Is New Zealand a net importer of energy?
New Zealand is a net importer of energy but has a high degree of energy independence with a self-sufficiency index of 73% in 2023. While it exports coal, gas (in the form of methanol) and oil, electricity and biomass supply is indigenous and refined petroleum products are imported.
How is energy used in New Zealand?
Total energy supply (TES) includes all the energy produced in or imported to a country, minus that which is exported or stored. It represents all the energy required to supply end users in the country.
What resources does New Zealand use?
While it exports coal, gas (in the form of methanol) and oil, electricity and biomass supply is indigenous and refined petroleum products are imported. About 30% of New Zealand's total energy consumption is derived from renewable sources, a notable contrast to the 12% average observed among OECD member countries.
How much does New Zealand export?
In macroeconomic terms, New Zealand's total exported goods represent 15% of its overall Gross Domestic Product for 2024 ($283.9 billion valued in Purchasing Power Parity US dollars). That 15% for exports to overall GDP in PPP for 2024 compares to 14.3% for 2023.
