EECA Chief Executive, Mike Underhill, explains the New Zealand context and why EECA is interested in motivating change. He provides a brief introduction to energy use and supply in New Zealand and how behaviour change will have a major impact on these sectors. A range of examples of the types of interventions and campaigns that EECA is currently doing are provided. Mike believes that behaviour change is the key to unlocking potential and with behaviour change alone, we can get a 20% improvement in energy use in New Zealand. However, he also realises that this is the hardest thing to change.
