Biogas offers a homegrown solution for New Zealand’s energy future
New Zealand is rich in renewable energy, but managing supply — especially during peak demand periods — remains a challenge. Fortunately, there’s a local solution that’s already gaining traction: biogas made from food and agricultural waste. By embracing a circular economy, where organic waste is recycled into energy and fertiliser, we can strengthen our electricity and gas grids, reduce emissions, and build long-term resilience — all while turning waste into value.
Biogas takes off: how the world is embracing renewable gas
Biogas is a renewable energy source that comes from organic waste. Almost any organic waste product, from food scraps to crops to human sewage, can be turned into biogas. It doesn’t create any additional greenhouse gas emissions, making it a net zero emissions gas.

Good energy @ work: Closing the Gap
As we approach International Women's Day on March 8, we are reminded of the incredible strides wāhine have made in Aotearoa from gaining the right to vote in 1893 to having our first female Prime Minister in 1997. The talent amongst our wāhine spans across all disciplines, including sports, arts, culture, and beyond.
Renewable energy the key to data centre success
Everything we do online relies on data centres. When you store or access something in ‘the cloud’, you’re really storing it in a data centre somewhere in the globe. Data centres house huge networks of computer servers that, together, can store billions of gigabytes of information.
The future of biogas
There’s huge potential for biogas in New Zealand – from energy to waste to agriculture, it can make a big contribution to our emissions-reduction efforts.
