Problem: I need help collecting this data? Use nameplate data and energy bills to perform an energy audit for your residence. You should include all major appliances and their watt rating. If a watt rating cannot be found, then the device's voltage and amperage may be used instead. Also include computers, TVs, game consoles, and light bulbs. For all listed devices, then estimate its number of hours of usage per day, week, and month. You also need to gather your energy bills for the last 12 months to use in analysis. All this information will be used to conduct our analysis and to prepare your final report.
