No, it's really inefficient. In order to be useful for power generation, the three square mile circle it illuminates would have to be completely full of solar panels in order to capture all the energy being reflected. And it it's as bright as the moon, that's about one half millionth as bright as the sun. So those solar panels, assuming no cloud cover, will be operating at one millionth the efficiency of daytime.
Meanwhile, battery technology, particularly for terrestrial power storage, keeps getting better and better. This has zero potential to offset CO2. Which is deeply sad for the science fiction geek in us all, but honestly, right now solar generation technology is starting to feel pretty science-fictiony, so maybe that's okay.
