Sorry, I fixed it to "Almost every". I agree, "Every" is overstated.

I have never been to Karachi, what I know about Karachi, Karachi weather is not as harsh as Punjab or away from coastline so, you might survive (If you are used to living without AC) there without AC. And further, its hugely densely populate area so a lot of people might not have roof to install it. And Karachi gets people from the whole country and most of the people are living there temporarily, they might not want to commit on installing solar system on a rented house.

That might be reason, but numbers speak themselves. Source: [https://www.ceicdata.com/en/pakistan/electricity-generation-...]
