A pathway to savings for households, economic growth for the community, reduced emissions and greater resilience.
{{location}} has crossed the electrification tipping point where homes can save money and reduce their emissions by going electric. The technology is proven, the economics stack up, and the transition is already underway. But there are still plenty of households paying more than they need to by running on fossil fuels.
For an average {{location}} home (using gas for cooking and heating, driving two petrol vehicles), energy spending is spread across multiple fuels, each with its own bill, its own price fluctuations, and its own supplier.
When a {{location}} home electrifies (using electric heating and cooking, driving two EVs, plus solar and batteries), they consolidate their energy into a single source — electricity — meaning lower bills and far greater control.
Solar offers strong payback for {{location}} homes, even in shaded areas, while improving energy independence. By pairing an {{solar_cost}} {{solar_size}} rooftop solar installation with a {{battery_cost}} {{battery_size}} home battery system, a {{location}} home will save {{solar_battery_15yr_savings}} on bills over 15 years.
With a mix of solar, battery, and grid electricity — financed at {{solar_finance_rate}} — the household is paying the equivalent electricity price of {{solar_effective_rate}}, compared to the average grid rate of around {{grid_rate}}. Solar panels are expected to last {{solar_panel_life}} years, with warranties of a similar length, meaning the system well outlasts any loan used to finance it. And a battery adds resilience, keeping essential appliances running during outages.
EVs are far cheaper to run, require little maintenance and aren't exposed to volatile global fuel prices. Plus they're quiet, comfortable and fun to drive! Switching from a petrol to an electric medium SUV saves {{ev_suv_savings}} on bills over 15 years, or around {{ev_annual_savings}} every year, including road user charges. Diesel ute drivers save even more at {{ev_ute_savings}} net over 15 years.
{{location}} drivers cover an average of {{driving_weekly_km}} per week: well within the range of a modern EV. And charging is easy. 80% of EV owners do more than half their charging at home. 60% trickle charge using a standard three-pin plug. Charging at home using grid electricity costs effectively half what you'd spend on petrol or diesel, and for those with rooftop solar, the savings are even greater. And for when you do need to charge on the go, public chargers are available at least every 75km on 97% of New Zealand highways.
Heat pumps use around {{heatpump_energy_pct}} less energy than gas heaters to deliver the same warmth, and, unlike gas, they cool in summer too. Switching from an LPG fire to a heat pump saves {{heatpump_15yr_savings}} on bills over 15 years and {{heatpump_lifetime_savings}} over the lifetime including upfront costs, or around {{heatpump_annual_savings}} every year. Of {{location}}'s {{heaters_fossil}} non-electric heaters, approximately {{heaters_lpg}} are LPG. Whatever the fuel type, going electric brings significant savings, and the comfort upgrade is immediate.
Hot water heat pumps have a higher upfront cost, but deliver the lowest ongoing energy bills of any water heating option. In {{location}}, switching from LPG instant to a hot water heat pump saves {{water_15yr_savings}} on bills over 15 years, or {{water_lifetime_savings}} over the lifetime including upfront costs. Of {{location}}'s {{water_heaters_fossil}} non-electric water heaters, approximately {{water_heaters_lpg}} are LPG instant.
Water heating makes up around {{water_energy_pct}} of an average home's energy load — making it one of the highest-impact switches a household can make. Hot water heat pumps can also act as a 'thermal battery' where you time it to heat water when electricity is cheapest, or when your solar panels are generating.
Cooking doesn't use a lot of energy but electric cooking is lower cost (and much lower emissions) than cooking with gas. Induction is more expensive upfront than resistive electric cooking, but offers lower ongoing bills. Switching from LPG to induction saves {{cooktop_savings}} on bills over 15 years.
But the most compelling case for induction might be health. Gas cooking releases nitrogen dioxide and other pollutants into the home, linked nationally to 200+ premature deaths, 3,200+ child asthma cases, and $3.3 billion in productivity and health costs every year.
