Report Suggests Plug-in Hybrids Threaten to Strain Freshwater Resources
July 9, 2008 10:47 am | by Jason Lomberg, Technical Editor | Blogs | CommentsAdvanced technology vehicles are the wave of the future, but they aren’t the elegant solutions advocates posit them as. The conservation of one resource inevitably comes at the expense of another resource. A report by Carey W. King and Michael E. Webber of the University of Texas suggests that plug-in hybrid electric vehicles (PHEVs) will place a strain on the nation’s freshwater resources. The research compares miles driven with a conventional internal combustion engine vs. a PHEV.
