It's a very basic tip that we follow and we keep the blinds or the curtains on in summers during the sunny days to keep the sun out of the house and it prevents unnecessary heat to stay out of the house and we can adjust with a fan or cooler or Air conditioner at a normal temperature and not putting extra load on it with a very low and that saves money because of less electricity bill.

I suppose the reverse of that is, if you keep your curtains and blinds open on cold sunny days, it can help to heat up your house and save on heating costs.

We keep our blinds open normally during the daytime in dry seasons to get fresh air instead of using the Air Conditioner. We save electricity costs with this.

Usually we do this because in hot areas we can't pass days with direct sunlight in rooms. We usually use curtains to prevent direct sunlight at room, and obviously it maintain the room temperature.

The blinds staying open allow us to get good sunlight which is a substitute for using electrically powered lighting in our houses. We keep our prepaid electricity meter off during the day.
