This text proposes to add the notion of access to energy autonomy to Article 25 of the Declaration of Human Rights. This is so that access to energy no longer depends exclusively (or almost) on multinationals, some of which have become richer than many countries! This text should be addressed to political, institutional and non-political decision-makers [...]
