This document discusses the concept of a "prosumer energy culture" and a fractal-like grid. It notes that households are increasingly producing their own energy through technologies like solar panels. This is shifting energy profiles and creating constraints on the traditional grid. A fractal grid that recognizes consumer values like independence, control and sustainability could help alleviate these issues through approaches like localized peer-to-peer energy sharing and collective prosumerism. It would incentivize distributed energy investment, increase resilience and allow greater utilization of renewable resources.
