in a city that has electricity cuts almost every day.

Why does it cost so much energy, then?
Well, other people have figured out how much
energy
the human brain and that of other species costs, and now that we knew how many neurons each brain was made of, we could do the math.
So the total energetic cost of a brain is a simple, linear function of its number of neurons, and it turns out that the human brain costs just as much
energy
as you would expect.
So the reason why the human brain costs so much
energy
is simply because it has a huge number of neurons, and because we are primates with many more neurons for a given body size than any other animal, the relative cost of our brain is large, but just because we're primates, not because we're special.
They just can't afford the
energy
for both a large body and a large number of neurons.
We calculated on the one hand how much
energy
a primate gets per day from eating raw foods, and on the other hand, how much
energy
a body of a certain size costs and how much
energy
a brain of a certain number of neurons costs, and we looked for the combinations of body size and number of brain neurons that a primate could afford if it ate a certain number of hours per day.
Well, if our brain costs just as much
energy
as it should, and if we can't spend every waking hour of the day feeding, then the only alternative, really, is to somehow get more
energy

Cooked foods are softer, so they're easier to chew and to turn completely into mush in your mouth, so that allows them to be completely digested and absorbed in your gut, which makes them yield much more
energy
in much less time.
So because of cooking, what once was a major liability, this large, dangerously expensive brain with a lot of neurons, could now become a major asset, now that we could both afford the
energy
for a lot of neurons and the time to do interesting things with them.
With this large brain now affordable by cooking, we went rapidly from raw foods to culture, agriculture, civilization, grocery stores, electricity, refrigerators, all of those things that nowadays allow us to get all the
energy

energy
and how rapidly they work.

energy.
Well, the impact
energy
depends on the square of the velocity times its mass, and the mass depends on how big it is and what it's made of.
