Traditional Energy Sources of Tajikistan Fuel Resources Coal. Predicted coal reserves in Tajikistan are estimated to be 4-5 billion tonnes, and industrial and prospective reserves for coal deposits are 1 billion tonnes. It is necessary to use the latest extraction and raw material processing technology in order to avoid harming the local ecology. Oil and Gas. Of the energy resources of Tajikistan, oil and gas makes up around 3%. Assumed depths of deposits of productive oil beds are 6000 meters or more. Hydro resources: Potential resources of Tajikistan make up more than 500 billion kWh, currently 5% is realized.

Problems with supplying energy and ecology Problems. A critical shortage of organic fuel, difficulty in delivering it to the mountainous regions of Tajikistan, continuous increase in price for electric power, and lack of electric power in many places that are far from main power lines, all force inhabitants of mountainous regions to use wood for fuel. This causes the destruction of otherwise scant woodland, whose area has already decreased 5-10 times, and in certain parts of the wooded areas have completely disappeared. The stripping of mountainous slopes leads to an increase in mudslides, soil washing away on slopes, and as a concluding consequence desertification, essentially causing a double greenhouse effect.
Renewable Energy Source Potential (1) 1. Potential for small hydropower The potential of small and mid-size rivers of the Tajik Republic is greater than 30 million kW and their annual electricity output is about 100 billion kWh per year. On the inflow of the river, in the mountainous region of the Republic, it is technically possible and economically appropriate to build more than 1000 small hydropower stations with a power capacity ranging from 10 to 3000 kW. The technical assessments and cost estimates for 14 prospective small hydropower stations show that their average annual output can be 348 million kWh with a total capital investment of $44 million.
Renewable Energy Source Potential (2) 2. Solar Energy The average total length of sunlight per year is hours. The places that see a minimum amount of sunlight are- the mountain station of Dekhavz (2097 hours) located in the upper reaches of the Zarafshan River at a height of 2500 meters and on the Fedchenko Glacier that has a height of 4169 meters and gets 2217 hours. The maximum length of sunlight (more than 3000 hours) is found in the southern part of the Republic (meteorological station Pyanj hours), and also in Eastern Pamir (meteorological station Karakul hours).
Renewable Energy Source Potential (3) 2. Solar Energy The total solar radiation on a clear day reaches МJ/ sq. m. Assessments show that solar energy can meet 60-80% of the needs of the countrys population for 10 months of a year. Converting this to its fuel equivalency brings this number to equal about 400,000 tonnes of fuel equivalent, which would equal 460 million cubic meters of gas or 528,000 tonnes of fuel oil.
Renewable Energy Source Potential (4) Wind Energy The strongest winds are in the highland areas with open forms of reliefs (Fedchenko Glacier, Anzobskiy Pass, and others) and in those areas where orographic factors have served conducive to increased pressure gradients (Khudzhand, Fayzabad, Shuroobod). The average annual wind speed in these areas reaches 5-6 meters/second. In open plains and in wide valleys, wind speeds are somewhat slower- 3-4 meters/second. In closed basins and in lowlands in the southern regions wind speeds do not exceed 1-2 meters/second.
Renewable Energy Source Potential (5) Biomass From the total amount of biomass available only 0.5% is consumed by humans in the form of food. The use of biofuel in the form of firewood, manure, and leafy tops of rooted vegetables are of paramount importance to about 50% of domestic households around the planet, supplying energy from these sources and creating in total around 300 GW. Biogas generator (methane tank) with a volume of 2 – 3 м³ that uses about 8 kg of manure daily (from four cows) makes up to 2 м³ of biogas per day. This is equivalent to a continuous output of 300 W of thermal energy.

