Renewable Energy Development

In Bangladesh, annual per capita energy consumption is approximately 200 KgOE3, which is among the lowest in the world. Presently, 70% of the population does not have access to electricity in Bangladesh (GoB, 2004). The average system loss is 20.97% (GoB, 2006). The demand for power is estimated to increase 300 MW annually (GoB, 1996a). In contrast, concerns have been raised about the conventional energy production from fossil fuels that significantly contributes to environmental degradation at the local, regional and global levels. This situation calls for adoption of sustainable energy strategies that permeate every level of the economy and can provide rural dwellers with the services that they want and need. With this backdrop, Bangladesh has been experiencing a gradual shift towards exploring renewable energy resources as a means to fuel rural development in the off-grid areas. The country is endowed with abundant renewable energy resources. The Local Government Engineering Department (LGED), with its mandate for sustainable rural development has embarked on a program for demonstration and transfer of renewable energy technologies in the off-grid rural areas. The project “Sustainable Rural Energy (SRE)‘ has been conceived within the overall framework of ‘Sustainable Environment Management Programme (SEMP)’ with financial support from United Nations Development Programme (UNDP). This project has already completed a number of renewable energy installations demonstrating diversified community applications of these technologies for livelihood and socio-economic improvement of the people living in the remote off-grid villages. The lessons learned from these demonstration plants reveal that, with careful forward planning, renewable energy can provide far-reaching economic and social benefits to people living in remote rural areas in Bangladesh. The private sectors and NGOs (Non-government organizations) have started to take part in the process of renewable energy development with great promise and enthusiasm. However, the process encounters policy, institutional and technological barriers, which are critical for continued development in this sector.

Important Means

Solar energy is now a very important means of renewable energy resources. With sun tracking, it is more effective to produce more energy because solar panels can maintain a profile perpendicular to sunlight. Although the initial cost of setting up a tracking system is quite high, there are cheaper options that have been proposed from time to time. Light Dependent Resistors (LDRs) are used to detect sunlight. The solar panel is positioned where it can receive maximum light. Compared to other motors, servo motors are able to maintain torque at high speed. The tracker is in the form of a double or single axis. Dual trackers are more efficient because they track sunlight from both axes. This project is designed for low power and portable applications. Therefore, it is suitable for use in rural areas. In addition, the effectiveness of the output power collected by sunlight increases.

The World

Renewable energy has received noteworthy attention during the last few decades. This is partly due to the fact that fossil fuels are depleting and the need for energy is soaring because of the growing population of the world. This paper attempts to provide an idea of what is being done by researchers in remote sensing and geographical information system (GIS) field for exploring the renewable energy resources in order to get to a more sustainable future. Several studies related to renewable energy resources viz. geothermal energy, wind energy, hydropower, biomass, and solar energy, have been considered in this paper. The focus of this review paper is on exploring how remote sensing and GIS-based techniques have been beneficial in exploring optimal locations for renewable energy resources. Several case studies from different parts of the world which use such techniques in exploring renewable energy resource sites of different kinds have also been included in this paper. Though each of the remote sensing and GIS techniques used for exploration of renewable energy resources seems to efficiently sell itself in being the most effective among others, it is important to keep in mind that in actuality, a combination of different techniques is more efficient for the task. Throughout the paper, many issues relating to the use of remote sensing and GIS for renewable energy are examined from both current and future perspectives and potential solutions are suggested. The authors believe that the conclusions and recommendations drawn from the case studies and the literature reviewed in the present study will be valuable to renewable energy scientists and policymakers.

This paper aims to address the issues related to renewable energy (RE) resources optimization at rural areas. A transportation algorithm is proposed in order to optimize the utilization of renewable energy and allocate various renewable energy resources to different demand stations. A rural area in Sarawak, Malaysia is selected as a pilot area for implementing the proposed method. The total annual energy demand for the pilot research area is 860,567.12 kWh, while the annual renewable energy potentially available is 879,419.48 kWh. The simulation results of this transportation model reflect that although there is a potential for solar and wind energy at the selected rural area, the model has selected hydropower and biomass as a more viable option. The results obtained from the proposed transportation model have been verified with the results of other RE studies. It is proven that the developed model could be used as a decision making tool to evaluate application of various alternative renewable energy resources and to determine the optimal location for development of these resources.

Climate And Energy Policy

The main objective of the article is to identify the implications of implementing climate and energy policy for rural areas.Due to their quantitative and qualitative potential, rural areas participate to a significant degree in the achievement of the indicative targets resulting from the climatic package. Thanks to the production of biomass and, increasingly often, energy itself during the 2006-2016 period, the share of RES (renewable energy sources) in the production of primary energy grew twofold from 7.8% to 13.9%. Biomass was the main source, but since 2010 the use of wind and sun in the production of energy has been growing rapidly. Based on the analysis, it can be argued that by 2050 most of the energy and renewable energy resources will be produced in agriculture and rural areas. Implementing the commitments stemming from EU climate and energy policy can be an impetus for rural development.

Use of renewable energies in rural areas in the island of Crete, Greece has been investigated. Crete has rich indigenous renewable energy resources which are currently utilized for covering part of its energy requirements. Various renewable energy technologies used for heat and electricity generation in the island have been examined. Solar energy, wind energy, hydro power, biomass, and low enthalpy geothermal energy are already used. The total installed electric power of renewable energies in Crete, located mostly in rural areas, is approximately at 30% of the total electric power installed. They currently generate more than 20% of the island’s annual electricity needs. More renewable energy applications are foreseen in the future in rural areas in Crete as soon as its electric grid will be interconnected with the country’s continental grid. New renewable energy technologies, which are not currently used, could generate in the future heat, cooling, electricity, and vehicle’s fuels in the island. Their use will have positive impacts including the promotion of energy investments, lower use of imported and polluting fossil fuels, de-carbonization of the island’s energy sector as well as creation of new local jobs. It is indicated that the rich renewable energy resources in Crete could provide almost all of its annual energy needs. This will result in Crete’s transformation to a low or zero carbon economy in accordance with EU targets for zero carbon emissions in the next decades complying with the global goal for climate change mitigation.
