Energy Source Comparison
Energy Source Pros Cons
Hydro Power
No emissions
Reliable
Capable of generating large
amounts of power
Output can be regulated to
meet demand
Environmental impacts by changing
the environment in the dam area.
Hydroelectric dams are expensive to
build
Dams may be affected by drought
Potential for floods
Natural Gas
Widely available
Cleanest-burning fossil fuel
Often used in combination with
other fuels to decrease
pollution in electricity
generation
Made safe by adding artificial
odor so that people can easily
smell the gas in case of a leak
Transportation costs are high
Lack of infrastructure makes gas
resources unavailable from some
areas
Burns cleanly, but still has
emissions
Pipelines impact ecosystems

Energy Source Comparison
Energy Source Pros Cons
Petroleum
Efficient transportation fuel for
the world
Basis of many products, from
prescription drugs to plastics
Economical to produce
Easy to transport
High CO2 emissions
Found in limited areas
Supply may be exhausted before
natural gas/coal resources
Possible environmental impact
from drilling/transporting
Biomass
Abundant supply
Fewer emissions than fossil fuel
sources
Can be used in diesel engines
Auto engines easily convert to
run on biomass fuel
Source must be near usage to cut
transportation costs
Emits some pollution as gas/liquid
waste
Increases emissions of nitrogen
oxides, an air pollutant
Uses some fossil fuels in
conversion

Energy Source Comparison
Energy Source Pros Cons
Coal
Abundant supply
Currently inexpensive to extract
Reliable and capable of
generating large amounts of
power
Emits major greenhouse gases/acid
rain
High environmental impact from
mining and burning, although
cleaner coal-burning technology is
being developed

into electricity
Uranium reserves are abundant
Refueled yearly (unlike coal
plants that need trainloads of
coal every day)

emergency, containment,
radioactive waste, and storage
systems

Deaerator
widely used for the removal of
oxygen and other dissolved gases
from the feedwater to steam-
generating boilers. In particular,
dissolved oxygen in boiler
feedwater cause serious corrosion
damage in steam systems by
attaching to the walls of metal
piping and other metallic
equipment in forming oxides (rust)
To remove oxygen, carbon dioxide and other noncondensable
gases from feed water.
To heat the incoming makeup water and return condensate to an
optimum temperature for:
Minimizing solubility of the undesirable gases
Providing highest temperature water for injection to the boiler

Gas Turbine Power Station
Combining two or more thermodynamic cycles:
Brayton cycle and Rankine cycle, results in improved overall efficiency. It can also
work with the Otto, Diesel, and Crower cycles which may allow it to be suited to
automotive use. Aside from the Rankine cycle, the Stirling cycle could also be used

Gas Turbine Power Station
Brayton-type engine consists of three components
1. Gas compressor
2. Mixing chamber
3. An expander

Mehran University of Engineering & Technology© 2025 Department of Electrical Engineering23EL-I PGS
Gas Turbine Power Station
Advantages Disadvantages
It is simple to design & construct compared to
a Steam Power station, since no boilers are
required.
Problem of starting. Compressor needs to be
operating thus external source of power is
necessary.
Much smaller compared to Steam Power
station of same capacity
Net output is low since greater power is used
to drive compressor.
Lower operating costs Overall efficiency of plant is low ≈ 20%
because of exhaust gases still containing heat.
only efficient in a Combined cycle
configuration
Less water used since there is no need for a
condenser
Temperature of combustion chamber is too
high thus resulting in a lower life.
Maintenance charges are low .
Can be started quickly .
No stand-by losses .
