Country
New Zealand
New Zealand has a diversified energy mix, with significant production of both hydropower and geothermal. As the country embarks on an ambitious energy transition, it has many natural advantages, including a strong renewable resource base. New Zealand already has a low-emissions electricity system, with over 80% of electricity coming from renewable sources. The key challenge will be to decarbonise other end-use sectors through clean power and support investments in new technologies to achieve deeper emissions cuts across all sectors. Notably, the transport sector accounts for the highest share of emissions and is almost entirely dependent on oil while…

…and outdoor living environments with comfortable temperatures and humidity levels, and improved air quality. Key facts Energy efficiency measures have been linked to improved health, such as fewer respiratory illnesses.Targeted energy efficiency programmes can reduce doctor and hospital visits and save health costs. In New Zealand, a retrofit programme led to a 43% reduction in hospital admissions for respiratory conditions, while a similar programme in Ireland reduced the frequency of doctor visits by 50%. Key analysis The World Health Organization estimates that household air pollution was responsible for more than 3 million deaths per year in 2020. Energy efficiency policies…

Oil security and emergency response
Ensuring quick and effective response to major supply disruptions Ensuring energy security has been at the centre of the IEA’s mission since its creation in 1974, following the oil crisis in 1973. Today, the global oil market remains vulnerable to a wide range of risk factors, including natural disasters, major technical accidents, and geo-political tensions. As oil is expected to remain a major component of global energy demand for the coming decades, particularly for the transportation sector,...

New Zealand funds 22 projects in emission-free transport
The Low Emission Vehicles Contestable Fund offers up to $6.5 million a year to projects that will accelerate the uptake of electric vehicles (EVs) and other low emission vehicles. The fund is administered by the Energy Efficiency and Conservation Authority (EECA). Projects are co-funded with private and public sector partners in areas where commercial returns aren’t yet strong enough to justify full private investment.It’s a Government fund administered by the Energy Efficiency and Conservation Authority (EECA). It’s one of several government activities paid for via a levy on petrol and engine fuels
