Electricity Power Generation Community Networks

According to Self-sufficiency - at what price?, I would think that it is just a matter of time for improvements in the technology and build more awareness (maybe a campaign like the Centrino program in WiFi by a solar panel manufacturer or the government itself?) in order to generate volumes that will drive prices down and make community electricity power generation a possibility. We might soon hear of municipal renewable power generations in the not too distant future. Thinking of it there are many parallels between broadband and clean energy. Both are improvements in current utilities that we need and both have incumbents that are hell bent to defend their current position by killing innovation by lobbying for legislations that prevent smaller players to compete.
