Talk about
• Smart Thinking
– Innovation
• Being Strategic
• Ideas from New Zealand
• Other peoples ideas
• Looking out
4
Innovation
Ideas beyond your “Box”:
5
Enlarge the box
• Expose yourself to other peoples ideas
– Work out how the ideas might apply
– Use them
• Develop your own innovative solutions
6
Looking beyond the box
• Go and find others ideas
7
Develop ideas beyond your box
• Creative thought
• Original innovation
8
Implementable ideas
Moving Innovation Along
• Visionaries
• Entrepreneurs
9
Moving Innovation Along
• Crises
• Political Imperatives
– This was so for Geothermal Energy in New
Zealand
10
Desire for Security of Supply
• In New Zealand - Post world war two
• Electricity demand growing rapidly
– Growth rate of 6% per annum
• Significant investment in hydro power
development
• Two dry hydrological years
– 1947 and 1948
• Running out of electricity became a
significant political issue
11
Political Issue
• Drove a focus on indigenous resources
– not reliant on imported energy
• Drove innovation in geothermal energy
– Technology to drill and research to harness
liquid dominated geothermal resources
• Government funded initial exploratory
drilling, undertook research, underwrote
risk, etc …...
12
The NZ Geothermal Success
• Well developed frameworks
– Planning and Permitting
– Environmental
– Health and safety
• A stable platform for long term investment
• Geothermal has become a significant
contributor to NZ’s electricity generation
• Wide open opportunities for more direct heat
use

Wide Open to Direct Heat Opportunities
• Geothermal Direct Use Targets
• These are under review

Business Sector (p18)
17
Value in Strategy ….
• Even though New Zealand has been using
geothermal energy since the 1930’s …..
And industrially for 60 years …..
• More needs to be undertaken to foster direct
geothermal use in NZ
