The international dependence on non-renewable power supply including fossil fuels has led the sector toward power insecurity. This has necessitated the worldwide attempt to reduce the dependence on  fossil fuels and broaden an economically feasible and scalable alternative  fuel supply so that it will  additionally lessen huge emissions of CO2 within side the  surroundings which in flip will result in  discount environmental pollution. Biofuels have the  potentials to offer a feasible opportunity to fossil  fuels and can lessen overall CO2 emissions.  Algae appear like a rising supply of biomass for biodiesel  that has the capacity to absolutely  displace fossil fuel. Biodiesel has gain sufficient interest in latest years  because of its green  nature, non-poisonous characteristics, biodegradability and decrease net  carbon cycle as  compared to standard diesel fuel. In this research, Spirogyra sp. was collected from Tubu  river, a tributary of River Kaduna, as a source of biomass feedstock for biodiesel production.  Spirogyra  sp. turned into cultured in various nitrogen (2.94 x 103 (100%), 2.20 x 103 (75%),  1.47 x 103 (50%), 0.73 x  104 (25%), and 0.000 (0%)) concentrations in Bold’s Basal Media (BBM) in a laboratory test for 21 days at  25-28°C ambient temperature. Oil from Spirogyra  sp. become extracted in soxhlet extractor using  n-hexane as solvent and transformed into  biodiesel through transesterification reaction. The highest biomass growth, oil, lipid content and biodiesel production were observed in treatment with 75% (2.20 x 103) Spirogyra sp. has a big capability for biodiesel production.
