The human population is expected to rise by 50% or more by 2030, which is going to lead to a huge rise in energy consumption. The consumption rate of natural fossil fuels is estimated to be 105 times higher than what nature can provide. In addition, utilization of fossil fuels causes a lot of problems by producing greenhouse gases that lead to increase in global warming. Therefore, finding an alternative energy with less carbon prints has become one of the most challenging tasks with a lot of research impetus. In this context, biofuels or fuels derived from living creatures is a good option with their renewable nature along with the reduced CO2 emission. Many current biofuel options are based on the usage of produce of traditional farming which can be used as food also. In addition, there is a land usage competition regarding the use for fuel crops or food crops. After a long time, researchers proposed a solution with microalgal biofuels where microalgae convert CO2 and water in the presence of sunlight into valuable biomass for biofuels. The purpose of this study is to condense recent research on the potential of microalgal species for biofuel production and to explore prospective implementation strategies. In addition, some specific microalgal species and their benefits for biofuels are emphasized in this paper. The latest initiatives and successes in increasing production of micro-algal biofuels using different techniques are also discussed. Other applications that can be combined with biofuel generation, such as wastewater treatment and CO2 reduction, are presented. The benefits and drawbacks of algae for the biofuel sector are also discussed.
