“What does ‘LOL’ stand for in Pakistan?
‘Lots-of-Loadshedding’.”
“Why isn’t anyone intervening in Africa (as in
Middle East)? It’s the layer of oil on Middle East … otherwise it’d have been
no different than Africa.”

Energy makes change; it does
things for us. It moves cars along the road and boats over the water. It bakes
a cake in the oven and keeps ice frozen in the freezer. It plays our favorite
songs and lights our homes. Energy makes our bodies grow and allows our minds
to think. Scientists define energy as the ability to do work.
FORMS OF ENERGY:
Energy is found in different forms, such as light, heat, sound,
and motion. There are many forms of energy, but they can all be put into
two categories: potential and kinetic.
POTENTIAL
ENERGY:
Potential energy is stored energy and the energy of
position, or gravitational potential energy. There are several forms of
potential energy.
· CHEMICAL ENERGY is energy stored in the bonds of atoms
and molecules. It is the energy that holds these particles together. Biomass,
petroleum, natural gas, propane, and the foods we eat are examples of stored
chemical energy.
· ELASTIC ENERGY is energy stored in objects by the
application of a force. Compressed springs and stretched rubber bands are
examples of elastic energy.
· NUCLEAR ENERGY is energy stored in the nucleus of an
atom; it is the energy that holds the nucleus together. The energy can be
released when the nuclei are combined or split apart. Nuclear power plants
split the nuclei of uranium atoms in a process called fission. The sun combines
the nuclei of hydrogen atoms in a process called fusion.
· GRAVITATIONAL POTENTIAL ENERGY is
the energy of position or place. A rock resting at the top of a hill contains
gravitational potential energy because of its position. Hydro-power, such as
water in a reservoir behind a dam, is an example of gravitational potential
energy.
KINETIC ENERGY:
Kinetic energy is motion; it is the motion of
waves, electrons, atoms, molecules, substances, and objects. Electrical energy
is the movement of electrons. Everything is made of tiny particles called
atoms. Atoms are made of even smaller particles called electrons, protons, and
neutrons. Applying a force can make some of the electrons move. Electrons
moving through a wire are called electricity. Lightning is another example of
electrical energy. Radiant energy is electromagnetic energy that travels in
vertical (transverse) waves. Radiant energy includes visible light, x-rays,
gamma rays, and radio waves. Solar energy is an example of radiant energy.
THERMAL ENERGY:
Thermal energy, or heat, is the internal
energy in substances; it is the vibration and movement of the atoms and
molecules within a substance. The more thermal energy in a substance, the
faster the atoms and molecules vibrate and move. Geothermal energy is an
example of thermal energy.
MOTION ENERGY:
Motion energy is the movement of objects
and substances from one place to another. Objects and substances move when an
unbalanced force is applied according to Newton’s Laws of Motion. Wind is an
example of motion energy. Sound energy is the movement of energy through
substances in longitudinal (compression/rarefaction) waves. Sound is produced
when a force causes an object or substance to vibrate; the energy is
transferred.

INTRODUCTION TO ENERGY:
Energy is considered
to be life line of any economy and most vital instrument of socioeconomic
development of a country. Energy is pivotal in running machinery in factories
and industrial units, for lighting our cities and powering our vehicles
etc. There has been an enormous increase in the demand of energy as a
result of industrial development and population growth, in comparison to
enhancement in energy production. Supply of energy is, therefore, far less than
the actual demand, resultantly crisis has emerged. An energy crisis can be
defined as any great bottleneck (or price rise) in the supply of energy
resources to an economy.
Thermal energy,
or heat, is the internal energy in substances; it is the vibration and movement
of the atoms and molecules within a substance. The more thermal energy in a
substance, the faster the atoms and molecules vibrate and move. Geothermal
energy is an example of thermal energy. Motion energy is the movement of
objects and substances from one place to another. Objects and substances move
when an unbalanced force is applied according to Newton’s Laws of Motion. Wind
is an example of motion energy. Sound energy is the movement of energy through
substances in longitudinal (compression/rarefaction) waves. Sound is produced
when a force causes an object or substance to vibrate; the energy is
transferred.
