It might suprise you to take note, the average power supply for any habitable building doesnt change much. Let me illustrate:
Most houses run an 80 amp supply and have the followjng basics in their electric panels…
- Power circut = 16-20 amps
- Light circut = 10-16 amps
- Cooktop/oven = 20-30 amps
- Hot water - 20-30 amps
- Heat/cooling = 20-30 amps
As.you can see, if everything above were runnjng at 100%, the supply couldnt handle to load, however, we dont calculate residential eneegy needs based on 100% usage. Mlst applianes dont use anywhere near the amperage assigned to their circut. The bad ones in the above list however are cooktops/ovens and trsditional element type appliances suvh as element type tank storage hot water systems. These two are notoriously bad for high energy consumption
It does not actually matter much whether your house is small or large, the above are the bare minimums, however take note of the ones used daily that draw large amperage…oven/cooktop and hot water. These two are energy sinkholes
True a poorly insulated building is highly problematic in that certainly heating/cooling can draw large amounts of energy, however, quite often poorly insulated also means poorly sealed!
Having said that, id suggest that even in a comfortable temperate climate where heating cooling are not even being used, the electricity bills of your house and his tiny uninsulated home would be suprisingly similar per person when it comes down to the basic supply needs and usage.
That brings me to hot water…quite often when owners wont spend money on insulation, they also wont spend money on energy efficient devices…particlarly when in comes to hot water systems. An continuous flow/instantaneous gas hot water system for example is miles more efficient and far less wasteful of energy than a traditional tank type electric hot water system…this is even more of a problem when its a large capacity system and not all its hot water consumed. That means its heating significant quantities of water for nothing…all systems eventually radiate heat and the water cools…thats an unavoidable reality.
Another example…heat pump hot water in many climates is a far better option than traditional heating element type systems…in other climates heat pumps systems are useless…
So the equation is more comlpex than just insulation, its quite often a mindeset that adverley affects other areas of energy usage in the home and its suprising how quickly a little bit of inefficiench adds up to a lot of waste …a bit like my $6 cup of coffee per day could pay off 30k towards a home loan analogy (hmmm maybe i havent told this forum about that yet???)
Sorry…ive gone offtopic. I have a bit of a passion for home renovaions, energy usage, the electric car saves the environment bullshit, and how not buying a coffee and curbing unecessary spending, debt consolidtation etc, can help an indivudal pay off a home loan.in a modern world where affordability in house seems an impossibility for young people in the workforce these days. One of my aunties was a chain smoker…a habit so bad she could finance a new mid sized family car every 4 years with her cigarrette habit!
Also, electricity isnt the only comparison one should be making there, add water usage and cost into the mix and see what the comparison also is.
