Use blinds to keep summer heat out and let winter heat in

Why

Winter and summer the sun can pour a lot of heat into our buildings.  In the winter, that is great.  Let the sun in.  In the summer, that overheats our buildings or makes our air conditioning run longer.

How

Instead of overheating or cranking up the air conditioning, close your blinds or curtains to keep the sun out in the summer.
