Electrifying your household appliances - which in most cases means ditching a gas cooktop, gas heating and hot water - can save the average household more than $1000 per year, according to data modelling recently commissioned by the Energy Efficiency Conservation Authority [and Rewiring Aotearoa]. The study also found annual running cost and lifetime-cost gains from solar and swapping out a petrol or diesel vehicle for an EV - at least if you use cheaper charging at home rather than pricey public chargers, even allowing for impending road user chargers.
