Biofuels: Pros and Cons

Biofuels: a good alternative?

Chose second generation biofuel!

Chose second generation biofuel!

There has been much discussion about the pros and cons of biofuels as an alternative for fossil energy. I am very much in favour of developing the so-called second generation of biofuels which are produced from plant rests and branches. The current biofuels are made from the edible parts of plants such as the current biofuels. In my opinion this is indeed a form of green energy, but not the right kind.

Why should we use biofuels in the first place? This seems pretty obvious. The amounts of oil and gas that are present in the earth have been formed during four-hundred million years. These resorts of oil and gas are made from tiny plant and animals rests. Human kind is now in the act of completely emptying this resort of oil and gas. It takes us no more than four hundred years to do so… Basically, and this is astonishing, we are using daily (!) what has been formed in the soil during two thousand years. The demand for oil and gas is now huge, and will only increase. Countries such as India, and China are demanding more and more fuels. In a time span of one or two centuries, our descendants will look back on our time as the couple of hundred years that we managed to empty the entire amount of fuels present in the earth! This being said, we urgently need to look for alternative, green energy.

Biofuels seemed the logic answer!

Biofuels seemed the perfect answer because they were made of rape-seed a.o. that could be planted over and over again. In addition, the carbon dioxide produced by cars would be transformed by the growing rapeseed. This seemed a perfect solution to our increasing demand for energy..

What do we expect from these types of green energy? They need to be ecologically-friendly, i.e. they should not cause a carbon dioxide footprint and can be produced endlessly. In addition, there should not be any negative side effects.

There are some arguments strongly against these biofuels produced from for instance rapeseed. First, the amount of agricultural land needed to produce the necessary rapeseed is impossibly large. A car in motion uses as many calories per hour as five hundred people. In order to produce a mere 5% of gasoline and diesel, we would need to evacuate an area as large as the entire part of The Netherlands north of Amsterdam and sow rapeseed. For human kind this is no less than a disaster. It increases the price of food for poor people. What is even worse, the production of biofuels do not even reduce the carbon-dioxide footprint. Its production costs a lot of Co2, even more than is now caused by using gasoline.
Last but not least, its production costs a lot of water which to a large extent comes from underground stocks of water that are not endless.

According to the European Union we need to add biofuel to gasoline and diesel. By the year 2020 this should be 10% of what we are putting in our engines. This measure should reduce the output of greenhouse gases. This seems a wrong measure, unless we will be able to produce a second generation of green energy such as biofuels made from non-edible plant rests and branches.

I suppose we all want to reduce our carbon footprint and are in favour of second generation biofuels. Why? Because this is good for the environment. There are many people out there who would want to take a first step in order to make this world a better place. Why not consider taking a tiny step and get yourself a solar charger? I will let you know when we can start using good biofuels in due course!





Biofuel: Second Generation

Biofuel: second generation biofuels are the future!

Let's wait for second generation Biofuel

Let's wait for second generation Biofuel

Chemical company DSM is working on producing energy from plant rests, belonging to the category of green energy called second generation biofuel. One of their directors, Feike Sybesma: “We are on the brink of a green revolution”. This week the oil prices were at an all-time record high, with Brent oil breaking the previous record price of 2008. Therefore it is attractive, and even necessary, to look for alternatives for fossil energy.

Currently, biofuel is produced primarily from the edible parts of crops. Since this is a highly debatable issue, research is now being done on a so-called ‘second generation’ biofuel, i.e. fuel made from the rests of plants. We cannot possibly have food prices for poor people rise as a consequence. This is what is happening at the moment. And this is unacceptable. Second generation biofuel seems to have less problems in this area. The fibres of plant rests of corn and sugar-cane are transformed into sugars with the help of enzymes. These sugars are used as food for micro-organisms whereby ethanol is being produced which in its purest form is flammable and can be used as fuel. A very environmentally friendly type of green energy!

Biofuel from the corn region

In the corn-belt, the corn region in South Dakota in the United States a large plant is going to be built in which rests of corn will be transformed into ethanol. The United States want to be independent of import of oil supplies.

Indeed, we are on the brink of a green revolution; it is estimated that the US government will produce 600.000.000.000 liters a year by the year 2022. According to the International Energy Agency 27% of all transport fuels in 2050 will be biofuel.

In Brazil a lot of cars are already driving on biofuel from sugar cane. The United States are second, and then Europe. It is estimated that the amount of cars fuelled by second generation biofuel will increase rapidly. This is a development in the area of renewable energy and green energy that certainly helps a lot to safe the earth! So, biofuel as it is nowadays is unacceptable. We will have to wait for second generation biofuel.
