THE WAY OUT
Electrons Beat Molecules On Price
Rewiring Aotearoa's research puts the annual bill saving for a fully electric home at $7,600 compared with a gas and petrol household. Counting the upfront cost of the gear, that comes to about $3,000 a year, or $45,000 over fifteen years. Rooftop solar delivers power at around 12 cents a kilowatt hour against 26 cents from the grid.
Scaled up, that is $12.9 billion a year off national energy bills and $61 billion net by 2040, alongside around 58,000 jobs in the build-out. Roughly a third of large gas users could electrify profitably today with no support at all. Money spent on heat pumps and panels stays with the household instead of leaving for an overseas supplier.
