One gadget you may not be aware of is a smart-sensing power board. When it senses that one particular gadget has turned off (the "master"), it automatically cuts off power to other devices on the board ("slaves"). For instance, when you turn off your TV, it turns off the rest of your home-theatre equipment. This is also a good way to minimise the vampire draw in your house; that is, gadgets that remain on standby and sip at small amounts of power continuously.

There are quite a few of these in the market, from the likes of Belkin, Jackson and even generic brands.

If you prefer the manual touch, you can run remote power boards, once again from the likes of Jackson or Belkin. You can even get individual, remote-controlled power points, if you desire.

Finally, you may wish to look into a timer. If you know you'll only use certain implements at certain times of the day, or wish to limit how long a product can be used, then these can be incredibly useful.

While Belkin and Jackson only offer countdown timers with hard-set intervals, HPM and Arlec offer products that will allow you to set schedules, with HPM even offering a timer that can set different on/off schedules for each day of the week.
