energy is to paper as batteries are to film

So in the digital world will energy become the new paper? like batteries were to film when photos went digital? http://ti.me/1eIZyuG 


i remember when we sued to have film. That was when your picture taking would stop because you ran out of film. Then I got a digital camera. Then picture taking would stop when I ran out on batteries. Still running out of something.
Is the cost of the world becoming digital increasing demands for energy? Will that energy be limited?
