These figures serve as rough estimates, and the actual power consumption of your appliances may differ significantly. To obtain precise measurements, check the power tags or use tools such as a clamp-on ammeter or a home energy monitor like a Kill-A-Watt meter. These meters are commonly available at hardware stores or online. Multiply the average daily usage hours by the wattage provided below to calculate the watt-hours consumed per day.
Keep in mind that certain items, like garage door openers, may only be in use for a fraction of an hour or minute each day. For example, a 300-watt item used for 5 minutes daily will consume only 25 watt-hours per day. In cases where a range of numbers is provided, the lower figure often indicates a newer and more efficient model. The notation "NA" denotes appliances typically powered by non-electric sources in a photovoltaic (PV) powered home.
If you're considering generating your own power, it's highly recommended to invest in a true RMS digital multimeter, a clamp-on ammeter, or a Kill-A-Watt meter. These tools are invaluable for understanding energy usage patterns, whether you're producing power or not.

Note: TVs, Computers, and other devices left plugged in but not turned on still draw power.
**To estimate the number of hours that a refrigerator actually operates at its maximum wattage, divide the total time the refrigerator is plugged in by three. Refrigerators, although turned “on” all the time, actually cycle on and off as needed to maintain interior temperatures. |