CONSERVATION OF ENERGY:
Your parents may tell you to conserve energy. “Turn off the lights,” they say.
To scientists, energy conservation is not just about saving energy. The Law of
Conservation of Energy says that energy is neither created nor destroyed. When
we use energy, it doesn’t disappear. We change one form of energy into another.
A car engine burns gasoline, converting the chemical energy in gasoline into
motion energy. Solar cells change radiant energy into electrical energy. Energy
changes form, but the total amount of energy in the universe stays the
same.
HISTORY:
· 1960's:
A large civilian
energy input and infrastructure was built by the Pakistan military, with
the financial funds provided by various countries and international monetary
sources.
Much of the energy was
produced by the hydroelectric dams and thermal power
stations.
· 1970's:
In the 1970s, Pakistan's energy consumption
expanded to nuclear power sources with the establishment and
commissioning of first nuclear power station in Karachi. Highest oil
production in major industrial nations (Germany, United
States, Canada, etc.)
· 1973:
Oil crisis
· 1980's:
The dependence on
nuclear sources further grew and the military continued engineering
and building the nuclear power infrastructure.
· 1994:
Prime Minister Benazir Bhutto of Pakistan People’s
Party (PPP) launched the country's
Out of the total installed capacity of 11000MW, 60% of energy was produced from
the hydroelectric power sources.
· 1995:
Only 27 IPPs were able
to generate 6,335MW of electricity.
· 2001:
The military government led
by President Pervez Musharraf and Prime
Minister Shaukat Aziz, while contributing to the growth of domestic demand
for electricity through large-scale provision of bank loans for the purchase of
air-conditioners and home appliances (share of domestic energy consumption had
jumped to 46% of the total by 2008)
· 2008:
After the general
elections the mismanagement and weak policies increased the cycle of load
shedding in the country.
- Prime
Minister, Yousaf Gilani announced the "energy policy" on 22
April 2010
-Musadik Malik has been entrusted to develop Energy Policy for Pakistan.
He was appointed Federal Minister, Water and Power of the Pakistan Government
in 2013.
PAKISTAN'S ENERGY SECTOR:
Pakistan’s energy infrastructure is not well developed, rather
it is considered to be underdeveloped and poorly managed. Currently the country
is facing severe energy crisis. Despite of strong economic growth and rising
energy demand during past decade, no serious efforts have been made to install
new capacity of generation. Moreover, rapid demand growth, transmission losses
due to outdated infrastructure, power theft, and seasonal reductions in the
availability of hydro power have worsened the situation. Consequently, the
demand exceeds supply and hence load-shedding is a common phenomenon through
power shutdown.
ENERGY SUPPLY:
During 2009-10, Energy supply and per capita availability of
energy witnessed a decline of 0.64 % and 3.09 % respectively in comparison to
previous year.
Pakistan needs around
15,000 to 20000 MW electricity per day, however, currently it is able to
produce about 11,500 MW per day hence there is a shortfall of about 4000 to
9000 MW per day. This shortage is badly hampering the economic growth of the
country.
ENERGY CONSUMPTION:
Pakistan’s energy consumption is met by mix of
gas, oil, electricity, and coal and LPG sources with different level of shares.
Share of gas consumption stood at 43.7 %, followed by oil 29.0 percent,
electricity 15.3 percent, coal 10.4 percent and LPG 1.5 percent.
SOURCES OF ENERGY IN PAKISTAN:
Non-renewable resources (Fossil fuels): [Limited – Expensive]
Nonrenewable
resources are primarily fossil fuels emanating from remains/decomposition of
animals and plants deposited deep into the earth crust and converted into oil
and gas. These resources cannot be replenished. There are three main types of
fossil fuels: coal, petroleum, natural gas and liquefied petroleum gas (LPG).
