This video by Technology Connections talks about how window awnings can greatly help cool your home.
Another thing I want to add is that window awnings can protect windows. We get pretty big hail here, and (wood or aluminum) awnings can save your window glass. I have also heard of “Clamshell Awnings” which are on hinges, so you can remove the poles and lower the awning to cover and protect windows in extreme weather.
Lastly, here are some old window awning ads for your entertainment (from Wikimedia commons)
