My grandma recently moved into a nursing home and her house is being emptied ready to be rented. I scored her fridge (only owed by one elderly lady). It has a separate fridge compartment and freezer, which my old fridge didn’t. You had to open the fridge door to get to the freezer, so it wasn’t as efficient as a fridge with them separate. I had to defrost the old freezer more often than I would like. Also if you let the ice build up too much around the freezer compartment (which I had a tendency to do) you couldn’t close the fridge door, which meant it had to be defrosted right that moment.
It is no good just talking, writing or reading about sustainability. It requires us to do something toward that critical and vital end point – a sustainable world – so that we can all look our grandchildren in the eye with something like a clear conscience – Derek Wrigley 
For a number of years I’ve been interested in sustainable building design and I have a long term plan to build my own sustainable designed house. The first real-life example I visited was the Subiaco Sustainable Demonstration Home in suburban Perth. It was built by Subiaco Council, but is now privately owned. I’ve often wondered why more newly built houses aren’t designed using sustainable principles. I realise most such houses are individually designed by architects and this increases their cost, but some design aspects, such as passive solar principles, seem to me to be just common sense.
