per month respectively. What the hell are people doing with all of this electricity?
It is not as if I live in a small house without the use of many electric appliances. We have a large-ish French door refrigerator, chest freezer in the basement, electric dryer, and an electric range. When I lived in a house with a gas range, gas dryer, and no deep freeze the monthly average was below 200 kWh over the course of three years.
We use the air conditioning in the summer, although it is rarely icy like in some houses. We cook at home all the time using the electric range and small appliances like my beloved Instant Pot. There are two elementary school aged children in the house so we run through a lot of clothes that often times use the electric dryer. Sure we turn off lights in rooms, have LEDs in all but a few fixtures, do not watch very much television, and generally exist in a somewhat analog entertainment world (e.g. books that are actually printed on paper occupy many an end table spot).
It makes me question the urgency to install a solar photovoltaic system. Yes, such a system would divorce me from the somewhat dirty grid in Iowa where even though a large percentage of our electricity is wind derived much of the rest comes from coal. However, would I be better off investing that capital in something else that might have more of an impact ecologically speaking?
Furthermore, if I am living a modern life at half of the juice—so to speak—of the average household in my state doesn’t that mean we have a lot of room to become more efficient without really sacrificing anything in terms of modernity? Just some random—kind of like the Tweeter in Chief going off in the morning—thoughts for a Monday afternoon.
