caroline stuck: lanai: the model for sustainable enterprise

Lānaʻi“The Model for Sustainable Enterprise”

Sustainability on Lanai•Existing projects (Solar, electric

cars, limu project, wind)

•Future projects (Desalination, organic farms)

•Possible projects (Solar thermal, wastewater treatment plant, green roofs, fish farms)

•90% of energy needs depend on fossil fuels

•Renewable energy goals at 70% by 2030

Existing Projects

•Solar

•Wind

•Electric Cars

•Limu Project

Solar• Photovoltaics (semi-conductor technology to directly convert sunlight into

electricity)

• Requires sunlight to produce energy

• Popular energy source

• 18-43 cents per KWh

• Most expensive renewable energy source

Electric Cars

•Power station at central office

• Brought in by Ellison

•Laboratory for sustainability.

Wind

•Controversial issue

•25% of the island

•No benefits for Lanai

•Ideal location

•New owner plans for wind to be on a community scale

Limu Project

•Northern coast of Lanai

•Restoration efforts have been difficult

•LHES students take part in efforts

•$20,000 grant

Projects Coming Soon

•Desalination Organic Farms

Desalination•Lanai’s largest sustainability

project

•Water supply to be brackish, not ocean

•Solar power to convert salt water into fresh water

•More fresh water, more sustainability projects

Organic Farms•Drip-water irrigation systems

•Hope to export produce to primarily Japan

•Vast amounts of open land

•Previously largest pineapple plantation in the world

Possible Projects

Solar Thermal

• Uses mirrors to concentrate sunlight

• Only produces heat

• Stores energy in various mediums

• Potentially generate power 24 hours a day

• 19-35 cents per KWh

Green Roofs

• Cost effective

• Combines wind and solar

• Alternative to large farms

• Can be done on an individual level

Fish Farms

• Draws on traditional practices

• Proposed to be located north of Kaumalapau

• Perpetuates native Hawaiian fish

• Provides a reliable supply of seafood

• Take advantage of Oceansphere technology

•No impact on the enviroment

Wastewater Treatment

• Water-recycling system

• Solve sanitation problems on the island

• All natural multistep biological digestion process

• Water becomes clear and odor free

• No extra septic tanks or plumbing

My Impression

•Sustainability projects are necessary

•A combination of projects increases the likelihood of success

•Not one is better than the other

•Creates a positive attitude

The Overall Goal

• Create a 100% self sufficient island

• Fully sustainable future

• Reducing overall costs of living

• Set a green example for the rest of the world
