Where to start for me to answer this question?
[I apologise in advance for the long written post, but I would appreciate if you read it through.]
South Africa has a major energy crisis.
We have ongoing widespread national power outages, which started in 2007.
It gets complicated to explain exactly how Loadshedding works, but it basically means that we can be without electricity between two to eight hours, on a daily basis, depending on the nations electricity demands and according to scheduled timetables.
Many to most (if not all) industries have had no choice but to invest in expensive large generators, and businesses have had to invest in UPS's (Uninterrupted Power Supplies) which consists of batteries to store up electricity for when the power goes out. (Imagine owning a supermarket or restaurant or a shopping mall with banks. Imagine owning an ice-cream shop.)
How this effects us on the home front, including everyone living in cities and the surrounding suburbs, is that we have had to adapt to living without electricity for short stretches of time. (Imagine preparing big sit-down dinners with the possibility of having no electricity to cook it with. Think of planning a work function for example, or a milestone birthday party or graduation or even a wedding.)
During the Covid-19 Pandemic, working from home meant that one had to get a UPS in order to have WiFi (and even then sometimes the Internet might be down). (Imagine trying to home school children with sporadic Internet.)
Everyone here now has some form of solar power; from big solar panels covering the roof, to solar powered mobile phone charges, to solar powered radios, flashlights and reading lamps.
Everyone here now has gas bottles for cooking (or just to boil water for a cup of tea or coffee).
Can I live without electricity? Short term answer is yes; we South African's have sort-of being doing it on-and-off for 18 years... long term answer is a definite no; it is just not possible living in an urban environment, relying on pumped in water supply.
Edited to add: Think of us driving to work without functioning traffic lights; think of ambulances trying to get to hospitals; think of our hospitals and operating theatres... it is part the reality we are in with our energy crisis.
Edited again to add: The upside to Loadshedding is all the romantic candlelight dinners.
