Renewable Energy Scenario in Bangladesh

Renewable and Sustainable Energy Reviews, 2014

Energy is the building block of modern civilization and a prerequisite for sustainable development. Global energy consumption will increase by 36% with an annual growth of 1.6% from year 2011 to 2030, comprising 88% fossil fuel share. Bangladesh is a developing country in the Southeast Asia, which is one of the lowest per capital energy consuming nation. The power crisis has become a major constraint to continued economic growth and energy sector of the country is currently facing serious challenge. Due to depleting nature and mono fuel dependent energy policy; finding alternative energy source has become imperative for the country. This study examined the current energy mix, present energy crisis and its way to overcome such scenario by utilizing alternative energy sources such as biomass, solar, wind and small scale hydropower energy, in the context of Bangladesh. Among the renewable energy sources, biomass is found to be the most effective and utilizable. Potential electricity generation from biomass is 312.608 terawatt hour (TWh), where only 44.52 TWh is utilized. On the other hand, solar home system (SHS) has shown positive impact on socioeconomic development in the rural areas by alleviating poverty and creating jobs. To assure national energy security, and aiming to provide constant and quality power supply to all citizens of Bangladesh, Government of People's Republic of Bangladesh (GOB) must strive to double its effort towards attaining greater renewable energy share by conversion, utilization and dissemination.

This paper reviews the prospects of available renewable energy resources along with various private and government future project plans to incorporate renewable energy sources and their potentials as per context of Bangladesh. According to the approved renewable energy policy, the Government of Bangladesh (GOB) is devoted to facilitating investment in both public and private sectors in renewable energy projects to substitute contemporaneous non-renewable energy resources and to escalate the contributions of renewable energy based electricity generation. A plan has been initiated by the GOB to generate 5% of the total energy from renewable energy resources within 2015 and 20% by the year 2020. The aim of this paper is to provide an overview of the present condition of renewable energy resources in Bangladesh and hence, different types of renewable energies are discussed from global perspective to achieve a clear perception about solving the power crisis issues in Bangladesh with this sustainable approach.

A developing country such as Bangladesh, where economic development without compromising the eco-friendly environment is a burning issue, needs huge supply of power. Having very limited fossil fuels, sources of renewable energy such as solar, wind, biomass and limited hydro power are the probable alternatives to offset energy crisis in Bangladesh and similar other countries. Over three-quarters (76 percent) of Bangladeshi people are out of on-grid connected electrical power supply. Undeniably, it has limited natural gas being used for a large variety of purposes. Energy demand is estimated to increase exponentially, implying alarming supply and demand gap. Despite prospects of huge renewable energy sources, presently, this country has only 0.3 percent of renewable energy share to the total energy supply. This paper reviews the renewable energy status and its prospective use in Bangladesh as well as renewable energy technologies obtainable in Bangladesh. It also attempts to provide future research directions and show ways to harness renewable energies to meet the future demand.

— A majority of the people around the world are largely dependent upon fossil fuels like oil, natural gas, and coal on fulfilling their energy needs. It is necessary to find alternative energy sources as the fuels will be depleted within a certain period of time due to its limited reserve. Renewable energy is a sustainable energy source that will play a pivotal role in full filing the ever increasing energy demand. As it is clean energy and does not emit any hazardous gas or materials to the environment, it is likely to be the preferable energy source to provide energy and environmental security. Bangladesh is a developing country and it is facing difficulties in supplying energy to maintain its economic growth as well as sustainable development. Though Bangladesh has a very negligible carbon footprint, but it is one of the most vulnerable nations in the world for the effect of climate change. Renewable energy can be the only option which can reduce the associated risks. This review article studies different sources of renewable sources in Bangladesh and possibilities of contributing to meet the energy crisis. This study also provides a synopsis of present scenario and initiatives that are taken by different governmental and nongovernmental organizations to promote the generation and use of renewable energy.

