Yeah was going to comment that this is a heavily American perspective and possibly even a heavily American city dwelling perspective.

Lots of countries even where electricity is cheap use awnings as it's just better to not need to cool something down if it can be avoided.

My childhood home in WA (Western Australia) had awnings, along with shade trees and a patio and it made a huge difference. noticed especially where the west facing Window got setting sun in summer and had no awnings
