Low-price Energy Meters at Aldi

One step to saving energy at home is to know where your electricity is going. From Saturday (while stocks last) Aldi have these energy meters for $14.99.


To me that sounds like a good price, I got mine for $30 a few years ago, and (from the picture) this one looks to have much the same functions.

If you get one, here's how to convert the reading (in Watts) into a more meaningful number, like financial cost.

Dollars per year = Watts x hours of use per week x 0.052 x 0.25378
The last number is the price of electricity in dollars, which may differ depending on where you live.

PS. The Aldi sale appears to be an energy theme - there are also LED bulbs available again.
