The objective of this study is to analyze the international legal rules affecting renewable alternative energy resources of the future - things like wave, current and tidal energy, OTEC, coastal wind power, offshore geothermal, polar energy resources, space-based solar collection, and mining of celestial bodies for power sources like helium-3. Its prime focus is on the principles of domestic law of those nation-states fortunate enough to be blessed (or cursed) with either the availability of, or the capacity to harness, any of the foregoing or other energy related resources.
