Chu: Carbon Dioxide Is The Horse Manure Of Today

Presenting the inaugural Department of Energy Quadrennial Technology Review, Secretary of Energy Steven Chu discussed the priority of ending the national reliance on gasoline-powered automobiles. Chu reviewed the history of automotive technology, including the rise in American dominance in automobile manufacturing. “The rise of automobiles was driven by environmental pollution,” Chu said, explaining that horse manure had become a major problem in urban streets like New York City. “Carbon dioxide now is like horse manure then” — except, Chu noted, that carbon dioxide doesn’t have the same kind of odor problem that manure does.
