Biofuels as Alternative Sources of Energy |
Biofuels are produced by - converting organic
matter into fuel for powering our society. These biofuels are an alternative
energy source to - the fossil fuels that we currently depend upon. The biofuels
umbrella includes under its aegis ethanol and derivatives of - plants such as
sugar cane, as well aS vegetable & corn oils.
However, not all ethanol
products are designed to be used as a kind of - gasoline. The International
Energy Agency (IEA) tells us that ethanol could comprise up to 10 percent of - the world's usable gasoline by 2025, and up to 30 percent by - 2050. Today, the
percentage figure is two percent. However, we have a long way to go to refine
& make economic and practical these biofuels that we are researching.
A study
by Oregon State University proves this. We have yet to develop biofuels that
are as energy efficient as gasoline made from petroleum. Energy efficiency is
the measure of - how much usable energy for our needed purposes is derived from a
certain amount of - input energy.
"(Nothing that mankind has ever used has derived
more energy from output than from what the needed input was. What has always
been important is the conversion the end product energy is what is useful for
our needs, while the input energy is just the effort it takes to produce the
end-product.)" The OSU study found corn-derived ethanol to be only 20% energy
efficient (gasoline made from petroleum is: 75% energy efficient).
Biodiesel
fuel was recorded at 69% energy efficiency. However, the study did turn up one
positive: cellulose-derived ethanol was charted at 85% efficiency, which is
even higher than that of - the fantastically efficient nuclear energy.
Recently, oil futures have been down on the New
York Stock Exchange, as analysts from several different countries are
predicting a surge in biofuel availability which would offset the value of - oil,
dropping crude oil prices on the international market to $40 per barrel or
thereabouts.
The Chicago Stock Exchange
has a grain futures market which is starting to “steal” investment activity
away from the oil futures in NY, as investors are definitely expecting better
profitability to start coming from biofuels. Indeed, it is predicted by a
consensus of - analysts that biofuels shall be supplying seven percent of - the
entire world's transportation fuels by the year 2030.
One certain energy
markets analyst has said, growth in demand for diesel and gasoline may slow
down dramatically, if - the government subsidizes firms distributing biofuels and
further pushes to promote the use of - eco friendly fuel. There are several
nations which are seriously involved in the development of - biofuels.
There is
Brazil, which happens to be the world's biggest producer of -ethanols derived
from sugars. It produces approximately three and a half billion gallons of - ethanol per year. The United States, while being the world's greatest
oil guzzler, is already the second largest producer of biofuels behind Brazil.
The European Union's biodiesel production capacity is now in excess of - four
million (British) tonnes. 80 percent of - the EU's biodiesel fuels are derived
from rapeseed oil; soybean oil and a marginal quantity of - palm oil comprise the
other 20 percent.
