Energy plays a crucial role in human life as it is necessary for survival and enables us to perform daily activities. The passage of time has driven progress, with various tools, machines, and devices created to facilitate human affairs. Everything is very dependent on Energy. Unfortunately, the prevalent reliance on fossil fuels as the primary energy source has resulted in an environmental disparity attributed to greenhouse gas emissions. Besides, the depletion of fossil fuel reserves is a long-term concern for nations involved in fossil fuel production including Malaysia, which necessitates a delicate equilibrium between escalating energy demands and escalating pollution levels. This review paper aims to highlight the potential of renewable energy based on green hydrogen in Malaysia. The energy scenario in Malaysia has been reviewed by discussing energy demand, current population, energy policy synopsis, conventional energy sources, carbon emissions, and the direction of renewable energy in Malaysia. Besides, the conceptual framework for hydrogen as renewable energy was discussed covering the hydrogen economy, production technology, storage, and energy production using green hydrogen. Finally, potential applications for using hydrogen energy have been presented so that the future direction of using this alternative energy can be well planned in Malaysia. •An overview of hydrogen energy as Malaysian alternative energy is comprehensively discussed. •The hydrogen energy prospects are described in detail such as hydrogen economy, production, and consumption. •The progress of hydrogen energy implementation in Malaysia is studied towards embarking on this effort.

Sustainable development has many dimensions, such as clean energy, green growth, and sustainable industry. Green finance has a key role in realizing these targets. The core focus of the existing paper is to demystify the influences of green finance, green energy on environmental dynamics in Malaysia covering the timeframe from 1990 to 2018. To this end, we employ the QARDL technique to peruse the effect of green finance, renewable energy, and economic growth on CO 2 emissions and ecological footprint separately. By doing so, we crosscheck the empirical outcomes and inspect the consistency of the analysis. Firstly, empirical results show that the ecological footprint model yields similar results to the CO 2 emissions model in terms of statistically significant quantile ranges and the magnitude of the coefficients. According to the overall results, GDP increases environmental degradation while green finance and renewable energy have a mitigating role. Finally, we confirm a significant EKC hypothesis for Malaysia. Based on these findings, we recommend Malaysian policymakers focus on energy efficiency, realize financial reforms and promote green energy through the financial system to achieve the 2050 net-zero emission target.

Advancements in space technology have enabled the acquisition of reliable marine data, facilitating research on the potential of ocean renewable energy as an alternative source that can reduce dependency on fossil fuels, subsequently mitigating climate change. However, the ocean renewable energy development in Malaysia has not received adequate attention from local authorities and communities due to low resources in this area. Insufficient in-situ data, both in spatial and temporal dimensions, poses challenges in investigating the characteristics of ocean parameters, hindering a thorough study of the potential for ocean renewable energy development. Hence, this paper aims to identify potential ocean renewable energy development locations using the altimetry data and spatial-temporal clustering using the K-means technique. Theoretically, Malaysian seas are suitable for harnessing wind and waves with energy density ranges of up to 104.69 kW/m2 and 4.21 kW/m, respectively. This study enhances the understanding of Malaysian potential for ocean renewable energy, providing valuable information to stakeholders and the government to increase their interest in ocean renewable energy as a sustainable source for electricity generation in the future.

• The output power is conducted using 3D-PV model. • A new fusion of improved bi-archive multi-objective optimization algorithm is proposed. • A new hybrid MCDM method is considered to choose the most desirable configuration. • An accurate hybrid numerical method is used for validation of the proposed method. • Performance of optimum designs are evaluated for both cases: Malaysia and South Africa. Photovoltaic (PV) and Wind turbine (WT) systems are the most promising options for rural energy delivery. In the literature, numerous studies have simply considered only on economic efficiency, while maximizing dependability by a constant value for the given demand load. Moreover, a single set Pareto optimal front (PF) has been attained for the multi-objective optimization problem. Furthermore, the primary challenge of various the off-grid multiple renewable energy sources is excessive energy loss, resulting over/under sizing and a highly total cost for the system. Therefore, this paper presents a unique improved bi-archive approach to develop the diversity and convergence independently in order to find four optimum sets of PF solutions. In addition, a new integration based on best worst method (BWM) and preference ranking organization for enrichment evaluations (PROMETHEE II) method along with group decision making (GDM) mechanism are addressed to sort and rank the optimal sets PF solutions with full consistency ratios of the three experts opinions and high degree of stability in ranking configurations. The theoretical results based on actual hourly meteorological data in Malaysia and South Africa indicated that the suggested improved two-archive-BWM- PROMETHEE II-GDM method is not only able to construct a uniform set of Pareto optimal solutions with fast convergence and high diversity, but can also rank and select the most desired design for the PV/WT/Battery system. The optimum configurations of the two cases studies are composed of a single WT, 105 PV modules, and 69 batteries storages at zero LLP, 60185 ($) of LLC, and 13548018 (KWh) of P dump for Malaysia case study, meanwhile it composes of 16 WTs, 80 PV modules, and 69 batteries storage at zero of LLP, 66073 ($) of LCC, and 31371 (KWh) of P dump. The proposed standalone hybrid renewable energy sources system is verified and assessed in a comparison with existing hybrid methods in terms of increasing the reliability, lowering overall cost, and reducing wasted energy.

