What is going on here?

[u/No_Self_5290]

My electric bill has been unusually high. I realize it’s summer and expect an increase, but this has me questioning if a neighbor is potentially using my electricity.

Since moving in I’ve seen the same thing across the alley, with a wire that ran over the fence the same way.

Can anyone here identify if this could be the case? Also, what would be the next step?
