It's code that you must have outlets every so many feet, regardless if 12V / 5V appliances are more efficient. Even then you still need to be familiar with code to run low voltage wiring. Things like

- How high outlets and switches must be off the floor

- How close to plumbing / ducting wires can be and where you can run them

- Which areas need GFCI

- How to hammer in a wire staple securely without damaging the insulation (harder than it sounds)

- How to divvy up circuits and pick appropriate gauge wire

- How to wire n-way switches

This stuff is not idiot-proof, even at low voltages. If you get it wrong, your house burns down and insurance won't pay out. In my experience it's better to have a master electrician lay out the circuits and give advice while you do the grunt work of routing and pulling runs. Let them handle the panels, wiring switches, outlets and lights, and listen to their stories (most electricians have some good ones)
