Earthshine is even more faint because the moon's "albedo" (a specific kind of reflectivity) is less than Earth's. Even though this dim light is only a reflection it can still illuminate some features of the moon. Earthshine can be best seen during the crescent phases (the 1-5 day period before or after a New Moon).
I believe we probably could if we use a cleaner source of energy such as solar power. It's renewable and almost unlimited.
Hope this helps you! :D
Some of this you have to do on your own
Persian Gulf is the answer