PETROLEUM PRODUCTS:
NATURAL GAS:
Importance of natural gas is increasing
rapidly. Average production of natural gas is 4,048.76 million cubic feet per
day as against 3,986.53 million during corresponding last year, showing an
increase of 1.56 percent. Natural gas is used in general industry to prepare
consumer items, to produce cement, for manufacturing fertilizers and to
generate electricity. In form of CNG, it is used in transport sector. Share of
natural gas in energy consumption is 43.7 percent. Due to price differential
between CNG and Petrol, vehicles are using converted to CNG and approximately
2.0 million vehicles are using CNG and currently Pakistan is the largest CNG
user country in the world. Liquefied petroleum gas (LPG) contributes around 0.7
percent to total energy supply in country and is being imported to stop
deforestation in hilly areas.
COAL:
Pakistan has coal reserves estimated at over 185 billion metric tons, including 175 billion metric tons identified at Thar coalfields. Coal is primarily being used in brick kiln and cement industries and approximately 67 percent coal is imported because indigenous coal is not considered of good quality.
Guddu plant is largest plant thermal operated plant with a capacity of 1,650 MW, while two largest Independent Power Plants (IPPs) in Pakistan are Kot Addu (1,600 MW) and Hubb River (1,300 MW).
RENEWABLE RESOURCES: (Unlimited –
sustainable – clean)
Renewable
energy resources are those, which are naturally replenished and come from
resources such as water, sunlight, wind, rain, tides, and geothermal heat.
HYDRO POWER:
Hydro power is generated by using electricity
generators to extract energy from moving water. Pakistan is having rich
resource of energy in hydal power, however, only 34 % of total electricity
generation is coming from hydro power. Currently we are having 6555 MW against
the potential of 41000 to 45000 MW.
CURRENT HYDRO POWER STATIONS:
Tarbella Dam : 3,478 MW
Ghazi Brotha: 1450 MW
Mangla 1,000 MW
Warsak 240 MW
Chashma 184 MW
POTENTIAL HYDRO POWER
STATIONS:
Diamer-Bhasha Dam 4500 MW
Munda Dam – Swat river in Mohamand Agency 740
MW
Kalabagh Dam 2400-3600 MW
Bunji Dam 5400 MW
Dasu Dam 3800 MW
Wind:
Wind power harnesses the power of the wind to propel the blades of wind turbines. These turbines cause the rotation of magnets, which creates electricity. Though Pakistan has potentials of wind energy ranging from 10000 MW to 50000 MW, yet power generation through wind is in initial stages in Pakistan and currently 06 MW has been installed in first phase in Jhampir through a Turkish company and 50 MW will be installed shortly. More wind power plants will be built in Jhampir, Gharo, Keti Bandar and Bin Qasim Karachi.
Solar:
Solar power involves using solar cells to convert sunlight into
electricity, using sunlight hitting solar thermal panels to convert sunlight to
heat water or air. Pakistan has potential of more than 100,000 MW from solar
energy. Building of solar power plants is underway in Kashmir, Punjab, Sindh
and Balochistan. However, private vendors are importing panels / solar water
heaters for consumption in the market.
Alternative Energy
Development Board (AEDB) is working for 20,000 solar water heaters in Gilgit
Baltistan. Mobile companies have been asked by the government to shift supply
of energy to their transmission towers from petroleum to solar energy panels.
Agricultural biomass /biodiesel:
Biomass production involves using garbage or other renewable
resources such as sugarcane, corn or other vegetation to generate electricity.
When garbage decomposes, methane is produced and captured in pipes and later
burned to produce electricity. Vegetation and wood can be burned directly to
generate energy, like fossil fuels, or processed to form alcohols. Brazil has
one of the largest renewable energy programs from biomass/biodiesel in the
world, followed by USA. Alternative Energy Development Board (AEDB) of Pakistan
has planned to generate 10 MW of electricity from municipal waste in Karachi
followed by similar projects in twenty cities of country.
Tidal:
Tidal power can be extracted from Moon-gravity-powered tides by
locating a water turbine in a tidal current. The turbine can turn an electrical
generator, or a gas compressor, that can then store energy until needed.
Coastal tides are a source of clean, free, renewable, and sustainable energy.
Plans are underway in Pakistan to harness tidal energy; however, no
implementation has been made so far.
