The implementation of the EU’s Green Deal as a ‘trump card’ for the State legislator towards regional regulatory autonomy?

Abstract [En]: The essay examines the impact of the EU’s Energy Transition on the autonomy of Italian Regions with regard to the installation and expansion of plants powered by renewable energy sources, also in light of the most recent developments in the regulatory and jurisprudential framework. In the end, it outlines also some measures that, from a de iure condendo perspective, could promote a greater sharing of strategic energy policy decisions between the national legislator and local communities.
