We present an interactive demo that illustrates the performance of our multi-agent-based system for trading {\textquoteright}green{\textquoteright} energy. The system implements the NRG-X-Change concept and uses real-life data for energy consumption. NRGX-Change encourages prosumers to locally trade their excess of energy while payments are carried out using NRGcoins, which is a novel decentralized digital currency. We illustrate the performance of a real and typical neighbourhood in Belgium with 62 residential houses, 56 of them are consumers while the remaining 6 are prosumers. Participants can interact with the demo by playing with energy consumption and production, and analyzing in real-time the behaviour of the energy market and in turn the price for NRGcoins.
