Argonne LCA study finds many alternative fuels consume more water than petroleum and natural gas fuels

Green Car Congress

Researchers at Argonne National Laboratory have analyzed the water consumption for transportation fuels in the United States using an extended lifecycle system boundary that includes the water embedded in intermediate processing steps. Their findings included: Fossil fuel pathways generally have the least impact on water resources.

Navigant forecasts global road transportation energy consumption to increase 25% by 2035; 84% from conventional fuels

Green Car Congress

Navigant also projects that investments in alternative fuel and fuel efficiency improvements will reduce annual energy consumption in the United States year-over-year. Conventional fuels (e.g., gasoline and diesel) represent the bulk of energy consumption throughout the forecast period. Click to enlarge.
