Study Finds Water Use for Switchgrass Ethanol Production Approximately the Same as for Gasoline

Green Car Congress

Consumptive freshwater use for ethanol and petroleum gasoline production. The production of both bio and petroleum feedstocks and fuels requires substantial water input. In many cases, the Argonne team noted, crude oil production is increasingly water dependent. Data: Wu, ANL/ESD/09-1. Click to enlarge. Data: Wu, ANL/ESD/09-1.

Researchers describe the “where” and “when” of life cycle emissions from gasoline and ethanol in the US

Green Car Congress

Contributions of regions to total life cycle emissions for three fuels (µg per vehicle-mile traveled per km 2 land area). On-road transportation accounts for approximately 20% of United States energy consumption. Upstream processes involved in fuel production also contribute to overall environmental impacts.

IHS CERA meta-analysis finds lifecycle GHG emissions for fuel produced solely from oil sands crude average 11% higher than from average crude refined in the US; high variability

Green Car Congress

Average values for WTW GHG emissions for oil sands and other crudes, tight boundary. When the oil sands products refined in the United States are considered—a mixture of oil sands and lower-carbon blending components—the GHG emissions are, on average, 9% higher than the average crude processed in the US.
