Introduction
Energy consumptions underpin every aspect of present society. The constant disruptions
of supply and increases in price have brought focus to a commodity that at some point, was
overlooked. The energy system in Australia is more diverse and intricate than before. The sector
of energy in the country contributes significantly to the nation's gross domestic product,
employment, and export earnings. A secure supply of cheap, reliable as well as environmentally
sustainable energy is indispensable to the future economic prosperity and growth of Australia.
The production and consumption of energy is a key component to poverty eradication,
economic development, improvement in the standards of living and health outcomes1. The
inadvertent impacts of energy production can lead to adverse health outcomes. Energy
production can be associated with deaths (mortality) and severe illness (morbidity) cases as
impacts of every phase of the energy production process. This might include accidents in
production and processing phases, mining of raw materials, as well as pollution effects.
Production of energy has both long-term and short-term health effects linked to air pollution and
accidents. In addition, it leads to the long-term impact of global warming. Global warming
contributes to rise in sea level, extreme weather, decrease in crop yields, reduced freshwater
resources, heatstroke which has an adverse effect on both plant and animal life2. The objective is
this paper is to look at two non-renewable sources of energy that based on the researcher analysis
are safe and cost effective. Nonrenewable energy is an energy source that will ultimately get
depleted. Examples include fossil fuels, nuclear energy, and natural gas, among many others.3
Comparison Point Nuclear Natural Gas
Cost Expensive to construct Expensive to exploit and drill
Energy Type Non Renewable (splitting or
fusing of atoms)
Non-renewable (fossil fuel)
Pollution pollute the environment less
and does not produce carbon
dioxide
Produce less carbon dioxide and is a
safer option than other fossil fuel
Efficiency 98% About 60%
Nuclear Energy
Nuclear energy is energy from the core of an atom. Nuclear energy is produced when the
atom is broken under a process known as nuclear fission4. Nuclear power plants normally use
nuclear fission with uranium atoms being the most used. During the process of nuclear fission, a
neutron collides with the atom of the uranium and splitting its, thus releasing a huge amount of
energy in the form radiation and heat5. In addition, when a Uranium atom splits, more neutrons
are produced. The produced neutrons carry on to collided with other atoms of the uranium. The
process repeatedly continues, a process described as a nuclear chain reaction.

The nuclear power plant is designed such that this nuclear chain reaction is controlled to
produce a specific amount of energy. Besides, nuclear energy can be produced in nuclear fusion
a process in which atoms are fused or combined, forming a large atom7.
The nuclear fission reaction of Uranium atom in the nuclear reactors is as indicated :

The heat energy produced form the process through a heat exchange system is used to
boil water to produce steam. The steam thus drive a turbine as well as electrical generators in the
power plant8. The Uranium is split into bromine and lanthanum nuclei releasing more neutrons.

Uranium split into lanthanum and molybdenum and two neutrons to continue the chain.
In the
As fission of a uranium nuclear takes a neutron while producing two or three neutrons,
fission of a single nuclear can trigger two or three further fissions and the process repeats. If the
process is left uncontrolled, the amount of energy being release can increase rapidly to a very
dangerous level9. This avoided in the nuclear plant by ensuring that uranium-235 concentration
in the fuel is not that much high to result in an explosion and the chain reaction carefully
controlled thus ensuring stable and steady energy production10. The chain reaction and ultimate
energy released is controlled by inserting neutron-absorbing control rods into the reactor to
absorb an excess neutron. Lowering control rods deeper into the reactor would result in fewer
neutrons available for the chain reaction. The control rods are raised to increase the power
output.11
