It's a device you plug into the electrical outlet. It's got a receptacle of its own into which you plug an appliance. It displays the voltage, current, wattage, peak wattage use, peak current drawn, KWh, a timer, and even the cost of the electricity used since the timer started.
That is very interesting.
Could you provide more information about this product.
I would be interested in running similar tests.
A benchmark that is becoming more and more prevelant is cpu performance per watt.
AMD processors use much less energy and also run much cooler than Intel procs.

From the above link.
Power Consumption
We'll start with power consumption - the contenders? A 90nm Athlon 64 3500+ vs. the Pentium 4 630 and the dual core 2.8GHz Pentium D. As always, we measured total system power at two states: idle and under a full load. For our full load test, we used a multithreaded application, 3ds max 7, performing the CBALLS2 render test from the SPECapc benchmark.
The K8 architecture simply lends itself to lower power consumptions than Intel's high frequency approach to computing with the Pentium 4 (especially Prescott). The move down to 90nm really reduced AMD's power consumption a lot, to the point where the 90nm Athlon 64 3500+ actually consumes less power under full load than the Pentium 4 630 at idle.
The Pentium 4 vs. Pentium D comparison is also interesting, as the 2nd core doesn't add all that much to overall system power consumption. In this case, we're looking at an increase in overall system power consumption by less than 15%. Intel still doesn't win in the power consumption department though; if you want something cool and quiet, AMD is still the way to go.
