Big-box stores could help slash emissions and save millions by putting solar panels on roofs. Why aren't more of them doing it?

Jasmine Graham was quoted in CNN:

Jasmine Graham, WE ACT's energy justice policy manager, said the potential of building rooftop solar on big box superstores is encouraging, only "if these projects use local labor, if they are paying prevailing wages, and if this solar is being used in a manner such as community solar, which would allow [utility] bill discounts for folks that live in the same utility zone."
