EVs and the Environment: The Discussion Continues

Questions about how to evaluate the greenness of electric vehicle technology provoke heated debate


Our July 2013 cover story, “Unclean at Any Speed” by Ozzie Zehner, generated an enormous amount of feedback. Since it’s clearly a topic people want to talk about, we’ve created this special online section, where you’ll find various responses to the article, as well as some additional commentary and resources on alternative transportation technology research.

Note that IEEE does not typically take official positions on technology topics, and that articles appearing in IEEE Spectrum represent the ideas of its authors, not IEEE or its organizational units. Spectrum’s editorial mission is to act as a forum for the discussion of new and emerging technologies, and we hope you’ll add your own thoughts to the deliberations unfolding here.
