Microalgae: Future biofuel

Abstract

Uses of non renewable sources like petroleum increase the production of green house gases and global warming. To overcome these problems use of renewable sources is necessary. Microalgae are a renewable source of energy. We can produce biofuels like lipid, methane, bioethanol and hydrogen from them; they are more efficient than conventional plants and can be cultivated using simple methods. Main focus of this review article is to point out the role of microalgae in the production of biofuels, their biosynthesis and comparison of algal biofuel with other sources.
