- WORDS SCOTT DUTFIELD

Whether it's during a pivotal movie moment or as you're just about to hit submit on your essay, power cuts seem to happen during the most inopportune moments.

According to the US Energy Information Administration, Americans experienced an average of around five-and-a-half hours of electricity interruptions in 2022. These disruptions can be down to all manner of causes, from simple supply issues to natural disasters.
