(Author's note: This is my science piece on energy from algae)
Algae
are commonly referred to as pond scum. People don’t think much of it. Algae are plants that contain a high amount
of natural oil. Researchers today are finding out that they can make biodiesel
fuel from this oil, and that algae is one of the fastest growing plants on
earth. It is being called “The ultimate in renewable energy” (Algae: ‘The
ultimate in renewable energy’, 2008). Being able to make a lot of oil in a short
amount of time gives algae the potential to surpass crude oil and become one of
the world’s largest energy producers.
One
of the best things about algae oil is that it is a very practical energy
source. It is clean, so it won’t contribute to global warming. Algae are also
very versatile; we can grow it almost anywhere in the world. It can be grown in almost any pond, but "A pond has a limited amount of surface area for solar absorption," (Algae: 'The ultimate in renewable energy', 2008). Algae oil is grown in vertical chambers for optimum solar absorption, so it not found, therefore it is a renewable resource. Algae oil is one of the few
energy sources that is both clean, and efficient.
Energy
production isn’t the only use for algae. It can be used in a variety of ways.
Algae are a food for many types of fish, but humans can eat it too. It is used
commercially in many health care products. Algae also are a natural filter, so
it is used to clean polluted bodies of water. Algae can get stop pollutants
being used, and clean up the damage they already have done.
It
seems that algae oil is the perfect clean energy source, but right now it has
one major flaw, it is very expensive. While you may think four dollars a gallon
for gas is through the roof, algae oil costs about thirty dollars a gallon.
Algae can grow anywhere, but the problem is harvesting it. Scientists haven’t
yet found a way to do this cheap and efficiently. However, scientists project
that they will keep coming up with technology to help with this problem. It
will take another five to ten years until we can actually use algae oil as an
energy source practically, but once we get around this problem, algae oil will
be used as a very viable resource.
Algae
oil is a great idea and should defiantly be invested in. With all the big oil
companies harming the environment, we need a source of clean energy that is
reliable and practical. I think algae oil will be the answer or at least a key
piece to solving the energy crisis. We may not use it now, but when the
technology comes out; I believe algae will become one of the top energy
sources.
