2.1Nuclear Energy and other
energy sources

2.1.1 Nuclear Energy versus Fossil Fuel Energy

the comparison between nuclear and fossil fuel power plants find out they have
same working principle which state convert potential thermal energy into
mechanical rotation with difference type of used fuel that generate heat to
produce steam that drive Steam Generator to afford electricity. Every day the world
oil reserves shrink and in future will be unavailable. The thermal energy supplies
in fossil fuel plants come from burned oil, natural gas, coal to obtain
necessary thermal energy.

        The fundamental difference between the nuclear
and fossil fuel station in terms of financial cost is running and maintenance
costs. The running cost in fossil fuel station is higher than nuclear station.

In order to be produced 1(GW) coal-fired power plant is needed 9000 TON of fuel
per day while a nuclear plant consumes about 3(kg)
of uranium in the same production and time.    

        The waste burned fossil fuel constitute
the largest danger facing humanity after combustion fossil fuel yields CO2
“carboxyl”  which is one of the causes of
global warming. In addition combustion remnants have negative effects on the
environment such as (methane, Sulphur dioxide,
nitrous oxides, and other pollutants). 
The nuclear power plant is considered to be somewhat eco-friendly in
terms of there are not gaseous emissions.


2.1.2 Nuclear Energy versus Hydroelectric Energy

       The hydroelectric energy is very effective,
economic, clean no gaseous emission. This technology utilize in areas rich in
river water by take advantages flow rate of rivers they are stored in huge dams
and then avail the sum of energies for river (kinetic energy, potential energy,
and internal energy )  so as to rotate
turbines to generate electricity.

 Bernoulli’s equation
express all sum of   kinetic
energy, potential energy, and internal energy must be constant at same along a
streamline. Implying with increase fluid speed will be caused increasing in
both dynamic pressure and kinetic energy occur when the sum of energies are reduced
at simultaneous.

      Although the hydroelectric stations have
advantages but also it adversely impact on the surrounding environment the
major problem oppose this technology the nature of the river is unstable
implying there are dry seasons that  may
cause the station is stopped or operate with low efficiency. In addition, the
hydroelectric stations have certain risks related by construction and operation
including foundation problems and
environmental damage for areas flooded and downstream.


2.1.3 Nuclear Energy versus
Wind Energy

              Wind turbine is
one of the common renewable energy, the wind energy is modern technology it can
be high efficiently, which provide energy from natural sources, without
environmental impact. It does not causes greenhouse gases. At it’s operate on a
simple principle. The energy in the wind turns two or three turbine’s blades around
a rotor. The rotor is connected to the main shaft (drive shaft), which spin a
drive shaft connected to a gearbox with driven shaft to increase the rotation
of generator that makes electricity large. Simply, a wind turbine works the
opposite of a fan. It has an instrument on the top of the nacelle, an
anemometer and a wind vane, which measure wind speed and direction. When the
wind changes direction, motors turn the nacelle, and the blades along with it,
around to focus into the wind to ensure that the optimum amount of power is
extracted from the wind, this means that the wind is not constant, therefore,
it don’t produce the same amount of electricity all the time. In addition, its noisy
Wind turbines, can convert the kinetic energy in the wind into mechanical
power. This mechanical power can converted into electrical energy using
generator to produce electricity. Turbines are grouped together to form of
a wind power plant, where as large spaces of land use.
