The Pacific International Center for High Technology Research
(PICHTR) (http://www.pichtr.htdc.org)
is an independent, not-for-profit, applied research and development
center incorporated in Hawaii with an international board of directors
from the United States, Asia, and the Pacific Region. PICHTR's
mission is to assist private businesses and government agencies
in their efforts to advance sustainable development and improve
the quality of life throughout the Pacific Region.
This report presents a summary of the use of renewable energy in the state of Hawaii since 1980. It includes an overview of the renewable generation capabilities found throughout the state, and an effort has been made to briefly describe the history and status of every renewable energy facility in the islands that has made a significant contribution to the reduction of Hawaii's importation of fossil fuels, including some facilities that are no longer operational. Tables of data on the renewable energy savings for each island and for the state in total are also presented. These tables attempt to show the actual contribution that every particular renewable technology has made to the islands. The amount of oil saved by the use of renewable sources of energy presented in these tables considers estimates made of the specific heat rate (BTU/kWh) of each island's utility as well as the average BTU content of the typical barrel of fuel burned in the island's power plants. The price of this saved oil has also been tabulated so that a presentation can be made of the money that has consequently not been spent on petroleum over the years due to the use of renewable resources. A separate table of the annual energy values of the power exported by the state's sugar companies on each island has also been included so that the statistics in this report may be used to analyze renewable energy consumption either with or without consideration of the sugar plantations own power use. Finally an appendix is included which contains an explanation of the methodology used to evaluate the contributions made by bagasse and solar water heating. Sample calculations are include to illustrate the technique used to obtain the presented values and to highlight whatever assumptions need to be made in calculations of this nature.
