Energy is something that
all living things depend upon. “Plants use flows of energy from the sun to make
food. Humans use food to power their bodies and a variety of other sources to
carry on complex activities in the modern world”. (Robertson, p. 158). Today most energy is produced from fossil
fuels, a nonrenewable resource. However we do have renewable resources on earth
such as wind and sunlight, which are being constantly replenished. That’s the
problem with fossil fuels are replenished but take hundreds of millions of
years, which for humans sake is never.

There are three main fossil
fuels, oil, natural gas, and coal. Oil
is a combination of hundreds of complex hydrocarbon molecules that have
fossilized over hundreds of millions of years. Drilling for oil is extremely
complex and takes up to six different exploratory drills to find a oil depository.
This extraction process is extremely time consuming and generates waste
drilling fluid called “drill mud” (Robertson, P. 159). Over the years land
based fields have become depleted so oil companies are turning to drilling in
the ocean.
The petroleum that is extracted from the ground is not ready to be
used it must be refined. The Petroleum must be boiled and distilled in to
different grades of fuel used in various industries. Like everything else in
life, it is good in moderation, same rules applies to oil. If we used it in
moderation and did not rely on it to the extent we do today the world would be
a much better place. If oil reserve rain dry today, the western world would go
into panic. Gas would sky rocket in price because there was no more supply and people
would need to change the way they function in todays society. A saying my
grandmother always says, “it is the way it is, because you set it up that way”.
This is true for oil. We rely on it to much.

We as a country and
people group need to start looking into more renewable energy sources, such as
wind and solar. The nice thing about these sources is, they are free and they
are not going anywhere anytime soon. To produce energy, mechanical energy is
used to turn a generator. “A generator is a device that converts mechanical
energy into electrical energy”. (Robertson, P. 164). For example, wing can turn
fan blades that then turn the generator to create electricity. Another sources
of renewable energy is hydroelectrically power. A great example is Niagara
Falls. The amount of kinetic energy the falls creates with the millions of
gallons of water that fall each and everyday is incredible. By placing some turbines
near the falls, the current the water moves at will create an astounding amount
of clean renewable energy.
