No! It's a totally essential concept! I think the Hummer versus Prius example was probably contrived and skewed, but the concept of energy cost accounting is something we don't do enough of these days. For example, some energy cost analysis indicates that some shale oil costs as much as $120/barrel to produce, although the market rate is only $100/barrel. Some studies even suggest that some shale oil well use more energy than they will ever produce. For more info, look into "emergy," a concept rigorously developed by Howard (HT) Odum. :::: The more the work is left to nature, the greater the net yield but the longer the time required... Thus sometimes the most apparently productive and high-yielding sources of energy involve a lot of activity for little return, while long-term investments, especially in naturally grown forests, provide the greatest value for future generations. -- David Holmgren :::: Jan Steinman, EcoReality Co-op :::: _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org For EV drag racing discussion, please use NEDRA (http://groups.yahoo.com/group/NEDRA)
