A team of biologists and engineers modified Rhodopseudomonas palustris TIE-1 (TIE-1) so that it can produce a biofuel using only three renewable and naturally abundant source ingredients: carbon dioxide, solar panel-generated electricity and light. The results are reported in an open-access paper in the journal Communications Biology.
The US Department of Energy (DOE) released findings from a new project—Transportation Energy Futures (TEF)—that concludes the United States has the potential to eliminate petroleum use and greenhouse gas (GHG) emissions by more than 80% in the transportation sector by 2050. Using less fuel in vehicles. Click to enlarge.
AT&T plans to invest up to $565 million as part of a long-term strategy to deploy more than 15,000 alternative-fuel vehicles over the next 10 years. estimates that the new vehicles will save 49 million gallons of gasoline and reduce carbon emissions by 211,000 metric tons over the 10-year deployment period.
Additionally, neither mechanism would compromise the greenhouse gas reduction goals set by Assembly Bill 32. The LCFS program calls for a 10% reduction in the carbon intensity of fuel sold in California over the next decade. Obligated parties are upstream producers and importers of gasoline and diesel fuel sold in the state.
Policies to entice consumers away from fossil-fuel powered vehicles and normalize low carbon, alternative-fuelalternatives, such as electric vehicles, are vital if the world is to significantly reduce transport sector carbon pure-emissions, according to a new study. Share of EDVs in 2050. McCollum et al.
Which are the alternativefuels for cars that could replace gasoline in vehicle? Are you aware of the most commonly used fuel in automobiles? The answer is petroleum fuels. The fossil fuels are highly significant in the global economy. Do we have enough fuels for the future use?
The contract also calls for evaluating vehicles to ensure compliance with current emissions and other regulatory requirements and safety testing powertrains, batteries, and emission control systems.
While vehicle efficiency will be the most important and most cost-efficient way to reduce transport-emissions, biofuels will still be needed to provide low-carbon fuelalternatives for planes, marine vessels and other heavy transport modes, and will eventually provide one fifth (2.1 Source: IEA.

Argonne’s GREET model (Greenhouse gas Regulated Emissions and Energy Use in Transportation) is, for example, an inventory tool. Life cycle impact assessment (LCIA) involves weighing trade-offs between multiple and incommensurate criteria. Central weights box and whisker plots. Rogers and Seager (2009) Click to enlarge.
