Metre Your Energy


The voices have an energy consumption metre that sits on top of the television and lets them know how much energy they are using.  The energy metre has different modes that tells them how many kilowatt-hours they are using, what that is in grams of CO2, and how much it’s costing them.

The voices say that this is an excellent way for them to tell instantly if they have left something on somewhere or something is draining a lot of energy.

So what do the little numbers mean? The metre shows that over an hour us beans averaged at .300 kilowatt-hours that in turn produced about 200g of CO2. If you multiplied this for a year then that’s just over a third of the total CO2 produced by the average household*. That doesn’t sound too bad, does it? The problem is, this is just worked out as an average for the last hour’s energy, which was at the lowest rate of consumption i.e. two beans with lights on, a computer and a stereo. If you factor in cookers, kettles, washing machines, tumble dryers and hoovers the average starts to go up.

Look at what happens to the metre when they put the kettle on:



The voice says we are going to watch what our consumption is this week and tell you what it is next Saturday, then we’ll try to reduce it each week, or at least keep it the same.


Wish us luck!

    It’s always good to know how much energy one’s really using. It’s really easy to forget things like turning off lights when you’re not using them, or switching off the power to the computer when you’ve finished with it. But it’s worth thinking about.
