Together, Australia’s houses could produce more electricity than they use, according to think tank Beyond Zero Emissions. And the transition need not take long.
The analysis, released recently in its Zero Carbon Australia Buildings Plan, shows that comprehensively retrofitting our buildings with insulation, double-glazing and efficient lighting and appliances could more than halve their energy use.
On our rooftops, we have space to accommodate enough solar panels so that our homes would collectively produce more energy than they consume, averaged over a year.
The report’s lead author, Trent Hawkins, says energy efficiency has a crucial role in reducing our greenhouse gas emissions.