Laboratories and experience for researching and using renewable energy sources in Tajikistan (1) Since 1980 in the laboratory of the Solar Radiation Engineering department of the Physics-Technical Institute of S. U. Umarova Academy of Sciences of the Republic of Tajikistan, there has been ongoing scientific research and experimental designs for creating cells and devices that use solar energy. From the laboratory was converted into the Center for Research and Use of Renewable Energy Sources as a part of the Physics-Technical Institute of S.U. Umarova Academy of Sciences of the Republic of Tajikistan.
Experience in researching and using renewable energy sources in Tajikistan (2) There have been technological developments for producing solar water heaters that can make from 0.1 to 1 tonne of hot water (50-70 degrees Celsius) in the course of one daylight day. Production with a 1 sq. meter solar collector per unit is 80 to 100 liters of hot water Some samples of these devices have been created and tested. Developed and produced solar kitchens, created to prepare food using solar energy. The product allows a family to prepare food twice a day. The temperature inside the device is degrees Celsius. There is currently ongoing research on solar panels that are used for converting solar radiation into electricity.

Experience in researching and using renewable energy sources in Tajikistan (4) International Cooperation In partnership with the Academy of Sciences of the Republic of Tajikistan, the representatives of the European Commission in Tajikistan, obtained and installed in varying locations of Dushanbe and Kurgan Tube several solar water heaters that are meant to produce hot water as well as several solar photovoltaic modules for receiving electricity. This was done as part of the Use of Solar Energy in Tajikistan project.
Strategy and Priority- the direction of policy towards renewable energy use in the Republic of Tajikistan. The government of the Republic of Tajikistan, February 2, 2007, no. 41, approved, C omprehensive program to target the widespread use of renewable energy sources, such as the energy of small- rivers, solar, wind, biomass, and underground sources for Executing Program: Academy of Sciences of the Republic of Tajikistan, institution of higher learning, Ministry of Energy and Industry of the Republic of Tajikistan, Ministry of Agriculture, and Committee on Environmental Protection of the Republic of Tajikistan. Stages and the deadlines for realizing the Program: stage 1 – ; stage 2 – ; stage 3 –
Realizing the PROGRAM (1) Goals and Objectives of the PROGRAM: Creation, developing, and widely using prospective technology for producing electrical and thermal energy that comes from renewable energy sources. Implantation of modern technology that uses renewable energy sources into the countrys energy balance. To train engineers and highly-skilled specialists in the field of renewable energy sources.
Realizing the PROGRAM (2) Creating Infrastructure For successful realization of the PROGRAM it is necessary: - to organize a design bureau for developing, producing, and distributing components and renewable energy sources devices; - to create a construction and assembly organization; - to create a Scientific and manufacturing department.
Realizing the PROGRAM (3) Legislative Base In the Republic of Tajikistan it is necessary to adopt the law On Alternative Sources of Energy, which together with the current Program will form the necessary normative-legal, economic, and organizational foundation for widespread use of renewable energy. It is necessary to offer incentives to both consumers and producers of renewable energy. Should permit imports on preferential terms of equipment and the corresponding components that are needed for renewable energy use. Should make favorable conditions for the creation of joint ventures for progressive production technology, producing modern cells and solar energy plants as well as other forms of renewable energy.

Conclusions and Recommendations (1) 1. Tajikistan has an immense reserve of energy resources. At the same time, it is impermissible to have a careless attitude towards them and to use these gifts of nature in a wasteful manner. 2. The long-term politics of the supply of energy to the country must include a maximum and rational use of all forms of energy resources, while also making sure to consider using high performance technology to convert energy, supply energy, conserve energy, and protect the surrounding habitat.
Conclusions and Recommendations (2) 3. It is necessary to efficiently provide energy to the countrys population. Renewable energy sources present in the regions should be used first. 4. At the same time, there exists a number of problems with the wide-spread expansion of renewable energy. In order to overcome these challenges the government and the international organizations assisting in the introduction of alternative sources of energy, must increase efforts to transfer modern technology as well as provide financial and legal support. 5. This will enable not only to preserve the ecology of a mountainous country, but it will also improve the living conditions of the population and decrease the level of poverty.
