Alternative Fuel of Vehicle- Biodiesel

Alternative fuels are derived from resources other than petroleum. Some can be derived from renewable sources. Often, they are more environmental friendly. Concerning of high oil prices and the potential for peak oil, finding a cleaner alternative fuels and advanced power systems have became a top priority for all of the world. It will reduce our dependence on mineral oil.

Biodiesel refers to a vegetable oil or animal fat-based diesel fuel. The process itself is said can actually be done at home. True or not, but the biodiesel can be made by cooking oil, that is no kidding. Not only is it much cheaper and cleaner than fossil fuel, it also make your car smell like french fries.  🙂


Global warming is becoming pervasive all over the world. The greenhouse gases in the earth’s atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone, which is primarily caused by the auto-tail emission. These greenhouse gases trap radiation from the sun, and put the heat back to the surface of the planet again, causing greenhouse effect, while the diesel car can always produce a cleaner emissions.

The biodiesel is made of renewable resource– plants, which can be grow and replanted again and again. For example, the rapeseed and switchgrass process a higher oil content. Besides, the rise in demand for more food-biofuel crops can create more job opportunities for the rural people and  reduce poverty to the poor country.


Another outstanding advantage of the biodiesel is its well energy efficient performance. Vehicles that run on biodiesel get 30 percent better fuel economy than gasoline-powered vehicles. According to U.S Department of Agriculture, “every unit of fossil fuel energy needed to grow and refine soybeans into biodiesel, four and a half units of energy are gained. However, for every unit of fossil fuel needed to produce petroleum diesel, the return is less than one.”

By the way, the biodiesel can also run in existing diesel engines with little or even no modification to the engine or its fuel system. Next time when you top up your tank, you can think about where the gasoline is coming from, and take a more responsible choice of what you need.
