The NY Times has an interesting article on a network of home solar installations which trade their power with their neighbors. Solar Experiment Lets Neighbors Trade Energy Among Themselves "The project is still in its early stages — it has just 50 participants thus far — but its implications could be far reaching. The idea is to create a kind of virtual, peer-to-peer energy trading system built on blockchain, the database technology that underlies cryptocurrencies like Bitcoin. The ability to complete secure transactions and create a business based on energy sharing would allow participants to bypass the electric company energy supply and ultimately build a microgrid with energy generation and storage components that could function on their own, even during broad power failures." "Across the globe, upstart companies like LO3 Energy, which is designing the Brooklyn experiment with the industrial giant Siemens, are building digital networks that offer the promise of user-driven, decentralized energy systems that can work in tandem with the traditional large-scale grid or, especially in emerging economies, avoid the need for a grid at all." Interesting model to deal with utility abuses.
