NZ vs The World
How does Aotearoa's energy system compare internationally?
The Scorecard
NZ has a split personality internationally: world-class on renewable electricity, but still working on transport, industrial heat, and emissions intensity.
Rankings are indicative and based primarily on OECD and IEA datasets (2023–2025), not exhaustive global league tables.

Renewable Electricity
On this measure, NZ punches well above its weight. Only a handful of countries generate a higher share of electricity from renewables.
| # | Country | Renewable % | Main Sources |
|---|---|---|---|
| 1 | 🇳🇴Norway | 98% | Hydro (89%) |
| 2 | 🇮🇸Iceland | ~100% | Hydro (70%), Geothermal (30%) |
| 3 | 🇵🇾Paraguay | ~100% | Hydro (Itaipu Dam) |
| 4 | 🇨🇷Costa Rica | 98% | Hydro, Geothermal, Wind |
| 5 | 🇳🇿New Zealand | ~85% | Hydro (53%), Geothermal (20%), Wind (9%) |
| 6 | 🇧🇷Brazil | ~83% | Hydro, Wind, Biomass |
| 7 | 🇩🇰Denmark | ~88% | Wind (58%), Solar |
| — | 🇦🇺Australia | ~35% | Solar, Wind, Hydro |
| — | 🇺🇸USA | ~23% | Wind, Hydro, Solar |
| — | Global average | ~32% | Hydro, Wind, Solar |

Electric Vehicle Adoption
NZ is a fast mover on EVs — not Norway-level, but well ahead of most developed economies. Policy stability and fuel costs have helped drive uptake.

Electricity Prices
NZ electricity prices are above the OECD average — despite high renewable generation. Distribution costs, market structure, and network investments all contribute.
Residential Electricity Price (USD per kWh)
Prices shown are residential headline prices and include varying tax and policy components; comparisons illustrate relative position, not cost structure equivalence.
| Country | Price (USD/kWh) | Notes |
|---|---|---|
| 🇩🇪Germany | $0.40 | High taxes, policy costs |
| 🇩🇰Denmark | $0.38 | High taxes (~50% of bill) |
| 🇬🇧UK | $0.35 | Post-energy crisis stabilisation |
| 🇳🇿New Zealand | ~$0.24 | Above OECD avg, distribution costs |
| 🇦🇺Australia | $0.24 | Similar to NZ |
| 🇺🇸USA (average) | $0.17 | Varies widely by state |
| 🇨🇦Canada | $0.14 | Hydro-heavy provinces cheaper |
| 🇳🇴Norway | $0.12 | Abundant hydro, lower taxes |
| OECD average | ~$0.17 | — |

Emissions Intensity
Here's NZ's challenge: despite clean electricity, per-capita emissions are among the highest in the OECD. Agriculture — particularly methane from livestock — is the main driver.
Figures refer to gross GHG emissions (CO₂-e), including methane, excluding forestry offsets.
Total GHG Emissions per Capita (CO₂-e)
| Country | Per Capita | Main Driver |
|---|---|---|
| 🇦🇺Australia | ~21 t | Coal power, mining, transport |
| 🇺🇸USA | ~17 t | Transport, power, industry |
| 🇨🇦Canada | ~18 t | Oil & gas, transport, heating |
| 🇳🇿New Zealand | ~15 t | Agriculture (53%), transport |
| 🇩🇪Germany | ~10 t | Industry, power, transport |
| 🇬🇧UK | ~7 t | Heating, transport |
| 🇫🇷France | ~6 t | Nuclear power = low electricity emissions |
| OECD average | ~11 t | — |

Carbon Pricing
NZ was an early mover on carbon pricing, launching its Emissions Trading Scheme in 2008 — one of the first in the world. But prices and effectiveness have varied.
Carbon Price Comparison (2024-25)
Table includes both carbon taxes (fixed price set by government) and ETS prices (market-determined). Not directly comparable — taxes provide price certainty while ETS prices fluctuate.
| Jurisdiction | Price (USD/t) | Coverage |
|---|---|---|
| 🇸🇪Sweden (carbon tax) | ~$130 | Transport, heating fuels |
| 🇨🇭Switzerland | ~$130 | Heating fuels, some industry |
| 🇪🇺EU ETS | ~$70 | Power, industry, aviation, maritime |
| 🇬🇧UK ETS | ~$55 | Power, heavy industry, aviation |
| 🇳🇿NZ ETS | ~$35 | ~50% of emissions (excl. agriculture) |
| 🇨🇦Canada (federal) | ~$65 | Most provinces (being phased out) |
| 🇰🇷South Korea ETS | ~$5 | ~74% of emissions |
| 🇨🇳China ETS | ~$10 | Power sector (expanding) |

The Bottom Line
NZ's energy system has genuine strengths — but also real gaps compared to international peers.
🌟 Where NZ Leads
- Renewable electricity share (top 5 globally)
- Geothermal expertise and deployment
- EV adoption rate (top 10 globally)
- Early carbon pricing (ETS since 2008)
- Low-carbon electricity grid
⚠️ Where NZ Lags
- Agricultural emissions (world's highest per capita)
- Total GHG per capita (5th highest OECD)
- Electricity prices vs renewable share
- Energy security (gas decline, import dependence)
- Carbon price level vs EU/UK
Key Comparator Countries
| Country | Why Compare | NZ vs. |
|---|---|---|
| 🇳🇴Norway | Hydro-rich, EV leader, similar pop | NZ trails on EVs, prices lower in Norway |
| 🇮🇸Iceland | Geothermal pioneer, island nation | Similar renewable %, Iceland uses more geothermal for heat |
| 🇦🇺Australia | Neighbour, similar economy structure | NZ far cleaner on electricity, similar on transport |
| 🇩🇰Denmark | Wind leader, small advanced economy | Denmark leads on wind integration, NZ on hydro/geothermal |
| 🇮🇪Ireland | Similar GDP, island, agricultural economy | Both face agricultural emissions challenge |
