The use of biodiesel as a fuel source has many benefits. Firstly, biodiesel is cleaning diesel engines from deposits accumulated over time. Secondly, biodiesel can be cheaper than traditional diesel fuel because raw materials such as used vegetable oil can be quickly and cheaply available in places like restaurants. However, the time and energy spent on creating biodiesel can make it more expensive than the available diesel fuel. Third, biodiesel is a clean, renewable source of combustion energy. Fourth, low-volume biodiesel production does not require more power than output. According to Biodiesel.Org, the leading organization in research and marketing of biodiesel.

Biodiesel has one of the most substantial "energy balances" among all liquid fuels. We get 4.5 units of energy for each group of fossil energy needed for the production of biodiesel. This takes into account sowing, harvesting, fuel production and fuel transportation for the end-user.