Renewable Energy Technologies (RETs) have become multi-billion dollar industry from the realm of laboratories in recent years. Installed capacity of non-hydro RETs is already 60,000 MW [GEF 2001] and at present they are supplying 14 percent of the total global energy demand [WEA 2000]. The World Energy

Energy is one of the indispensable inputs for the survival of human being in the earth. Bangladesh has the very inadequate amount of indigenous non-renewable energy resources even which is being diminishing rapidly to increase the electricity generation. Although the installed electricity generation capacity has been increased to 10907 MW, still the amount is insufficient to meet the demand of the country. In addition to this, the insufficient power generation hinders the socio-economic and industrial development. This current problem in power generation of Bangladesh can be removed by incorporating renewable energy into electricity generation. Recently, utilization of renewable energy and Renewable Energy Technologies (RETs) are getting momentum in the country to achieve not only energy security but to reduce environmental pollution and to limit the imminent depletion of the non-renewable energy resources. Overall, Bangladesh has the vast potential of biomass, solar, hydro, wind, and tidal powers. This paper outlines the present energy scenario of the country. Following this, the potential of available renewable energy resources is also reviewed and presented in this paper. Key words: Energy crisis; Renewable energy; RETs; Bangladesh.

District heating networks are commonly addressed in the literature as one of the most effective solutions for decreasing the greenhouse gas emissions from the building sector. These systems require high investments which are returned through the heat sales. Due to the changed climate conditions and building renovation policies, heat demand in the future could decrease, prolonging the investment return period. The main scope of this paper is to assess the feasibility of using the heat demand-outdoor temperature function for heat demand forecast. The district of Alvalade, located in Lisbon (Portugal), was used as a case study. The district is consisted of 665 buildings that vary in both construction period and typology. Three weather scenarios (low, medium, high) and three district renovation scenarios were developed (shallow, intermediate, deep). To estimate the error, obtained heat demand values were compared with results from a dynamic heat demand model, previously developed and validated by the authors. The results showed that when only weather change is considered, the margin of error could be acceptable for some applications (the error in annual demand was lower than 20% for all weather scenarios considered). However, after introducing renovation scenarios, the error value increased up to 59.5% (depending on the weather and renovation scenarios combination considered). The value of slope coefficient increased on average within the range of 3.8% up to 8% per decade, that corresponds to the decrease in the number of heating hours of 22-139h during the heating season (depending on the combination of weather and renovation scenarios considered). On the other hand, function intercept increased for 7.8-12.7% per decade (depending on the coupled scenarios). The values suggested could be used to modify the function parameters for the scenarios considered, and improve the accuracy of heat demand estimations. Abstract Global energy demand has risen sharply over the years with developing countries recording the greatest share in this trend. Biomass as an energy resource is mostly available locally and can easily be converted into secondary energy without huge capital investments. Nowadays, Bangladesh shares a percentage of renewable energy only 3% of total energy ratio, Bangladesh has already taken a master plan in the renewable energy sector. Whereas installed electricity generation installed capacity of Bangladesh rapidly increased to 13265 MW with captive generation capacity which is insufficient for fulfilling the demand of electricity of the nations. One-third of the power production of Bangladesh depends on expensive imported fossil fuel energy resources and 65% of power generation depends on a natural gas reserve of the country, though one day the reserve of current gas will be diminished. Moreover, inadequate electricity production leads the country in a un-industrialization. The present and future crucial energy crisis situation adapted by installing renewable power into electricity production. The current renewable energy agenda of Bangladeshi government force the specialization of renewable energy generation budget by decreasing global pollution with saving movement of biomass, solar, hydro, wind, and tidal power sector. This paper presents the currents national energy scenario of Bangladesh. According to this, the greater potentiality of renewable energy resources is also reviewed and presented in this paper.

Deficiency in energy sector is a major problem, which can hinder the development workflow of any country. Being the eighth most populated country in the world with a total electricity generation of only about 5000 MW and consumption of 146 kWh per capita, Bangladesh is one of the most electricity-deprived countries around the globe. In addition, absence of adequate investment and mass people awareness is a major problem in this country. Therefore, it would be very difficult to achieve overall progress without ensuring energy security by utilizing the promising renewable energy sources. In order to achieve the Millennium Development Goal (MDG), it is must for a third world country like Bangladesh to address the issue of energy deficiency promptly. In this context, renewable energy is the sustainable solution of energy security as well as social, environmental and economical problems. This paper summarizes the current energy scenario of Bangladesh, impacts of pollution from conventional energy sources, prospects of renewable energy development, and estimates the total investment required in Bangladesh to promote renewable energy sector by the year 2020.
