Want to make your home more energy-efficient but are not sure where the biggest savings could be made? Want to go off-grid but you don't know how much energy each of your appliances and gizmos use? Is replacing that aging fridge worth it? Here's a gadget that might be useful to help settle these questions: Kill-a-Watt. You just plug it in the power outlet, plug into it whatever it is that you want to test et voilĂ ! The first step toward conservation is having feedback on how much you consume. Kill-a-Watt is not quite perfect: Having an easy to read power-meter that tells you how much everything (individually and together) inside the house consumes in real-time, as with the so-called intelligent houses, would be better, but K-a-W has the advantage of being inexpensive and better than the nothing that most people have. "LCD display, cumulative killowatt-hour monitor, displays volts, amps, watts, Hz, VA, forecast your costs, 0.2% accuracy," says the manufacturer. You should be able to find it online between $15 and $25. You can see photos of the insides here. ::P3 International: Kill a WATT ::Via WorldChanging
