Step 3: Prepare the Spreadsheet. In this tutorial, we will create a very simple macro to change the color, size and boldness of text. In your spreadsheet, type in some text in any of the cells. We will later record a macro to change the formatting of this text.
The average cooling capacity of a dorm fridge is somewhere around 150 BTU/hr, that is, it is capable of moving 150 BTUs of heat in 1 hour, regardless of how efficient (or inefficient) it is in terms of energy usage.
The power consumption of domestic fridges is typically between 100 and 200 watts. Over a full day they are likely to use around 1 to 2 kilowatt-hours (kWh). Old domestic refrigerators and commercial refrigerators consume much more. The actual energy consumption of your fridge or freezer will depend on many factors.
