COUNTRY’S PROFILE
Pakistan is a land of nearly 155 million people living in an area of 800,000 sq. km. The landscape
varies from lofty Karakoram and Himalaya mountains, with the K-2 peak (second highest in the

4. world: 8,613 meters) to the famous desert of Thar and includes fertile plains of the river Indus and
its tributaries. Pakistan is known as a land of natural beauty, grandeur and is the home of a culture
as ancient, complex and striking as any in the world. It also is the birth place of Indus valley
civilization. Pakistan has dominantly agricultural economy and is striving to develop and expand
industrial base.
CONVENTIONAL ENERGY PROFILE
Pakistan, despite enormous potential of energy resources remains energy deficient and has to rely
heavily on imports to meet its requirements. Pakistan obtains its energy needs from variety of
traditional and commercial sources. Oil supply from indigenous resources has been the weakest link
in the energy supply system of Pakistan. Until early 1980 crude oil production was nominal 13000
barrels per day (BPD), which rose to 64,350 BPD in 1991-92. Production is declining and current
production is 59000 BPD, with this rate the remaining oil reserves 253 million barrels will be
depleted in about 12 years. Consequently, it appears that Pakistan would continue to remain a net
importer of crude oil and refined oil products unless a major discovery of oil is made.
RENEWABLE ENERGY SOURCES
The role of renewable energy resources such as solar, wind or biomass has been negligible in the
total energy picture of Pakistan. The experiments in the past in this area were not so successful due
to variety of reasons including lack of understanding and handling of these technologies. The units
installed at initial stage have not increased much as envisioned.
RENEWABLE ENERGY SOURCES

5. It has now become clear that in near future the environmental friendly Renewable Energy
Sources are to be developed and popularized for the sustainable development. Other incentives
for promotion of such energy technologies, particularly in the developing world, are clean
environment, energy independence, new employment opportunities, improvement of living
conditions in rural areas, and reduction in mass migration from rural to urban. Today the
primary energy supplies are not enough to meet even the present demand. So, Pakistan, like
other developing countries of the region, is facing the serious challenge of energy deficit.
Solar energy is most abundant, widely spread and very clean source of energy. It has wide range
of applications. It can be used to warm and cool the buildings, heat the water for industrial and
domestic applications, distill the water for health purposes, dry the agriculture products, and can
easily be converted in to other forms of energy such as electricity. Most of the solar energy
technologies are becoming economically competible.
PHOTOVOLTAIC.
The best way to utilize the solar energy is no doubt through photovoltaic’s which converts the
sun energy directly into electricity – the most demanding type of energy. During last fifteen years
Pakistan has shown quite encouraging developments in this field. National Institute of Silicon
Technology (NIST) under the Ministry of Science and Technology has already developed the
know-how and technology to fabricate the solar cells, modules, and systems. Photovoltaic is
particularly suitable for small power requirements and remote area applications. Pakistan took a
lead in the region, in using photovoltaic. In early 1970’s a total of eighteen P.V. stations in
different parts of the country were-4-set up for village electrification. The total installed capacity
of these was nearly 440 KW. Because lack of technical know-how and no follow up, these
systems have not given the required benefits. Now NIST has developed the know-how and
technologies and basic infrastructure in the field. Currently technology is being used, in Pakistan,
for standalone rural telephone exchanges, repeater stations, highway emergency telephones,
Cathodic protection, refrigeration system for vaccine and medicines in the hospitals etc. Public
Health Department has installed about 20 units of Solar Water Pumps for drinking purposes in
different parts of Baluchistan. Both the private and public sectors are playing their roles in the
popularization and up gradation of photovoltaic activities in the country. A number of companies
are not only involved in trading photovoltaic products and appliances but also manufacturing
different components of PV systems. They are selling P.V. modules, batteries, regulators,
invertors, small power practical gadgets for load shedding such a Photovoltaic lamps, battery
chargers, garden light etc.
Energy technologists are now convinced that the development and adaptation of solar
energy technologies can bring a revolution in the life style and living standards of low-

6. income people in extreme remote areas.
For solar energy technologies, quite an infrastructure and know how, at the R&D and limited
production levels, already exists in this country. However, for its promotion, there is a need to
take certain drastic measures for providing incentives and funds for its practical demonstration;
convincing the people for their utilities; educating the masses and developing the pilot scale
activities. These measures are must to give footings to industrial and commercial ventures in
these technologies of 21st century.
