Renewable Energy in New Zealand

A large amount of New Zealand’s total primary energy supply (TPES) comes from renewable resources. Currently, New Zealand has the third highest renewables percentage of TPES (38%) in the OECD. Iceland has the highest, followed by Norway.

In 2013, a total of 75% of electricity generation came from renewable sources, the fourth highest in the OECD.

Hydro, geothermal, wind and bioenergy are used to produce electricity in New Zealand. For more information on electricity generation see section ‘F. Electricity’ of Energy in New Zealand.

New Zealand is a country rich in geothermal resources because of the many volcanic areas, and faults and tectonic features. As geothermal fluid is much lower in temperature than steam produced by coal or a gas boiler, the transformation efficiency to electricity is much lower. The efficiency is around 15%, and for this reason geothermal energy supply only produces 14.5% of New Zealand’s electricity even though it contributes to over half of the renewable energy supply.