Nuclear:
Nuclear power stations use nuclear fission reaction to generate
energy by the reaction of uranium inside a nuclear reactor. Pakistan has a
small nuclear power program, with 425 MW capacity, but there are plans to
increase this capacity substantially.
Since Pakistan is outside the Nuclear Non-Proliferation Treaty, it is excluded
from trade in nuclear plant or materials, which hinders its development of
civil nuclear energy. Remaining issues in development of nuclear energy are
enrichment of uranium from U235 to U238, controlling chain reaction and dumping
of solid waste.

CRISIS IN PAKISTAN:
· Increasing in population
· High Prices
- Especially increasing in oil prices since 2003
· Industrial sector
- Faisalabad industrial zone
- Industries shifting to abroad
· Growing GDP and Energy requirement
- Double in 2015
- 7 times by 2030
· Gap between Demand and Supply
- Energy supply per capita in 2012 decline 3.09%
· Over consumption
· Infrastructure damage
· · Misuse of electricity and water
CAUSES OF ENERGY CRISIS:
Pakistan’s
energy crisis traces its roots to following distinct causes:
Over the years there
is greater need of energy because of;
· Increase in
population
· Enhancement in lifestyle
· Industrial and
agricultural growth
· Greater
transportation needs
Lack of proactive and integrated planning for
production of energy:
Pakistan has had wider potentials to tap energy, however, due to
lack of any integrated/proactive planning, very less number of power producing
plant were installed to meet futuristic demands. Resultantly, over the years,
the gap between energy demand and supply drastically grew and now against
demand of 20000 MW, we are having around 11500 MW.
Imbalance energy mix:
Energy mix in Pakistan is quite imbalance in comparison to other
countries, with greater reliance on non-renewable resources of gas (43.7 %) and
oil (29 % - majority of which is imported). Prices of petroleum products/crude
oil fluctuate and in current Afro-Arab political crisis, the oil prices are
likely to increase manifold affecting oil prices in Pakistan.
A rational energy mix planning ought to be developed giving greater dependency
to renewable (hydel power), indigenous (coal) and alternative energy resources
(wind and solar energy).
Non-utilization of
enormous indigenous energy resources:
Thar Coal:
· Pakistan is having one of the largest coal
fields in Thar, having reserves of more than 175 billion tones, which exceeds
equivalent oil reserves of Saudi Arabia, Iran etc.
· In addition to power generation, and this coal
can be used for chemical and fertilizer production.
· Moreover, employment provided to workforce can
be instrumental in increasing GDP and economic prosperity to many
families.
Hydal power generation:
· Pakistan has potential of hydro resources to
generate 41000 to 45000 MW, however, only 6555 MW is currently being generated
by this important renewable resource.
· Four large hydropower dams namely Kalabagh
3600 MW, Bhasha 4500 MW, Bunji 5400 MW and Dasu 3800 MW can be constructed to
generate hydroelectricity.
· Similarly, many small to medium hydro plants
can be installed on rivers and canals etc.
CONSEQUENCES OF ENERGY CRISIS:
Economic Factors:
Energy is pivotal for running all other
resources and crisis of energy directly influences all other sectors of the
economy. The economic progress is hampered by decline in agricultural
productivity as well as by halting in operations of industries. One important
factor of lower GDP and inflation of commodity prices in recent years is
attributed to shortfalls in energy supply.
Agriculture Sector:
Agricultural productivity of Pakistan is decreasing due to
provision of energy for running tube wells, agricultural machinery and
production of fertilizers and pesticides. Thus higher energy means higher
agricultural productivity.
Industrial Sector:
Nearly all Industrial
units are run with the energy and breakage in energy supply is having dire
consequences on industrial growth. As a result of decline in energy supply,
industrial units are not only being opened, but also the existing industrial
units are gradually closing.
Unemployment:
By closure of industrial units and less
agricultural productivity, new employment opportunities ceased to exist and
already employed manpower is shredded by the employers to increase their profit
ratios. Thus energy crisis contributes towards unemployment.
