A fridge runs about half the time with out opening the door. Opening the door many times a month might add about 30 hours to the regular run time of the fridge. 30 hours of running a fridge costs about .90 dollar. If you open the fridge about 10 times a day for a month that would mean you open the fridge 90 times.
so each opening of the fridge probably costs about .001 dollars. or 1/10 of a penny.
Its inserting very hot items or leaving the door open for a long time while deciding what to eat that will cost more.
obviously refrigerators run less in the winter unless you heat your house irregularly high and they run more in the summer.
And again the price will be a bit more for each door use in the summer as the temp escaping in to the fridge when you open it is hotter.

∙ 10y agoThis can be only calculated by knowing what the wattage draw of the fridge is and what the utility company charges you per kilowatt hour. To find the wattage multiply the amps times the volts of the fridge. To find the kilowatt/hour you are charged, look on your utility bill or call the company and ask what you are charged per kilowatt hour.

Is it really true that when a refrigerator is open for so long the electricity will increase?
Yes. The refrigerator is set to hold a certain temperature, that's probably cooler than the environment where the fridge is sest. When you open the door, the cold air will leak out, so the fridge will start working to get the temperature down again. If you were to shut the door the temperature inside would drop rather quickly, and the fridge could stop working for awhile. But as long as the door is open, the temperature will remain high and the fridge will keep working. And as long as it's working it will be using up electric energy.
Thermal Dynamics If you leave the fridge in your kitchen open for 10 minutes after an hour is the room warmer or colder than it would have been had you not?
A fridge works by transferring heat from within itself and dumping it into the room around it. if you leave the door open then the heat gets back in again through the open door meaning you waste a lot of energy doing nothing. when the door is shut the fridge will pump heat out into the room raising it's temperature slightly. you can feel this heat coming off of the back of the fridge. when you leave the fridge door open then the temperature difference will try to reach equilibrium causing the room to cool slightly again. Horse Isle Answer: Slightly warmer

What uses more electricity keeping a fridge door open for a while or constantly opening and closing it during this time?
Every time you open your fridge door - or indeed your freezer's door - it allows cold air to fall out onto the floor of the room. If this is allowed to happen for more than a few moments the thermostat inside the fridge or freezer, sensing that too much cold air has gone, will turn on the fridge's motor and compressor pump to cool down the new air. The more the compressor pump and its motor are forced to run unnecessarily, the more electricity would be used, with the consequence that the money to pay for that electricity would simply be wasted. Knowing those "facts of life" it should be easy to understand why it is better to keep the door closed as much as possible instead of leaving it to hang open for more than the short time it takes to load or unload food from the fridge.

Does having the window open at home while the air conditioner is on cost you more?
If you are trying to cool your home or room to a temperature that is lower than the temperature outside, then the electricity needed will be much greater if the window is open. So, in short, yes.AnswerOn a warm day, leaving your windows open will allow warm air to replace the air that your air conditioner just worked to cool. Thus, your air conditioner will have to continue to run, which uses electricity, to re-cool this air. Of course, using more electricity will cost you more money.

Controllable cost versus uncontrollable cost?
A controlable cost is a cost a manager can control. For example, if I am in charge of HR at a company, the dollars I spend on advertising open positions is a controlable cost. An uncontrollable cost, would be, the price my business pays for electricity.
