Want a quick way to save $50 on your electric bill? Stand-by power, also known as vampire power, used by cable boxes, stereos and printers costs about $50 each year even when they are off. To avoid these slow but costly leaks, use a power strip to centralize the plugs from these energy zappers. This way you can shut several of them off at one time and save that $50 for something useful.
