> When I put the kettle on, I don't look at the meter.
I plugged in my kettle to my power monitor plug thing and saw how much energy it used.
I did this once as I knew that due to the nature of the world the kettle would use the same amount of energy to boil the same amount of water every time with only a variance in the initial temperature of the water. I only cared to look once and when I saw the "cost" I was like ooh great making tea is so cheap considering I only boil the kettle once in the morning.