Small scale hydropower is one of the technology options to generate and supply electricity to grid off and rural applications with almost zero emission. Malaysia is blessed with abundance of water sources and receives high rain volume per year which can be used to generate power. This paper is carried out to present the potential of small scale hydropower in Malaysia and its current status at low head location and rural electrification. Moreover, the relevant research literatures for small scale hydropower technology and the challenges facing by small renewable energy power in Malaysia are also reviewed. The review of available works display that the estimated hydropower resources in Malaysia are registered to be 29,000 MW, of which 500 MW is from small (mini)-hydro power. For this, a total of 149 sites for small hydropower potential have been identified in the country and the expected potential by 2020 is 490 MW. Despite hydro-power technologies are preferable choices for energy generation in Malaysia, they have not been fully exploited yet due to some technical, economical, and institutional challenges. Therefore, this paper can provide information for further investigations on the application of small scale hydropower for rural electrification in Malaysia. [ABSTRACT FROM AUTHOR]

Synthesis gas, also known as syngas, produced from biomass materials has been identified as a potential source of renewable energy. Syngas is mainly consists of CO and H 2 , which can be used directly as fuel source for power generation and transport fuel, as well as feedstock for chemical production. Syngas is produced through biomass gasification process that converts solids to gas phase via thermochemical conversion reactions. This paper critically reviews the type of gasifiers that have been used for biomass gasification, including fixed bed, fluidized bed, entrained flow and transport reactor types. The advantages and limitations of these gasifiers are compared, followed by discussion on the key parameters that are critical for the optimum production of syngas. Depending on the biomass feedstock, the properties and characteristics of syngas produced can be varied. It is thus essential to thoroughly characterise the properties of biomass to understand the limitations in order to identify the suitable methods for gasification. This paper later focuses on a specific biomass – oil palm-based for syngas production in the context of Malaysia, where palm biomass is readily available in abundance. The properties and suitability for gasification of the major palm biomass, including empty fruit bunch, oil palm fronds and palm kernel shells are reviewed. Optimization of the gasification process can significantly improve the prospect of commercial syngas production. [ABSTRACT FROM AUTHOR]

Malaysia's framework for energy development was established in the early 1970s. Henceforth, many successive policies were introduced as potential resources for electricity generation and utilization. Currently, as a signatory to the United Nations Framework Convention on Climate Change, Malaysia is sparing a number of effort to comply with the policy to meet the challenges of mitigating over-dependence on fossil fuels, reducing carbon levels, and achieving sustainable national development. This paper reviews the baseline studies on electrical energy policies and the measurement indicators used in Malaysia's electric power system. This research involves a comprehensive survey of electrical energy policies in Malaysia that focus on issues pertaining to energy supply, utilization, its environmental impact and considerations, renewable energy (RE) policies, production and consumption, energy efficiency, and feed-in tariffs. Fourteen energy indicators for sustainable development in Malaysia were investigated through the identification of energy policies in significant areas, such as reliability, safety, adequacy and cost-effectiveness of energy supply; increasing energy efficiency; minimizing environmental impact; and enhancing quality of life in terms of social well-being. The policies and the indicators are classified into different sustainable dimensions and summarized in tables along with the corresponding key references. In this study, future energy planning and options, especially in nuclear and RE programs, as well as the conflict between them, are illustrated through the overall performance relative to targets and benchmarks for past and future projections up to the year 2030. This review seeks to examine the past, present, and future policies and indicators to provide a sufficient overview of Malaysian energy policies for optimizing sustainable development. The goal is for this review to lead to increased efforts to accommodate the increasing demand for the management and utilization of RE, promote energy efficiency, and improve performance in achieving sustainable national development.

