Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...PriyankaKilaniya
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

The government has ambitious targets for renewable energy, including 20,000 MW of solar power by 2022. Currently, renewable sources account for around 10% of India's total installed energy capacity.
This document provides an overview of renewable energy sources and development in Pakistan. It discusses how Pakistan is energy deficient and dependent on imported fossil fuels. To address this, the government created the Alternative Energy Development Board to promote 5% renewable energy generation by 2030. The document outlines Pakistan's significant solar, wind, and hydro energy potential and various government projects to develop these resources, such as installing solar home systems, issuing licenses for wind farms, and setting up micro-hydro sites.
The document discusses renewable energy systems and potential in India. It provides information on:
1. India's hydroelectric power potential of 145,000 MW and the potential from various river basins.
2. Details of some major hydroelectric power plants in India like Tehri Dam with capacity of 2,400 MW.
3. India's targets to achieve 175 GW of renewable energy capacity by 2022 and 450 GW by 2030, utilizing its estimated potential of 900 GW from sources like solar, wind, bioenergy, and small hydro.
4. The benefits of assessing technical potential as an upper limit and differences between technical, economic, and market potential for renewable energy.
Solar energy technologies refer primarily to the use of solar radiation for practical ends. All other renewable energies other than geothermal derive their energy from energy received from the sun.
Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic modules (also called photovoltaic panels) and solar thermal collectors (with electrical or mechanical equipment) to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
The development of a country is dependent on the per person energy consumption rate, which is very low
in Bangladesh. Bangladesh installed a capacity of 10416 MW electricity on June 2014 and three fourth of
which is considered to be accessible. Near about 45% people has no access to electricity. Therefore,
electricity shortage is an acute crisis in Bangladesh. As Saint Martin Island is far away from the main
land, it is almost impossible and cost ineffective to supply electricity from the national grid. For
connection of nearly 6000 peoples of Saint Martin to the main stream of development and to make this
island more attractive to the tourists, it is very essential to provide electricity for them. Power generation
by combining solar, wind and diesel, known as hybrid system can be the most efficient technique for the
electrification of these types of Island. Based on this principle, in this paper a hybrid system is designed
for electrification of Saint Martin’s Island. In the analysis, realistic data is used for load calculation and
optimization analysis for most effective solution. Hybrid Optimization Model for Electric Renewable
(HOMER) software is used to find out the final optimization and sensitive analysis of hybrid system. This
system satisfies the load demand and reduces carbon emission which will help to generate green energy.

This document describes the design of a hybrid solar-diesel power system for a community in Lagos State, Nigeria called Akodo that lacks access to the electric grid. The system was designed to meet the community's estimated load of 88.9 kW. It involves using photovoltaic panels, batteries, an inverter, and a diesel generator. Software modeling was used to simulate the system and analyze the costs. Key inputs included solar resource data for the location and load profiles for households and community buildings. The proposed hybrid system is expected to reliably and economically provide electricity to Akodo.
Analysis of Solar Diesel Hybrid off Grid System in Myanmarijtsrd
A hybrid system combining renewable technologies with diesel generators is a promising solution for village electrification. Shortage of electricity is the main obstacle for economic and social development. Myanmar has abundant renewable energy resource. There are many places that cannot supply electricity from the main grid. Tat Thit Kyun village is selected from these areas. The selected village where is situated Latitude 18°44N and Longitude 95°11E 5.6 mile away from Padaung Township is supplied by hybrid off grid system. 312 kWh demand is needed for 387 numbers of household. Data is obtained from Meteorological data of the village and NASA. The hybrid system is composed of photovoltaic source, diesel generator, battery energy storage system and converter. The hybrid system is analyzed for the life time 20 years by using HOMER software.

Solving Power Crisis of Bangladesh by Utilizing Renewable EnergyIJMREMJournal
This document provides an overview of the current conventional and non-conventional energy scenarios in Bangladesh. It discusses the various renewable and non-renewable energy sources available in Bangladesh, including solar, wind, hydroelectric, tidal, biomass and biogas energies. The document analyzes the potential and current status of development and usage of these different energy sources. It finds that while Bangladesh has many conventional and non-conventional energy resources, insufficient infrastructure and a lack of development of alternatives have posed challenges. Harnessing renewable sources like solar, wind and tidal could help meet future energy demands.
