Discussion
I think my experiment went very well but if I could do it again, I would work out how much exactly it would cost per year on stand by. I would manage my time a bit better aswell. One thing I noticed was that even though there are no lights or anything that are used on stand by, it still draws a lot of power from the powerpoint.
Conclusion
Now that I have finished my experiment, I conclude that my prediction was in fact correct and Stand by uses a lot more than we expect. From now on this has urged me to be more power conscious at home.

Equipment/Materials:
9 different appliances
Electricity reader
Powerpoint plugs
Method:
1. Choose 9 appliances, three from each category of your choice

So what is your question? Contrary to popular belief, any electrical appliance that is plugged in but not turned on does NOT draw any power. On the other hand many appliances do have a “stand by” or “memory back-up” mode that does draw power when the item is not being used. In most cases this is measured in mili-amps, so it takes a bunch of them to run up ones electric bill.
