The EU's Renewable Energy Directive requires countries to track where renewable electricity comes from using Guarantees of Origin (GOs). However, the current system isn't working well, leading to too many GOs and some shady practices.

The author suggests changes to make the system more effective and reliable, helping to boost funding for new renewable projects and ensuring consumers get truly green electricity.
