Funny, it's like this thread was tailor-made for me. I have a physics and electronics background, and my first career move was with a mineral exploration geophysics (resistivity and magnetometer surveys).
If you are creative and ambitious, really good at what you do, and focus on applied geology/geophysics, and specifically exploration, and try to avoid dependency on the academic publicly funded "vacuum" side of geology (except as it increases your knowledge in an applied field), your knowledge and ingenuity can translate to real power, and you can make a LOT of money.
If you have geology as a major with a minor in electrical engineering (NOT electrician, but actual electrical engineering), your value as a geologist skyrockets, as you become a specialized breed. Even if you don't apply your knowledge as an entrepreneur, your value to firms like mineral exploration EQUIPMENT companies cannot be underestimated.
Minerals of all kinds are becoming increasingly scarce as an exponential trend that has been maturing for some time, so there really is no shortage of opportunities in applied geology and geophysics.
Hence, I like the suggestion that said "can't you do both?". You can. Simultaneously -- and you multiply your fall-back opportunities.
The thing I consider the most important of all is the quality of life, over and above security or average income for a field. Being an electrician is hard work, and electricians, for as much as they can make, are not that scarce, given that the requirements to work in that field open it up to a lot more competitors. On top of that, the work really is, by and large, mundane. Plus, if you're not planning to be a contractor with employees, ways to multiply or have a vested interest in anything you do are limited. You'll just be trading time for money.
My opinion, were I in your position:
Geology/geophysics (Masters), with a minor (BSEE) in electrical engineering. Do that and you're solid gold, set for life.
