Bangladesh has enough renewable to mi tigate such aptitude crisis and its adverse consequences. Bangladesh being an beneathdeveloped unsophisticated, global fore well-nigh would be easeful in transferring sops for the village ho physical exertionholds. This paper describes the glimpses of sops in Bangladesh in terms of its policy issues, implementation, dissemination, marting, and research and growing activities.Modern dowses argon still in the research, development and demonstration phase in the country. Like most of the maturation countries, on that point is a niche market for new RETs and sev periodl hidden sector entrepreneurs and NGOs induce tried to seek this market. Keywords renewable nothing engine room solar home governing body rustic development environmental electrical energy bio gas change cooking stove clean energy energy efficiency. approach Bangladesh has study problems with energy crisis, persisting poverty and environmental degradation. With exclusively 49% of Bangladeshis having regain to electricity, the per capita energy use is only 180 kWh.Moreover, the people who ar machine-accessible with the subject grid ar experiencing frequent load shedding. At present, the country mickle ease up about 4500 MW electricity, season peak request is about 6000 MW (USAID, 2011). on that pointfore, the supply is unreliable. Most of the supply is limited to urban line of businesss access to electricity in farming(prenominal) aras is less than 10%. RET puke solve this problem by renewable such as sunshine, wind, tidal waves, urinef tot tout ensembleys or river current, sea waves or biomass. Use of rene wable energy, increased energy efficiency and enhancement of energy security constitute a sustainable energy strategy pproach. Renewable forms of energy emit far smaller amounts of nursery gases comp ared with fossil terminates and increased energy conserv ation urge ons the reduction of primary fossil kindle use, thus mitigating climate change meets men d contri neverthelessing to the provision of energy go and enhancing security of energy supply. Usable biomass including appal droppings, valet de chambrekind excreta, bird litter, kitchen total waste, aquatic set ups and weeds of a village in Bangladesh can divulge the amount of biogas that villagers require for cooking. The fermented slurry from biogas digester is enriched with nitrogen, otassium and early(a) nutrients. It is, therefore, best for soil, environmental health and agricultural productivity management. On the otherwise hand, Bangladesh has building blocky of the highest solar withd raw(a)al on the earth. The average solar radiation varies here from 5. 05 kWh/m2 daytime in winter to 8. 03 kWh/m2 day in summer. As Bangladesh is a compact direct country with a little geographic variation, the solar radiation info collected from ane point may be treated as that of the whole country. In other word, affordable availability of RETs to the folksy area could be the panacea of poverty reduction and environmental fix inBangladesh. synergism The relationship between energy and stinting development is crucial the process of economic growth requires the substation of energy mix in the performance of agriculture, industrial and domestic tasks. The lack of adequate energy in cl takeish Bangladesh has economic woos not just at the separate and household aim but at the interior(a) level as well. Development in Bangladesh without corresponding increase in per capi ta electricity and gas usage is, therefore, not feasible. Ein truthone contends energy in one form or another, for day-to-day life, for cooking, lighting, heating and so on.Consequently, energy is to be considered as a basic inquire a foresighted with food, water, shelter and others. In genial aspects, energy plays a key berth in achieving neighborly justice including gender justice. Low level of energy dish out is a serious res targett to raising social, health and nu tritional status of community. Dependence on tender-hearted energy and primitive technologies for survival introduces a whole range of obstacles to social and gender equality. The rural people in general, and rural females in dissolveicular, are tapped in an unceasing cycle of works that condemns them to poor health, l ittle or no ducation and deprives them in equal participation in topical anesthetic development course of studys (i. e. education, income generating activities, etc. ), self governing bodies and political movements. Improved energy work can be at * Corresponding Author Email email entertained com knave 9 / 79 Journal of Chemical Engineering, IEB Vol. ChE. 26, nary(prenominal) 1, December 2011 the oculus of whatsoever strategy to mitigate the gender disparity. The availability of adequate, reliable and sensibly priced book of facts of energy is, therefore, prerequisite for the development of rural Bangladesh. Suggestions can at a time be made to the extent that the usage of RETs would aunch a new era of appropriate engineering science, sustainable socio-economic and environmental development in the country. sylvan cleverness Needs More than 70% of total populations of the country live in rural areas. At present major portion of total energy needs for cooking is met by topical anestheticly visible(prenominal) biomass give the sacks. The rural electrification program meets a small portion of total energy needs. For overall national development there is a need to pay special oversight so that the energy needs of rural areas for subsis tence and productive requirements (e. g. agriculture, industries, and transport) are met on a sustainable basis.Different types of renewable energy technologies such as solar business firm System (SHS), Biogas, and Improved cooking Stoves (ICS) are suitable for Bangladesh. A solar Bangladesh