This is an amazing idea! One of the biggest strengths of this game is that it allows players (who want to) to create their own narrative. Over the years in dayZ I've seen so many amazing examples this, and judging by how many RP servers there are out there, many others feel the same way I do. Just having the option of turning on streetlights/power lines would be fantastic. Sure, most people in RL don't know the first thing about doing it, but if most of the population turned undead, getting lights at night would be high on the list and we'd figure it out pretty quick. :)
