of biofuels. The emission of greenhouse gases especially the carbon dioxide is thought to be associated with the biofuels but a recent report published by USA department of energy (2007) has revealed that these fuels cannot be held responsible for the increase in the greenhouse gas emissions, it is a fact that the burning of biofuels produces a large amount of carbon dioxide but the crops grown to obtain biomass for this industry neutralize this emission by absorbing carbon dioxide for photosynthesis.

2.10.1 Reduced Greenhouse Gas Emissions

It is evident from the studies conducted by Smekens and van der Zwaan (2006) that conventional fuels are responsible for increased emissions of green house gases and are responsible for global warming to some extent. The future prospects of global warming and green hose gas emissions were studied by Kohler (2006), he reported that some major developing countries such as China, Brazil and India will cause immense increase in the green house gas emissions due to rapid increase in population and transport requirements.

A recent report published by IEA (2005) has emphasized the importance of biofuels as the first alternate for conventional fuels to be used in transport, these are renewable energy resources. Ethanol and biodiesel both have very low green house gas emissions as compared to fossil fuels; the reduced emission of green house gases is considered as an incentive to increase reliance on the biofuels.

2.11 Factors responsible for promotion of biofuel policies

There are numerous factors that are driving governments to formulate policies for the promotion and development of biofuels and biofuel industry. A report published by UK department of Transport (2004) states, “The benefits [of biofuels] include greenhouse gas reductions which will contribute to domestic and international targets, potential air quality benefits (albeit limited), the diversification of the fuel sector and an additional market for agricultural products.” To sum up we can say that the most influential factors for the promotion of biofuel policies include adverse changes in the climate due to continuous use of fossil fuels, enhancement of the agricultural industry thus producing employment opportunities in the rural areas, self reliance in terms of energy requirements of the country and utilization of the resources of the country to yield maximum benefits. There are numerous socioeconomic benefits associated with the use of biofuels and comparatively they also have positive effect on the environment than conventional fuels (Faaij, 2006).

2.12 A solution to the Energy Security Concerns

Romm (2006) asserted that more than 97 % of the energy requirement so transport is fulfilled by organic or carbon based fuels; the energy security of the world is at stake since more than half of the crude petroleum reservoirs have been emptied. The ultimate fate of the conventional fuels is the extinction but the date of extinction is controversial. As pointed out by Sharpe and Hodgson (2006), the extinction of energy may lead to extinction of lie in the long run. The extinction of this cheap so本论文由英语论文网提供整理，提供论文代写，英语论文代写，代写论文，代写英语论文，代写留学生论文，代写英文论文，留学生论文代写相关核心关键词搜索。
