How Much Electricity Do You Actually Consume? by Wallie(m): 2:50pm On Aug 15, 2012
The goal of this thread is to sensitize people to how much electricity appliances they own consume per month.

There are a few assumptions that I have to make to make the calculation possible.
1. I would assume that you pay NGN 11.30 per kWh (1 unit).
2. That your appliances are on for 1 and 4 hours a day, respectively.

NOTE: The calculations below are just estimates of what a typical appliance consumes and your actual appliance may vary but it should be too far off.

Since I can’t really post spreadsheets and tables of the actual calculations, I’ll try to post it in a way that will still be meaningful.


EDIT:

Attached Excel spreadsheet

Well, since I have the spreadsheet already, I can easily change the scenarios. If I assume that you have power for 10 hours per day, an average user's consumption might look like this:

48" Ceiling Fan ----------------------- 75 ---------- 11.3 ---------- 10 ---------- 31 ---------- NGN 262.73
