Due to the intense need of bio-fuel in this energy crisis time a lab experiment was designed to have a cost effective ethanol production from potato and corn by using barely a source of diastase enzyme. The effects of temperature, yeast and barely quantity on ethanol production were also investigated. The results showed that potato yielded high amount of ethanol (242mL) as compared to corn which produced 64mL of ethanol. The cost estimate was also low in case of potato. It was also noted that with the increase of barely and yeast amount, ethanol production from different starch sources was increased. It was concluded from the present experiment that Pakistan has cheap sources of starch which could be used for biofuel production to withstand in this energy crisis time.