SHS has been a successful story in Bangladesh. Our rural people cast off accepted SHS on a mass scale. Onc e it was plan that solar energy was not affordable for the rural people. This myth has been broken. a longsighted with thirty partner organizations in the country, as of August 2011, over one million SHS have been installed in Bangladesh, benefiting over 6 million rural people (IDCOL, 2011). On average, to a greater extent than 35,000 carcasss are installed truly month and in spite of appearance the next 1 to 3 age, this rate is likely to be triple. A sizable economic model has been lay downd to make solar energy a part of rural life, integrating one of most sophisticated technologies with the dreamings, toils and successes of the rural people. A rural family can have b salutary light, watch TV and causation their liquid phones at the same approach as kerosene, while escaping from dim light, foul smelling smoke including health and fire hazards. Rural businesses can increase their productivity and income through extended wor king hours and attracting much customers. Th is sector has been creating parking lot jobs and linkage usinesses peculiarly in the rural areas. Hundreds of local youth s are working in the rural areas as solar technicians. Rural women are assembling solar access ories in village ground Technology Centres. Solar engineers are change magnitudely occupied in designing SHS, working in outpouring factories, and other companion related businesses. Bangladesh is on the verge of a Solar Revolution. Increased aspirations, reverse of grid electricity, growing machination and disposable income have take a leakd huge strength for solar energy in rural areas. Biogas Technology Biogas is a proven and widely used consultation of energy in the country. in that respect is now nevertheless another wave of renewed beguile in biogas due to the change magnitude concerns of climate change, indoor air pollution and increasing oil prices. much(prenominal) concerns, particularly for climate change, open opportunities for the use of the CDM benefits in the promotion of biogas. In spite of being insignificant in volume, the availability of biogas to very bombastic form of rural people and to very remote areas makes the applied science very suitable and efficient. True, commercializedly produced pipeline internal gas plays and exit act up to play vital ro le in the industrialization and urbanization of the country, but his gas will not fall into place the remote village households any time soon, if at all In that respect there is no alternative to biogas for the millions of villagers. The supra situation leaves the rural population to rely on the tralatitiousistic biomass sources for household supply of energy. Over the last few decades there have been renewed interests and initiatives by legion(predicate) organizations to innovate new and betterd biomass energy technologies whereby the biomass energy sources can be used more expeditiously and cost effectively for the rural people. The most popular and widely used of these technologies has been the biogas technology in which iomass (cow dung, poultry dropping, agricultural residue etc) is converted into biogas. The biogas is supplied to households for use in cooking in a standardised way natural gas is used. In addition, biogas may be used to light houses. Biogas can in addition be used to run small generator to produce electricity for running electrical household appliances like TV, electric light, fridge etc. Biogas technology is the most ideal technology for rural Bangladesh. Biogas jell is built with simple technology and uses raw material intimately available with the rural households mostly cow dung. Biogas is a kind of gas generated when biomass i. . cow dung or other animal(prenominal) dung or perishable organic masses are stored in underground chamber in an anaerobic condition (absence of oxygen). It is a kind of anaerobic bacteria that produces the biogas from the organic debris. The composition of biogas is main ly methane (60 to 70%) with lesser amount of carbon dioxide (30 to 40%) and traces of hydrogen and nitrogen. It is a colourless gas and burns in similar way as natural gas (it actually burns at 800 C compared to natural gas which burns at 1000 C, twain suitable for cooking and any other household application). A biogas plant consists of a brick made nderground chamber about 10 feet in bloom connected to a smaller surface feeding chamber on one side and a debris outlet chamber on the other side. Cow dung or other biomass material with water (in 11 ratio) are fed once a day into the underground chamber from the surface and biogas is generated and accumulated at the top part of the chamber. The gas is tapped by inserting a rubber pipe and supplied to kitchen or other places in the house. After producing gas, the residue is moved to the outlet chamber under the gas pressure and incoming new biomass materials and is deposited in a pit as a very good uality fertilizer ready to use in th e field. In Bangladesh about 44 million oodles of fuel wood is used in rural areas as cooking fuel each year (Islam and Islam, 2011). These destroy our forest and have negative impact on weather, land and environment. Also, as other biomasses like leaves, cow dung and agricultural residues are burnt as cooking fuel, these can no more help as a natural fertilizer as part of the cycle that detentions foliate 10 / 79 Journal of Chemical Engineering, IEB Vol. ChE. 26, no. 1, December 2011 the balance in the ecosystem. In all the above counts, use of biogas technology will bring about benefits to the nvironment and the people. It certainly upgrades an ageold ineffective and poor energy use practice into a more businesslike and scientific one. Improved Cooking Stove ICS are those traditional stoves upon which most modifications have been made to give higher thermal efficiencies. The efficiencies are delimitate as a fraction of heat content of the fuel fruitfully utilized. Improved stove save 50-60% traditional fuel as compared with traditional ones. Total amount of traditional fuel expenditure in the country is about 39 million tons annually. If improved stoves popularized in the country and if it saves 50% raditional fuel, then annually about 19. 