The minister woke up one morning and said 24.
Or he saw it on a licence plate. 24. Even. Round. Easy to say twice and remember.
Or he asked the consultant. The one who knows everything. The one who was behind a shawarma grill last year and sits on four committees this year.
None of that happened. And that is the point.
Last month the Ministry of Electricity sent the usual message. Feeders failed. Two areas lost power. Set the air conditioner to 24 or higher.
They have been saying 24 every summer since 2019. And in 2024 they stopped asking and started cutting, two hours a day, across forty areas. So it is not a slogan.
Two weeks earlier, New York asked the same thing. Set your air conditioner to 78.
78 Fahrenheit is 25.6 Celsius. Kuwait asked for the colder room.
Kuwait says 24 because that is what the buildings were built for.
When an engineer designs cooling for a building here, he assumes 45 degrees outside, 55 on the worst day, and 24 inside. That last number decides everything. The size of the ducts. The power of the unit. How much cooling the building can produce when it matters.
So the ministry is not asking you to suffer. It is asking you to use the machine at the setting it was designed around. Below 24, you are asking the building a question it was never built to answer.
New York says 78 because that is what the research says is comfortable.
The number started in 1979 as an emergency order during the oil crisis. It was cancelled two years later. But it stayed, because the science caught up with it.
ASHRAE, the American engineering body, spent decades studying how people actually experience temperature. Their comfort range for summer runs from about 22.5 to 26. Both 24 and 78 sit inside it.
And every degree you raise the thermostat saves roughly one to three percent of your cooling bill. That was measured, not guessed.
Two countries. Two completely different reasons. One and a half degrees apart.
Does it work?
Kuwait’s campaign took 30 megawatts off peak demand in 2025. Real. Also about 0.2 percent of a peak near 17,600 megawatts.
New York asked and still had outages.
Not nothing. Not enough.
Because 24 is the cheapest thing a government can do and the only thing it can do this afternoon. The real answers are power stations, insulation, better compressors, and houses that do not leak. Those take five years and billions. 24 is what you do while you wait.
Now the part that matters.
Ask Kuwait where 24 came from and there is a building code. Ask New York where 78 came from and there is a comfort standard and an energy calculation.
You can disagree with both. You can say 24 is too generous for a country heading toward 19,000 megawatts. You can say 78 is an old American number the rest of the world has no reason to inherit.
But you can argue, because there is something to argue with.
That is all evidence-based decision-making means. Not being right. Just being able to point at where the decision came from.
Now count how many decisions we live under can do that.
The requirement that changed. The circular that reversed last year’s circular. Ask for the study and you get a name. Ask for the name and you get a title. Ask for the title and you get a committee. Ask about the committee and you find the man.
Last year he was selling shawarma. Or he was a حارس عمارة. Then someone knew someone, and now he is a consultant. The salary is 180. The allowances are ten times that, because the salary is for the job and the allowances are for the meetings, and there is always another meeting. He has never opened a building code. He does not need to. He has an opinion, a seat, and a signature down in the corner as two ugly tiny initials.
His number becomes policy exactly the way 24 did. The difference is that when you ask where it came from, there is nothing at the other end. Just him.
A number from research can be wrong and still be honest, because it tells you how it got there. A number from a chair is right until the chair changes.
24 is not correct because it is 24. It is correct because someone can show you where it came from.
Ask a number where it came from. The good ones answer.
Fun fact. Setting the air conditioner to 16 does not cool the room faster. The machine removes heat at one fixed rate. No setting makes it work harder. All 16 does is keep it running past the point where it would have stopped.
