New Zealand Consumption

New Zealand's Consumption

While we don't consume the most, we still get through a lot of energy

Energy helps us do our kiwi thing  - it powers and heats our homes and workplaces, and transports us and our goods around the country and out into the world. Almost half our energy is used for transport alone, and a quarter of our energy usage is in the form of electricity. Let's take a closer look.

 

New Zealand's energy mix

New Zealand's energy mix

1

New Zealand has the third highest rate of renewable energy as a portion of primary supply in the OECD (after Norway and Iceland). 40% of our energy comes from renewable sources.

While we rely heavily on renewables, such as hydro, geothermal and wind to produce our electricity, 60% of our energy still comes from fossil fuels.

In fact, we use around 45 million barrels of crude oil every year - that’s more than 1,200 litres of crude oil per person, per year. Together, that is enough oil to fill the Wellington Regional Stadium (the 'Cake Tin') around 12 times.

We also use 4.5 billion cubic metres of natural gas - the equivalent of an additional 800 litres of crude oil per person per year.

Where does our energy come from?

3

Our energy is supplied by a mix of renewable, and non-renewable sources.

New Zealand Total Primary Energy Supply (TPES) is generally measured in petajoules (PJs). Our TPES is the total amount of energy available for use in its raw state. A petajoule is a recognised measure of large quantities of energy.

It is worth noting that our primary energy supply (900PJs) differs from our actual consumption of energy (573PJs) by over 300PJs. This is because a portion of our primary energy supply (around one third) is used up in the process of 'transforming' it from an initial raw state (like geothermal steam energy) into a useable form (electricity). Significant quantities of energy are lost in the process of energy transformation and in the distribution/energy management process.

The 60/40 Split

Right now, 60% of our energy supply comes from oil, gas and coal. Renewable energy sources supply 40% of our energy needs.

This is the hightest proportion from renewable energy since records began. New Zealand had the highest renewable primary energy supply in the OECD after Norway and Iceland in 2014.
