Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane.[1][2] When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
