U-M researchers challenge USPS EV environmental study

Green Car Congress

In its analysis of the potential environmental impacts of the Next Generation Delivery Vehicle program, the Postal Service underestimated the expected greenhouse gas emissions from gasoline-powered vehicles and overestimated the emissions tied to battery-electric vehicles, according to U-M researchers. The work was supported by Ford Motor Co.

Maxwell supplying ultracaps to ABB for hybrid version of Philadelphia rail energy recuperation system

Green Car Congress

Rather than having the braking energy be dissipated, the ENVILINE Energy Recuperation System (ERS) saves the surplus braking energy of the train by returning it back to the AC grid. When used with batteries, ESS can also provide emergency power and generate revenues by participating in the local energy markets.

CMU study finds controlled EV charging can reduce generation cost, but at greater health and environmental costs depending upon the generation mix

Green Car Congress

Although electric vehicles have lower tailpipe emissions than gasoline powered vehicles, the changes in emissions associated with vehicle electrification on a life cycle basis will depend on the emissions associated with the operations of the power plants used to charge the battery.
