About bio fuels ??

Question

hi guys

i need to know the reasons why the production of biofuels is increasing ??

i Know some but i want them to fill one whole A4 paper soooo please write everything you have in mind and i'll so thankfull

Answer 1

There is not sufficient arable land to adequately feed the current world population. Each acre used for biofuel effectively causes the starvation of one person. Should biofuel production be equated to genocide? Some people think so.

Production is increasing due to government subsidies for producing biofuel.

Answer 2

$3.40 per gallon gas, ethanol can be made for $.90 and Bio diesel a couple dollars.

Answer 3

Biofuel (also called agrofuel) can be broadly defined as solid, liquid, or gas fuel consisting of, or derived from biomass. This article, however, is principally about biofuel in the form of liquid or gas transportation fuel derived from biomass. Biomass can also be used directly for heating or power. One type of biomass is wood, which is frequently used in industry, either by itself to create energy or with other combustible matter (such as coal) to burn and create heat. (Wood has been burned for millennia - as solids.)

Biofuel is considered a means of reducing greenhouse gas emissions and increasing energy security by providing an alternative to fossil fuels. However, In October 2007, Nobel Laureate Paul Crutzen published findings that the release of Nitrous Oxide (N2O) among the commonly used biofuels, such as biodiesel from rapeseed and bioethanol from corn (maize), can contribute as much or more to global warming than fossil fuel savings do to global cooling. Crops with less N demand, such as grasses and woody coppice species have more favourable climate impacts.

Humans have used biomass fuels - that is, solid biofuels - for heating and cooking since the discovery of fire. Following the discovery of electricity, it became possible to use biofuels to generate electrical power as well. However, the discovery and use of fossil fuels: coal, gas and oil, have dramatically reduced the amount of biomass fuel used in the developed world for transport, heat and power.

Liquid biofuels have been used since the early days of the car industry. Nikolaus August Otto, the German inventor of the internal combustion engine, conceived his invention to run on ethanol. Rudolf Diesel, the German inventor of the Diesel engine, designed it to run on peanut oil. Henry Ford originally designed the Ford Model T, a car produced from 1903 to 1926, to run completely on ethanol. However, when crude oil became cheaply available (thanks to oil reserves discovered in Pennsylvania and Texas), cars began using fuels derived from mineral oil: petroleum or diesel.

Nevertheless, before World War II, biofuels were seen as providing an alternative to imported oil. Germany powered its vehicles using a blend of gasoline with alcohol fermented from potatoes, called Reichskraftsprit. In Britain, grain alcohol was blended with petrol by the Distillers Company Limited under the name Discol and marketed through Esso's affiliate Cleveland.

After the war, cheap Middle Eastern oil lessened interest in biofuels. But the oil shocks of 1973 and 1979 increased interest from governments and academics. The counter-shock of 1996 again reduced oil prices and interest.

Since around 2000 renewed interest in biofuels has been seen. The drivers for biofuel use and development include rising oil prices, concerns over the potential oil peak, greenhouse gas emissions (global warming), rural development interests, and instability in the Middle East. The US president George W. Bush said in his 2006 State of the Union speech that the US should replace 75% of imported oil with biofuel by 2025.

Using waste biomass to produce energy can reduce the use of fossil fuels, reduce greenhouse gas emissions and reduce pollution and waste management problems. A recent publication by the European Union highlighted the potential for waste-derived bioenergy to contribute to the reduction of global warming. The report concluded that 19 million tons of oil equivalent is available from biomass by 2020, 46% from bio-wastes: municipal solid waste (MSW), agricultural residues, farm waste and other biodegradable waste streams.

Landfill sites generate gases as the waste buried in them undergoes anaerobic digestion. These gases are known collectively as landfill gas: this can be burned and is a source of renewable energy. Landfill gas (LFG) can be burned either directly for heat or to generate electricity for public consumption. Landfill gas contains approximately 50 percent methane, the same gas that is found in natural gas.

If landfill gas is not harvested, it escapes into the atmosphere: this is not desirable because methane is a greenhouse gas, with more global warming potential than carbon dioxide.  Over a time span of 100 years, methane has a global warming potential of 23 relative to CO2. Therefore, during this time, one ton of methane produces the same greenhouse gas (GHG) effect as 23 tons of CO2. When methane burns the formula is CH4 + 2O2 = CO2 + 2H2O. So by harvesting and burning landfill gas, its global warming potential is reduced a factor of 23, in addition to providing energy for heat and power.

PhD Frank Keppler and PhD Thomas Rockmann discovered that living plants also produce methane CH4.[citation needed] The amount of methane produced by living plants is 10 to 100 times greater than that produced by dead plants but does not increase global warming because of the carbon cycle.

Anaerobic digestion can be used as a distinct waste management strategy to reduce the amount of waste sent to landfill and generate methane, or biogas. Any form of biomass can be used in anaerobic digestion and will break down to produce methane, which can be harvested and burned to generate heat, power or to power certain automotive vehicles.

A 3 MW landfill power plant would power 1,900 homes. It would eliminate 6,000 tons per year of methane from getting into the environment. It would eliminate 18,000 tons per year of CO2 from fossil fuel replacement. This is the same as removing 25,000 cars from the road, or planting 36,000 acres (146 km²) of forest, or not using 305,000 barrels of oil per year.

You need to learn how to do your own home work!

Answer 5

It's supply and demand. Beside it takes far more fossil fuel to produce one gallon of  bio-fuel. So, it also not a workable solution financially right now.

Answer 6

I believe soy oil is not a good food product as it supports the wrong bacteria in the gut. Man needs only animal and tree oils for cooking.  As a fuel I think soy oil is perfect to run the big trucks and burn clean. The bio fuels now being made are energy inefficient to make. Corn to alcohol takes a lot of fuel to be heating the water for fermentation of the beer and then distilling etc. The best bio fuel is all research now . It is taking carbon and hydrogen from the air and making a carbon fuel like methane. Go science go! America wont  do it until we are forced to. Finally the bio fuel called pellet burner fuel is made from wood chips like you get from branches after a big ice storm. So why are cities burning it away to ash? O Hillary we need you.
