DIY home energy monitor
Once I wrote a short article about energy monitors which can be used in home to reduce energy consumption. Here is another one - EnerJar. The winner of the Greener Gadgets design competition the EnerJar offers a simple way to monitor energy consumption for device connected to it and can be made by yourself. If you have heeded hardware (including a jar), electro technology knowledge and a little patience go ahead. Otherwise it might be better just to buy Kill-A-Watt.
