【正文】 t? This question has been asked many times. In fact, many people are concerned about the contribution of biomass in the global warming because the bustion of biomass will produce carbon into the air. However, this point of view could be wrong if you understand the biomass cycle. Although biomass can be found anywhere in the world, some places like desert areas in the middle east such as Saudi Arabia, possibly will face difficulties to get enough plant and trees to be used as a biomass source. As a result, the transportation of the plant and tress to theses areas will be costly and using biomass in this case will be worthless. Figure 2: Carbon cycle. Conclusions: To sum up, this essay has shown that using biomass in industry and specifically in power plants to produce electrical power, would help many people to find jobs and could help the governments to diminish the unemployment rates. Moreover, every year, countries spend billions of dollars to sell oil or gas for generating electricity, for this reason, it will be more economical and useful if biomass has been used. In the Fahad Rafai 8 electricity markets it can be said: energy is money. And by using biomass this saying can be verified. Moreover, biomass can be used in different methods which mean more flexibility. Although the power plants which use biomass will produce less power than that power plant which uses fossil fuel, still using small biomass units in the villages and small towns would be more economical than using normal fossil units.