Present Conventional & Non- Conventional Energy Scenario in Bangladesh and It...Farzad Hossain
The approaching energy emergency, increased by the proceeding with the exhaustion of fossil fuels, complements the requirement for sending of Conventional & Non- Conventional energy resources in Bangladesh, now like never before some time recently. Despite the fact that hydrocarbon resources in the nation are restricted, the significant accessibility of Conventional & Non- Conventional energy sources as fossil fuels, natural gas, nuclear energy and hydroelectric energy offers chances of reasonable energy-based advancements like wave energy, energy from the Bay-of-Bengal and potential sources of geothermal energy. Insufficiency in the energy area is a noteworthy issue in Bangladesh, which obstructs the smooth financial improvement work processes. Along the lines, Bangladesh is confronting trouble to accomplish a generally maintained advance in the economy because of the absence of a sound energy security. With the goal of exploring this advance, this paper displays an exhaustive investigation of the contemporary Conventional & Non- Conventional energy situation and future prospect in Bangladesh as far as appropriation, research and infrastructural improvement in the nation. It has found the components that are valuable to diminish the current energy supply emergency and abridged the present energy situation, absence of foundation and customary energy sources to advance the Conventional & Non-Conventional energy sources to satisfy the energy request in future in Bangladesh.
This document provides an overview of hydropower development in India. It discusses:
1) The history of hydropower and its current status as a major source of electricity worldwide and in India.
2) The challenges facing hydropower development in India, including low exploitation of potential, power shortages, and declining proportion of hydro capacity.
3) The initiatives taken by the Government of India to promote hydropower, such as increased funding, basin-wise development, and simplifying approval processes.
Renewable energy sources – policies of indiaManish Rasal
This document summarizes renewable energy policies in India. It discusses how India currently relies heavily on non-renewable resources like coal, which has caused issues with demand and supply. To address this, India created the Ministry of Non-Conventional Energy Sources to promote renewable energy. The ministry has implemented policies like incentives for private renewable energy projects and requiring utilities to source a percentage of power from renewables. India has significant potential for hydro, wind, and solar power. The document evaluates India's policies in promoting the development and utilization of renewable resources.
This document provides information about global energy use, future demands, and conservation. It discusses how coal, natural gas, and renewable sources currently make up most global energy production. Future demands are expected to increase fossil fuel and renewable consumption significantly. The document outlines various energy conservation methods that can be implemented at personal and global levels, including improving efficiencies, reducing losses, and transitioning to more sustainable energy sources and transportation. Strategies for a sustainable energy future include both immediate solutions like optimizing existing assets as well as long-term strategies such as promoting new technologies and transitioning infrastructure.
Renewable power energy production the energy sustenance option for nigeriaAlexander Decker
This document discusses renewable power energy production as an option for meeting Nigeria's energy needs. It notes that Nigeria receives abundant sunlight and has potential for solar power production. Specifically, it receives an average of 3.5-7 kWh/m2/day of solar radiation. Biomass is also widely available across Nigeria and has potential to generate 442MWe of energy. The document aims to highlight how renewable energy sources like solar and biomass could be developed to deliver megawatts of energy to the national grid and provide a renewable energy plan for Nigeria. It argues that solar and biomass technologies could help address Nigeria's problem of inefficient electricity distribution and unreliable power supply by harnessing the abundant solar and biomass resources.

This document discusses renewable energy and green technology. It defines energy and lists different forms of energy, including electrical, mechanical, chemical, heat, and nuclear. Energy resources are classified as either primary/non-renewable sources like coal, oil, and natural gas, or renewable sources like solar, wind, biomass, and geothermal that recur naturally. Renewable sources are attractive because they are inexhaustible, have low operating costs, are site-specific so transmission is not needed, and cause less pollution than fossil fuels. However, renewables also have disadvantages like low energy density requiring larger plants, intermittency due to varying natural conditions, lower efficiencies, and higher upfront costs.
