I wonder why don't they use mirrors to reflect the light back at night time.
Metallized PETF film is strong enough, very lightweight, and not expensive, while reflecting, say, 95% of the light.
Could save them a lot in electric bills.

Anyway, the necessary mechanical systems exist and are produced/deployed at scale.
Maybe US regulators should step in and require light / heat shielding at night above a certain size.
