That's commendable, and Colorado needs it. According to the last EPA measurement of regional power and the Union of Concerned Scientists, Colorado has the dirtiest power in the United States in terms of CO2 emissions, or at least it did in 2009. I researched those numbers for an article I wrote about electric car charging, and how the carbon footprint of those vehicles varies with respect to where one plugs in. By the numbers, a fully electric car driven in the Denver area is responsible for the same amount of greenhouse gas per mile as a car that achieves 33 mpg combined, approximately that of a Mazda 3. The article and links to some of the research are here: http://www.nytimes.com/2012/04/15/automobiles/how-green-are-electric-cars-depends-on-where-you-plug-in.html?pagewanted=1&_r=2&hp Paul > > > -- > PDML Pentax-Discuss Mail List > [email protected] > http://pdml.net/mailman/listinfo/pdml_pdml.net > to UNSUBSCRIBE from the PDML, please visit the link directly above and follow > the directions. -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
