Our homes account for 10% of New Zealand’s energy-related emissions.

Using less energy at home can save you money on your power bill, and leads to better health outcomes and reduced greenhouse gas emissions.

Our focus on homes

Energy is a vital part of our lives at home, keeping us warm and powering everything from our appliances to hot water.

The energy used in Kiwi homes comes mainly from our highly renewable electricity system, but we're still reliant on fossil fuels to ensure we have enough power at peak times. 

Improving the energy efficiency of Kiwi homes not only reduces emissions, it ensures whānau can enjoy warm, dry and healthy homes – without increased energy costs.
