Continuing with the theme of gadgets that help you live more sustainably, here are some more ideas for consideration.

The efergy energy saving meter is a wireless electricity meter that tracks your energy use so that you know exactly how much you are consuming at any given time, what it is costing you and an estimate of your personal contribution to climate change.  The data is stored so that you can track the trends and changes in energy consumption in your household.  Easily installed by complete novices. Costs around £45.

You can save about £50 a year by using an EcoButton on your PC or laptop.  When you press the EcoButton you put your machine into eco-mode to save energy until you come back to it and press the button again to reactivate it where you left off.  Expect to pay around £15 per button.

The Bye Bye Standby energy saving kit works by totally cutting power to the devices plugged into it when they’re not in use, saving power that devices would have consumed on standby.  You get one remote control and three sockets for £34.99 and one remote and two sockets for £19.99.
