What's on the other end of that plug?
Is it a solar panel or a windmill?
Looks like "Energy Reality" needs to upgrade their sockets for the commom three-prong plug that is used today. Assuming, of course, that it wants to be properly "grounded".
....solar panel or a windmill?"
Let's not forget who we're dealing with.
Most likely it going to be two AAA batteries.
AAA batteries are proven and more reliable!
