According to the ENERGYSTAR calculator, if every student, staff, and faculty member at JTS replaces just one 60-watt incandescent bulb with a fifteen-watt CFL, we will reduce electricity use by an estimated 58,400 kWh per year. Each bulb will last for five years, as opposed to six months with a regular bulb.
