Energy efficiency key action to meet renewable energy goals

EECA modelling shows nationwide uptake of energy efficient technology could significantly reduce the cost of meeting New Zealand’s ambitious renewable electricity goals.

The study shows the savings from system wide uptake of modern technologies like LEDs, heat pumps, energy efficient water heating and electric motors could provide the system with the equivalent of 4,000 GWh of extra capacity, before any new renewable generation would be required.

EECA’s Chief Executive Andrew Caseley says the usual mind set is to build more renewable generation, but investment in energy efficient technology is often overlooked.

‘Energy efficient technology is a key solution hiding in plain sight. Mass uptake of these technologies would lead to significant electricity demand reduction and savings in factories, buildings and houses, so they would effectively play the same role as new renewable capacity.’

Energy Matters to Climate Change

September 2018

EECA’s short video ‘Energy Matters to Climate Change’ shows the relationship between our energy use and greenhouse gas (GHG) emissions, as well as the opportunities to reduce carbon at home, on the road and in business.


EECA’s chief executive Andrew Caseley says many New Zealanders know “we’ve got a lot of renewable electricity, but the reality is that we’re still heavily reliant on fossil fuels to meet a lot of our energy needs, particularly in transport and in industry.”
Mr Caseley says big changes are required to move New Zealand to a low-emissions economy, and that will require “every one of us to make a difference where we can.”

Transition to a low-carbon economy for New Zealand

April 2016

This report, produced by the Royal Society of New Zealand, takes an in-depth look into climate change mitigation options for New Zealand. It finds that many mitigation options are already well-understood and achievable. Achieving a low-carbon economy for New Zealand involves taking low-risk climate mitigation actions now and planning for more ambitious greenhouse gas emissions in the future.
