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.

While 80% is a great achievement, we currently have to top up the rest by generating electricity from coal and gas, which produces climate-changing carbon emissions. Using electricity more efficiently will reduce our reliance on fossil fuels.

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.

Electricity efficiency reduces our 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.

What EECA is doing

  • Co-funding

    We provide co-investment and support for businesses and the public sector to use energy more efficiently. We also provide insulation and heater grants to help low-income homeowners save energy at home.

  • Motivating people

    Our Gen Less brand encourages consumers and businesses to reduce energy-related emissions by using electricity and other types of energy more efficiently.


  • Regulating

    Through the Equipment Energy Efficiency programme, we ensure products sold in New Zealand meet minimum energy performance standards. Energy efficiency labelling regulations also help consumers make better choices around energy efficient products.
