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.

Scientists have developed a high-current density water-based battery that can be suitable for residential use. The next-generation “flow battery” could help households store rooftop solar energy more safely, cheaply, and efficiently than ever before, according to researchers. . Photovoltaic water pumping systems (PVWPS) are a promising solution to improve domestic water access in low-income rural areas. PSH complements wind and solar by storing the excess electricity they create and providing the backup for when the wind isn't blowing, and the sun isn't shining. When supply exceeds demand, water is pumped uphill; when demand rises, it flows back down through turbines to generate electricity. H ow can we generate clean energy only when it's needed? With a “ water battery,” known worldwide as a “ water pump battery ”.