Demographic change, dramatic population increase and rapid industrial growth are major trends emerging in Malaysia. Climate change and depletion of fossil fuel along with the rise in petroleum prices have forced the Malaysian Government to rethink strategies to be more in line with other developed countries including the decision to embark on renewable energy (RE) resources as a better source of energy amongst the global energy mix. The Malaysian Government is making frantic efforts to make policies, RE programmes and incentives more effective so as to promote and develop the use of RE. Malaysia is rich with fossil fuel but these are fast depleting. Although RE is necessary, current RE resources are still not enough. Therefore, exploration into other resources must be considered in order to meet future energy demands. The objective of this paper is to identify the potential of available renewable energy resources in Malaysia as well as the country׳s current implementation strategies. This paper also discusses the different RE policies in Malaysia. In order to determine the potential of RE, various sources and published materials in conferences, international journals and information released by relevant government bodies and miscellaneous resources are used. This research has revealed that among all the renewable energy sources that are present in Malaysia, biomass and solar energy are the most prospective ones. Plus, renewable energy (RE) sources are quite advantageous as they are free from greenhouse gas (GHG) emissions and related global warming effects. They can also be applied in off-grid electricity generation for rural communities. [ABSTRACT FROM AUTHOR]

In order to promote the growth of renewable energy sector in Malaysia, feed-in tariff (FiT) mechanism has been introduced by Malaysian government in 2011, in accordance with Renewable Energy Act 2011 and Sustainable Energy Development Authority Act 2011. The tariff was enacted to overcome the shortcomings identified in the small renewable energy power (SREP) Program from 2001 to 2010. This paper highlighted some measures adopted to rectify the shortcomings identified during SREP, and the role of Sustainable Energy Development Authority (SEDA) in achieving the above mentioned task. The paper also includes the latest progress on renewable energy projects, especially those related to solar photovoltaic system. It is predicted that solar energy will become the main source of renewable energy in Malaysia by the year 2050. [ABSTRACT FROM AUTHOR]

Ineffective waste management that involves dumping of waste in landfills may degrade valuable land resources and emit methane gas (CH 4 ), a more potent greenhouse gas than carbon dioxide (CO 2 ). The incineration of waste also emits polluted chemicals such as dioxin and particle. Therefore, from a solid waste management perspective, both landfilling and incineration practices pose challenges to the development of a green and sustainable future. Waste-to-energy (WtE) has become a promising strategy catering to these issues because the utilisation of waste reduces the amount of landfilled waste (overcoming land resource issues) while increasing renewable energy production. The goal of this paper is to evaluate the energy and carbon reduction potential in Malaysia for various WtE strategies for municipal solid waste (MSW). The material properties of the MSW, its energy conversion potential and subsequent greenhouse gases (GHG) emissions are analysed based on the chemical compositions and biogenic carbon fractions of the waste. The GHG emission reduction potential is also calculated by considering fossil fuel displacement and CH 4 avoidance from landfilling. In this paper, five different scenarios are analysed with results indicating a integration of landfill gas (LFG) recovery systems and waste incinerator as the major and minor WtE strategies shows the highest economical benefit with optimal GHG mitigation and energy potential. Sensitivity analysis on the effect of moisture content of MSW towards energy potential and GHG emissions are performed. These evaluations of WtE strategies provides valuable insights for policy decision in MSW management practices with cost effective, energy benefit, environmental protection. [ABSTRACT FROM AUTHOR]

Malaysia, as a developing country and a member of the Association of Southeast Asian Nations (ASEAN), is looking into inexhaustible and repeatable alternative energy sources such as solar, wind, mini-hydro and biomass. The estimated GDP at 2010 is $15,385 per capita and the economic and industrial growth of the country implies that energy demand is growing very fast. In addition, the growing prices of fossil fuels, and greenhouse gas (GHG) emissions, make inevitable renewable energy solutions for the country. Geographically, Malaysia is located in a region of tropical and humid climate which provides easy access to a variety of renewable energy sources. The government of Malaysia has initiated renewable energy policies to encourage industries and individuals to employ renewable-energy-powered systems in power applications. This paper first gives a brief overview of the current status of renewable energy in Malaysia. Then it provides the energy policies, specifically the renewable energy policies in Malaysia, in Section 2 . The renewable energy programs are reviewed in Section 3. The building energy efficiency program with green aspect is provided in Section 4. Lastly, the conclusion and forecasts of this paper are given in Section 5. [ABSTRACT FROM AUTHOR]

