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.
A modern EnergyStar refrigerator uses less than 100 watts for cooling. The light bulbs associated with opening the doors will double the load. A recent EnergyStar report states that a 2007 refrigerator consumes between 1 and 2 kWh per day.2 kWh Ã· 24 hours = 83 watts average load. modern EnergyStar refrigerator uses less than 100 watts for cooling.
