Your vehicle is probably running on ethanol-enhanced gasoline as this is currently the cheapest fuel you will find at the gas station. Ethanol has been touted as the answer to reducing Americas dependence on foreign oil supplies as well as reduction in greenhouse gas emission levels. People are beginning to question this proposition as producing swathes of crops is possibly as inefficient as the fuel it produces. Ethanol is a fuel that cars have been using to run without optimization for a long time, so obviously its not the right choice. A new contender for better fuel economy is using hydrogen gas in cars.

It is most likely that your car is using an ethanol-gasoline fuel blend. Ethanol, produced from corn as fuel, has been hailed as a breakthrough to reducing both American’s reliance on foreign oil and dangerous greenhouse gas emissions. This is a moot point as many people claim that growing tonnes of crops to produce a fuel that is no better than gasoline is a cul-de-sac solution. For instance, Ethanol has been used by cars to run without optimization for quite a while without significant changes in fuel prices or greenhouse emissions. A newer contender is hydrogen gas in cars for improved fuel economy.

As gas prices continue to rise to unprecedented levels, every available resource is being investigated to replace fossil fuels by august official bodies like the energy commission to the average Joe and Josephine in the street. Hydrogen fuel cells seem to be a possible alternative. Hydrogen for cars will not only provide the chance to explore new energy sources; it will also open up better potential for us to improve how we travel overall.
