That's more than a $10,000 mark-up above the price of a base gasoline-powered model.
The most common of these are bioethanol and biodiesel that are blended with petroleum based gasoline and diesel fuels at varying percentages.
The cost of CO2 equivalent emissions avoided (CCA) was used as the metric to compare the environmental impact of each process as compared to conventional petroleum-based gasoline.
In this paper we propose a biorefinery optimization model that can be used to find the optimal processing route for the production of ethanol, butanol, succinic acid and blends of these chemicals with fossil fuel based gasoline.
To learn the potential effect of these oxygenates present in biofuels acting as drop-in additives on the petroleum-based gasoline fuel, a five components surrogate gasoline fuel (hexane, 2,3-dimethyl-2-butene, cyclohexane, isooctane, and toluene) was then proposed and validated by comparing its laminar flame speed with commercial gasoline.
No fuel is "greener" in the proper sense of using fewer overall resources than petroleum based gasoline.
- In order to reduce consumption of petroleum based gasoline the new energy bill calls for the enhanced production and use of corn ethanol.
A fossil fuel, yes, but as a transportation fuel emitting some 25% less greenhouse gases than petroleum based gasoline, and now being domestically sourced and cheaper by far.
The Energy Information Agency expects a reduction of 6.9% in petroleum based gasoline consumption this year from the 371.2 million gallons/day consumed in 2007.
- Given the need to reduce the consumption of fossil fuels, given our lack of self discipline, would you be prepared to use the bully pulpit of the presidency to pass a national cap on fossil fuel based gasoline so that in five years say, the consumption of petroleum based gasoline will have been reduced by 50% from todays levels.
