Argonne and NGO Energy Vision case studies demonstrate success of renewable natural gas as transport fuel

Green Car Congress

One study looks at Fair Oaks Farms, a large dairy cooperative in Indiana with roughly 36,000 cows. Renewable natural gas production for transportation totaled 151 million gasoline gallon equivalents in 2017, up from 125M GGEs in 2016 and 90M GGEs in 2015. Energy Vision and Argonne produced the studies jointly.

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

Stacked bars show the change in generation cost combined with the median damages by pollutant assuming the 2010 social cost of carbon given by the Office of Management and Budget ($31 in $2010). However, this shift results in increased externality costs of health and environmental damages from increased air pollution.
