LBNL's 2004 Low Power Study

The final report for our study of low power mode consumption in California can be found at:

Some highlights:
* Low power consumption is over 100W of average consumption in the typical house
* This is over 15% of state residential consumption
* Over 2/3 of this is electronics

We took an expansive definition of low power and included Ready modes (because power management could often drop these to sleep modes after a period of time, e.g. on a VCR), and single-mode products (e.g. a surge protectors and GFCI outlets).

We also incorporated the time dimension of low power modes to exclude any consumption while the device was active or disconnected. Our core figure of merit is an annual average low power mode power consumption level.

A follow-on project to refine this estimate is supposed to begin shortly.