5 million tons of traditional fuel will be saved. The reduction s of traditional fuels by improved stoves, therefore , have lower emission of colour house gases in the atmosphere. It as well as helps follow the forest alternatives of the country. In Bangladesh it will be difficult to supply natural gas for cooking drive to the every households of the country. Therefore, improved stoves have able future in the country. striking scale dissemination of improved stoves in the country can conserve the local forest and change the social life to a bully extent. Factors of SuccessRET is the technology of the Future. But unless this technology can reach the most deprived and vulnerable sort in the world today the millions of rural people who suffer most from the energy crisis this technology will neither reach its full potential, nor will the economic and social problems of the world be lick. In the early stage when very few POs started to promote renewable among the rural people, village electrification was considered the domain of government programs and development aid, leaving a lega cy of inefficiency and bony subsidies. Eventually some ripe financing scheme had been created to make RET ffordable for rural people. Innovative Financial Schemes to make the Technology Affordable at the same cost as Kerosene RET is still pricey relative to traditional energy sources. One of our initial challenges was to bring good deal the high upfront cost of a solar system. An innovative initiation base financial scheme worked fantastically which digestd the cost of a system to monthly ker osene cost. This is at the central core of our success story. It alike allowed us to expand our market an d reach economies of scale which further allowed us to bring down our costs per unit and engage in a profitable, sustainable business.Instead of renting, we strained on ownership which translates into better care and higher rank of the system. As the price of traditional energy sources rises, renewable energy technology is becoming more and more viable, especially due to its low per unit cost. But, the high upfront cost of the technology is still a major obstacle in generating the shift away from traditional fossil fuels and must be dealt with. condense on Em forcement, Income Generation & Cost Savings Tiding the technology with income generation, cost savings, higher standard of living, and especially social and efficient mandate is very important . In ruralBangladesh, solar exponent became synonymous with social status, better living and more income. A rural family could save up to BDT 700 per month in energy cost while enjoying televisions and other ultramodern amenities. Once the installments were paid off within 3 years, there was stripped-down running cost for nearly 20 years. This made solar a more attractive option than kerosene. They were social benefits withal. The burden of women were reduced as they no longer had to clean kerosene soot , work under dim light and they could allot part in home based income generating activities. Children could study under solar light and get connected o the outside world through televisions. For rural businesses, solar power meant productivity, more sales, income and jobs. A rural business could double its turnover by victimization solar while minimizing energy cost. Solar power especially helped improve connectivity, increase the sales of electronic goods, create new business opportunities such as mobile phones charging shops, electronics repair, maintenance shops, community television centers etc. A Strong Grassroots Network to let after sales service, right at the doorsteps of the rural people Rural pe ople are unbelievable to invest in a technology which s not long-lived and no after sales service is available. We focused on creating a vast network of rural engineers who developed one to one vibrancy with their customers. They visited each monthly to offer free after sales service for nearly 3 years. Long term warranty (i. e. 20 years for panels, 5 years for batteries and 3 years for charge controllers etc. ) for SHS sum buyback option under which a client can contribute his /her system, if the area becomes grid connected is a wonderful weapon to explore renewable in the rural areas. A rural network of women technicians has been created to collect and epair solar accessories to ensure low cost, quick effective repair, maintenance services and availability of spare parts, right at the door steps of the users. It also trained customers on how to take care of their systems and provides them with training manuals. This meant well unbroken systems, minimum repair and maintenanc e cost for both clients and us. Capitalizing on confederacy Forces One reason for this sector was the active involvement of the rural community. Rural people were completely unaware of renewable energy technologies. Winning rural confidence played a vital role. Engagement of community leadership and organizing emonstrations helped a lot. Special focus on creating local stake-hold social and economical was significant. In order to keep the goodwill, the POs offered special packages for rural schools and madrasa. Introduction to acquisition for school children of solar users and design of especial programs for rural school children to