All people need some form of energy every day, at least for cooking their food, and in most modern houses, also for preserving their food.

In my case, that energy must be provided as electricity, or else I would starve.

Other people might be able to substitute something else for electricity, e.g. they might have access to a forest, to collect wood and burn it for cooking, and they might make food reserves that can be kept at the ambient temperature, e.g. pemmican.

Those people might not need electricity, but they are not less dependent of an energy source for staying alive, than the people who need electricity every day.

I certainly use less electrical energy every day (less than 200 W average power for the entire house) than the energy that would be consumed by someone burning wood for the same purpose.

The people who do not cook at home and are not less dependent on electricity or another source of energy for staying alive, they just pay someone else to cook for them, while consuming the same energy elsewhere.
