Sufficient energy supply capability is the key factor for the development of any country. Present world is mostly depended on natural resources for energy production. But as the amount of natural sources of energy are declining day by day, to meet the increasing power demand with the renewable energy sources are becoming important. This issue is important for country like Bangladesh as it faces high...
This paper signifies a method of development of a forced draft biomass cook stove for off-grid rural areas where the technology of thermoelectric generator has been implemented for electricity generation. The thermoelectric generator is a semiconductor device that converts heat energy directly to electrical energy. The thermoelectric generator is positioned on outer wall of the cook stove's combustion...
Energy challenges of today include increasing energy dependency, growing energy consumption, ensuring security of energy supply, reaching for sustainable development and tackling environmental concerns, most importantly climate change. Bangladesh is one of the low energy consuming countries of the world. Still the national grid can so far cover 49% of the total population. Renewable energy sources...
Fossil energy is a major problem that disturbs the world. So replacing this kind of energy with another cheapest, harmless and that last forever become a strategic question. A big question still running the minds of the workers and investors in this sector, which type of renewable energy we should apply? At which cost? What will be the payback period and the return on investment? The aim of this paper...
With the increasing demand for energy, dwindling oil reserves and global warming, the current fossil fuel based mechanical power and electricity has caused severe environmental degradation and energy shortage. Renewable, non-polluting and biodegradable energy sources must be adopted. Producing biodiesel from algae which represents the third bio-energy feedstock appears to be the most straightforward...
Seawater samples were collected from various locations along the Lebanese coast. Four unilagal isolates were acquired using streaking and serial dilution methods. The four isolates were cultured in 20 L flat photo-bioreactors containing seawater fertilized with Guillards F/2 medium. The growth dynamics, dry matter yield, lipid content, fatty acid profile and potential biodiesel yield were determined...
The serious issue of power shortages in developing countries like Pakistan leads to the search for developing renewable, economical and environment friendly re.sources of energy. Generating electricity through Waste To Energy (WTE) Plants can be a good choice for densely populated cities and is becoming popular in Asia as an economical and environment friendly technology. In this paper, capacity of...
This review describes the biomass, which categorize as liquid, from industry or farming. Its advantages make biomass and biological process more environment friendly and less energy intensive as compared to thermo-chemical and electrochemical processes. Unfortunately, research and application of biomass are yet in their infancy and suffer from large scale because of low productivity. Reviewing the...
The upcoming shortage of fossil fuels and the environmental threat of global climate change has led mankind to search for alternatives concerning its energy supply. Today, enormous efforts are made to maximize the productivity of biomass and identify new species of plants and processes to accomplish the future demand of food, fodder, materials and energy. Biofuels play a crucial role in mitigating...
Electrification can bring about many changes which would improve living conditions of the population. However, electrification would also put a strain on the national energy supply; thus, it should be implemented in a sustainable manner. This study employs the Long-range Energy Alternatives Planning (LEAP) model to analyze future energy demand, investment costs, and CO2 emissions of three scenarios...
Renewable Energy (RE) based on town concept in Iskandar Malaysia (IM) that can serve as a global model for a smart eco — village in tropical countries is proposed. In this research, renewable energy (RE) based distributed energy generation (DEG) system for Kulai eco-village (KEV) driven by integrating of biomass, biogas and solar energy. Thus, this paper discusses RE supply and demand side estimation...
Conventional grid extension has been the predominant mode of electrification in India. However, renewable energy based mini-grids have also been used for providing electricity access in remote areas, forested habitations, and islands. This paper, based on extensive literature review, interview with key stakeholders, and field visits to selected sites, captures the nuances of renewable energy based...
The National Action Plan for Climate Change of India considers renewable energy as a key thrust area. This paper focuses on one such renewable energy source, bioenergy which exists in diverse forms and finds applications in varied energy supply and demand sectors. Two long term scenarios for bioenergy up to 2050, business-as-usual (BAU) and green energy (GE) are assessed using a bottom up energy system...
This paper stresses the need for adapting a sustainable energy planning concept, which can support the implementation of renewable energy in developing countries; exemplified by a Vietnamese case. Many developing countries heavily rely on fossil fuel resources and will face energy supply security challenges in the future. At the same time their policies on renewable energy, tools and action plans...
Energy demand and environmental impact are the main driving force for alternative energy sources. Indonesia and Malaysia are the most developing ASEAN countries where the palm oil is one of the most revenue earning sectors. Oil palm plantation not only produces crude palm oil (CPO) but also a huge amount of biomass residues such as palm oil EFB, palm oil shells and fibres. Palm Empty fruit bunches...
United States renewable energy businesses require well trained high school and college students to fill key positions as technicians, engineers, and other high paying jobs. Project based learning programs offer a way to train students in these emerging fields with realistic, intensive student-designed and built projects. This paper reviews the challenges and some of the lessons learned in developing...
Pakistan is facing severe economic crises due to continuous increasing gap between energy demand and supply. Demand is increasing exponentially and expected to increase more than 66000 MW by 2030 while the supply is observed to remain constant over the last few years due to frozen capacity in spite of having significant renewable/alternate energy resources. Current electricity shortfall has reached...
While other neighboring countries are emerging with strong economic growth, Bangladesh, in spite of having abundant resources, is still struggling with power shortage. Energy-starved Bangladesh is facing daunting challenges to meet projected demands for electricity that will exceed domestic supply capabilities within a few years. With only 49% of Bangladeshis having access to electricity, the per...

This paper presents an approach that could be adopted as part of electrification strategies in developing countries. It makes use of microgrid designs which can be expanded and replicated in a modular fashion across wide geographic areas. The process of designing such a system is demonstrated with a case study in the state of Bihar in India. Results from the case study allow the costs of electrification...