Abstract: The Malaysian palm oil industry spans the entire value chain from upstream processes to downstream activities. This paper aims to review the progress of the palm oil industry and the current issues in the plantation sector, such as labor shortage, sustainable production, and greenhouse gas emission from the cultivation process. Palm oil cultivation is known for its labor-intensive process. Foreign laborers are usually employed in Malaysian palm oil plantations for harvesting, fruit collecting, and general maintenance works. Some issues have affected the supply of workers to Malaysian palm oil plantations. Farm mechanization, which has always been recommended as a tool to reduce dependency on foreign workers, is expected to solve the issues. However, certain considerations should be investigated, such as fuel consumption, to reduce its impacts on the environment. The currently available farm machineries that are frequently used contribute to almost 211 million kg of CO2-eq per year, as diesel consumption stands at 290 million L per year. Therefore, this paper also examines the potential renewable energy resources for the palm oil cultivation process. Exploiting renewable energy technologies in plantation operations, such as battery-powered electric vehicles charged using a solar photovoltaic (PV) system, can reduce up to 750 tonnes of CO2-eq per year. Therefore, this initiative will increase the sustainability of the Malaysian palm oil industry in general. [Copyright &y& Elsevier]

The development of renewable energy is of paramount importance towards the energy security and environment integrity of Malaysia. The Malaysia government has been implementing various policies that could facilitate the advancement of renewable energy technology and increase its contribution to the national energy mix to reduce the country dependency on fossil fuels. On the other hand, due to rapid urbanization and population growth, there is also increasing concern over the high production rate of organic waste. Among the renewable energy available, biogas is of great interest due to its ability to treat organic waste and generate power addressing both concerns simultaneously. This paper aims to review some of the important policies on renewable energy followed by the emphasis on solid waste management policies towards effective implementation of biogas generation from municipal solid waste. The biogas network is divided into three phases on a life cycle basis, namely MSW as feedstock, biogas production and biogas utilization. Under each phase, several important stages were identified. Analysis was performed to identify the role of currently implemented policies as well as the lacking support and challenges. It was envisioned that with proper SWM policies, in terms of waste collection, waste segregation and allocation of resources, which can be further complemented with more financial initiatives and technical support under the RE policies, the biogas development in Malaysia can progress more efficiently. Several supportive actions needed were derived from the analysis and presented in three figures, representing each of the phase, which could constitute a solid biogas framework.

Abstract: Building integrated photovoltaic (BIPV) systems are likely to become a dominant type of small-scale embedded generator (SSEG) on public low voltage (LV) distribution network in Malaysia due to the enormous amount of initiatives and efforts taken by the government to promote the use of BIPV. The growth of BIPV systems on LV distribution networks has the potential to alter the direction of power flow across the distribution networks, hence imposing several serious technical issues relating to power quality, distribution system efficiency and possible equipment overloading. Therefore, the utility companies need to study the following technical issues: (i) voltage regulation, (ii) voltage rise, (iii) voltage unbalance, (iv) network power losses, and (v) cable and transformer thermal limits. This paper describes research carried out to investigate and quantify the impacts of BIPV on LV networks with particular reference to developing countries striving to increase the utilisation of renewable energy. This paper presents and discusses the impacts of BIPV systems on two types of LV distribution network: a commercial LV distribution network and a residential LV distribution network in the state of Selangor, Malaysia. The results of these studies are compared with those from European networks to identify how the differences in the electrical network characteristics influence the allowable penetration of small-scale embedded generators.

