Users of the Force often refer to the "Light Side" and the "Dark Side". Is there any indication that there is an actual separation in the Force between these two sides, or do the terms just refer to moral/idealogical differences?

For example, force lightning is often thought of as a Dark Side power, given its destructive nature and that it is predominantly used by those on the Dark Side. But if, say, a Force user wanted to charge a de-powered droid with a jolt of electricity (and assuming force lightning would do the trick) would they be forced to actually tap into the "Dark Side"?
