Short-rotation forestry for energy production in Hawaii
- Univ. of Hawaii, Honolulu, HI (United States)
In Hawaii, imports of fossil fuels continue to accelerate and now provide over 90% of the total energy supply at a cost exceeding $1 {times} 10{sup 9} annually exported from the local economy. Concurrently, sugarcane and pineapple crops, the traditional mainstays of the state`s economy, have declined such that as much as 80,000 hectares of agricultural land are now available for alternative land uses. The feasibility of short-rotation forestry for sustainable energy production on these former sugarcane and pineapple plantation lands is being evaluated using species- and site-specific empirical models to predict yields of Eucalyptus grandis, E. saligna, and Leucaena leucocephala, a system model to estimate delivered costs, and a geographic information system to extend the analysis to areas where no field trials exist and to present results in map form. The island of Hawaii is showcased as an application of the methodology. Modeling results of methanol, ethanol, and electricity production from tropical hardwoods are presented. Short-rotation forestry appears to hold promise for the greening of Hawaii`s energy system and agricultural lands for the benefit of the state`s citizens and visitors. The methodology is readily transferable to other regions of the United States and rest of the world.
