The power belt sander gets used quite often to remove the lower hull from a ship casting. It makes a lot of dust, but I get a better, truer surface more quickly than trying to sand it on a sheet of wet-n-dry.
Similarly, the disc sander gets pulled out and used when I'm shaping plexiglas cores for scratch built structures. Good square corners there.
The compressor for the airbrush is electrically powered.
I cut, rout, and finish my own bases -- circular saw, router, drill press used there.
I have a compact sander from a battery-powered toothbrush.
I have batteries in my digital calipers. Does that count for 'electric'.
Oh yeah, then there is the Dremel, but granted, using it to drill with micro-sized bits is asking for breakage.
Use the best available tool for the task at hand.
