Bio-Fuels
As the expression suggests, bio-fuels are fuels that are made when organic stuff
decomposes.
Mostly created from plants, bio-fuels occur in all three states of
matter: solid, liquid, and gas.
Variation between bio-fuels and fossil fuels
Bio-fuels are different from fossil fuels in the following ways:
- Bio-fuels can be produced incredibly fast in few days, whereas fossil fuels
take a million years to be made.
- Bio-fuels are moderately safer, but fossil fuels result in enormous amounts
of smog.
- Bio-fuels are a renewable source of energy as opposed to fossil fuels.
Different kinds of bio-fuels:
Bio-fuels have been categorized into four varieties: first generation, second
generation, third generation, and fourth generation.
The first generation bio-fuels are derived from sugar, starch, and vegetable fats,
that are in turn manufactured from crops. First generation fuels are also made
from animal fat. Examples of this type of bio-fuel are cooking oil, bio-diesel, and biogas.
The second generation of bio-fuels is essentially derived from waste biomass,
therefore making it a better choice compared to the first-generation bio-fuels.
Different varieties of alcohols and diesel resultant from wood fall into the kind of
second generation bio-fuels. A good example would be ethanol produced from
corn.
The third generation covers bio-fuels derived from algae. Algae are farmed on a
big scale for producing these bio-fuels. The algae fuels are especially
environmentally friendly seeing that they can effortlessly decompose into the soil
without damaging it.
The bio-fuels in the fourth generation are created by a way in which bacteria are
brought to work with carbon dioxide to produce fuel.
Advantages of bio-fuels:
Bio-fuels are valuable in the following ways:
- Bio-fuels, especially bio-diesel, show to be exceptionally cost-effective for
consumers.
- They decrease the load on progressively-decreasing fossil fuels.
- They are environmentally friendly since they help lower carbon pollution in the
environment.
Drawbacks of bio-fuels:
Bio-fuels are not without criticism.
Though good for the atmosphere, bio-fuels have their disadvantages, oddly enough
in the green purview. Bio-fuels have acknowledged condemnation for loads of
explanations, several of which are explained below:
- Making bio-fuels involves large tracts of farming land, as a result intruding upon
the natural environment of plant life and animals.
- Economists have long disputed the helpfulness of first generation bio-fuels when
weighed against the lack of food they create. Producing fuel from food yields
makes them unworthy of human consumption.
Some of us think that being a superior concern than fuel, food should not be
farmed for manufacturing fuels but for human eating.
Final Thought:
Although bio-fuels are an excellent sustainable source of energy, the way some of
them are produced can be detremental to plant, animal and even human life.
While bio-fuels definitely play a part in The Future Of Electricity, they more are
practical to employ for people living on farms where the ingredients are readily
available, as opposed to living in the city.
Perhaps a better source of renewable electricity for people living in the city, is
the use of home solar power and wind power systems at home. These solutions
have been rather popular of late, as can be seen at DIY-Renewable-Energy.com.
