The invisible fragility of our seamless modern life

Living Without Electricity - Professor Roger Kemp · 40:53 · Video: Gresham College · Watch at the source

In short: We assume electricity is a constant, but our society has built a house of cards on its reliability. When the power fails, it isn't just the lights that go out; it is our ability to pay for food, navigate cities, and communicate with one another.

In December 2015, Storm Desmond caused unprecedented flooding in North Lancashire and Cumbria. The River Lune burst its banks and swamped an electrical substation, leaving more than 61,000 homes and businesses without power for six days. This event served as a stark demonstration of how modern city life has become inextricably linked to the grid.

Professor Roger Kemp of Lancaster University highlights that while individual dependencies—like Wi-Fi boxes or credit card readers—might seem obvious, the collective loss of systems is what shocks people. Over the last 20 years, we have traded physical backups for digital convenience: paper timetables are now online, handwritten phone lists have been replaced by SIM cards, and cumbersome keys have given way to electronic hotel locks.

The consequences of these dependencies are profound. When electricity vanishes, mobile coverage, internet access, and television disappear. Electronic payment systems fail, preventing people from accessing cash at ATMs, while petrol stations must close because their pumps require power. This reveals a transition where government services—from car registration to tax payments—have moved almost entirely online.

While the British electricity system is considered very reliable by international standards, it is impossible or prohibitively expensive to guarantee 100 percent reliability under all circumstances. The Lancaster experience suggests that as society becomes more dependent on the internet and electricity, we must develop robust contingency plans for those rare moments when the lights go out.
