Replacing petroleum the negatives and positives of various biofuels

One of the main advantage of using biodiesel is that can be used in existing diesel engines with little or no modifications at all and can replace fossil fuels to become the most preferred primary transport energy source.

Since biodiesel is produced from cropsan increase in demand for biodiesel leads to increase in demand for suitable biofuel crops.

Less Toxic than Table Salt Being derived from vegetable oils, biodiesel is naturally non-toxic. Biofuels are made from many different sources such as manure, waste from crops and plants grown specifically for the fuel.

There is concern that using valuable cropland to grow fuel crops could have an impact on the cost of food and could possibly lead to food shortages. At this time, the data are insufficient for users to conclude anything about the average effect of B20 on NOx, other than that it is likely very close to zero.

A number of analytical studies are beginning to assess the changes in land use to be expected from increased biofuel demand, but little empirical evidence is yet available on which to base predictions on how yields will be affected — either directly or indirectly — or how quickly.

To refine biofuels to more efficient energy outputs, and to build the necessary manufacturing plants to increase biofuel quantities, a high initial investment is often required, making its production currently more expensive than other ways to fuel cars, even though this could change in the future.

Reduce Dependance on Foreign Oil: Grown, Produced and Distributed Locally Worldwide, energy security is becoming a hot topic in government and society. When the technology is available, many of the disadvantages will be minimized and the market very clearly has potential.

Explanation of Emission Types Particulate Matter Black Smoke Emissions of particulate matter have been linked to respiratory diseases and are generally considered to be a human health hazard. Biodiesel is not distributed as widely as petroleum diesel.

But in other regions, the same plants would be impossible -- or extremely costly -- to grow. Even if this problem could be addressed, it would not eliminate the huge environmental impacts that fossil fuels have, including everything from oil spills to global warming to acid rain.

This problem is considered in more detail in the disadvantages of biofuel, but the main point is that carbon is produced to clear that land and the benefits of the plants on the land are lost. They project that maize area devoted to ethanol production in the United States of America could increase to So, advantage number one for fossil fuels would have to be infrastructure.

The infrastructure still requires more boost so that it is adopted as most preferred way to run engines. The areas where there is water scarcity, production of crops to be used in making of biofuels is not a wise idea.

Pollutants from gasoline engines when released in the air, form smog and make thousands of people sick every year. When the oil is extracted and converted to fuel using chemical process, the result can vary in ability to produce power.

It is therefore safe to handle, store and transport. Constantly rising prices may make the use of biofuels as harsh on the economy as the rising gas prices are doing right now. They are cleaner fuels, which means they produce fewer emissions on burning. It may not solve all problems in one blow but a nation can save billions by reducing their usage on foreign oil.

However, the overall cost benefit of using them is much higher. The feasibility of achieving this advantage remains to be seen. Large scale industries meant for churning out biofuel are known to emit large amounts of emissions and cause small scale water pollution as well.

For comparison, diesel fuel delivers only 0. More jobs will be created with a growing biofuel industry, which will keep our economy secure. Fossil fuels when burnt release greenhouse gases like carbon dioxide in the atmosphere that raises the temperature and causes global warming.

They offer raw material for industries ranging from plastic to pharmaceuticals to laboratory science. Disadvantages of Biodiesel Variation in Quality of Biodiesel: Biofuels are produced locally and thousands of people are employed in biofuel production plant.

When oil is extracted from underground, it has to be refined to run diesel engines. Many crops which yield oils used for biodiesel production can be a beneficial rotation for other food crops, including soybeans when used in a traditional corn rotation, and canola when used in a wheat rotation.In this article, the term fossil fuels includes coal, petroleum and natural gas.

InThe U.S Energy Information Administration (EIA) concluded that 86,4% of the primary energy consumption in the world can be sourced back to fossil fuels. Below you will find the most important fossil fuels pros and cons.

Biofuels: Pros and Cons

Replacing Oil: Alternative Fuels and Technologies. The Strategic Petroleum Reserve: A Short-Term Response Replacing Oil: Alternative Fuels and Technologies The advantages enjoyed by petroleum divide the potential competitors into two camps-liquid biofuels (ethanol and biodiesel) that can be used in ICEs and other energy sources.

Replacing annual crops with perennial feedstocks (such as oil palm, jatropha or perennial grasses) can improve soil carbon balances, but converting tropical forests for crop production of any kind can release quantities of greenhouse gases that far exceed potential annual savings from biofuels.

10 Disadvantages of Biofuels. by Matt Cunningham START COUNTDOWN NEXT. Start the Countdown. Biofuels, made from crops such as corn, can have negative economic and environmental effects, as well as positive ones. comes from a renewable resource and often produces cleaner emissions than petroleum-based fuel.

Despite the many positive characteristics of biofuels, there are also many disadvantages to these energy sources. Energy output: Biofuels have a lower energy output than traditional fuels and therefore require greater quantities to be consumed in order to produce the same energy level.

Disadvantages of Biofuels. 1.

significance of petroleum oil Essay Examples

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.