Abstract: To overcome the negative impacts on the environment and other problems associated with fossil fuels have forced many countries to inquire into and change to environmental friendly alternatives that are renewable to sustain the increasing energy demand. Solar energy is one of the best renewable energy sources with least negative impacts on the environment. Different countries have formulated solar energy policies to reducing dependence on fossil fuel and increasing domestic energy production by solar energy. This paper discusses a review about the different solar energy policies implemented on the different countries of the world. According to the 2010 BP Statistical Energy Survey, the world cumulative installed solar energy capacity was 22928.9MW in 2009, a change of 46.9% compared to 2008. Also this paper discussed the existing successful solar energy policies of few selected countries. Based on literatures, it has been found that FIT, RPS and incentives are the most beneficial energy policies implemented by many countries around the world. These policies provide significant motivation and interest for the development and use of renewable energy technologies. Also the status of solar energy policy for Malaysia is investigated and compared with that of the successful countries in the world. [Copyright &y& Elsevier]

Abstract: Oil palm is one of the major economic crops in many countries. Malaysia alone produces about 47% of the world''s palm oil supply and can be considered as the world''s largest producer and exporter of palm oil. Malaysia also generates huge quantity of oil palm biomass including oil palm trunks, oil palm fronds, empty fruit bunches (EFB), shells and fibers as waste from palm oil fruit harvest and oil extraction processing. At present there is a continuously increasing interest in the utilization of oil palm biomass as a source of clean energy. One of the major interests is hydrogen from oil palm biomass. Hydrogen from biomass is a clean and efficient energy source and is expected to take a significant role in future energy demand due to the raw material availability. This paper presents a review which focuses on different types of thermo-chemical processes for conversion of oil palm biomass to hydrogen rich gas. This paper offers a concise and up-to-date scenario of the present status of oil palm industry in contributing towards sustainable and renewable energy. [Copyright &y& Elsevier]

Abstract: It is estimated that oil reserves will not last very much longer; thus, a switch to alternative energy solutions is crucial. The Malaysian government has already prepared to face the situation decades before. Many policies have been implemented, as well as programmes and initiative. Now, Malaysia is waiting for the ultimate solutions, the Malaysian Fit-in Tariff (FiT), which is scheduled to be implemented second quarter of 2011. This paper presents the main sources of alternative renewable energy in Malaysia and its potential as well as the main reasons Malaysia is turning to alternative energy solutions; to fully utilize its renewable energy (RE) resources, fulfill the energy demand in the future and to reduce carbon emissions. This paper also discusses the steps taken by the government in preparation for FiT and overcoming the barriers in RE development. [ABSTRACT FROM AUTHOR]

Abstract: It has been widely accepted worldwide that global warming is by far the greatest threat and challenge in the new millennium. In order to stop global warming and to promote sustainable development, renewable energy is a perfect solution to achieve both targets. Presently million hectares of land in Malaysia is occupied with oil palm plantation generating huge quantities of biomass. In this context, biomass from oil palm industries appears to be a very promising alternative as a source of raw materials including renewable energy in Malaysia. Thus, this paper aims to present current scenario of biomass in Malaysia covering issues on availability and sustainability of feedstock as well as current and possible utilization of oil palm biomass. This paper will also discuss feasibility of some biomass conversion technologies and some ongoing projects in Malaysia related to utilization of oil palm biomass as a source of renewable energy. Based on the findings presented, it is definitely clear that Malaysia has position herself in the right path to utilize biomass as a source of renewable energy and this can act as an example to other countries in the world that has huge biomass feedstock.

Marine renewable energy (MRE) is yet to be included in the Feed-in Tariff (FiT) system in Malaysia. However, the country is surrounded by the Straits of Malacca and South China Sea, making it suitable to harness energy in the water. Financial supports from the government are essential in developing this technology. This paper aimed to suggest appropriate FiT rates of MRE based on Net Present Value (NPV) approach. Meanwhile, the proposed FiT rates were compared with other implemented FiT rates of MRE in United Kingdom, Germany, France, Republic of Ireland, Italy, Portugal and Korea. The results showed that reasonable FiT rates of MRE in Malaysia should be in the range of €0.06–0.60/kWh depending on the type of MRE technology used. The proposed tariffs were exceedingly higher than the implemented FiT rates of solar photovoltaic ranging from €0.20 to 0.28/kWh due to higher project cost. [ABSTRACT FROM AUTHOR]

Sustainable energy supply is essential for actualizing Malaysia׳s vision to become a high-income country. The current power production and demand trends show that Malaysia has a reserve margin that will only last for the next few years. This calls for further investment, research and development in the country׳s power sector in order to meet the ever increasing energy demand. The government׳s diversification policy and power sector expansion plan emphasizes on the incorporation of renewable energy sources (RESs) and other less CO 2 emitting sources like nuclear into the national energy mix. However, the environmental ramifications of this policy should be part of any future expansion plan of national grid. This paper presents a panoramic overview of the Malaysian energy sector, the energy policy revolution and the power sector expansion strategy towards secure sustainability. We want to bring into focus the benefits and challenges of Malaysia׳s power sector expansion plan with the aim of stimulating further discussion and research on the environmental ramifications of the plan.

