The use of biodiesel is being campaign by the government which is expected with this solution is the use of diesel fuel can be reduced because of the mix with diesel, which is the result of the oil palm oil, corn, soybeans, space, sugar cane, cassava, etc..
Human generations has been farming for their daily meals. Even today we still see a lack of food from some country. We still can not self-sufficient in food. With the growth of both sides of the human population and the car, if we will use some food items that need to be energy, whether we want to feed people or cars?
There will be no land, water or soil productive enough to be able to replace all our energy needs. Production of biodiesel itself also uses a lot of land and energy. Production of land plants such as palm oil or distance will require fertilizer made from natural gas results, the pesticide is also derived from oil, the input of energy such as fuel for tractors, trucks, and distillation plant. In addition, the land will also need to reduce water and soil fertility power.
When we see the energy used, the biodiesel will use more energy in the production stage compared with ordinary oil, from exploration wells to be used in the car.
With the competition between the need for human food and energy, so the supply is running low demand and high commodity prices will increase so that by the end of the chain then the final product sold to customers would be more expensive. For example, when palm oil prices rise, because oil palm is the basic ingredient for the manufacture of ice cream, biscuits, butter, cooking oil to soap and shampoo, it is conceivable consequences of CPO prices rose to around inflation and our economy.
Employers also with the price increase would be their incentive to plant more. And if our heterogeneous forest full of useful plants and animals that depend on these ecosystems, would be destroyed by the homogeneous forest of large plantations. Finally is the destruction of plant and animal species that important to our natural balance.
The best solution remains to find the best solution alternative renewable energy from water / wave, wind and sunlight.
