When a whole country runs on one grid and one global oil market, every war and every price spike lands on every household at once.
The Law of the Earth sends energy back home. Anyone may install renewable, non-disruptive energy devices on or near their own home. Villages may build energy infrastructure for their own use, and every village shall aim to be energy self-sufficient. Existing long-distance grids may be maintained, but not expanded. (Title 3: Ecology.)
Fossil fuels have one lawful purpose: to power civilization temporarily, until clean, renewable energy matures. They are not for economic growth. Existing energy networks may continue, to keep society stable, during the transition. New nuclear reactors and the mining of nuclear fuel are unlawful, and fracking is forbidden everywhere.
And under the Seniority Principle, older and more basic systems must never depend on newer ones, so that a village can still cook, eat, and stay warm when the grid goes down.
