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
    • 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
    • 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-
    • 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. RECOMMENDATIONS These measures are must to give footings to industrial and commercial ventures in these technologies of 21st century. Some of the highly recommended incentives are as follows: % % % % % % % % % % % % • • • • • • • Formulation of long term strategies to include, progressively, the renewable/solar energy technologies in the national energy policy Provision of adequate funds for R&D and transferring the laboratory products into commercial products; Motivation of entrepreneurs through policy initiatives such as tax holidays, reduction/exemption from duties and taxes Provision of soft loans/subsidies to the end users Motivation through mass media, exhibition, field demonstration, education and training. Encouraging installation of solar lights and other appliances on public buildings, parks, streets etc Providing funds for renewable energy demonstration community projects.
