Due to increase pollution in the atmosphere and rapid increase in global warming, it becomes necessary to consider on develop and encourage renewable and environment-friendly technologies to produce energy. Based on research, biotechnology firm's focus on algae that is promising. Organic Dry Algae Biomass is far more productive than terrestrial fuel crops. Production of energy is fairly non-polluting and considered clean through biomass. Depending on the species, up to half algae mass is made up of lipids - natural oils which can be extracted and used as straight algal 'crude', or refined to higher-grade hydrocarbon products ranging from biodiesel to bio-jet fuel for aircraft. And, they also can be fermented to make bioethanol and biobutanol.
