How Can We Do It?
• Geothermal• Ocean power
– Seawater A/C– Wave Energy– OTEC
• Next big thing?
![Page 16: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/16.jpg)

‘Interisland Wind’
• Wind farms on Lanai & MolokaiCastle & Cooke &
First Wind Hawaii each agree to initial 200 MW projects
• Hawaiian Electric planning facilities & operations to integrate 400 MW of wind power on Oahu •State of Hawaii to plan, permit & contract building of inter-island cable
Similar submarine cables in service (Cross Island Cable, many others)
![Page 17: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/17.jpg)
17
Transportation solutions
Initiatives must include:– mass transit – all modes– more fuel-efficient vehicles– cleaner alternative fuels– more personal mobility (walk,
bike)
• Rapid adoption ofPlug-in Electric Vehicles
![Page 18: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/18.jpg)
18
Electrifying transportation• 1/3 of imported oil in Hawaii used for ground
transportation• Driving an electric vehicle (hybrid or plug-in)
is cheaper (≈1/3 cost) and cleaner (less CO2) than internal combustion engine vehicle
• Hawaiian Electric working – Better Place; Phoenix Motorcars; Idaho National
Laboratory (hybrid conversion to plug-in hybrid) for HECO and MECO; other EV and equipment manufacturers
![Page 19: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/19.jpg)

Your Bill
• Advanced metering to give you more control
• Time-of-use rates for off-peak savings • Greater savings:
– Solar, energy efficiency & conservation
![Page 20: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/20.jpg)
20
Bottom Line
• Bills more predictable than with oil • Total energy cost (electricity &
transportation) lower using RE in place of oil & gasoline
• Hawaii becomes national leader– Increasing energy independence– Reducing fossil-fuel use– Limiting greenhouse gases
![Page 21: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/21.jpg)
21
Opportunity to Lead• Island people under- stand sense of
limits• Island people have strong
environmental empathy • Hawaii has trade winds, strong
sunlight, other RE resources
• Hawaii can model a low-carbon and totally modern lifestyle
![Page 22: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/22.jpg)
22
What We Need
• Leadership• Laying down our arms• Sense of urgency• Speaking the truth
![Page 23: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/23.jpg)
23
Two Simple Words
• LESS– Energy efficiency, conservation, wise use of
resources
• LOCAL– Use our local resources, all of which are
renewable and have lower carbon emissions than using coal and oil for 90 percent of our energy

Our dependence on oilWe depend on imported fossil fuel (mostly oil, some coal) for over 90% of all energy – jet fuel, synthetic natural gas, gasoline, and electricity
Oil has challenges:– Security of supply– High cost
– HECO’s oil price up171% from 1996 to 2006
– Environmental impact – Clean air – Clean water– Global warming

Refining oil
• Light, quality products first
• Diesel• Gasoline• Residuals
(bunker and LSFO)

36
Oil is refined for many uses
Each barrel is refinedfirst for jet fuel, then gasand marine fuel.
What’s left, the goopcalled “residual,” is usedto create electricity.
An “integrated” energy system
![Page 37: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/37.jpg)
37
Two myths about renewable energy
• “There is a ‘Silver Bullet.’”‘OTEC is all we need.’ ‘One big solar farm could power all Oahu.’‘Nuclear energy is the answer.’
• “Wind, sun are free; RE should cost less than fossil fuel energy.”At first no. In the long run, as oil gets more expensive, RE prices should be more stable -- and probably cheaper.
![Page 38: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/38.jpg)
38
Energy Storage
The greatest technological challenge to achieving the Hawaii Clean Energy Initiative may be finding a way to store utility volumes of renewable
electricity and move it from when it is made to when it is needed.
![Page 39: Hawaiian Electric: Helping our State Achieve the Goals of the Hawaii Clean Energy Initiative](https://reader035.fdocuments.in/reader035/viewer/2022062703/55503165b4c9059f318b4e8c/html5/thumbnails/39.jpg)
39
Pumped-storage hydro
• Pump water to upper reservoir during non-peak period (overnight)
• Hydro-electric operation during peak demand period
• Overall efficiency about 70%
• Turns irregular ‘as available’ renewable energy into firm energy for peak periods

Biodiesel
• Higher energy yield than
ethanol
• Made from vegetable or animal oil: palm, jatropha, soybeans, peanuts, canola, kukui, coconut -- ALGAE
• Feed stock can be imported or grown locally

Greening our existing assets
• New Unit at Campbell Industrial Park– 110 MW peaking unit -- 2009– RFP for 100% biofuel supply
• Longer-Term Initiatives– Studying biofuels for steam boilers– Planning algae for biodiesel feed stock
demonstration using power plant CO2
