Are you suggesting these are bad things? I think they're positive however, it varies wildly across different locations and demographics.
> I would like to see how much energy the average Australian household consumes.
Again, an average figure wouldn't be that insightful, as there are probably massive differences in different populations. Additionally, building standards change things considerably (presence or lack of insulation, double glazing, ceiling height, aspect) - certain eras and locations (often due to regulations) get these things right, others don't.
I'm not sure how much consumption would go up if power got cheaper, but mine sure would... I really dislike being cold inside my own house. That said, I much prefer living in Australia to the U.S., especially while raising a family.
As a local; yes it is a bad thing. I want cheap energy. Cheap access to energy is literally one of two things separating us from animals. The other thing is higher intelligence.
There is room for an ideological debate on the meaning of good, but this is an outcome of regulation that the government didn't push for and that the votes would not choose if they had to tick a box.
I didn't think I suggested these were bad things. Perhaps I was just over-generalising. I was just pointing out (badly) that my observations from living in Newcastle are different than my observations living in Southern California. I agree that they are positive.
A/C was limited to a single in-wall unit that was only to be used when outside shade temperature reached 95 F / 35 C. If you wanted to cool down, it was a fan or go for a swim.
Heat was whole-house, natural gas with floor registers, set to inside 65 F / 18 C max.
House had both fiberglass and blown insulation, automatic ridge-line roof venting, tall tree shade, multi-pane windows, weatherstripping, room isolation manual practices (door and register closing), etc. This was in the 1980's-1990's before "green" was standard practice, it was self-interested to save TCO money.
