@miriam98 - Sometimes you take for granted how important the power engineering technology behind the electrical grid system is, until you get a power outage.
I lived in Asia for four years, in a small town that was quite susceptible to electrical outages. Fortunately we lived a simple life while over there so it didn’t really inconvenience us too much.
What was worse was when I came to the United States, and I found myself getting outages in the area I lived in, sometimes several times a year. Now that was inconvenient!
They usually resolve the outage within a matter of hours but in worse case scenarios it might take a day or so, just enough time to let the meat in the refrigerator start to spoil.
