In the past few years, high consumption of fossil fuels has led to a serious energy crisis due to increased demand of energy because of industrialization and modernization. It resulted in environmental concerns due to greenhouse gas emission with energy security issues. These fossil fuel resources have been getting threshold and exhaust as well as depletion. These issues have prompted the research to find out the alternative energy resources which are technically feasible, environmentally acceptable and economical competitive. Biofuels as an alternative to the petrodiesel are originated by inorganic ingredients instead of fossil fuels. Biodiesel production is abruptly growing worldwide due to its characteristic, such biodegradable, non-toxic, and sustainable energy. Biofuel production cost is a challenging part for its implementation that can be possibly overcome by utilization of waste feedstock as well as costly catalyst replace by available and waste material. The importance of energy systems and its role in economics and politics is not hidden for anyone.
