It can be solid, such as fuel wood, charcoal and wood pellets; liquid, such as ethanol, biodiesel and pyrolysis oil; or gas, such as biogas. The main distinction is also made between primary they are also called unprocessed and secondary processed biofuels. Let us explore them:. Observing the fact how much people should rely on biofuels it is possible to say that in the coming decade, and, perhaps, even subsequently, the great demand for agricultural feedstocks for various types of liquid biofuels will be a significant factor in agricultural markets and world agriculture.
Demand for biofuel feedstocks may help to radically change the long-term decline in real prices for agricultural commodities, leading to the emergence of both opportunities and risks.
All countries face the implications of the development of liquid biofuels, regardless of their direct participation or nonparticipation in the sector, because this process will affect all agricultural markets. The development of biofuels has its both negative and positive perspectives. Thinking about negative perspectives we see that rapidly growing demand for raw materials for biofuels contributed to increased food prices, which cast a direct threat to food security of poor net-food buyers in urban and rural areas.
Protection systems should be distinguished by accurately purposefulness and should not block the transmission of price signals to agricultural producers. Observing positive perspectives, it is possible to note that, in the longer term, increased demand and rising prices for agricultural commodities may provide opportunities for the development of agriculture and rural development.
However, market opportunities can not ensure the elimination of existing social and institutional barriers to the equal growth in the presence of factors exceptions, such as gender, ethnicity and political powerlessness, and may even tighten them. Moreover, the mere increase in commodity prices is not enough; an urgent need to ensure investment in research and productivity, to increase the stability of production, to create the institutional framework, infrastructure and to carry out sensible policies.
It is extremely important to pay special attention to the needs of the poorest and least provided groups, without which it will not be able to guarantee a comprehensive rural development. If more people start shifting towards biofuels, a country can reduce its dependance on fossil fuels.
More jobs will be created with a growing biofuel industry, which will keep our economy secure. Reduce Dependance on Foreign Oil: As prices of crude oil is touching sky high, we need some more alternative energy solutions to reduce our dependance on fossil fuels. Lower Levels of Pollution: Since biofuels can be made from renewable resources, they cause less pollution to the planet.
However, that is not the only reason why the use of biofuels is being encouraged. They release lower levels of carbon dioxide and other emissions when burnt.
Although the production of biofuels creates carbon dioxide as a byproduct, it is frequently used to grow the plants that will be converted into the fuel. This allows it to become something close to a self sustaining system. High Cost of Production: Even with all the benefits associated with biofuels, they are quite expensive to produce in the current market.
As of now, the interest and capital investment being put into biofuel production is fairly low but it can match demand.
If the demand increases, then increasing the supply will be a long term operation, which will be quite expensive. Such a disadvantage is still preventing the use of biofuels from becoming more popular.
While, this might be economically attractive for farmers but growing same crop every year may deprive the soil of nutrients that are put back into the soil through crop rotation.
Biofuels are produced from crops and these crops need fertilizers to grow better. The downside of using fertilizers is that they can have harmful effects on surrounding environment and may cause water pollution.
Fertilizers contain nitrogen and phosphorus. They can be washed away from soil to nearby lake, river or pond. Biofuels are extracted from plants and crops that have high levels of sugar in them. However, most of these crops are also used as food crops. Even though waste material from plants can be used as raw material, the requirement for such food crops will still exist. It will take up agricultural space from other crops, which can create a number of problems.
Even if it does not cause an acute shortage of food, it will definitely put pressure on the current growth of crops. One major worry being faced by people is that the growing use of biofuels may just mean a rise in food prices as well. The carbon footprint of biofuels is less than the traditional forms of fuel when burnt. However, the process with which they are produced makes up for that. Production is largely dependent on lots of water and oil.
Large scale industries meant for churning out biofuel are known to emit large amounts of emissions and cause small scale water pollution as well. Unless more efficient means of production are put into place, the overall carbon emission does not get a very big dent in it.
Large quantities of water are required to irrigate the biofuel crops and it may impose strain on local and regional water resources, if not managed wisely. In order to produce corn based ethanol to meet local demand for biofuels, massive quantities of water are used that could put unsustainable pressure on local water resources.
Future Rise in Price: Current technology being employed for the production of biofuels is not as efficient as it should be.
- An essay on the benefits and risks of the biofuel industry and their adequacy for the developing world With the constant rise of energy demands on the global market, the ever-on-the-rise cost of fossil fuel and the damage to the environment done in the last century, the effect we are more and more aware, the demand for alternative energy.
Nowadays, as the problem of greenhouse gases emissions is getting more serious, Carbon-negative biofuels represent the first.
