IDT Energy Explains Appliance Electric Usage

refrigeratorWhen a product is labeled “300 watts” this information tells the consumer what the maximum usage the appliance will ever use. For instance a refrigerator only uses its maximum, let’s say 300 watts, or close to it, when the compressor is running. When the fridge is quiet it is then using much less electricity, perhaps only 5 watts just to run any electronics it might have.  Many appliances whose settings change or are periodically on/off will be using different amounts of electricity at different times. Appliances like these are stereos, which use more watts set at higher volume, or use more electricity to open/close the DVD door. Calculating the amount of electricity these types of appliances use will be the subject of a future post.
