Abstract

With the rapidly growing world population and rising consumption of energy, human being are pushed into a dangerous situation and face some serious problems. Based on known oil reserves and the worldwide consumption rate, most estimates suggest this reserve has only 50 more years of production left in it. In other words, the traditional energy may be used up before 2060 if human being do not take any actions. Another big problem is about environment. Greenhouse gas emission from burning fossil fuels has drawn worldwide attention. In order to settle these problems, scientist makes an effort to develop some renewable energy technologies, such as bio-fuel, wind, water and solar energy. Biofuel has numerous advantages compared with traditional fossil fuels. However, what if biofuel compared with other renewable energy? Is biofuel the best choice to alleviate energy crisis. We will only focus on the third generation of biofuels - Algae fuel.
