As a retired chemical engineer Peter Johnston takes a practical approach to his passion for climate and reducing carbon emissions.
‘I figure I’ll start with what I can control myself, which is my own house,’ he says.
He began by easing off on the gas-ducted heating in his Glen Iris home. The family started using existing split systems to heat and cool rooms they used most and then added one more split system for the formal lounge and dining room.
Draught proofing and double glazing came next to regulate temperature in the house, then a heat-pump hot-water system powered by existing solar panels. Installing an induction cooktop was the last step to a gas-free home.
‘The thing about gas and all fossil fuels is they use a lot of energy, they create a lot of pollution and they’re quite inefficient,’ says Peter.
The results? His home now uses 84% less energy and generates 63% fewer emissions. And he puts his new-found knowledge to use by encouraging his friends and family to electrify their home. He also does energy audits on local homes and scout halls for community group Electrify Boroondara.
Peter has just bought a small electric vehicle and next on his list is a bigger solar system with a battery.
‘My advice is to take things one step at a time. It can be overwhelming for people to think about the whole thing, one step at a time makes it doable.’
