Plug into a more sustainable form of energy

At least 80% of our electricity demand is met from renewable resources such as hydroelectricity, wind and geothermal energy. This is one of the highest rates in the world.




How New Zealand generates electricity

  • Hydro electricity is generated by driving water from rivers or dams through turbines.
  • Geothermal captures underground heat and steam by tapping into wells several kilometres deep.
  • Wind turbines generate no carbon emissions when in operation. The infrastructure is easy to build and remove compared to hydro and geothermal.
  • Thermal electricity is generated almost entirely from high-emissions fuels – gas and coal.

Using electricity efficiently reduces our emissions

While 80% renewable is a great achievement, we currently have to top up the rest by generating electricity from coal and gas, which generates climate-changing carbon emissions.

Using our electricity more efficiently allows our renewable sources to go further. It also frees up capacity in the electricity system. This means more electricity is available at a cheaper cost, so it becomes more viable to switch from high-emissions fuels such as petrol and coal to electricity.

If more New Zealanders switched to energy efficient technology, such as LED lighting and heat pumps, we could significantly reduce the cost of meeting New Zealand’s climate commitments and speed up the transition to a low-emissions economy.