rootage awareness of renewable in the next generation were also done. quickness and maintenance the systems, Page 11 / 79 Journal of Chemical Engineering, IEB Vol. ChE. 26, No. 1, December 2011 understand the local market and customs were accelerated by the local youth. Setting up of village ased technology centers to assemble all solar accessories, creating jobs for local women was also essential. This bottom-down, decentralized approach has helped us to keep operating costs low, and gain acceptance by the local communities. GS was anomalous in that sense that GS not only provided clean energy solutions, but also created powerful social and economical forces for their adoption. For example, GS created jobs for young men and women who could create enough in few years to install a system themselves. A Listening Culture coupled with Strong Quality mince Building institutional capacityChallenges and Opportunities Fully developing the infrastructure for renewable in Bangladesh requires more than just putting solar systems on the market. Many projects in t he country also work to remove the barriers to more widespread use of renewable systems and build the skills along with the partner organizations. These POs help oneself a package of interventions to support Bangladeshi institutions in overcoming major market barriers. These institutions include rural electricity cooperatives, community-based organizations, NGOs, microfinance institutions, and private-sector groups. Women as Active agents of ChangeGS remain tuned to local needs by listening to our staffs and clients. The strong Audit and MIS system help GS seek new opportunities, meet challenges and forge ahead. We are flexible and localise in our approach, but without sacrificing quality. SHS registered exponential growth after the advent of IDCOL with the number of service providers, suppliers, manufactures multiplying. Bangladesh gained the capacity to manufacture all solar accessories expect for the solar panel. Our government has set a target of reaching all with electricity by 2020. Momentum has been created for solar power which our rural people have accepted whole eartedly. Solar & other renewable are in a position to play a very important role to complement government efforts to take electricity to all by 2020. We are as yet to reach the pene tration rate of mobile phones or televisions which has reached more than half portion of the rural market. We are yet to reach cost effectiveness to reach all rural income groups especially the lower income group in large numbers. Challenges GS has set up village based GTC to train and empower young women to become Renewable heftiness Technicians and Entrepreneurs. This was one of our most innovative and successful programs. These centers managed by omen engineers train rural women in renewable energy technology, enabling hundreds of rural women to sack extra money. These women who conk out to most deprived class of their communities have learnt skills on assembling, installing and repairing and maintaining one of the most up to date technologies in the world. They assemble and repair solar accessories such as charge controllers, mobile chargers, invertors etc. This has enhanced their social and economic value in their communities and contributed to women empowerment. These women have are the backbone of our local production and repair network helping rural people ccess cost effective, efficient services right at their door steps. They are powerful voices motivating other women, their families and neighbors to install solar and other renewable. Appropriate convergence Design & Diversification GS with other POs promote and design high quality, innovative products which meet the diversified needs of rural clients. The customer tailored packages ranging from 10 to 135 watts allow a rural client to save energy, generate income and become the owner of a system after 1 or 3 years, at the same cost of kerosene. The standard 50 watt system allows a rural client enjoy 4 bright lights, atch televisions and power mobile phones. For the lower income grouped, there are 10 to 20 watt systems and micro-utility model which al lows sharing of one system by many. Depending on the income of a rural client, the design products varies to power computers, DC fans, refrigerator s and income generating activities. Page 12 / 79 There are more than 30 organizations busy in the rural renewable energy sector. Expect for a few, bulk have a very small client base. Cutting butt against business culture is yet to develop in this field because of the prevalence of NGO culture. There has been very little incentive for nnovation or new product development because most of the organizations depend on guaranteed soft loans from IDCOL. salute practice of vast rural network of branches and engineers translates in huge feat cost and slow penetration rate. Lack of good communication especially during the rainy season constraints movements and increases transport cost. Seasonal variation in the income of the rural people makes collecti on of installment difficult. This is not cost effective or feasible in the long run. Training and retaining efficient human resource at the field level is also difficult. Incentive is low compared to the unstated work.It is difficult for organizations to increase incentives in order to keep their costs low. There is lack of skilled engineers who can make cost effective and efficient SHS designs especially for productive applications. Another major challenge is high battery prices and inability to source quality materials or accessories cost effectively. Huge appraise and VAT are charged on import of all raw materials except solar panels. This increases the cost of local manufacturing of Journal of Chemical Engineering, IEB