— Energy and related sectors play a key role in the developmental profile of Sri Lanka. Energy demand is going up and up with time due to population growth and industrial revolutions. In order to meet such growing needs probably we are relying on fossil fuel in a large fraction, which is leading to many negative environmental impacts. Hence the government decided to take off many long term as well as short term planes to promote renewable energy sector in Sri Lanka as it gives minimum impact to environment and its quality than the fossil fuel. This paper gives basic information about renewable energy resources of Sri Lanka and their development &future perspectives.

• CONCLUSION
• SOURCE OF INFORMATION
3. The interest in renewable energy has been revived over last few years, especially
after global awareness regarding the ill effects of fossil fuel burning. Energy is the source
of growth and the mover for economic and social development of a nation and its people.
No matter how we cry about development or poverty alleviation- it is not going to come
until lights are provided to our people for seeing, reading and working.
Natural resources or energy sources such as: fossil fuels, oil, natural gas etc. are
completely used or economically depleted. Because, we are rapidly exhausting, our non-
renewable resources, degrading the potentially renewable resources and even threatening
the perpetual resources. It demands immediate attention especially in the third world
countries, where only scarce resources are available for an enormous size of population.
The civilization is dependent on electric power. There is a relationship between GDP
growth rate and electricity growth rate in a country. The electricity sector in Bangladesh
is handled by three state agencies under the Ministry of Energy and Mineral resources
(MEMR).
These are
• Bangladesh Power Development board (BPDB)
• Dhaka Electric Supply authority (DESA)
• Rural Electrification Board (REB)
Bangladesh is a largely rural agrarian country of about 120 million people situated
on the Bay of Bengal in south Central Asia. Fossil energy resources in Bangladesh
consist primarily of natural gas. Domestic oil supply in considered negligible. Several
small deposits of coal exist on the north eastern region of the country, but these consist of
peat, with low caloric value and very deep bituminous coal that will be quite expensive to
extract. Only 15% of the total population has got access to the electricity. In 1990 only
2.2% of total households (mostly in urban areas) has piped natural gas connections for
cooking and only 3.9% of total households used kerosene for cooking. These are by no
means a pleasant scenario.
Per capita consumption of commercial energy and electricity in Bangladesh is one
of the lowest among the developing countries. In 1990, more than 73% of total final
energy consumption was met by different type of biomass fuels (e.g. agricultural
residues, wood fuels, animal dung etc.).
The rural and remote sector of Bangladesh economy, where 85% of the population
live, is characterized by an abundance of open and disguised unemployment, high Man-
land ratio, alarmingly large numbers of landless farmers, extremely inadequate economic
and social facilities, low standard of living and a general environment of poverty and
deprivation.
Larger energy supplies and greater efficiency of energy use are thus necessary to
meet the basic needs of a growing population. It will therefore, be necessary to tap all
4. sources of renewable energy and to use these in an efficient converted form for benefit of
the people. Primarily this will be done in remote inaccessible un-electrified area in a
stand alone system where grid expansion is expensive.
This energy conversion will reduce pressure on the national power demand. This
will not only save excessive grid expansion cost but will also keep environment friendly.
Recently a number of experimental and pilot projects are being undertaking by different
organizations in different sectors of alternative energy technologies in Bangladesh. Some
preliminary information on the main pilot projects of different energy technology are
discussed in this paper.
5. RENEWABLE ENERGY RESOURCES AND TECHNOLOGIES IN
BANGLADESH.
Bangladesh is endowed with plentiful supply of renewable sources of energy. Out of
various renewable
sources solar, biomass, peat, and hydro-power can be effectively used in Bangladesh
(Government of
Bangladesh, 1991). Renewable energy practices in Bangladesh are
• Solar Energy
• Wind Energy
• Biomass Energy
• Αatomic Energy
• Hydro-power energy
•Solar Energy
Solar energy technology in Bangladesh
1. Solar PV System:
Rural electrification Board (REB), Atomic Energy Commission (AEC), Local
Government Engineering Department (LGED), and Grameen Shakti (GS) have installed
(are in the process of installation of ) a number of solar PV systems in different parts of
the country.
