The rapid buildout of solar, and the rise of efficient air cons for electric home heating certainly makes it seem like a much less wasteful technology than before. I still think though that people are severly underestimating the effectiveness of relative simple, low-tech options like awnings though.
I live in sweden and I am baffled by how uncommon awnings are. In my home country window shutters that also work as yawnings are quite common, especially in places without AC. My partner was downright insulted when I suggested getting some blackout curtains to reflect sunlight back outside when the sun is hitting our living room. I eventually won that battle after the first summer.
You can also get UV-absorbing film for the windows, though it'll make things worse in the winter.
