Contents of Presentation • The presentation includes an analysis of energy resources (both renewable and nonrenewable), and the possibilities and prospects for using renewable energy sources. • Experiences in research and utilization of renewable energy sources in Tajikistan (installation and devices that use renewable energy sources). • Strategy and Priority- the direction of policy towards renewable energy use in the Republic of Tajikistan. • To state the principal objectives of the government program “On approval of a comprehensiveprogram to target the widespread use of renewable energy sources, such as the energy of small-rivers, solar, wind, biomass, and underground sources for 2007-2015” • Conclusion and Recommendations
Traditional Energy Sources of Tajikistan Fuel Resources • Coal.Predicted coal reservesin 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.
Tajikistan’s Energy Resources Energy Resources mill.t.f.e. (tonnes of fuel equivalent) • Oil 37.0 • Gas 15 • Hydro 64.7 (per year) • Coal 867.3 • Renewable Energy Sources - ???

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 stationswith 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 2500-3000 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- 3029 hours), and also in Eastern Pamir (meteorological station Karakul’- 3166 hours).
Renewable Energy Source Potential (3) 2. Solar Energy • The total solar radiation on a clear day reaches 7500-8000 МJ/ sq. m. • Assessments show that solar energy can meet 60-80% of the needs of the country’s 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.
Appraisal of renewable energy sources and possibilities for their use • Small rivers • Solar • Biomass • Wind • Geothermal Sources
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 01.01.2008 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 100-130 degrees Celsius. • There is currently ongoing research on solar panels that are used for converting solar radiation into electricity.
