The promotion of energy from renewable sources is a key objective of the European Union's energy policy, as outlined in Directive (EU) 2018/2001, known as the Renewable Energy Directive II. This directive introduces the concept of Renewable Energy Communities (RECs), which are groups of citizens and/or small and medium-sized enterprises that produce and share electricity generated from renewable sources. Additionally, its amendment, Directive (EU) 2023/2413, sets a further goal of achieving an annual sustainable biomethane production of 35 billion cubic meters by 2030. Within this context, Northern Italy emerges as one of the European regions with the highest potential for biogas production.
