Article 25 of the Universal Declaration of Human Rights:
Everyone has the right to a standard of living adequate for the health and well-being of himself and of his family, including food, clothing, housing and medical care and necessary social services, and the right to security in the event of unemployment, sickness, disability, widowhood, old age or other lack of livelihood in circumstances beyond his control.
That basicly gurantees right to energy and would cover all examples given above. Housing without proper heating, in an enviroment were it is needed is no longer housing. Spoiled food is not longer food and medical service do include having energy for medical devices.
