Abstract Renewable Energy Communities (RECs) are anticipated as key means to restructure the energy system in European Union. However, there still many open questions regarding needed conditions that would allow their extensive roll-out. Here we propose a techno-economic model assess by RECs operate an economic beneficial way Belgian context. The results indicate while user type, consumption an...

Local governments across the United States spent approximately $5 billion, an average of $100 million per state, on energy for their public schools in 1992. This represents a tremendous drain on education dollars of which part (captured through building system and operational efficiency improvements) could be directed toward more important educational needs. States and local governments know th...
