This article discusses Hawaii's energy conservation efforts. Faced with high electricity costs, the Hawaii Department of Education instituted a pilot program in which schools could earn back half the amount they saved in electricity over the course of a semester. As a result, one school's electricity use decreased by more than 10% for the 2007-2008 year and its power bill dropped by almost $8,000, which meant the school got back close to $4,000 to use for any purpose. With the incentive program now implemented throughout the statewide school district, officials in Hawaii are hoping that other principals will be just as diligent about cutting energy costs. While many on the U.S. mainland--concerned now about heating costs this winter--cannot necessarily relate to Hawaii's balmy climate, the state's broad approach to energy use may provide some lessons that can be applied in other states and districts.