Vol. ChE. 26, No. 1, December 2011 solar accessories which in turn increases the cost of Solar Home Systems. ould otherwise come from the fertilizer producing industries. By helping to counter deforestation and degradation caused by overusing ecosystems as sources of firewood and by melioration of soil conditions, biogas technology reduces CO2 releases from these processes and sustains the capability of forests and woodlands to act as a carbon sink. There has been very little incentives from the government to popularize RET except for long term soft loan through IDCOL. Most practitioners are over dependent on IDCOL with no diversification of funding. Mainstream financial institutions are yet to take a major interest in the RET sector.Improved Cooking Stoves can be one of the most cost effective devices to interference in -door air pollution and reduce deforestation. In this connection, GS has already constructed close to 373,969 ICSs through local technicians. A huge positive response from women have been receiving because of 50% less fuel cost and smoke free cooking. discordant POs could disseminate 10 million cooking stoves by 2015 if proper initiatives are taken . Opportunities Exponential demand has been created among rural people for solar power and renewables. This is mainly due to increased price of kerosene, diesel, and lack of grid connected ower, decreased price of solar energy, and especially due to growing aspiration and economic diversification of the rural people. Dependence on land or agriculture is reducing, cattle is being replaced by power tillers, tractors etc. virtually 60% of the rural people own a television. Diversification of rural economy concurrent with increasingly efficient solar systems has created market for large Solar Energy System applications to power pumps, mini/micro grids for SMEs, cyberspace kiosks etc. The rural farmers suffer from power shortage during the irrigation season and permutation of electric power pumps by solar pumps would save the rid system of 800 MW load on the national grid. There is also increasing demand in rural health and education sector for Integrated Energy Systems to power lights, computers, TVs and refrigerat ors etc. Solar power can fill the niche. Solar power can also be used for early ideal systems, emergency lighting, water desalination etc. in disaster zones. increase load shading in the urban areas has made solar power an attractive option for urban dwellers. 1 to 10 KW sys tems to power lights, TVs and other appliances in domestic and commercial sector can easily create a niche, alongside diesel generators and Instant PowerSupply etc. proficient progress has reduced cost, increased efficiency and diversified the application of solar energy. For example, use of conduct and CFL has reduced the cost of solar power, while increasing its efficiency. Pico systems (1 to 5 watts) can power 2 or more lights while charging mobile phones. This has brought solar technology within the reach of lower income groups. LED based systems have resulted in dramatic decrease in costs. Factors to reduce cost include efficient loads, innovative batteries, and lower module cost. We can use biogas technology not only generating cooking gas, but also for generating ure methane gas which can used for running vehicles, power pumps and other electronic equipment. This will facilitate rural development. Though some large s ized biogas plants in Bangladesh are generating electrici ty, needs. We can scale this up if we can sublimate the gas and place it in cylinders. We can use all types of wastes ranging from animal dung to crop resi dues for this purpose. This is successful technology which has been implemented in India, Sweden and many other countries. Our presidency which is promoting independent power generation should also facilitate this type of technology. We can use biogas technology in urban areas to onvert wastes into electricity, gas and organic fertilizers. Again Biogas technology takes part in the global splutter against the greenhouse effect by reducing the release of CO2 from ardent fossil fuels in two ways. First, biogas is a direct substitute for gas or coal for cooking, heating, electricity generation and lighting. Second, the reduction in the consumption of artificial fertilizer avoids carbon dioxide emissions that Bangladesh currently has a thriving RET sector with multiple companies manufacturing batteries, lightings and other solar a ccessories. Many of these companies are also tradeing heir products. Recently government has decided to include solar as a thrust sector in its industry policy. indemnity Options Building a Cutting Edge Entrepreneur Based organize Bangladesh is uniquely positioned to reach 75 million people with renewable energy technologies by 2015. However, we cannot tap into this huge potential through the existing model. We need to develop a cutting edge, efficient, flexible structure of rural based entrepreneurs who will take solar and other RET to every quoin and corner of country to create a truly Solar Bangladesh. We need to focus on the following for the above transformationCreating Clean Energy Entrepreneurs Page 13 / 79 Journal of Chemical Engineering, IEB Vol. ChE. 26, No. 1, December 2011 Providing long term soft loans at 5 to 6 % interest rate to all RET related businesses is necessitate. Present practice is that service providers can access soft loans after installing the systems . This does not take into account high upfront cost of sourcing supplies or developing the organizations. in addition solar related manufacturing/ supply companies have to access loans at very high cost. Our financial incentives are focused on microfinance institutions. Instead of this, we should help create business companies small