We're moving Aotearoa towards a sustainable energy system that supports the wellbeing of current and future generations.
Energy in New Zealand
About 40% of New Zealand's total greenhouse gas emissions come from our energy use.
The choices we make about how we use energy in our everyday lives and businesses have an impact. Our opportunity is to build out a strong and stable energy system by prioritising energy efficiency, energy conservation and the use of renewable energy sources.
With clean and clever energy we can achieve emissions reductions, lower energy costs, make our homes warmer and healthier, and contribute to a reliable and resilient grid.
How we make an impact
-
Regulation of products, processes and systems
Our regulations and standards mean New Zealanders have access to and are encouraged to use the best performing new products and technologies available internationally, including vehicles – for home, commercial and industrial use, saving money and energy.
-
Information and motivation to promote clean and clever energy choices
We provide evidence-based information and motivation to New Zealanders and businesses to help them make informed clean and clever energy choices – lowering energy bills, improving productivity, and future-proofing for a clean and secure energy economy.
-
Targeted investment and support across the energy system
We use our expertise to facilitate and catalyse targeted investment and support that addresses significant, evidenced market barriers for the adoption of clean and clever energy technology.
Electrifying our roads
