Many New Zealand homes still rely on fossil fuels to heat their water, keep the place warm, cook their food and get around. A surprisingly large chunk of New Zealand’s emissions can be linked back to these ‘dinner table decisions’, but these fossil fuel machines could be upgraded tomorrow with more efficient electric equivalents and fuelled by rooftop solar, batteries and the grid.

This would save most New Zealanders money and slash our country’s emissions and that’s why our mission at Rewiring Aotearoa is to electrify as many of them as possible by 2030. Our research uses averages to show overall trends and our electrification guides need to be broad to help as many people as possible.

We realise every household has different energy needs and will be at a different stage of their electrification journey, so these averages and general advice may not be relevant to everyone's situation. Some households drive less. Others use more hot water. But this calculator makes power personal and even offers some helpful advice (you can find out how we calculate the results here and if you have any questions email us).

So plug in your numbers and see the savings.