Today, global energy consumers are addicted to fossil fuels such as natural gas, oil and coal. Although it has been anticipated that fossil fuels will be depleted soon, these fuels are still dominant as the primary source of energy in the world. Recently, many efforts have been done to substitute renewable alternative fuels to reduce dependency on fossil fuels. Biomass as one of the earliest energy sources appears to be the most promising renewable energy source due to its numerous resources and its environmentally sound characteristics. Since Malaysia is agriculture based tropical country, many crops such as palm, paddy rice and sugarcane are cultivated in this region. Malaysian palm oil industry generate huge amounts of palm solid residue (PSR) biomass such as empty fruit bunches (EFB), palm fiber, shell, trunks and fronds as byproducts which are capable to be taken into account in the energy mix of the country. In this paper, an overview of the PSR generation from Malaysian palm oil industries and its social and economic effects has been given. Indeed, performance of the direct combustion of PSR in terms of PSR composition, properties, heating value, emissions and its effects on the equipment or the components of the boilers have been reviewed. It has been found that the very high moisture content of PSR of palm industry makes their collection and transportation expensive, therefore energy conversion process could be inefficient and utilization of these materials inside the palm oil mills seems more beneficial.

Abstract: Recent surge in crude oil price, finite fossil oil resources, and environmental issues all have aroused grave concerns. The world in 2012 consumed up to 12,476.6 million tons oil equivalent and 87% of this energy came from fossil sources. Malaysia has encountered an increase in energy demand following the country׳s development and economic growth. Currently, biodiesel is one of the main options to replace petroleum-derived diesel. Thanks to its environment friendly properties and almost similar performance with fossil fuels, biodiesel sounds like a promising option. The present paper deals with available renewable energy scenarios and examines alternative energies such as biomass, solar, wind and mini-hydro energy. The purpose of using the new sources of energy is to make sure of availability of reliable and secure supply of energy for the country. The energy demand and supply are also discussed based on source and relation to the country׳s fuel diversification policy. The study evaluates Malaysia׳s status quo in energy and biodiesel market, its strengths from economic, social, and environmental viewpoints and the production of biodiesel in the country. Moreover, the country׳s potentials to become a leading producer of biodiesel are further studied. The concentration in the study is on biodiesel production in Malaysia. The main portion of raw material for producing biodiesel is palm oil as the country is among the largest producers of palm oil at international level. There are optimistic expectations that by developing biodiesel production in the Malaysia, not only will the countries׳ energy needs be met, but the country will emerge as a role model that paves the path toward more production of biodiesel all around the world.

Abstract: The usage of wind energy as a form of renewable energy is becoming increasingly popular year by year. This technology has been applied widely in several regions in the world and already reached maturity in terms of technology, infrastructure and cost competitiveness. The performance of the wind turbine system depends upon factors such as design, aerodynamic performance and material selection. Thus, Structural Health Monitoring (SHM) has become crucial in evaluating the performance of wind turbine in real time. Furthermore, the application of smart material in SHM can be utilized as micro energy harvester as well. Nonetheless, the application of SHM in Malaysia׳s climate for wind turbine is still premature, especially in the approach biocomposites material towards its blade system. Several issues are highlighted in this paper such as Vertical Axis Wind Turbine (VAWT), biocomposites material selection and the issue in the micro energy harvester as well. The issues are discussed and compared with the recent finding in this review. Several recommendations are suggested for future studies in benefiting the Malaysian especially on the application of wind energy to promote better green technology for tomorrow.

