Biodiesel: An eco-friendly alternate fuel for the future: A review

In today's society, researchers around the world are searching for ways to develop alternate forms of fuel. With the ever-rising fuel costs, developing alternate energy is a top priority. Biodiesel was developed to combat the high gas and oil prices. It is especially made for use in diesel cars and trucks. Biodiesel can be made from all natural foods that can produce oil. Oils such as vegetable, canola, peanut, rapeseed, palm, and olive oil can be used as bio diesel fuel. Virtually all oils that are used in the kitchens everyday can fuel automobiles. Biodiesel fuel is better for the environment because it burns cleaner and does not pollute the atmosphere. It is non-toxic and biodegradable, making it the perfect fuel. Many car manufacturers are realizing that the bio diesel automobile is becoming more popular, and are jumping on the bandwagon, by developing their own version of a biodiesel vehicle. They realize that the need for these vehicles will increase, and predict that they will be ready for the onslaught. Diesel engines have superior fuel efficiencies, and hence they are predominantly used in commercial transportation and agricultural machinery. Due to the shortage of diesel fuel and its increasing costs, a need for an alternate source of fuel for diesel engines is imminent. This paper investigates the suitability of biodiesels as such an alternative with particular reference to automobiles. It reviews techniques used to produce biodiesel and provides a comprehensive analysis of the benefits of using biodiesel over other fuels
