What Is Bio Fuel???
Bio fuels can be described as any fuel that is derived from biomass i.e. living organisms or their metabolic by-products. For example, crops such as corn and dung from living animals.
There is still something of ongoing scientific arguments about the benefits of bio fuels, we believe that the main advantage over fossil fuels (coal, oil and gas) is that the combustion of bio fuels to free the energy does not increase net emissions of CO2 levels in the atmosphere. This is because the source of bio fuel crops, for example, has already taken an equivalent amount of CO2 from the atmosphere during their growth cycle, when photosynthesis.
As long as new crops are planted in a place of the ones that are burnt, there will be no overall increment in the amount of CO2 free into the atmosphere. Then, whilst crop based bio fuels don’t descend the quantity of CO2 in the atmosphere, they are thought to be more or fewer carbon neutral.
Difference with deposits of fossil fuels like coal is that coal deposits were formed in the earth for millions of years and are considered as reservoirs of energy rather than part of the energy cycle. The burning of fossil fuels on the scale needed to meet the energy needs of humanity, in a relatively short cycle time, hundreds of years faced by millions of years, has interpreted the deposits form, and means that the combustion of these fuels adds significantly the levels of CO2 in the atmosphere. Add to greenhouse gases already present in our atmosphere, contributing to global warming.
The central benefit however probably comes from liquid bio fuel, for the production of Ethanol or bio diesel. Ethanol, a replace for fossil fuel based petrol, and bio diesel, which is exactly diesel made with crops in place of oil which is a replacement for traditional diesel fuel in diesel motor vehicles.
Neither are as efficient however as vehicles running on broadly ethanol-based fuels. Modern research indicates that prairie grasses actually take out more carbon dioxide from the atmosphere during their growing than they emit when being converted to bio fuel, meaning that they may well be truly carbon neutral.
