The Biofuels(Green Gold)


The definition of biofuels:-
Is a clean fuel production depends mainly on the conversion of biomass, whether represented in the form of grains and agricultural crops such as maize, sugar cane or in the form of oils and animal fats such as soybean oil and palm oil to ethanol or alcohol organic diesel, which means it can be used for lighting and operation of vehicles And the Department of generators.

The current biofuels:-

However, the major advantage of biofuels that will hopefully develop and expand, it also can be produced from waste, animal waste and plant residues, whether or animals and their droppings were from rice straw and sawdust, as can be produced from algae and aquatic plants and other fast-growing non-food items such as the value of jatropha and jojoba.

In terms of the possibilities and benefits of currently available sources of renewable energy, whether from the sun, wind, waves or other remains of biofuels, despite the controversy surrounding him, is the most capacity to support global energy security, and this for several reasons:-

First: - its cheap cost and the possibility of production at any time and any part of the land, because of the availability of its raw materials and is not constrained by any geographical or natural factors, a major feature missing from other renewable sources of energy such as solar energy, which are linked by the brightness of the sun, and wind energy can not be provided throughout the months of the year, and hydropower that are related to the existence waterways and coasts freely, which is not available for all countries.
Second: - The cleanliness of the source and did not harm the environment or climate and growing so in hopes of ridding the world of a large part of the current environmental problems, Vmahroqat biofuels compared with fossil fuels is characterized by the launch of less content of carbon dioxide, the leading cause of global warming, and lead , one of the toxic and carcinogenic and other chronic diseases, and the majority of oils, biofuels, degrade gradually and automatically, which means that impact negatively on the quality of the environment and the media surrounding ecosystems.

The reality of these benefits was not strange that the world is witnessing a real boom in the biofuels industry over the past years, in America's largest producers of fuel ethanol production, for example, jumped from 53 million liters in 2003 to 280 million liters in 2005, and in Brazil Sweden and Germany resulted in growth of productive capacity to its transformation to exporters of the fuel, and, some have called the proposal to establish a special assembly in these countries and all other countries exporting biofuels, the Organization of energy, particularly along the lines of OPEC oil, the world growth rate in the energy industry of biofuels about 15% annually, and is expected to increase global demand by 30% during the coming period, all indicators are very important, and illustrates the status and prosperity achieved by the industry.

Dreams biofuels promised:-

Established that the increasing demand for biofuels and the viability of this renewable source to fill the existing vacuum in energy sources will be based on the most important result: -
First - is the throne of Achah energy future green color instead of the current black. This means the other hand, fading star nations and kingdoms of many economic, as long as the oil sits Good stock and boosted its coffers, and also means other emerging high power.
Secondly - to uphold the value of agricultural land and the creation of a new renaissance of global agricultural and comprehensive, it could biofuels and increasing demand for agricultural products, contribute to the rehabilitation of many of the deserts and arid lands, and boost agricultural production around the world and expanded horizontally and vertically.

Some of the problems of biofuels expected:-

1-Agricultural land-use change and rush towards the expected conversion of productive agricultural fields of food crops to large mines for energy crops promised, and the consequent disruption of the world's agricultural biodiversity and forests and encroaching on protected green areas, increased soil erosion, and high levels of water pollution and air because of the large quantities of pesticides and fertilizers required for cultivation of energy crops especially maize.
2-For developing countries dependent on imports for its food needs of poor countries usually receive grants and international assistance in the form of food aid, these fears are no doubt will turn into nightmares spirits because of the escalating prices of food crops as a result of the growing demand for grain and agricultural products, and due to lack of the surplus of oil exporters, which in turn threatens global food security directly.
3-Escalation of the conflict on water resources due to the increasing need for water, both for use in irrigation of crops, corn and sugar cane producers of energy, or in the process of biofuel production itself, where the production cost, for example one liter of ethanol from corn is about 4 liters full of water.

Based on this expected "World Institute for Water Resources Management", in a recent study it, to face both China and India, for example in the scarce water sources by the year 2030, if they continued to present their plans to produce biofuels.

However, it can not of course be quite so gloomy or negative when talking about the production of biofuels from waste plant, animal or agricultural wastes and other wastes, because of this harmony with environmental safety and food security of the world, but this trend, will depend on in any case the development of current technology manufacturer of biofuels.

Trends Mtaxan fully represent the dreams and nightmares of this emerging industry, and separated by only a hair one minute, is in the quality of biomass to be used in the production of biofuels in the future, whether they are derived from the basic food crops such as corn, wheat, soybeans, food and all the poor people of the world, or source of animal and vegetable waste was not lacking in the environment, and human needs.
