In recent years there has been a lot of interest in renewable and alternative energy sources. This has seemingly become an even bigger issue in the wake of the Japanese nuclear crisis, where the nuclear plant at Fukushima was damaged by the earthquake and resultant tsunami on March 11th. There is now a real danger that harmful radiation could escape from the site. People have always been uncertain of the safety of utilising nuclear power and such a scare only serves to heighten their concerns. That is why increasingly people are looking for alternatives. One such alternative is the use of biofuels.
What are Biofuels?
The term ‘biofuel’ refers to a broad range of fuels that are created from ‘biomass’ (see below). Biofuels are often used as an additive rather than as a ‘pure’ fuel. Bioethanol is an example of this. It is an alcohol created by fermenting the sugar components of plant materials and whilst ethanol can be used as a fuel for cars in its purest form, it is normally added to petrol to improve the emissions from the vehicle and increase octane.
Ok, so what is Biomass?
Biomass is a renewable energy source. It refers specifically to biomaterials from living organisms and recently living organisms – examples of which are wood, waste and alcohol fuels. There are actually several different sources of biomass energy, so in addition to the three just mentioned, there are: garbage and landfill gases. There are a few different mechanisms by which biomass can be converted to energy:
This involves the use of heat in order to convert biomass into an alternative chemical form. There are different forms of thermal conversion – two examples of which are torrefaction and pyrolysis.
This is quite simply where a range of chemical processes are used in order to convert biomass to alternative forms.
This involves harnessing the power of naturally occurring biochemical conversion processes. Microorganisms are used to break down biomass – Anaerobic Digestion is an example of this.
Biogas is a type of biofuel that is produced by anaerobic digestion or fermentation of biodegradable materials, including biomass. Biodegradable waste can, for example, be converted to methane – which is a renewable energy source.
So are Biofuels the answer?
It remains to be seen whether or not biofuels are a long term solution to the problems surrounding the energy industry. There are certainly discussions to be had about the impact that the production of biofuels has on carbon emissions and biodiversity, but these are certainly not the only issues.
6 reasons to use biofuels.
Biofuels is a nickname to renewable fuels from biological source, that can replace fuels that come from fossil fuels like gasoline and diesel. It is now possible to purchase or make yourself biodiesel for diesel engines or ethanol for gasoline engines. The prices are becoming closer to those of fossil fuels and there are many benefit to it. Here I’ll count 7 benefits of biofuels:
1. Availability – It is renewable. Unlike fossil fuels, biofuels can be easily produced from raw agricultural materials. These facts ensure that the reservoir of fuel will never end, and that we can keep producing it, like we produce our food.
2. Price – since the reservoir is virtually unlimited, we can assure that as time goes by, the oil prices will increase duo to the increase in demand/production ratio, while the biofuels prices will decrease duo to the progress in agriculture science and techniques. In a few years from now, it is almost certain that biofuels prices will be much lower than fossil fuels, so the sooner you start using it, the better.
3. Independence –Biofuelsare easy to produce, and propose a new prospect to fuel consumers – unlike today’s when huge company controls the fuel industry and supply, making the small consumer a slave to their will, biofuels will allow individuals and small manufacturer to get into this business and increase the competition. This is good both to the manufacturers and to the clients.
4. Healthier – biodiesel and ethanol are much safer than biofuels – they are much better to the environment, and have a great implication regarding global warming and air quality. If you care about the air that you and your children are breathing, you must take it under consideration.
5. Better to the engine. Biofuels are not only healthier to the environment, but also much better to the engines. Much research done by the automobile industry shows that biodiesel and ethanol increase the efficiency of the engine and it life span.
6. Have good political implications. At present, oil producing countries enclose a huge power in their hands, allowing them to take advantage of their power to harm other countries, and jeopardise world peace. Crossing to a different fuel source will dramatically reduce the pressure of oil deficiency, allowing many suppressed countries to flourish.
I hope that these reasons will capture your attention, to do something in that direction, making the world a better place to everyone.

There is a growing concern these days for the environment, and several countries have taken the initiative to promote the use of renewable energy to lessen humanity’s impact on the planet. Canada is one such country taking the lead in green technologies, and using biofuels is one of the steps they have taken in becoming one of the world’s leaders in the consumption of environmentally friendly fuels.
Biofuels are simply liquid fuels manufactured from plant and animal materials. Because this matter is biodegradable, it is not only capable of powering vehicles and heating homes, but the waste is then absorbed once again into the earth, nurturing new life able to provide future renewable energy sources.
Bioethanol, commonly referred to as just ethanol, is the most common biofuel currently in production. Canada’s federal government has taken note of ethanol’s potential as an alternative renewable energy and created a plan requiring gasoline to contain 5% ethanol by the end of this year. The plan would also require diesel fuels to contain at least 2% ethanol by the end of 2012. As a matter of fact, the provincial government of Manitoba has taken a leadership role in the biodiesel industry by creating mandates requiring similar percentages as those devised by the federal government that will go into effect in 2010. This precedes the federal mandate by two years. Manitoba is known for its prairie lands, the crops that grow there, and the animals that graze upon these crops. The amount of plant and animal materials available for the production of biofuels is great. Manitoba has inspired the provincial government of British Columbia to adopt similar strategies.
