As people know, with the development of economy and technology, the demand for traditional sources of energy especially some fossil fuels such as coal, oil and natural gas became more heavily all over the world. There are many problems created by the overuse of fossil fuels like global warming and all kinds of pollution. If this situation do not change, then our future generations will suffer from unprecedented disaster. Nowadays some of alternative sources of energy have being utilized widely for different domestic and industrial applications in many countries, such as solar energy, wind energy and so on. This essay will focus on how to harness biogas effectively and it will highlight biogas as an important alternative energy plays an important role in saving natural resources and protecting environment. Biogas, one of alternative sources, can be produced from raw materials such as human, animal and plant waste. In order to harness biogas effectively, it is important to use advanced technology to improve the efficiency of using biogas. For example, two American utilities have found advanced purification technology of biogas that turn organic waste from farms and gas from water treatment plants into biogas and feed into state’s natural-gas pipelines, which can serve to local residence. (Rosenthal, E.2010) Purification technology not only produce more efficient biogas but also is effective in recycling waste and reducing the negative effect on environment. The other method to exploit biogas effectively is to get government’s support on establishing an effective mechanism that encourages people use biogas as a fuel for cars. For example, the authorities in Kristianstad, a city in Sweden, want to use biogas as a fuel for transportation system and they hope to build a city with no emissions at all in the future. (Rosenthal, E.2010). In order to promote biogas
