Conclusion

Energy analysis offers a means of judging the appropriateness of a system, or its optimal form. This cannot be done without strict concern for the conventions, taking the analysis back to the same system boundary as money. The use of energy as a numeraire undoubtedly means loss of some information, so that for an immediate decision affecting a matter of short duration, money remains the best criterion. However, as the decision period stretches into the future, energy can provide a useful and stable alternative criterion.
