Both choices are very broad, and you could easily find work. With power and control, automation is a big thing (screw the working class), alternative energy sources, automotive, aerospace, nuclear weapons...

Girls... well you have to be born with the right equipment (doesn't matter in some countries, like the UK...). Women are easy, unless you are really picky about what you want to do...
