Precisely this. I will give examples of US hotels since thats really the only first world country I have visited. Everywhere there's shades and basically with 4/5 lights I get no where near the light that a single no shade light gives in my own room. There are lots of things done in third world that are done in a more polluting matter for cost concern. But I would hazard a guess that if you take a ratio pollution / 'improvement of quality of living' first world countries would be so far ahead of 3rd world countries that there would be no competition. When I said countries I do mean most in that category there are bound to be exceptions.
