The meter reading belongs to no one

Column: from the perspective of a student in a house where nobody has ever seen the energy bill.

In the average student house, energy is invisible twice over. The bill is folded into the rent, so nobody feels it. The meter hangs behind the bikes, so nobody sees it. Invisible plus belonging to no one: that is, in miniature, exactly the recipe on which waste thrives everywhere, from student kitchens to office towers where the floors stay lit all night for nobody.

The antidote costs ten or fifteen euros: a plug that measures.

Let such a device travel around the house for a week and discoveries follow. The games console that is "off" but keeps drawing ten to fifteen watts in standby, day and night, all year, over a hundred kilowatt-hours for the pleasure of booting up two seconds faster. The elderly fridge that single-handedly consumes more than all the laptops in the house combined. Phantom load costs an average household hundreds of kilowatt-hours a year; in a student house, with a lot of equipment per square metre and nobody feeling like an owner, likely more. A few smart plugs with a schedule, after midnight everything genuinely goes off, easily save 100 to 200 kilowatt-hours a year, which is 30 to 70 kilos of CO2 and several tenners nobody has to give up.

And then the light bulbs, the least exciting advice of this century, skipped by everyone for precisely that reason. Replacing one forty-watt halogen bulb with a five-watt LED saves, at three hours of use a day, thirty-eight kilowatt-hours a year. Per bulb. A student room easily holds five. The LED itself outlasts the average degree, extension included. Which bulbs and metering plugs are currently being watched is tracked by Risegoods; it doesn't require much study.

The real return, meanwhile, never shows on the meter. Whoever has once seen what a console consumes in standby looks differently at every meter cupboard for the rest of their life, in the first home of their own, at the office, perhaps one day in their own company. The energy transition mostly needs people who can see energy, and that education starts not in a lecture hall but at a wall socket.

For the next house meeting there is thus a nicer agenda item than the cleaning rota: which appliance in this house is the biggest silent consumer? Everyone gets a guess. One week of measuring names the winner, and want to bet it isn't the washing machine?