REB has undertaken a pilot project for supply of solar electricity in some islands of one
main river (Meghna) in Narshingdi district. Five types of PV systems are delivered to
1370 consumers as shown in
Table -1 below:
Table- 1 : PV Systems in the REB Pilot Project.
6. Under this project, PV systems have been installed at one rural health clinic for
running fans, lights and refrigerators. Same systems are being set up in another clinic.
The first solar module was installed on 3rd August 1996 and since then till 10-05-97 a
total households have been provided with different types of systems as shown in Table-2:
Table 2. Progress of Solar PV installation as
7. More than 500 potential consumers have been trained on the operation and
maintenance of the entire PV system. This was conducted by BCAS and CMES experts.
AEC initiated solar PV program (SPV) in 1985. The systems installed over the
period 1985-1994 are 9790 watt peak. Most of the systems are not functional at present
because of the lack of fund for spare parts, maintenance and back-up service.
LGED has so far installed SPV systems in 5 cyclone shelters, one at Cox’s Bazar,
four at Patuakhali. According to LGED all the systems have been working satisfactory
since their installation. During the year 1996-1997, GS has installed 67 units of solar
home systems (SHS) at different districts of Bangladesh. This includes Fluorescent Tube
lights, T.V. point, Fluorescent lamps etc. GS is planning to install a total of 400 under
next phase of the solar PV development project.
2. Solar Cookers:
Institute of fuel Research and Development (IFRD) of BCSIR and Centre for mass
Education in Science (CMES) is engaged in the development and dissemination of solar
cookers. A low cost reflector type cooker developed by IFRD is a spun-aluminum
parabolic reflector. It is light weight (2-3 Kg), cheap and simple to construct, but the
disadvantages are that it needs manual sun tracking frequently and the reflectivity
deteriorates rather rapidly and cooking is interrupted by cloudy and hazy conditions. On a
bright sunny day a 42 inch aperture spun aluminum cooker takes about three hours for
cooking three items (rice, fish or meat, pulses) for a family of 5-6 members in
Bangladesh.
3. Solar Oven and Dryer:
Different models of solar ovens have been designed and constructed with
locally available raw materials. The institute of Food Science and Technology (IFST) has
developed a cabinet dryer for drying fruits, vegetables etc. by simply spreading a
transparent cover over a box. These dryers are made of bamboo and polythene sheet.
4. Solar Water Heater:
This heater is designed and constructed by IFRD. It consists of coated flatplate
which absorbs solar radiation, convert into heat and transfers the resulting heat to
circulating water.
This type of heater is useful for supplying low grade thermal energy at temperatures
below 90 0C.
8. •WIND ENERGY
Of the several available option of renewable energy, wind systems have captured
interest for a long time. The modern development of wind turbines was started from 1973
and the main achievement of this development lies in the improvement of aerodynamic
efficiency and reliability, leading to lower costs per kWh generated. A great deal of
information has been gathered in the past two years on the wind energy potential along
coastal Bangladesh. The potential of wind energy in the coastal areas of Bangladesh is
very high but this cannot be determined accurately until sufficient good quality data on
wind speeds over at least twelve months of the year are available in different location.
Bangladesh Centre for Advanced Studies (BCAS) with the assistance from Overseas
Development Administration (ODA) of UK launched the Wind Energy Study (WEST)
Project in October 1995. The aim of this project is to assess the potential of utilizing wind
energy as mechanical and electrical power. They collect and analyze wind speed data at
seven areas of Bangladesh. The locations are widely dispersed along the vast coastline in
the district of Cox’s Bazar, Chittagong, Noakhali, Bhola and Patuakhali. The average
wind speed of those locations is shown in Figure below.
The data obtained by meteorological department have been assessed by
Bangladesh University of Engineering and Technology (BUET). The data show a
prospective source of wind energy in many places in Bangladesh.
The wind speed in some regions of Bangladesh is satisfactory for operation pumps
and for generation of electricity. The wind turbines may also be useful to drive hand
pumps used in irrigation agricultural land.
