Advantages and uses of biofuels essay

Manure is another source for biofuels, and this material is widely available.

Problems with biofuels

It only makes sense to use fertilizer if we want to get the most yield per area. This is especially important when dealing with food crops. Disadvantages Despite the many positive characteristics of biofuels, there are also many disadvantages to these energy sources. However, the process with which they are produced makes up for that. Microalgae is a photosynthetic organism that can produce proteins, carbohydrates, and lipids in high quantities in a short period of time. This means they are a safer alternative to lower air pollution and to preserve atmospheric quality. This necessarily destroys animal dwellings, microcosms micro ecosystems , and reduces the overall health of a region's natural resources. Manure is another source for biofuels, and this material is widely available. Availability of Biofuels Unlike fossil fuels, biofuels are a renewable energy source. Biofuels produce significantly fewer toxins and less carbon output. Land Use Changes This one is little more difficult to understand, but you can think of it as akin to deforestation. Biofuels not only help a struggling economy by providing jobs but also helps in reducing greenhouse gases up to much extent by emitting less pollution. Renewability: It takes a very long time for fossil fuels to be produced, but biofuels are much more easily renewable as new crops are grown and waste material is collected.

On the whole, the net impact on acid rain production is usually negative, meaning biofuels can reduce acid rain. The other problem to consider is land use.

advantages and disadvantages of biodiesel pdf

A biofuel is a liquid, solid or any gaseous fuel derived from organic matter such as waste plant and animal matter. People ask what about the cars? Studies show that the machinery needed to cultivate the crops emits large carbon emissions.

10 advantages of biofuel

Potatoes in the U. They offer raw material for industries ranging from plastic to pharmaceuticals to laboratory science. Unless more efficient means of production are put into place, the overall carbon emission does not get a very big dent in it. With more development and research, it is possible to overcome the disadvantages of biofuels and make them suitable for widespread consumer use. Their applications go well beyond energy. However, the cost of research and future installation means that the price of biofuels will see a significant spike. Renewability: It takes a very long time for fossil fuels to be produced, but biofuels are much more easily renewable as new crops are grown and waste material is collected. Another issue with biofuel use and production is the US has changed mandates many times because the production has been taking longer than expected. Water use: Massive quantities of water are required for proper irrigation of biofuel crops as well as to manufacture the fuel, which could strain local and regional water resources. Land Use Changes This one is little more difficult to understand, but you can think of it as akin to deforestation. This results to more employment opportunities, especially in rural areas. The second way that damage is done is in the carbon debt created. Traditional fuels emit greenhouse gases when burned, polluting the environment and worsening the climate change problem.

For starters, energy has to be invested into growing the crop itself. Environmental Impact This category is tricky because biofuels are very similar to hydrocarbons and have some of the same emissions problems that standard fossil fuels have.

There are several advantages to using biofuels as an energy source.

environmental benefits of biofuels

Their applications go well beyond energy. This limitation also means that certain feedstocks are out of the running for replacing fossil fuels. The best way to view fossil fuel energy is as the source that brought humanity into the twenty-first century.

An abstraction of availability is delivery infrastructure.

10 disadvantages of biofuel

Even though the land is being replanted, a native forest is almost always better at removing CO2 from the atmosphere than a biofuel feedstock, in part because the CO2 remains trapped and is never released by burning as with fuel stock. Biofuels are made from many different sources such as manure, waste from crops and plants grown specifically for the fuel. Finally, fossil fuels are inexpensive and have uses beyond their applications to energy. Plant based fuels comes form renewable source, can be grown anywhere and have lower carbon emissions as compared to fossil fuels. In fact, ethanol is already cheaper than diesel and gasoline. This ends any dependence on fossil fuel resources, which are geographically limited to only a few places in the world. Discussions on the characteristics of feedstock, the methods used in the production process, a comparison of renewable hydrocarbon fuel with biohydrogen, biodiesel, bioalcohol and biomethane as alternative fuels, the industry commitments and collaborations and future outlook and recommendations in this field are also included. Potatoes in the U. Constantly rising prices may make the use of biofuels as harsh on the economy as the rising gas prices are doing right now. Easy To Source: Gasoline is refined from crude oil, which happens to be a non-renewable resource. Of course they do. But can biofuels really supply enough fuel, especially when there is an ever increasing demand?

Such a disadvantage is still preventing the use of biofuels from becoming more popular. Shahin Sayani South University Dr.

Disadvantages of biofuel

An abstraction of availability is delivery infrastructure. Cost Benefit: As of now, biofuels cost the same in the market as gasoline does. The major driver of this increase in hunger risk comes from increases in food prices that will result from the fact that agricultural land can "earn more" if it is planted with biofuels. If more people start shifting towards biofuels, a country can reduce its dependance on fossil fuels. This organism was recently discovered in the rainforests of northern Patagonia , and has the unique capability of converting cellulose into medium-length hydrocarbons typically found in diesel fuel. In addition, cutting forests to grow crops for biofuels adds to carbon emissions. Production is largely dependent on lots of water and oil. The Renewable Fuel Standard RFS set by congress for was pushed back to at best to produce million gallons of pure ethanol not blended with a fossil fuel. Economic Security: Not every country has large reserves of crude oil. And if the supply and demand for this alternative energy source will increase, they can become even cheaper.
