Biodiesel energy is the energy obtained from natural biodiesel. Biodiesel is a fuel that can be made from waste vegetable oil. The waste vegetable oil is considered to be the best source of biodiesel although other sources can be used to manufacture bio diesel.
The other sources that can be used to make bio diesel are virgin oil feedstock, rapeseed oil, soya bean oil, oil from crops like mustard, palm and hemp. Algae are another source from which biodiesel can be derived. It can also be produced from animal fats like tallow, lard and yellow grease. Bio diesel can also be manufactured from non edible oils like Jatropha, neem oil and castor oil.
The biodiesel so produced can be used in the form of energy called biodiesel energy. The use of biodiesel energy can be made in place of fossil fuels. This means that biodiesel energy can be used as an alternative to fossil fuels that are decreasing in quantity all around the world. Fossil fuel reserves are depleting because the energy demands are increasing and they are at present the only sources on which there is maximum pressure to meet the energy requirements. Also fossil fuels cause a lot of pollution when they are burnt. Biodiesel energy on the other hand is a renewable source of energy that will never finish and will always be readily available for use. The use of biodiesel energy is also healthy for the environment.