9. It was found that the wind speed in Chittagong is 2.57 m/sec or more for 4000
hours a year. At this available speed a wind plant can be operated both for generation of
electricity and for driving pumps. Grameen Shakti has been assessing the wind resource
at Chokoria, Cox’s Bazar as well. Till now, the activities regarding wind energy are
related to wind resource assessment only.
There has been little investigation of potential markets for wind power. There are
some industries along the Bay of Bengal coastline using wind power for electricity
supply.
These are shrimp farming, fish processing, and ice making industries. These are all
electricity intensive and represent major industries along the coast, especially in the
Cox’s Bazar, Chokoria, and Chittagong, and Khulna areas. Many of these industries are
in areas without electrical grid availability, and rely on diesel generator to provide
electricity. In particular, there are a number of islands, such as Mohaskhali near Cox’s
Bazar, that could be important locations for fish and shrimp related industry, but that are
far from the grid and are not likely to receive grid connection in the near future due to the
high costs of running the trunk lines out to these islands.
These islands may also have among the highest wind speeds in the country. Site for wind
turbines needs wind speed at least 6 m/s. goo accessibility of the location for heavy
transport and cranes, wind direction, soil condition, noise, birds, disturbance of
landscape, TV and radar reception interference should be considered for wind turbines
installation.
•BIOMASS ENERGY
Biomass energy is the important source of energy in many countries of the world.
It is oldest type of fuel which men used for centuries after discovery of fire itself. The
increase in population has forced larger numbers of rural poor to use the forests
unsustainably for fuel-wood, bamboo, fodder, game meat, medicines, herbs and roof
materials. Deforestation will upset the natural recycling system as well as increase the
cost of fuel wood required, both in time and money, creating a vicious circle and further
deforestation. Forest in many developing countries are disappearing at a high rate.
Major problems are facing Bangladesh are food and fuel. In Bangladesh,
commonly known Biomass fuels are: fuel wood, agricultural residues and animal dung.
The country has naturally high potential for production of Biomass resources; but
because of high growth rate of population (2.4%) forest cover is being reduced in an
alarming proportion.
10. In Bangladesh, while looking at over all energy consumption over the past 15
years, Biomass energy contributed 83% in 1980-81, 73% in 1989-90, and 67% in
1994-95. With the growth of GDP, consumption of commercial fuel increased more
rapidly than that of Biomass fuel.
Alternative technology for Biomass energy
1. Improved Stove:
In the institute of Fuel Research & Development (IFRD), BCSIR both single and
multiple stove have been modified to give fuel saving to the extent of 50-70%. There are
several NGOs like Swanirvar Bangladesh, VERC, BACE, Bandhujan Parishad, AID-
Bangladesh, and TSP are engaged in dissemination of improved stoves under Fuel Saving
Project and have achieved some
success.
2. Biogas technology:
Biogas is a kind of gas obtained by anaerobic fermentation of animal and
agricultural, wastes or other words any thing which decomposes on standing. There are
two models one is the floating cover design and the other is the fixed top design are used
in Bangladesh.
Bangladesh Agricultural University (BAU) first setup a biogas plant in the
University campus in 1972 to study the gas production characteristics and later set up a
family size plant. Department of Environment (DOE) started the programme in 1981
under a government grant. Under the “Fuel Saving Project of BCSIR”, the gas holder was
supplied free of cost on condition that the owner would bear the cost of the digester and
other accessories which usually involved approximately half the total cost. The IFRD of
BCSIR in collaboration with Dhaka City Corporation built an experimental biogas plant
of 85 M3 digester volume in 1992 for treatment of city garbage. So far, about 1000
biogas plants have been installed in the country.
Since the current status of the technology, 4-5 cattle heads are needed for a family
size plant, therefore only the well-to-do families of rural areas can be brought under
biogas programme. As seen in the table -3, only upper 20% of the rural households own
more than four cattle head.
Table -3. Cattle heads per household of the rural areas of Bangladesh.