Abstract: The biomass wastes from the palm oil industry offer great potential for large-scale power generation in Malaysia. It has been estimated that 85.5% of available biomass in the country comes from oil palm agriculture. The introduction of the FiT (Feed-in Tariff) regime in 2011, which superseded the underperforming SREP (Small Renewable Energy Power) scheme, is expected to catalyse and accelerate the development of the renewable energy industry, including biomass technology. Despite a major overhaul of the market structure under the new scheme, the sustainability of the grid-connected oil palm biomass renewable energy industry downstream components remains questionable. Hence, this paper aims to investigate and analyse the market response to six sustainability-related topics. The research methods include electronic and conventional postal modes to disseminate questionnaires to all of the palm oil producers. The returned questionnaires were then analysed with a statistical tool and inferences were drawn to identify the gaps in the existing policy system. The survey identified several key factors for the government's consideration. [Copyright &y& Elsevier]

Abstract: Photovoltaic (PV) systems are the most promising renewable energy sources in Malaysia because of its location being around the equatorial region where sunlight is available throughout the year. However, the country is warm and surrounded by the South China Sea and Malacca Straits. A large amount of clouds is created and passed over the region. The impacts of the passing clouds on the PV power outputs and voltage magnitude have to be studied thoroughly. Therefore, an experimental low-voltage network integrated with a PV system is set up. The experimental results show that the passing clouds result in the frequent and rapid fluctuations of PV power outputs, hence producing a large amount of flickers to the distribution networks. Some of the flickers are actually greater than the statutory limits. To mitigate this power quality issue, a dynamic load controller is proposed to be the solution because its components are cheap. The load controller is made of a number of 200 W power resistors and solid-state relays. A central controller switches the resistors on and off very rapidly based on the fluctuations of the network voltage. The experimental results show that the dynamic load controller is able to reduce the flickers effectively on the distribution networks. The studies and solution presented in this paper are very valuable to different parties, such as the government, policy makers, utility companies and owners of the PV systems, in order to ensure an effective growth of the PV systems without compromising the quality of electricity supply to the customers.

Abstract: Currently, around 90% of Malaysia's electricity generation depends on fossil fuels. This reliance, in a long run, is not a secure option. However, renewable energy sources can contribute to a sustainable electricity generation system; but diversifying fuel supply chain is a complex process. Therefore, the aim of this paper is two folds. Firstly, various renewable resources potential are reviewed, and secondly an assessment model is developed for prioritizing renewable options. Four major resources, hydropower, solar, wind, biomass (including biogas and municipal solid waste) are considered. Their electricity generation potential, along with any likely shortcoming is also discussed. Moreover, using a multi-perspective approach based on analytic hierarchy process (AHP), an assessment model is developed. AHP model employs four main criteria, technical, economical, social and environmental aspects, and twelve sub-criteria. From the review it was found that renewable resources seem to have a sufficient potential to develop a sustainable electricity system. Furthermore, AHP model prioritize those resources, revealing that solar is the most favorable resource followed by biomass. Hydropower and wind however, are ranked third and fourth, respectively. The model also shows that each resource is inclined towards a particular criterion; solar towards economical, biomass towards social, hydropower towards technical, and wind towards environmental aspect. Besides reporting AHP model for the first time in Malaysian context, the assessment performed in this study, can serve decision makers to formulate long-term energy policy aiming for sustainability.

Abstract: Rural electrification to help rural communities improve their quality of life needs to be designed in a sustainable manner with the intention of keeping village culture and environment from eroding. Micro-hydropower systems (MHS), especially run-of river schemes, are examples of renewable energy projects that, if managed well, can be socially and environmentally sustainable. This paper presents the results of a field survey conducted in Ba'Kelalan, in Sarawak, Malaysia, where several MHS have been implemented by various funding agencies using different planning mechanisms as well as different design and operational procedures. Quantitative and qualitative analyses were used in a case study comparison of two MHS in Ba'Kelalan based on criteria such as system loads, electricity tariff, the level of community involvement in the project, and the arrangements put in place for maintenance. Several barriers to sustainability were found in the operation and maintenance of the MHS due to a lack of knowledge by unskilled operators. The key lessons learnt from the case study are that sustainable development of MHS requires financial and load distribution management at the beginning of the project, as well as capacity building for both operation and maintenance personnel, as well as the community.

