孟加拉国拥有丰富的可再生能源。在各种可再生能源中，太阳能和生物质能，以及在有限范围内，风能和水力得到有效利用。本文对这些资源的有效利用进行了探讨。孟加拉国的平均日太阳辐射为4-6.5千瓦时/米(2)。太阳能光伏发电（PV）在向电网覆盖的偏远农村地区的家庭和小型企业供电方面正在获得越来越多的认可。根据“农村电气化和可再生能源发展（rred）计划”，到2007年将总共安装64,000台小水电。到目前为止，该国共安装了37,000台容量约为2.5兆瓦的SHSs。下一个有效的可再生能源是生物质能。在这一类别下，改良炉、沼气厂和生物质烧结炉值得注意。燃料研究与开发研究所（IFRD）开发了一些改进的炉具。与传统炉灶相比，这些炉灶节省了50-70%的燃料。到目前为止，已经在用户厨房安装了10万多个炉子。沼气技术的潜力是巨大的。据官方估计，牛的数量为2400万，家禽的数量为7500万。这可以产生大约30亿立方米的沼气。当地政府工程部（LGED）和IFRD正在努力在农村地区安装沼气厂。到目前为止，总共安装了19,596个沼气厂。库尔纳工程技术大学（KUET）在SIDA的资助下成功地开展了生物质成型技术的研究和开发工作。到目前为止，这项技术已经转移到私营企业家手中。目前，约有60家小型私营企业利用稻壳和锯末生产压块。由于地势平坦，水电资源并不丰富。目前，Kaptai大坝的发电量为230兆瓦。此外，在东南丘陵地区还发现了几个微水力点。最近，LGED在吉大港的Bamerchara安装了一个10千瓦的微型水力发电厂。除了孟加拉国的沿海地区，风能的潜力并不令人鼓舞。已经安装了一些风力涡轮机作为示范装置。LGED (c) 2005爱思唯尔有限公司正在进行一个国家风力测绘项目。版权所有。
Bangladesh is endowed with plentiful supply of renewable sources of energy. Out of the various renewable sources, solar and biomass and to a limited extend, wind and hydro-power are effectively used. This paper, discusses the effective applications of these resources. Bangladesh receives an average daily solar radiation of 4-6.5 kWh/m(2). Solar photovoltaic (PV) are gaining acceptance for providing electricity to households and small business enterprises in grid remote rural areas. Under the 'Rural Electrification and Renewable Energy Development (RERED) Programme' a total of 64,000 SHSs will be installed by 2007. So far, a total of 37,000 SHSs with a capacity of about 2.5 MWp have been installed in the country.The next effective source of renewable energy is biomass. Under this category improved stoves, bio-gas plant and bio-mass briquitting are note worthy. The Institute of Fuel Research and Development (IFRD) has developed a number of improved stoves. These stoves save 50-70% fuel as compared to the traditional ones. So far, more than 100,000 stoves have been installed in the users kitchens. The potential of biogas technology is immense. According to an official estimates there is a cattle population of 24 million and poultry population of 75 million. This can produce about 3 billion m 3 biogas. The Local Government Engineering Department (LGED) and IFRD are working to install the biogas plants in the rural areas. So far, a total of 19,596 biogas plants have been installed. Khulna University of Engineering and Technology (KUET) has successfully under took a research and development work on biomass briquitting technology with a grant from SIDA. By now, this technology has transferred to private entrepreneurs. Currently, about 60 small private enterprises are producing briquettes from rice husk and saw dust.Because the country is flat, hydropower is not abundant. At present, 230 MW is harnessed from the Kaptai dam. Besides, in the southeastern hilly regions a few micro-hydro sites have been identified. Very recently, one 10 kW micro-hydro plant has been installed by LGED at Bamerchara in Chittagong.Wind energy potential is not encouraging except in the coastal areas of Bangladesh. A few wind turbines have been installed as demonstration units. A project is going on for wind mapping of the country by LGED (c) 2005 Elsevier Ltd. All rights reserved.
