Woah woah woah, is the entire world going back and applying things we learned in kindergarten? Are we really learning to share our things, and not centralise them? About time

I have to admit, this is a really good idea. Just expect waterway a to become packed with hydro-electric generators, which may be a good or bad thing. However, this for of distribution is a very good idea. It allows for people to make a bit more of an income on excess electricity, helps benefit the environment, and helps to minimise the disruption blackouts cause.
I support this, and I think it would maybe be a good time for you creative folk to start designing hydro, wind or solar energy producers, as you could make a killing if you can sell your design.