Farm size (acre) Cattle/house-hold (av. no.) House-hold (% of the total)
0-0.99 0.40 59
1.00-2.49 2.24 21
2.50-7.49 4.40 16
7.50 and above 6.80 04
11. Recently a project entitled “biogas pilot plant” worth Tk. 68.96 million has been
approved by the Government of Bangladesh and being implemented by IFRD, BCSIR.
The objectives of the project are
To provide alternative sources of energy to the rural people for cooking,
lighting, irrigation and electricity generation.
To provide organic fertilizer, rich NPK and micro-nutrients of the soil.
To improve hygenic and sanitary conditions of the rural areas.
To check deforestation and maintain ecological equilibrium.
Barriers for Sustainability of Alternative Energy Technologies:
1. High initial cost
2. Dependence on the weather
3. lack of awareness
4. Lack of established high-volume supplier-dealer chains.
5. High prices of the components.
6. Lack of fund.
Under the circumstances sustainability depends on the correct design of the
installment payment mechanism that takes into consideration recipients’ cash constraints
and the upper limit of the amortization period. According to Mr. Eusuf (1997), it is well
known that for any new systems and as such effective post installation monitoring and
services must be ensured.
• Αatomic Energy
MoU binding Bangladesh and Russia on nuclear power plant
Bangladesh Joint Venture Rosatom Russia
Bangladesh and Russia Wednesday signed a memorandum of understanding (MoU) to
enhance cooperation between the two countries in peaceful use of nuclear energy.
Main purpose of the MoU signed between the state-owned Bangladesh Atomic Energy
Commission (BAEC) and the Russian State Atomic Energy Corporation-Rosatom, is to
take necessary steps for setting up a 600-1000 MW power plant in Bangladesh, officials
said.
“This is a great moment for us. Through signing of this agreement, we are moving
forward to implement our election commitment to build up a nuclear power project,”
Science and ICT State Minister Yeafesh Osman said at the signing ceremony.
12. NN Spasskiy, Deputy Director General of Rosatom, who signed the agreement on
Russian part, said, “This agreement will enable us to provide avenue for cooperation in
peaceful use of nuclear energy. But one thing is in our mind to design and build
Bangladesh’s first nuclear power plant.”
BAEC acting chairman Mosharraf Hossain signed the MoU on behalf of his organization.
Both sides, however, termed the MoU a very preliminary stage after an initial
negotiation. If negotiation proceeds on, a state level agreement will be signed later.
The science and ICT state minister Osman said that Bangladesh has earlier signed similar
agreements with China and the United States.
“We will seek proposals from other countries and finally accept the one which will be the
most competitive for Bangladesh,” he said.
The state minister said it might take 4-5 years to implement the planned 600-1000 MW
nuclear power plant in Rooppur site, in Bangladesh’s western Pabna district, about 200
km from capital Dhaka. The cost of the plant might be 1.5-2 billion U.S. dollars.
Spasskiy, also head of Russian delegates who arrived here on Tuesday, said Russia is
confident that its proposal will be “quite competitive.”
Official sources said the MoU includes taking necessary measures for installation of
reactors for power generation and development of other infrastructures for setting up a
nuclear power plant, supply of energy for the plant and operation and maintenance and
also the waste management of the plant.
A Bangladeshi delegation is now planning to visit Russia to see Russia’s nuclear power
plants and also may hold final negotiation.
Bangladesh’s Prime Minister Sheikh Hasina in March told the national parliament that her
government, which took office on Jan.6 this year, will set up a nuclear power plant to meet the
growing demand for power.
• Micro hydro energy Programme:
LGED with its Sustainable Rural Energy (SRE) project has successfully demonstrated
first micro-hydro power unit at Bamerchara, Chittagong. Its installed capacity was 10kW
but due to inadequate water head about 4kW power was generated. SRE has also carried
out a study on prospective micro-hydro sites in the Chittagong Hill Tract reasons and
eight potential sites were identified with an estimated capacity of 135kW. SRE also
provided technical support to promote indigenous micro-hydro power generation unit
which was developed by member of local indigenous community named Mr. Aung Thui
Khoyan.
