“By 2020, Hawaii aims to generate 20% of its energy from non-fossil fuels” (Brown et al. 2008, 11). According to the National Renewable Energy Laboratory (Arent et al. 2009, 1-2), oil accounts for 90% of Hawaii's energy consumption and 75% of their electricity. Because Hawaii has no pipelines or oil fields, it is forced to import oil to meet its energy needs (Arent et al. 2009, 1). Hawaii is disconnected from the rest of the United States, which means it must provide its own energy needs (Croucher 2010, 79). How can alternative energy sources reduce the need to import oil? Hawaii's geography is optimal for making use of biofuels, solar and geothermal resources (Brown et al. 2008, 27). The focus of this document will be on three alternative energy solutions: 1. Biofuels, 2. Solar energy and 3. Geothermal energy. Biofuels will be divided into biomass, ethanol and biodiesel. Solar energy will be divided into solar systems, residential solar and passive solar systems. Geothermal energy consists of geothermal power plants, geothermal water heating, and heat pumps. How could biofuels reduce Hawaii's dependence on oil? Speaking about biofuels, Koh and Ghazoul (2008, 2452) stated: “In its simplest analysis, biofuels are considered carbon neutral because all the CO2 released during the combustion of biofuels is offset by carbon fixation during plant growth” . Hawaii is perfect for biofuels because according to Tran et al. (2011, 1757), “The Hawaiian Islands have several agroclimatic regions with a year-round growing season and relatively large arable lands.” This allows for the cultivation of a variety of energy crops in Hawaii.
