 The modern-day desire for community was notably characterized by the communal "back to the land" movement of the 1960s and 1970s through communities such as the earliest example that still survives, the Miccosukee Land Co-op co-founded in May 1973 by James Clement van Pelt in Tallahassee, Florida.In the same decades, the imperative for alternatives to radically inefficient energy-use patterns, in particular automobile-enabled suburban sprawl, was brought into focus by recurrent energy crises.The term "eco-village" was introduced by Georgia Tech Professor George Ramsey in a 1978 address, "Passive Energy Applications for the Built Environment", to the First World Energy Conference of the Association of Energy Engineers, to describe small-scale, car-free, close-in developments, including suburban infill, arguing that "the great energy waste in the United States is not in its technology; it is in its lifestyle and concept of living."
