Bio Fuel Cars For A Revolutionary Change

For long the huge petroleum deposits have always rendered diesel and gasoline cheap while making biofuels forgotten, however with the increasing oil prices in the recent times together with growing concerns of the effects of carbon emissions on global warming, biofuels have been enjoying an increasing popularity. This has seen the rise of biofuel cars to bring a revolutionary change.

fuel1What are biofuels?

1. The biofuels are derivates of plants such as corn, sugarcane, wheat, sorghum, rapeseed, and beet. The biofuels that the new revolutionary cars use are found in forms of ethanol or biodiesel.

2. In Brazil half of the country’s sugarcane crop is used as biofuel while in North America, ethanol refiners’ use around 40 percent of the country’s corn crop.

3. In Europe the biodiesel industry uses 60 percent of rapeseed crop produced in the entire continent; this is majorly used to power biofuel cars which are increasingly becoming popular.

What are biofuel cars?

1. Biofuel cars are models which are designed where the engine uses biodiesel to run. Some engines have been designed to run 100% on biodiesel while others have to run on 50% blend of biodiesel. Some conventional engines can also be converted to accommodate or run on biofuels although it has been found to be very expensive.

2. Several carmakers have made cars which are compatible to use biodiesel either fully or as blend, however, not all have made an official approval of the same.

3. Companies that have cars that can run on biodiesel include; Chevrolet, Audi, DaimlerChrysler, Ford, BMW, Land Rover, General Motors, Mazda, Isuzu, Mercedes, Nissan, Toyota, Mitsubishi, Peugeot, Volvo, Volkswagen and Saab. These companies have approved all their cars produced between 1996 and 2004 to run on 100% biodiesel.

4. Companies with cars that can use ethanol are DaimlerChrysler, General Motors, Nissan, Isuzu, Mercedes, Mazda and Mercury.

Reasons and direction of the revolution

• Cars have been blamed for being the major source of atmospheric carbon dioxide, which has been blamed for being the main cause of global warming. The argument for the use of biofuels has been that since plants absorb carbon dioxide as they synthesis, crops grown for biofuel production will absorb all the carbon dioxide emitted by the cars as they burn these fuels. The revolution has also favoured the use of biofuels on grounds that unlike oil reserves, biofuels are renewable since more crops can be grown to produce the fuels.

• The expansion of the biofuel revolution gets support from government targets and subsidies that seek to trim down use of fossil fuels, cut on oil import and ultimately meet carbon diminution goals.

• There have been plans to use grasses and saplings to produce biofuels in the future. This is because these both contain more cellulose compared to crops currently being used for biofuels production. If it will be possible to turn the cellulose to biofuels, it will be more efficient than the current ones and it will emit less carbon dioxide.
