Energy Derived from Biological Organisms

Bioenergy is derived from biological sources such as wood, waste, and alcohol fuels. In a narrow way it is a synonym to biofuel; the fuel derived from biological sources. In its broader sense it includes biomass which is the biological material used as a biofuel. This is a common misconception among masses, as bioenergy is the energy extracted from the biomass, as the biomass is the fuel and the bioenergy is the energy contained in the fuel.

Burning wood for heat is a good example of Bioenergy. In more complicated terms, bioenergy can be formed by using genetically modified bacteria to create cellulose ethanol. Although oil and coal are made from organic mater, they are not considered to be bioenergy as they were not living recently.

Bioenergy used in real-life situations

Liquid Bioenergy; Bioethanol and Biodiesel, can be used to replace existing petrol and diesel, with little changes to the engine. Some major vehicle producers already support this technology and it is becoming more widespread.

Bioethanol is generated from fermenting the sugar or starch portions of agricultural raw materials. Sugar cane, beet and maize are commonly used to produce fuel. Biodiesel comes from edible plant oils. Waste cooking oil can be used to create biodiesel. Biogas is produced from methane and carbon dioxide, and is produced from biomass, such as manure, sludge, sewage, feedstock, and other biodegradable waste. Biogas is used to produce electricity, or mixed with natural gas to be used in vehicles.

Bioenergy is been seen as a potential suitable alternative for fossil fuels in some applications, although the technology available is not quite suitable yet.

Bioenergy is ideal for using in locations where there are not much access to fuel import. Plants can be grown specifically be used a as fuel, and can be grown exactly where they are needed, which dramatically reduces the financial and environmental costs and the safety risks associated with transporting and storing fuel.

Advantages and disadvantages of bioenergy

Although by burning or conversion of biomass the pollution of atmosphere are not fully reduce. Nevertheless it have some major benefits .In many regions, biomass is more consistent than solar or wind energy. This is because, the solar and wind energy are done by manufactured technology, while the energy in plants is captured and stored. Another advantage is that bioenergy is produced by organic waste material which helps to save the environmental and economic costs of their disposal. Perhaps the most important advantage of bioenergy is that it is a potentially renewable natural resource that would help supply energy needs indefinitely.

However, there are some disadvantages to using bioenergy. Biomass has small energy content for bulk usage than fossil fuels. Thus the costs of labor, transportation, and storage are comparatively higher.

Perhaps the major difficulty with bioenergy is with recycling. People will not demand bioenergy until there is a large cost saving in doing so, but there will not be much savings until there is a much larger demand for bioenergy, or the non-renewable sources become significantly more expensive.
