The plants take the energy from the sun and save it into the oil.

This energy can be used as fuel on engines, to move cars or to generate electricity and many other uses.

The biofuel can be used to move the world as petroleum substitute.

Biofuel production from vegetable oil is not a secret, but have some material cost. Making biodiesel is profitable as soon the petroleum prices reach around $75 a barrel.

With current oil prices around $77, there is more interest in renewable gasoline alternatives. Electric cars and hydrogen fuel cells on this days are being proposed as energy as alternatives to oil, but it will take be several years of development to make it massive.

Biofuels are renewable and avalaible right now.

The main concept is that fuels can be made from natural and renewable sources instead of fossil fuels. People knows how to produce vegetable oils from a wide range of familiar crops such as corn, soybean, palm, rapeseed, canola, cottonseed, sunflower, peanut and even animal fat. And all this sources can be used to produce different kinds of Vegetable Oils.

In the industry, the plant oil is the largest source of vegeoil, but it can even be made from recycled cooking greases from the kitchen or a restaurant ! For example you have vegetable oils in common things like butter.

Biofuels can be made virtually from materials that contains fat on any form. Oils and fats the same thing. Oils are simply fats that are liquid at room temperature.

Biodiesel is not pure vegetable oil. The biodiesel is made by a chemical reaction with alcohol and the vegetable oils. The final biodiesel product, can be used in any diesel engine without modifications or can be used in pure form or blended with petro diesel at any level.

Biodiesel can be used in compression-ignition (diesel) engines with little or no modifications. Biodiesel can be blended at any level with petroleum diesel to create a biodiesel blend. Mixes of 20% bio- with 80% petroleum diesel will significantly reduce carcinogenic emissions and gases that may contribute to global warming.

Raw or Straight Vegetable Oil (SVO) also can be used to fuel diesel engines, but it is recomendable to make some some convertions before. The Vegeoil have glycerin that can be converted into soap inside, and that is not good for your engine at long term.

The only problem found in some older diesel vehicles are the rubber components in the fuel system, because will be break faster with biodiesel usage and have to be replaced more frecuently or use another material.

The industry use a process called transesterification, to purify the oil with some alcohol like methanol (CH3OH) or ethanol (CH3CH2OH) with the presence of a catalyst such as potassium hydroxide (KOH) or sodium hydroxide (NaOH). The triacylglycerol is transformed to esters and glycerol.
