I live in a 1-bedroom apartment & my electricity is under the 1-person household level. I giggle internally when I see the link for Energy Reducing hints on my bill.

My windows are locked open 6" or so, & I use small fans in occupied rooms in summer, & warmer clothes in winter as my part of Sydney is not cold, tho folks further west need heaters, no doubt some/many of my neighbours have heaters. I'm about half a km from the harbour (hidden behind buildings) & have friends on the harbour in a very cold 2 bedroom terrace a couple of kms away who are already using their winter quilt & heater. Folks further west (30-40km) have night-time averages below 10C mid winter. Folks in parts of the Blue Mountains (100km) can get snow.

But I'm ok in my little bit of paradise as winter draws on ...

Today I took 2 bags of useful stuff to my favourite charity shop, a craft shop & came back with 3 small balls of wool! Not that I don't have more than a lifetime supply of yarn ...
