Using the list of some typical appliances listed below calculate the energy usage based on how long you used the appliance/energy using device. If you use your refrigerator 48 hours during the audi t you would multiply (.114 cents per kWh (rate) x 48hr (time used) x 125 watts (energy use/M)) + .006/hr(capital cost) x 48 hrs. This translates to .68 in operating costs and .28 in capital costs or a total energy estimate of .96 units.