The corporation of Raven Biofuels Limited was established to research and develop technologies conducive to efficient and prolific use of biofuels throughout Canada, and they have identified British Columbia as a starting point. Joining Raven Biofuels International Corporation (RBIC), their goal is to pay RBIC a fee providing them exclusive rights to biofuel development in Canada. Their intent is to build the first commercial biorefinery and place it in Kamloops, British Columbia. Though it may seem as though a monopoly or trust would emerge from this partnership, the goal is to set an example and to provide guidance to other potential commercial endeavors. Municipalities have partnered with British Columbia’s provincial government to create the BC Bioenergy Strategy, which has already garnered million to fund a Biofuel Network focused on furthering biofuel energy technology not just in British Columbia, but throughout Canada.
Biofuels are when we use organic matter as fuel by converting it into power for use. By producing biofuels, this is an alternative energy source as we depend on fossil fuels. The ethanol products include under its aegis, derivatives of plants like sugar cane, and also corn and vegetable oils, all part of the biofuels umbrella. Not all of them are designed for use as gasoline, although the International Energy Agency (IEA) say that by 2025, 10 % of the world’s gasoline could be made up of ethanol products, and by 2030, it could be up to as much as 30%. At the moment, the percentage stands at just 2%.
A lot of research is going into biofuels, and it will be some time before we can refine them to make them more economic and practical enough to use. Oregon State University have done a study to prove this. Biofuels have not yet been developed which are as energy efficient as petroleum which makes up our gasoline. To put it simply, energy efficiency is how we measure the usable energy that is derived from the input energy by a certain amount. (Up till now we have not come up with any product where the output energy exceeded that of what was input). What is most important is the end product energy that has been converted and its usefulness for our society’s needs, the effort involved is what we put into the input energy so as to produce which is the end-product. A study by the OSU found that ethanol which is corn-derived was only 20% energy efficient (compared to gasoline that is 75% energy efficient and made from petroleum). Biodiesel fuel had a recorded energy efficiency of 69%. Out of the study came one positive thing: higher than nuclear energy which is effectively efficient, was cellulose-derived ethanol charted as 85% efficient.
The New York Exchange has marked a change in oil for the future, with analysts from many countries having predicted surges in the availability of biofuels, which would offset oil prices, seeing crude oil drop to prices of about per barrel on the international market. On the Chicago Stock Exchange there is more investment activity in future markets on grain, making a “steal” on the oil futures of New York, with investors expecting much better profitability from biofuels to come. By 2030, a consensus of analysts have predicted that biofuels will account for 7% of transportation for all round the world. Demand for and diesel and gasoline will slowly fall dramatically according to one energy market analyst, as government supports the use of the more eco-friendly biofuels and subsidise the manufactures of this fuel.
Many nations support the use of biofuels and its production in developement.
Brazil is the biggest in the production of ethanols that are derived from sugars. Approximately three and a half billion gallons of ethanol is produced in a year.
The greatest oil user is the United States, who already come second behind the largest producer, Brazil, in biofuels.
The European Union now have an excess of four million (British) tonnes in biodiesel production capacity, of which 80% is derived from rapeseed oil. The remaining 20% of the EU’s biodiesel fuels is marginally from palm oil and the rest comprised of soybean oil.

The recent breathtaking spike in oil prices has finally awakened professionals in the energy field to the very real need for alternatives. As a result, we are seeing liquid fuels developed from plant materials entering the market. Sugar components of various plant materials if fermented will yield an alcohol called bioethanol. Even cellulosic biomass (trees and grasses, for instance) can be used to produce this kind of biofuel. Ethanol, widely used in Brazil as well as in the United States, can, actually, be used in a pure form; however, it is used more as an additive to boost octane in addition to reducing emissions.
Biodiesel, on the other hand, is made from oils—vegetable or animal. Very often, greases are recycled and used for biodiesel. Like ethanol, it can be used in its pure form for diesel engines but is more often treated as an additive. This is the most common biofuel in Europe. The process for producing it from fats and oils is called transesterification.
In 2008, 1.8% of the world’s transport fuel was biofuel. Investment in the production of this new approach to fueling transportation vehicles for the world is expanding rapidly. It was billion in 2007. The liquid biofuels are the most popular ones for these purposes because they can be pumped, and they can directly replace gasoline. Not only do internal combustion engines run cleaner on biofuels, but pollution is also minimized. Biofuels are generally classified as first generation, second generation, and third generation.
First generation biofuels are made from sugar, starch, vegetable oil, or animal fats. Grains such as wheat are fermented into bioethanol; sunflower seeds are pressed to yield vegetable oil for biodiesel. The most common first generation biofuels:
- Vegetable Oil
- Solid biofuels
Second generation biofuels are made from non-food crops such as waste biomass, stalks of wheat, corn, wood, and certain grasses. To avoid the political issues that have arisen from the use of food that is needed for humans and animals to produce fuel, the pressure is on to develop more of these sources. Some of the second-generation biofuels under development:
- Fischer-Tropsch Diesel
- Biohydrogen Diesel
- Mixed Alcohols
- Wood Diesel
Third-generation biofuels are made primarily from algae, which can produce up to 30 times more energy per acre than land crops such as soybeans. However, they have not yet been produced commercially. These are biodegradable and will not harm the environment if they happen to be spilled. Algae can be grown agriculturally. It’s estimated that 15,000 square miles of algae would meet all the needs for petroleum fuel in the United States.