Social Issues:
This factor is primarily related to the domestic usage of
energy (cooking, heating and water provision). Load shedding cause unrest and
frustration amongst the people and results in agitation against the government.
Poverty:
Declination in economic growth, lower
agricultural productivity, unemployment and shackling industrial growth result
in increasing poverty. Currently, around forty percent of our population is living
beyond poverty line and this ratio is increasing day by day.
CONSERVATION AND CONSUMPTION:
Due to rising demand and a failing power infrastructure severe electricity
shortages have occurred in Pakistan. Power outages can last 6–8 hours
a day in the cities and many more in the rural areas.
· Children can't do their homework.
· Housework doesn't get done, as washing
machines and other appliances cannot work.
· When you go home from work, you have no idea
whether there will be electricity at home. Your whole life is
disturbed.
IMPACT OF ENERGY CRISIS:
- 5-7 hours of electricity
outage effect on Student’s studies.
· Effect on Industrial Sector
-Minimum supply of Energy resource to Industries leads minimum Production.
· Higher Electricity Price
- Consumer to pay high price of electricity due to insufficient
supply and high cost of electricity production
· Effect on Economy
-Minimum Supply of Energy into an economic will lead to less
economy activity as whole production of country will not be as per its
capacity.
RESOLVING PAKISTAN'S ENERGY CRISIS:
The previous government, led by President Asif
Zardari, did take some steps to reduce the supply-demand gap through
implementing consumer friendly energy policies. A mega corruption scandal
involving high-level officials eventually got taken up by the National
Accountability Bureau (NAB), which reported massive losses to the
government. These corrupt practices increased the gap in supply and demand of
the total output supplied via Distribution Companies (DISCOs) and National
Transmission and Dispatch Company (NTDC).
Subsequently, when
the government of Prime Minister Nawaz Sharif took over in June 2013, the
energy shortfall was already at dangerous levels with overall supply deficit
reaching 6000MW to 7000MW during the summers. Prime Minister Nawaz Sharif and
his team took few steps to reduce load shedding by implementing shortfall
reduction policies for commercial and residential areas. Furthermore, six
coal-based power projects in Punjab and Sindh during late
2013 and early 2014 that were meant to increase the power generating capacity
by up to 14000MW.
RECOMMENDATIONS:
To overcome present energy crisis, Pakistan needs to
take the following steps in form of:
1. Short Term Plan
2. Medium Term Plan
3. Long Term Plan
SHORT TERM PLAN:
· Increase the number of IPPs (independent Power
Producers).
· Reinstalled the closed power generating units.
· Improve the existing poor distribution system.
· Import electricity to fulfill the current need
for industries.
· Government should have strict check on energy
indicators on regular basis to counter such crisis in future.
MEDIUM TERM PLAN:
· Transformation of existing system to renewable
energy resources.
· Developing and installing biogas, solar, wind
and micro hydro based projects in villages.
LONG TERM PLAN:
· Developing and installing coal based power
houses.
· Initiate agreements for mega projects
with the energy extensive countries for sustainable energy resources.
· Exploration of more oil, gas and coal
reserves.
· Provide incentive for up gradation and
training to the engineers for new technology.
CONCLUSION:
Energy Crisis has, moreorless, plagued all sectors of Pakistan’s
machinery ranging from economy to industry, agriculture to social life,
inflation to poverty and it is hampering national progress in a drastic manner.
Nonetheless, menace of energy crisis can be overwhelmed by government through
making effective policies and its proactive implementation. Simultaneously, it
is the responsibility of us, the people of Pakistan, to utilize the available
energy astutely and wisely to play our due role for progress of the country.
Pakistan is moving in the direction of coal in the 21st century
which poses serious environmental challenges that have to be addressed. The
country needs affordable energy for its development and growth. Coal based energy
roadmap has to be developed together with development of additional gas
resources. Shale gas is another option that should be considered. Hydel power
potential also remains untapped. In USA, there is a separate department for
energy that formulates short, medium and long term plans to ensure sustainable
supply of this most important resource. Pakistan can also follow the same
approach.
