It is shown that the energy requirements for interstellar colonization exceed that for intraplanetary colonization by a factor of ten million or perhaps much more. This is offered as an argument against extensive interstellar colonization as a means of dealing with population expansion, and as a possible explanation of the Fermi paradox.
