The novel of biofuels.
In contrast to traditional oil or gas biofuels are produced from renewable biological material, such as plants as well as different kinds of biological waste. You want me to mention a few examples of bio fuels right now, don’t you? OK, they are bioethanol, biodiesel, biogas and so on. Let’s talk about them.
Bioethanol is a substitute for gasoline. It is produced from crops mostly wheat. But it’s also possible to obtain this substance from sugar, beet, and soybeans. Biodiesel is a sort of biofuel substitute for diesel. It’s obtained from oil crops mostly seed reps. These two items mentioned above are so-called first-generation biofuels, since they are derived from raw material that can be used in food production. Biogas is a kind of biofuel replacing natural gas. It is obtained from organic waste, including livestock waste. For example in the United Kingdom biogas is produced from animal waste.
Now let’s face some advantages of using biofuels. The main practical use of alternative bio-fuel is that under certain restrictions they can be combined with the traditional fossil fuels and used in the existing energy systems such as engines of cars and trucks. Moreover biofuels are supposed to be a renewable resource, so it is relatively cheap and reliable source of energy. Secondly, biofuels give much less greenhouse gases.
There’s so-called a second generation of biofuels. I mean synthetic fuels. Although it is derived from biomass it simulates the chemical characteristics of fossil fuels. This allows to be more deeply integrated into the existing fuel system. It can also be made with the greater share of “wood” biomass such as straw.
It is becoming clear that the source of biofuels drastically affects the extent to which it is appropriate. The best biofuels could provide 10 times more energy than the energy involved in their production. And at the same time they give only a quarter of the amount of greenhouse gases. Ethanol derived from sugarcane in Brazil is often considered to be an example of “good” biofuels. In contrast to this good biofuel mentioned above the worst examples of biofuel require more energy to be inputted in production and furthermore they emit a lot of greenhouse gases. The increase in greenhouse gas emissions can not be directly connected to the fuel itself. For example, the increase of gas emissions evolve during forest fires, organized for clearing agricultural lands. By the way biodiesel made from palm oil produced in Indonesia is often considered to be an example of “bad” biofuels.
But any way it’s obvious that there’s a need to develop viable biofuels and standards of their quality to raise the effectiveness of each type of fuel. It goes without saying that the general usage of biofuels is going to maintain its rise in the nearer future.
It is truly fantastic how talented we get when the time comes to be more well-balanced about energy. The energy crisis that is rumored about pushed many people to inventing new ways of taking care of energy issues. One of the examples - wood pellets which are really effective and ecologically smart.

Biofuel invasion.
For the last time in the world you can hear frequent talks about the need to replace oil, coal and gas to biofuels. But the matter is that only few people are able to understand the situation. Sometimes you can find stories about the miraculous substances, completely non-polluting and more efficient than gasoline, kerosene and other fuels.
In reality, there’s nothing new in these biofuels. Biofuels have been being used for ages and for many reasons they are still considered to be the sole source of heat and a means of cooking in the whole world. The main biofuels is supposed to be wood, and its so –called environmental-friendliness is not obvious at all because in most cases you don’t think about all hazards of deforestation.
However, now under the term of “biofuels” wood is rarely meant. Now more high-tech products are derived from crops or waste of recycled plants and animal materials. Everything is all right with their renewability. But at the same time it’s a little more difficult to deal with emissions. Some people tell that biofuels are less harmful for the atmosphere, while opponents argue that the combustion of biofuels is accompanied by the same products typical for combustion of fossil fuels.
Biofuels are that kinds of fuels made from biological raw materials, obtained as a result of any processing plants such as corn, wheat and so on. Certainly there are liquid biofuels such as ethanol, methanol, biodiesel and solid ones such as wood, straw, pellets. And don’t forget about gaseous biofuels such as biogas and hydrogen. The growing demand for biofuels is forcing farmers to reduce the area for food crops and to redistribute them in favor of biofuel. It’s considered to be a very serious weak point of biofuels.
For example, for the production of ethanol from corn feed grains are used but before this they were produced to feed livestock and poultry.
According to the calculations of economists from the University of Minnesota, as the result of biofuel boom the number of hungry people on the planet by 2025 will increase up to 1.2 billion people. It’s scaring isn’t it? Food and Agriculture Organization (FAO) in its report for 2005 says that the increase of the consumption of biofuels can help diversify agricultural and forestry activities and improve food safety, promoting economic development. Production of biofuels will allow developing countries to create new jobs, reduce their traditional dependence of imported oil. Besides this the production of biofuels will bring new lands into circulations which are out of use by this moment. For example, in Mozambique, agriculture is conducted on 4.3 million hectares to compare with 63.5 million hectares of potentially suitable land. It’s up to you to make conclusions in this case.
It is truly amazing how gifted we get when the time comes to be more well-balanced about energy. The energy crisis that is promised to ahead pushed many people to inventing alternative ways of taking care of energy issues. One of them - wood pellets which are really great and ecologically smart.

The biomass tragedy.
In reality, there’s nothing fundamentally new and extraordinary in biofuel. The matter is that this stuff is used for just for many years. And for many people of the world still remain their everyday source of energy for their household needs.
Firewood is the oldest fuel used by mankind. Currently, the production of firewood is a great concern though it takes some time to let new trees grow up. But if all our progressive humanity cuts out all the forests throughout the world then what is going to be left of our green planet. However, in our time the word “biofuel” means wood very seldom. This term is usually used to denote high-tech products derived from crops or waste recycling plant and animal materials.
One of the main advantages of biofuels is known the reduction of greenhouse gas emissions. This, however, does not mean that when burned this produce less carbon dioxide although it is possible. A return of carbon to the atmosphere, previously absorbed by plants, doesn’t spoil the carbon balance of the planet. Fossil fuels are another matter. The matter is that carbon is typical for their composition for millions of years. When it gets into the atmosphere, the concentration of carbon dioxide increases.
In regard to harmful emissions, biofuels win not so considerably to compare with oil. Most studies show that biofuels provide reduced emissions of carbon monoxide and hydrocarbons. In addition, they contain almost no sulfur. Fuels from bio-products are offered in a great variety. These are biogas and methane, obtained by decomposition of organic residues, bacteria, and solid fuels. But most of talks are devoted to biofuels for cars such as ethanol and biodiesel.
The problem of fuel for vehicles, which is supposed to be a good alternative for petrol and diesel, is one of the most essential in the world. Unfortunately we are forced to seek new kinds of fuel and endure rising cost of oil and rising pollution. Several motorists have their cars run by natural gas. Someone prefers electric cars.
According to some reports in the future, about 3 million people will be left without a piece of bread and die of starvation only because of the fact that somebody wants to fill cars with new biofuels. They are made from food products such as soy, corn, sunflower, and so on. As a result, prices for these products are going to jump up quite strongly. And a lot of people in Africa and South America won’t afford to buy a simple food that will lead to lethal outcomes. This is not an exaggeration. This may be true, if humans aren’t going to stop. In spite of such gloomy prospects I’m sure that we’ll build up an environmentally friendly future.
Among many energy saving alternatives, we seriously recommend you to learn more about wood pellets.
Just a short list of advantages of using wood pellets. They are not sophisticated; they do not require huge investments into expensive “machinery”; they are ecological in the heart of it. Please invest part of your time into learning more about wood pellets - it is really important now.
