The transition of the global energy sector towards renewable energy sources and energy efficiency, replacing fossil-based energy production and consumption systems (oil, gas and coal) is more essential than ever. The four main pillars towards this energy transition, also known as 4 Ds, will be presented as follows: Decarbonization, Decentralization, Digitization and Democratization. These dimensions are combined to change the nature of the way energy is produced, purchased and sold. In this context, consumer-centric big data application services and applications are being developed and will be discussed, based on the large amount of information available and the combination of the evolution of artificial intelligence and “big” data management technologies. Emphasis will be given to the intelligent energy services that can enable consumers to adopt energy-efficient practices, their transition to prosumers and the promotion of energy autonomy concepts, through the creation of resilient and energy-efficient communities, bringing multiple benefits to households and industry sector.
