%0 Journal Article %T Blockchain and Energy Transition: What Are the Challenges for Cities? %A Abdelkader Derbali %A Lamia Jamel %J International Journal of Global Energy Markets and Finance %D 2019 %R 10.12691/ijgefm-2-1-2 %X The aim of this exploratory note is to draw the first outlines of the experimental use of blockchains for energy at the local level: to what extent can blockchains impact the energy transition of cities? How can cities and their inhabitants, thanks to this technology, become a producer of energy and consume all or part of this same energy? This exploratory note provides an overview of the types of energy this technology could apply to, as well as potential uses in the territories. Multiple experiments seem to be already launched by public and private actors, for example in the sector of municipal buildings, exchanges between private actors or in the energy sector for the (electric) mobility of people. The opportunities and vigilance of blockchain technologies for communities are discussed. In addition, perspectives to establish if and when a massification of this technology at the local level could be possible are presented %U http://www.sciepub.com/IJGEFM/abstract/10989
