The document provides an overview of Hawaii's energy sources, highlighting that 80% comes from petroleum, which is non-renewable and imported, contributing to pollution. It discusses alternative energy sources like solar, wind, hydrogen, and wave energy, each with their own pros and cons, emphasizing the potential for significant savings and environmental benefits through renewable resources. The Hawaii Clean Energy Initiative aims to meet 70% of the state's energy needs by 2030, encouraging conservation and community involvement.

1. Local Sustainability

2. Overview
• In this presentation, we will discuss:
- Hawaii’s main energy source
- Alternative energy sources available to
Hawaii
- Pros/Cons of each energy source

3. Did you know?
80% of Hawaii’s energy comes from petroleum.
Petroleum:
is abundant (so far).
is easy to use.
proves to be more
efficient in terms of
transportation.
However, petroleum:
is not renewable.
is expensive.
is not produced in
Hawaii meaning it
needs to be imported.
emits carbon dioxide.
creates pollution

4. By switching to renewable energy resources,
Hawaii citizens can save up to $200 billion.
(Phillips et al., 2003)
What can WE do?
• Conserve energy by:
• Turning off lights when not
in use.
• Car pool, catch the bus, walk
or ride a bike
• Unplug appliances and other
products when not in use.
• Finding other ways to
improve energy use in daily
life.
What is being done?
• Hawaii Clean Energy
Initiative:
– “Conserve: Use what we need
efficiently”
– “Convert: Harness what we
have wisely”
The aim of this initiative is to
meet 70% of our energy needs
by 2030.

5. Alternative Energy Resources
• Solar
• Wind
• Hydrogen
• Wave

6. Solar Energy
‘energy harnessed from the sun’
Pros
• Sunlight is abundant in the
islands of Hawaii.
• Renewable
• Lowers electricity costs
• No carbon emissions
• Environmentally friendly
Cons
• Intermittent. Access to
sunlight can be limited.
• Requires space: the more
power you need, the more
space you need.
• Exotic materials: some solar
cells require materials that
are expensive and rare.

7. Wind Energy
‘extracted from wind using wind turbines’
Pros
• No toxic emissions
• Renewable
• Costs are relatively low
• Can be used almost
anywhere
Cons
• Wind is inconsistent,
unsteady and
unpredictable.
• Turbines may be harmful to
wildlife

8. Solar and Wind Energy
… could theoretically meet all of
Hawaii’s energy needs.

9. Hydrogen
‘chemically oxidating H2 to make energy ‘
Pros
• Hydrogen is the most
abundant element in
the world.
• Renewable
• Fuel efficient
Cons
• Expensive.
• Highly flammable,
hazardous.
• Storage can difficult and
transportation is pricey.

10. Wave Energy
‘transportation and capture of ocean waves to create
electricity’
Pros
• No toxic emissions.
• Waves are predictable.
• Easily accessible in
Hawaii
Cons
• Not practical in every
location in Hawaii.
• Harmful effect on
marine ecosystems near
it.
• Relatively new, needs
more research.

11. WHAT NOW?
– Share your knowledge of renewable energy
sources available to Hawaii.
– Reduce, reuse, and recycle.
– Join groups or organization that support and aim
to promote a more sustainable lifestyle.
Get involved
