Industrial society is built around technology, and that technology needs a constant supply of energy. This article takes a look at what would happen if that electricity supply stopped.
A darkened room, its walkways dimly illuminated by emergency lighting and the displays of monitoring equipment, rumbles with the vibrations of cooling systems injecting chilled air towards hot processors and spinning disks. The shrill sounds of thousands of data storage devices fill the air, alongside the cooling systems; the relentless blinking and trilling of green lights goes on as data is sent and received through miles of copper and glass fibre. Clunk. Warning sounds – alarming cries from dumb systems that only know that something has failed. In a wink the UPS takes up the load, drawing power not from the high voltage mains, but from deep tanks of diesel embedded in the lower levels of this data centre. Management is notified and the call goes out for emergency supplies of liquid fuel: the contract says there is to be no interruption, and the fuel suppliers are on standby 24 hours a day. The fuel suppliers are receiving further calls, from a standing start they experience a tide of demand as throughout the city the power fails: data centres, hospitals, offices, government buildings, military installations – who gets the fuel first? Who gets the last reserves?

Her clock is blank; no light seeps in through the blinds from the street; her fumbled attempts to switch on the bedside lamp were to no avail.

She pulls her way down the remaining steps and picks up the telephone, her breath is short – there is a tone, the telephone company keeps the system running through its own generators. She dials 9…the keypad is soundless. She hangs up then brings the receiver to her ear – nothing; the gentle burr has gone as the last diesel dries up at her local exchange.
