Desalination in Australia

The Sustainability of SWRO
Energy Comparison – The MacMansion
If you look at all the energy requirements of new homes (City Beach 8858
kW/hr per year average per home) you would not believe there is a
greenhouse gas emission issue.
Some Big Mac’s (supersized) have up to 15 kW air conditioning systems.
To add insult to injury, the latest fashion is a black roof with no eaves –
additional air conditioning required (high calories – just like the Big Mac
supersized).
Reverse Cycle Air 15 kW @ 4 hr/day in Winter and Summer (6 months) =
10800 kW/h (SWRO water for 8.5 homes
I did not see one black roof on the Canary Islands (and I do not think it
was just because the islanders have aesthetic appreciation).
