Save money by reflecting sun away from windows

"When you are faced with unwanted heat coming through
windows, yes, you can buy lots of different things on
the market to keep the heat out. But if you go to the
camping section at your discount store, for approxi-
mately $1.98 you can buy a solar camping blanket, all
folded up. One blanket will do three typical windows
and reduces heat by 40 percent or more, making the
house dramatically cooler. If you use air condition-
ing, this makes it work less hard. I did put a piece
on the exterior of my window air conditioner to repel
the heat, and that helped it work without so much
effort. "
