Do you know what powers your aluminium?
Producing just one tonne of aluminium requires approximately 13–14 MWh of electricity. With that much energy involved, the source of the electricity matters.
Depending on where aluminium is produced, the smelting process may be powered by coal, gas, or renewable energy such as hydroelectricity.
At New Zealand’s Tiwai Point smelter, aluminium production is powered predominantly by renewable electricity from the South Island.
For architects, builders and homeowners, choosing NZ-made isn’t only about where a window or door is assembled. It’s also about understanding the energy, manufacturing capability, and supply chain behind the aluminium itself.
