It is predicted that in the future, production of diesel and gasoline could be replaced by algae biofuel. Interest in farming algae to produce biodiesel and other biofuels has developed in the energy sector. The good thing about algae farming (algaculture) is that it can be done with minimal freshwater; saline and wastewater can be used for algae production. It is recommended that algaculture should be done near heavy industries where it can help reduce carbon dioxide emission by feeding CO2 directly into the algae culture. Biofuel is produced from the breakdown of the algae cell structure. Algae can produce 60 times more oil per acre compared to land-based plants.
