Change
to Renewable Energy for a Better Life
Do you know when will
oil reserves run out? Do you know about the dangerous nuclear energy? According
to the calculation, the world’s oil will be out within 44 years. Moreover,
nuclear energy is very dangerous. You can look at accident in Chernobyl. Now, Chernobyl
is like a dead city. Looking at the amount of oil and the danger from nuclear,
we must save our oil with minimum using. We must use renewable energy. Now, using renewable energy is
important because it can reduce oil consumption, unlimited and
eco-friendly.
Oil
reserve is unlimited but the consumption increase as much as
increase of human on our earth.
According to data from CIA website, sum of oil reserve in the earth is
1,349,417,153,000 barrels. In addition, country that has biggest oil
reserve is Arab Saudi with 262,700,000,000 barrels. According
to data from the same source, world oil consumption is 82,769,370.4 bbl/day.
When we calculate the data, we know that our oil will be out about 44 years
again. It will happen if the consumption is same with now. However, we know
that every year the demand of oil is increasing. Therefore, the oil will be out
before 44 years if we do not do something. “First, organic matter has to be
synthesized by living organisms and thereafter it must be deposited and preserved
in sediments. Depending on further geological events, part of sedimentary
organic matter may be transformed in to petroleum-like compounds” (Tissot &
Welte, 1984, p. 3).What is organic matter? The body of animal or plant lived
before us. From the organic matter to be petroleum, it needs hundreds of
thousand years. That is why, petroleum quickly used
up, petroleum is quick in consuming while forming process need much time.
Source of renewable
energy is unlimited because the source can continuously use or the sources are
unlimited as the sunlight .Kind of renewable energy is hydro-energy
(hydropower), wind power, geothermal energy, solar energy, and biofuel.
Hydropower is the first renewable energy we use for power plants. Geothermal
energy is used in power plants. The heat from the magma in our earth boils the
water, which injected and made the water become air that turns the turbine to
produce electricity. ”Every kilowatt of geothermal base load power, is capable
of saving about two tons of oil fuel per annum” (Christopher & Armstead,
1983, p. xxxiii) .Because the difference of sun light that the earth receive,
there are winds. “If all the potential sites for mills were exploited, wind
might supply as much as one-third of the current energy demand in the world”
(Katzman, 1984, p. 12). Solar energy systems use radiation from the sun to
produce heat and electricity. There are three basic categories of solar energy
systems: Solar Thermal Systems, Solar
Thermal-Electric Power Plants and Photovoltaic Systems.
Solar thermal systems and solar thermal-electric power plants use
to heat the water. Then the hot water can use in house or heat again until
became air to turn the generator in power plan. However, in photovoltaic systems, the radiation from the sun directly
converts to electric with the cells in the PV panel. Biofuel is made from corn
or crude palm oil. Therefore, if we have corn or CPO we can make bio fuel.
Biofuel is better than oil, because when we burn biofuel, it produce less of
carbon dioxide. Now, just 18% from world energy that using renewable energy,
(Renewables Global Status Report 2011, p. 79) is not enough. We must increase
the ratio energy quickly before our oil run out.
Renewable energy is more eco-friendly than
alternative energy like nuclear. Nuclear energy can be used to substitute oil
and gas in power plants to decrease their consumption. Price of electricity
with nuclear is cheapest than other source energy. We just need a little
plutonium to electricity a town in a day. Technology in nuclear power plant is
more advanced than others. It is the advantages of nuclear energy. However, we
have a big problem with nuclear. Nuclear is like knife. It is useful when we
use it as power plants but nuclear is very dangerous when it is used as weapon.
It is more dangerous than “little boy” and “fat man“in the world war II. When
we use nuclear as power plants, there are also danger. Although we have
high-technology security, there are also risks. If the reactor leaks, the
radiation will blow up and spread out, following the wind. The radiation
nuclear can make evolution, cancer and other disease. We can also in risk when
disaster like earthquake or mountain eruption makes damage to reactor. Both of
them are risk in accidents risk, but there is another risk. It is sabotage and
blackmailing. The terrorist may sabotage the nuclear facility to terror the
people. They can release the radioactive material, destruction of facilities
and explosive device. Example of dangerous of nuclear is in Chernobyl and in
Three Miles Island. In Chernobyl, there is a nuclear reactor, because there is
a problem, the reactor burst. It has broken the shield, so the nuclear
radiation spread out around the city. Radiation in Chernobyl spread out until
Scandinavia. All of the people evacuated to another city. Now, Chernobyl like
dead city. There are no live, even a plant. In Three Miles Island, 1979 there
was accident that made the reactor broken. Fortunately, the shield in reactor
was not broken. Therefore, just little radiation spread out to the air.
(Rinaldy, 1999, p. 13).
“Throughout 1950s-1960s engineers sought to improve
efficiency simply by making power station units lager” (Patterson, 1990, p.
119). Now, we cannot do like that again. Because the petroleum, the source of
our energy is limited and it is not eco-friendly. Therefore, we must substitute
the source of our energy. Currently we have to use renewable energy because it
is more eco-friendly than other energy and help us to have a better life.
