Advantages And Disadvantages Of Biogas

In the current era, fossil fuel is a necessity in our everyday life, for not only it is used as an energy source, but also due to the high rate of dependability on the fuel itself. The recent drop in oil prices caused an enormous impact on the world economy, especially to the countries that are highly dependent on the fuel industry. The United States also are affected by this situation. One suggestion and a major change, in order to reduce the high dependency on the fossil fuel and to overcome the problems related to the usage of fossil fuel, is to start the wide use of biofuel as the fossil fuel replacement. The impact of this change, and also a huge improvement, not only will help to stabilize the economy, but also can help in reducing the greenhouse gases in the atmosphere.

Biomass also generates electricity and also provides heating which is direct can be renewed into biofuels as a substitute for the fossil fuels

However, despite its many advantages biomass still has many disadvantages. Firstly it is not as efficient as fossil fuels, for example the ethanol produced for cars via biomass is not even close to the efficiency of petrol and does damage to engines over time. It also has the potential to harm the environment through increase of methane gases which are produced as a bi-product if animal and human waste is used. Biomass also requires a large distance away from residential areas in order to burn it and a large amount of fuel in comparison to other energy sources which can have dramatic effects if large portions of forests are cut down to provide lumber.1

The renewable energy that the Georges produced through the bio-gas is set up to offset the farm's electricity use and/or sell the power at wholesale rates to the local utility. In the article it stated that the change to bio-gas results in less odor-causing compounds in manure in a liquid storage system and the breaking down of manure in the digester changes the organic nitrogen into ammonium which is when spread on the fields it’ll become more readily available when consumed by the plants allowing for less nutrient runoff. Also reduces weeds appearing in the fields causing less weeds growing with crops. Another great thing about the digestion process it also reduces methane, a greenhouse gas, emissions (basically global warming) which would otherwise remain in the atmosphere for 9 to 15

With the rise of nonrenewable fuels prices and the estimated decline of availability in the not so distant future it is very clear that the only answer to this problem is to implement the use of renewable resources. Renewable resources are very versatile and can reduce pollution of the environment and can in the long

In order to convert the cow manure into energy we would need an anaerobic digester. An anaerobic digester gets its name from the anaerobic microorganisms that thrive in its oxygen free tank. In fact, this is how an anaerobic digester works. Its oxygen free tank allows anaerobic microorganisms to exist in abundance. The anaerobic microorganisms then use the manure for energy, and in the process produce methane gas as a byproduct. After some treatment, the methane gas can then be burned in order to produce electricity. My team and I have decided to buy

To solve the rigorous threat to earth from global warming, bio-fuels serve as the most feasible source of energy all over the world. The environmental and economical performance of bio-fuel as compared to fossil fuel was analyzed by full Life Cycle Analyses (LCA) in Spain. The Spanish government CIEMAT, carried out two LCA’s so as to compare ethanol-ethanol mixtures with gasoline, and biodiesel-biodiesel mixtures with fuel oil according to ISO 14040-43 standards, these standards evaluate energy and mass balance for two or more objects. It was concluded that carbon dioxide emission during utilization of bio-fuel are lower than fossil fuel and bio-fuel requires less primary energy to be processed than fossil fuels. Bob Dinneen, President and CEO of the Renewable Fuels Association submitted the letter to the editor of The Gazette in which he marked that “On an environmental level, conventional ethanol is reducing greenhouse gas emissions by 34% compared to petroleum, including hypothetical land use change emissions” (qtd. in renewable fuel association). As the raw material for

For over forty years now, scientists and researchers have been tirelessly searching for an alternative to fossil fuels. Biofuels have become an interesting contender in the search for the replacement of the non-renewable energy source. Biofuels have been used throughout history for over thousands of years. There is a large debate over biofuels and its true impact on the environment. Those involved in the discussion debating whether biofuels have any real overwhelming benefits compared to fossil fuels could argue for its usage. According to recent research performed by the University of Michigan, biofuels may not be the best alternative for fossil fuels. Regardless of its impact on the environment, biofuels are becoming more popular particularly when the price of oil rises.

The project’s hypothesis is: if the type of biomass is vegetable peels then the amount of biogas produced will increase. This project tests the amount of biogas produced when cow manure is combined with different types of biomass (in this case, mashed bananas and vegetable peelings). It is an interesting project because studying how biogas is produced, it is possible to see how this chemical reaction happens. Biogas can be used for cooking, heating, and after going through a transformation process it could be even used as fuel. If studied more, biogas could have more functions.

Poop is just one of the many biological materials, called biomass, that has the potential to create bioenergy. Burning wood is the oldest kind of biomass energy used on Earth. Poop is considered a biogas product, because it produces gas. Biogas can also be produced from crops such as corn, wheat, sugarcane, as well as agricultural waste products and algae. The composting process of all biogas material produces the gas that can potentially help power the world and have a positive impact on climate change.

Hence, biofuel is a recent scientific research undertaken in Australia and will be the greatest benefit towards society and the environment. As biofuel can help contribute environmentally through lowering levels of pollution, it also benefits the society by offering economic stimulation as well as

Sustainability is an issue the whole world is facing but in particular it is become a big problem in the livestock industry. Greenhouse gases are the cause and in order to preserve the planet for future generation’s changes must be made. Methane is the greenhouse gas which produced by livestock. Methane is approximately 30 times worse for the environment than carbon dioxide as it is a heat trapping gas. If sustainability needs the achieved in the Livestock industry than the issue of methane must be taken care of sooner rather than later.

Another pro argument of deforestation is the issue of fuel wood in rural areas. The use of fuel wood in the growing cities contrasts strictly with the more familiar patterns of rural areas. The growth of energy used in rural household still dominates the energy budgets of many developing countries, especially in the poorer countries such as Nepal, Bangladesh, Ethiopia and Nigeria. Most fuel wood is used in the household. The concept of an energy transition, however, is central to any understanding energy in urban areas. As

Unlike gasoline or diesel, biofuels release little pollution. It can also be used to produce electricity by heating water using biofuels and using the steam produced to rotate a turbine. Another method is to allow the biofuel to decay and produce methane. Methane is commonly used as fuel for car, heating, cooking, and producing electricity.

This essay focuses on two renewable energy resources. First of all, biofuel is now accepted as alternative energy in worldwide. The figures continue upward trend in the biofuel production. ‘An annual growth rate of 6.8% from 2006 to 2030 is expected for total biofuels consumption in the transport sector’ (International Energy Agency: 2008 cited in Zhou, et al., 2009:S11). Significant leaders of the biofuel market are Brazil, the United States and the European Union. The results of research indicated that 92% of the world’s ethanol is produced by Brazil and US together, while 90% of the world’s biodiesel manufactured by the EU. In addition, several developing countries in Asia such as Indonesia, Malaysia, Thailand, and the Philippines have an enormous potential for biofuel production. Now these countries are
