A typical 15-year-old refrigerator consumed about 1,700 kilowatts of electricity, for an average annual cost of $136 based on a cost of eight cents a kilowatt-hour
Electricity is sold in kilowatt hours in typical residential settings. A range of costs is from about 10 to 15 cents per kw hr.
Question: How much electricity does a typical American home use? In 2007, the average monthly residential electricity consumption was 936 kilowatthours (kWh).Last updated: February 6, 2009 http://tonto.eia.doe.gov/ask/electricity_faqs.asp
A typical iron uses 1000 watts all the time the heating element is working. It is controlled by a thermostat so the element might be on for a quarter of the time. In an hour the iron might consume 250 watt-hours or 0.25 of a unit.
Yes. These are typical properties of nonmetals.
There is plenty of equipment that goes in a typical kitchen, including: microwave, refrigerator, dishwasher, garbage disposal, sink, etc.

In the U.S. today, the average refrigerator in a typical home provides between 18 and 26 cubic feet of storage space. For an average family of four, 19-22 cubic feet is common. These figures combine both the refrigerated compartment and the freezer compartment. When shopping for a refrigerator, keep in mind that larger refrigerators and freezers, use more electricity and consequently cost more to operate. A refrigerator is one of the biggest users of electricity in most U.S. homes.

Water will freeze at 0 degrees celcius. A typical refrigerator will be set to about 4 degrees.
Refrigerators should be set at 40°F maximum.
there are many factors affecting COP. maybe it ranges from 2.5-5

It's adjustable. It should be about 40 degrees F ... I prefer about 38.
A typical person should consume 2,000 calories a day
It was like a typical rural life before electricity arrived in most of the villages in 1970s. Electricity has totally changed their lifestyle and now no village is left in Pakistan without electricity.
It depends COMPLETELY on the temperature (and humidity to a lesser extent) outside the refrigerator. If the ambient temp is below - say 40 degrees - the inside temp of the refrigerator, then it need not be on at all. If its hot enough than it won't be able to stay cool inside even if it runs continually.
An electric device does not "use up" electricity, but rather energy. And strictly speaking, it doesn't "use up" energy, but transforms it from one form to another. It is common to say that energy is used up when it is transformed to less concentrated forms--when it is degraded. Electrical energy ultimately becomes heat energy. In this sense it is used up. ------ I have a washing machine - I think it's a typical appliance - it uses electricity and water. But it does not "use up" any electricity or water - there is always more. Same for all of our other appliances. The clothes washer (above), dryer (gas and electricity), dish washer (water and electricity), microwave (only electricity). Popcorn maker (only electricity), toaster (only electricity), refrigerator (only electricity). Really, what these appliances "use up" is counter or floor space, especially the big ones.
