Electricity is definitely planned. Though such a huge impact that it will take some time until implemented.
But the problem is... your game might have focused on electricity. Though it looks (to me) clunky, blocky, unnatural.
RW had the focus on a more realistic look and the building system. Both was very well achieved. And now its working on a reason to build (other than to realize your imagination) - survival.
Electricity will be definitely the cherry on the cake, i am sure of that. But for now the game is focussing on survival to give the world the feeling of really being alive anda ctive. Also to give a challenge.
