Why Biofuels Are A Sustainable Solution
Category: softwareAs people have started looking towards alternative energy sources, bio-fuels have often come up as a solution. So what exactly are bio-fuels? How do they differ from fossil fuels? How are they produced? And are they a sustainable solution to the world’s energy crisis?
As the name implies, biofuels are fuels derived
from organic material. Since they can be made in many ways, they are
classified as 1st generation, 2nd generation, and 3rd generation.
First generation bio-fuels
are the more common fuels that are produced from food crops and animal
fats. Some examples include bio-diesel, vegetable oil, and bio-gas.
Second generation bio-fuels
are made from waste biomass, making them a more sustainable solution as
compared to their 1st gen counterparts. They include various alcohols
(such as ethanol) and diesel derived from wood and even human excrement.
Third generation bio-fuels
are generally made from algae that are farmed on a massive scale. By
way of photosynthesis and the breaking down of carbon dioxide, the
carbohydrates extracted from these micro-organisms is used to make
various fuels.
So what separates bio-fuels from fossil fuels?
Bio-fuels differ from fossil fuels in the following ways:
pollution from fossil fuels is far more severe. Although burning
bio-fuels also creates emissions, the carbon dioxide is more
environmentally friendly and absorbed easily by crops and organisms.
fuels are non-renewable, whereas bio-fuels tend be more renewable. As
long as there is human excrement, there will be bio-fuels.
Furthermore, with the help of crop rotation, there can be an endless
supply of bio-fuels.
This leads us on to the advantages of bio-fuels:
- As more people use bio-fuels, it lowers the demand on pollution creating fossil-fuels.
- This helps reduce harmful carbon emissions, making bio-fuels more friendly for the environment.
- And since they can be made from almost any organic substance, bio-fuels are a cheap alternative for consumers.
Bio-fuels sound too good to be true. There must be some disadvantages to producing and using them. So, are there any?
Like any new technology, of course there are disadvantages
Although
they are environmentally friendly, bio-fuels have been ironically
criticized by the environmental community, for the reasons given below:
- It
has long been debated on the usefulness on first generation bio-fuels
as compared to the shortage of food they could cause. Producing
bio-fuels from crops make the food worthless for us to eat. And some
people believe that we should rather use those crops to cure world
hunger than to power our vehicles and homes. - The large
farmlands necessary to produce first and third generation bio-fuels can
result in us encroaching on the natural ecology of plants and animals.
So you can see, biofuels are still a contentious issue. However , we
believe that with the correct management - such as crop rotation - and
improved technology biofuels can be a sustainable solution that will do more good than harm. But only time will tell.
