Smart meters, which measure your energy consumption, are a great way of keeping track of how much energy you''re using. When you can actually see how much carbon you''re wasting every time you switch on the TV

or make a cup of coffee, it will make you think twice. The Home CO2 meter is a portable monitor you can take from room to room to see at a glance which appliances are using the most electricity.Each year the average UK household spends: 36 running a tumble dryer 27 running a washing machine 70 on lighting 40 operating a dishwasher 30 powering a basic computer 60 running a fridge-freezerIn the UK each year, stereos on standby cost 290m, and produce 1.6m tons of CO2 and TVs on standby cost 88m and produce 480,000 tons of CO2.For every pound saved on an electricity bill, you''re also saving 6kg of carbon dioxide, which is what a coal-fired generating plant would emit while making this much power.The energy meter does not require you to carry out any electrical wiring. The clip fits on the external cable, which has a live supply running through.

If you have any doubt about any connection or how to install it consult a qualified electrician.
