A new study says that all Australia’s existing housing could be retrofitted to be zero emissions within ten years. Households could halve their energy use and go gas free. Australian households currently spend approximately A$15 billion every year on electricity and gas bills: this could be largely eliminated. Making this change would not only meet our emissions reduction targets but place Australia as a leader in a future carbon-constrained world.
The plan, launched today by Beyond Zero Emissions (BZE) as part of the Zero Carbon Australia project, is a follow up to the Stationary Energy Plan, which showed how Australia’s electricity could be supplied by 100% renewable energy sources within 10 years.
Most Australian homes are based on designs from a time when energy was cheap and plentiful, and we weren’t aware of the impact CO2 was having on our climate. Consequently, Australian homes are poorly built for our conditions, wasteful and often uncomfortable. But we can fix them with technology we’ve already got.
