Previously I posted a spreadsheet showing how much it in electricity it costs to operate certain items. The rates used to calculate the costs is based upon the rate per KWH at the time of the post. SRP changes it's rates four times a year. The rates increase in March, May, June, Sept., and December with the highest rate charged during months July, August, & Sept.
There is no way for anyone to determine the exact cost of any appliance. The utility company cannot tell you what it will cost to run an item. They can only tell you what it will cost to run an item 24 hours a day. It is how often and when we use each item that determines how much it will cost to run the item. As rates change so does the cost to run each item. An item that costs you lets say $30.00 a year may be cheap for how and when you use it today. However, as rates increase that item that seemed efficient today may become to costly to operate all together.
Here is where we get into problems, the higher the temp outside gets the warmer the inside temp gets resulting in air conditioners, refrigerators, freezers, ice makers, etc running more often. Then when it gets cooler these items will run less often and offset the cost when the hotter temperatures increase the cost. In theory this means it isn't the energy we use that is the problem but how we manage our money that is the problem. Especially, when the majority of one's yearly electricity usage is from all other appliances used in the home and not from air conditioners or heaters.
