It seems like everything comes with a clock these days. Coffee makers, microwaves, VCRs and TVs can all tell time. So can digital thermostats and every radio ever invented. And while time is an essential element of the core function of many of these appliances, gadgets and tools, do we really need all of these blinking timekeepers? Take a quick look around your home and get rid of any unnecessary clocks. Unplug and de-battery those that are superfluous in order to cut your energy use. Besides, you can always check your wristwatch or cell phone if you're super curious.
