Lanai: Model for Sustainable Enterprise

  1. 1. L na iā ʻ“The Model for Sustainable Enterprise”
  2. 2. 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
  3. 3. Existing Projects • Solar • Wind • Electric Cars • Limu Project
  4. 4. 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
  5. 5. Electric Cars • Power station at central office • Brought in by Ellison • Laboratory for sustainability.
  6. 6. Wind • Controversial issue • 25% of the island • No benefits for Lanai • Ideal location • New owner plans for wind to be on a community scale
  7. 7. Limu Project • Northern coast of Lanai • Restoration efforts have been difficult • LHES students take part in efforts • $20,000 grant
  8. 8. Projects Coming Soon • Desalination Organic Farms
  9. 9. 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
  10. 10. 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
  11. 11. Possible Projects
  12. 12. 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
  13. 13. Green Roofs • Cost effective • Combines wind and solar • Alternative to large farms • Can be done on an individual level
  14. 14. 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
  15. 15. 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
  16. 16. 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
  17. 17. 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