- Agricultural Algae
- Ethanol from Living Algae
- Helioculture (collection of carbon dioxide from the air using solar power)
For the non-scientist, this seems somewhat complicated, but more and more professionals in the appropriate fields are switching to this quickly-emerging industry, and we can hope that many of the problems the world faces now in obtaining energy without jeopardizing our environments will see solutions in the coming years.
Oil prices have always been a concern. Recent events, along with increased awareness of the environment, have shown us the need for the creation of alternative means of energy.
Many different options have been proposed. Nuclear power is possible but comes with obvious safety concerns. Solar and wind look like viable options, but don’t seem to be getting large amounts of support. Another option is biofuel, which involves using the energy of organic materials to replace the function of fossil fuels. Ethanol is perhaps the most widely used of these, especially in Brazil and the United States, and is used most commonly as a blend with regular fuel.
Another kind of biofuel is biodiesel, which is made from either vegetable oils or animal oils. It’s actually possible with today’s technology to take the fat that comes from the grills at McDonalds and recycle this into usable fuel! As with ethanol, it can be used purely on its own but is commonly just a supplement to be added with other fuel. It’s currently the most common biofuel in Europe. The process of turning animal and vegetable oils into usable fuel is known as transesterification.
1.8% of the world’s transport fuel was biofuel in 2008. This figure seems small, but investment in these technologies is continually increasing, and will inevitably create new technological breakthroughs and a rise in popularity. Biofuels come in many different forms, and are commonly categorized into first, second and third generation.
First generation fuels are made from food crops such as sugar, starch and animal or oil fats. Grains can be made into bioethanol, and sunflower seeds into vegetable oil and then biodiesel. These are the most common first generation biofuels: Biodiesel, bioalcohols, vegetable oil, bioethers, solid biofuels, Syngas and biogas.
From non-food crops like waste, stalks of wheat and corn we get the second generation of biofuels. Since first generation biofuels are made from edible sources, the hunt is on to create more second-generation technology that can avoid a food shortage that may occur. They include biohydrogen, biomethanol, mixed alcohols and wood diesel.
Third-generation biofuels are the most complex, and come usually from algae, which produces a large amount of energy. While the advantages of third generation fuels would be great, since it’s virtually impossible for them to cause environmental damage, the technology has so far not been sufficiently developed to allow these biofuels to be produced commercially. It’s been put forth that 15,000 square miles of algae could supply all the petroleum fuel required by the United States.
These new technological developments show just how exciting the field of biofuel is, and the great benefits it can provide to the environment. The current environmental problems and massive fuel prices could perhaps be fixed forever with the further development of second and third generation fuels. Who knows what will be powering us fifty years from now?

As the world’s attention has turned to renewable energy as a means to aid in the maintenance of the environment, Germany has taken charge as a leader in biofuels. Biofuels are often used to power automobiles and other machinery. They are derived from animal waste or from plant matter such as grain or rapeseed oil. Harmful emissions from fossil fuels are thus avoided.
In an effort to revolutionize biofuel use and technology, Germany decreed that 20% of all fuel consumed would be biofuel by the year 2020. A new fuel known as E-10 was supposed to have been introduced in 2009, made up of 90% ethanol. Ethanol is a renewable energy alcohol made from the fermentation of sugar. Unfortunately, the German Automobile Club found that nearly 3.7 million cars were unable to convert the fuel into power. The original estimate was that only around 1 million cars would be affected. Critics of the plan to accelerate the use of first generation biofuels like ethanol propose that if more crops are used to produce biofuel in Germany, then the price of food crops would rise. In addition, the demand for sugar cane imports from Brazil would threaten more rain forest acreage. They found the news that the ethanol revolution had hit a snag encouraging.
However, this obstacle has not stopped Germany’s biofuels industry. In fact, the nation is nearly ready to start commercial production of biofuels this year. A plant built by Choren Industries is in the final stages of construction in Freiburg, a city in the southern part of the country. Using wood-based products, the goal is to produce 15,000 tonnes of biomass-to-liquid gas, a second generation biofuel. Freiburg is already renowned for its recycling efforts, and with the addition of a biofuels plant, they will certainly gain further recognition as an eco-city. As long ago as 1992, Freiburg city council passed a resolution allowing for only low-energy buildings to be constructed on municipal land.
Choren Industries plans to study the political climate in Germany before constructing larger biofuels plants. Although they do not produce first generation biofuels from renewable energy materials such as palm oil and rapeseed oil (keeping food costs down), production of second generation biofuels from wood is costlier to produce. Choren is more interested in working in cooperation with German citizens than forcing biofuel plants upon them. When it comes to the renewable energy of biofuels, Germany wishes to lead by example, not by force.
