Energy communities as accelerators of energy transition in cities

The European Green Deal states that greenhouse gas (GHG) emissions should be reduced by at least 50% by 2030, and that there should be no net GHG emissions by 2050. The energy sector is a key in this transformation, and energy communities can as accelerators of transitionsKey findings:•Future scenarios outline a decentralized energy system in which smaller generation units have become more economically viable and turned economies ‘upside down’. •This will be an energy system with increased penetration of information technologies, allowing for more flexible and less hierarchical management of infrastructure. •This future system will also entail, for example, the increased electrification of transportation infrastructure and the increased use of heat pumps in energy-efficient buildings
