I think people are jumping to the conclusion that this is Electro's default state. Who says they weren't filming scenes in which Electro uses his powers, and they wanted to use some practical make-up to help add to the CGI effects of him releasing the electricity. It's easy to make judgements based on the pictures released, but putting a little thought into it helps a bit.

This might sound lame but it's my honest answer:
As a film major and in general a passionate film enthusiast I'd use my new found power to break into the film industry and stop production on all the unnecessary film reboots and remakes. I'd probably pepper in original ideas here and there so the studio execs would pursue new creative avenues instead of rehashing old ones, and often disgracing the legacy of the films that came before it.
Simple perhaps, but that's the route I'd take.