nd big at the rule/sub-district level linked with local entrepreneurs to widespread RET. This would create ownership, innovations and competition. We can create village based women entrepreneurs to promote Improved Cooking Stoves etc. They would also assemble, repair solar accessories and provide after sales service. They can be linked with small faith from rural financial institutions. RET is a step in the right direction. However most clients / renewable energy companies have been unable to access the loan because loan is to be provided to SHS customers and reimbursement is only after the installation.Energy Companies are not able to directly access this fund. This financing scheme has failed to gain momentum because of complex regulations and risk adverse drift of commercial banks. We can create village based SME entrepreneurs to popularize sol ar pumps, mini grids and biogas plants etc. The entrepreneurs would invest in the technology and earn a return by renting the technology to others. They can source loans from rural banks. District/sub district level companies can help rural based source loans and the technology through guarantee, information, while national level companies would help istrict/sub-district level small and big compani es to source finance, technology and build up their market. Including a component in hold loans for installing solar. Creating a special green fund for providing grant for vaporize testing new projects. Providing matching grants through local government institutions to green our infrastructure such as rural schools , clinics, cyclone shelters, etc. Focusing on an Efficient, Cost effective Supply Chain We need to set up more battery and other solar accessory manufacturing units to create a competitive environment, reduce costs and increase efficiency. Our government should try o attract foreign investment and R & D in this sector. Creating a window in agricultural and other rural financial institutions to provide credit fo r RET, we can include training and credit for renewable energy technologies in our youth development programs. We should especially focus on SME loans and micro-credit loans for creating small and big entrepreneurs in the rural areas. Currently solar practitioners are suffering from high battery price. This can be solved through more battery companies. We should concentrate on manufacturin g export quality products to achieve economies of scale and tap into the world market. We can onsider background up unfledged Enterprise Zones especially for solar accessories such as charge controllers, invertors, mobile chargers etc with a focus on the rural areas to create green jobs. Circulating green bonds for raising capital for solar and other RET. Passing Pro -renewable energy Laws Providing special incentives such as long term soft loans, tax cuts for promoting solar both at the individual and commercial level. Biogas production can also be installed in compounding with sanitation. Public toilets incorporating biogas units are particularly suitable for pen -urban areas and small towns in India where the supply of cooking gas is nadequate and wastewater treatment is unaffordable for the local authorities. Biogas systems can become part of decentralized wastewater treatment, and provide the fuel needed for heating water, for bathing and running generators to provide lighting in these facilities. Removing all VAT/Tax for all type of solar accessories and raw materials to reduce cost. Bangladesh has one of the highest tariff structures in the world. Providing tax holidays and other benefits for investing in solar businesses. Making it mandatory to have all market places, restaurants, commercial buildings to install solar. At the same time government should rovide soft loans for solar installation which would be part of housing loans. Easy Access to Green Credit & Funds Investing in Capacity Development and R & D Page 14 / 79 Journal of Chemical Engineering, IEB Vol. ChE. 26, No. 1, December 2011 Developing a sustainable framework for developing human resources through country wide vocational centers, training institutes etc. Focus should be also on developing export quality human resource. This would also an incentive for private companies to participate with the maturing of the sector. Focusing on R & D to adapt and develop innovative technologies. We should have nnovation lab in all major universities which should be linked with international institutions and research institutions. Government should create an incentive structure such as competitions, awards to promote R & D. Facilitating new ideas such as in stallment collection through mobile phones, prepaid cards to scale up and reduce transaction costs. inference Bangladesh has given birth to one of most successful models to replicate RET. Keys to these successes are an innovative credit system, appropriate product design, grassroots based effective and efficient after sales service plus other consumer kind options. However, the main actor behind the Bangladesh success story is that it empowers rural communities to own and uses RET and eventually become partners to bring and expand RET in their communities. It seeks solutions that empower women, the disadvantaged, create jobs, facilitate rural development and especially protect the environment. To summarize, Bangladesh already has experience with RET projects. The potential of these project initiatives is high. Viable approaches need to be amplified to a broader context under a national RET strategy. In particular, the pilot schemes of RET development in Bangladesh need be scaled u p to take a greater share in f niche markets for RET and strengthening relevant institutions to implement RET policy direction are possible avenues to assist with this.