Abstract: Municipal solid wastes (MSW) disposal and treatment essentially pose problems in many countries due to their voluminous characteristic. The customary means of MSW management is via landfill disposal but its dependency is gradually being limited by developed countries due to environmental concerns. Even though not apparent as it seems, Malaysia is gradually experiencing scarcity of available land for development. As such, the local government is currently looking into the possibility of employing high-end and large-scale incineration processes to address this issue. MSW as a combustion source for thermochemical conversion application, represents a two-pronged approach in solving its disposal dilemma as well as providing a source of energy fuel. This paper highlights the current issues and future directions as well as energy recovery initiatives associated with incineration of MSW in Malaysia. In Malaysia, energy recovery initiatives are focused on application of waste-to-energy (WTE) as well as refuse-derived fuel (RDF) technologies. Aspects regarding MSW landfill gas capture and energy generation are also discussed since they may directly influence (or potentially compete against) the widespread adoption of RDF technologies. A relatively successful RDF pilot plant in Malaysia is highlighted as a case study. It is deemed that application of large-scale incineration technologies in Malaysia is inevitable as opening of new landfill areas will ultimately cease in the future. [Copyright &y& Elsevier]

Abstract: The need for renewable energy is a global demand due to both the economic factors and the environmental concerns. Malaysian government has been supportive on the research and development in the renewable energies. Renewable Energy Act (2011) and Sustainable Energy Development Authority Act (2011) have been enacted to boost the industry of renewable energy. This paper presents the current status and future prospects of renewable energy in Malaysia with particular focus on the ocean renewable energy.

The comparison of various types of ocean renewable energy has been made to present their recent technologies in electricity generation. Tidal current energy is identified as a preferable option particularly in the Straits of Malacca. [Copyright &y& Elsevier]

Abstract: This paper describes the synthesis of a rubber seed supply network to support the green energy demand in Malaysia. An optimised rubber seed supply network design, which maximises biomass utilisation, secures local biomass supply as well as reduces material loss and emissions resulted from inefficient logistic activities has been carried out. The utilisation of rubber seed oil (RSO) for biofuel production in Malaysia and its contribution to the national biomass renewable energy portion is forecasted. The supply network of the biomass is synthesised through mixed integer linear programming. Both centralised and de-centralised rubber seed processing facilities are studied. The network model shows that the selection of rubber seed processing plant is highly dependant on the volume of feedstock. A simplified real case study is presented to demonstrate the optimisation model. In addition, biodiesel price is largely dependent on the feedstock market. Thus, comparison of crude palm oil (CPO) and RSO production processes have been made in term of (i) energy and utility consumptions, (ii) feedstock price and (iii) environmental impact. Sensitivity analysis of rubber seed oil price for obtaining optimal blending ratio of rubber seed oil and crude palm oil has been performed in order to determine the market uncertainty of the biodiesel price. The potential of substituting rubber seed oil for crude palm oil as an alternative blending feedstock for biodiesel production has been validated. [Copyright &y& Elsevier]

Abstract: Solar energy is one of renewable energy sources which have potential for future energy applications. New technology developments in solar energy utilization are expected to result in the improvement of the photovoltaic performance with lower production cost. This will increase the demand and viability for commercial applications. The current popular technology converts solar energy into electricity and heat separately. The photovoltaic-thermal (PV/T) hybrid system is designed to generate thermal and electrical energy simultaneously. It is well known that using a hybrid system can eliminate the need for external source of electrical energy. This paper presents research and development activity being carried out at Solar Energy Research Institute (SERI), Universiti Kebangsaan Malaysia in order to realise the technology.

Abstract: This paper examines solar photovoltaic (PV) in Malaysia. First, it analyzes the current energy demand in Malaysia and discusses some of the national policies and the installations of solar PV in urban and rural areas in the country. Next, the general Feed-In Tariff (FiT) scheme is explained, indicating its potential as one of the investment options for Malaysians. Finally, the loan financing option for solar PV is presented, providing examples that have been implemented in other countries, as well as explaining the Green Technology Financing Scheme (GTFS) for companies and the proposed soft loan scheme for individual households in Malaysia. It also analyses the impact of the proposed interest rate to household consumers in Malaysia, in terms of total profit, net present value and internal rate of return. It is found that the FiT scheme could potentially help in increasing renewable energy penetration, particularly for solar PV. To provide upfront capital for solar PV installation, it is shown that the GTFS is a good financial source for companies while for individual home owners, a soft loan facility from banking institutions is a feasible source if the interest rate is 5% or less.

This paper addresses the RE progress and achievement over the past 10 years, and discusses the key policies for RE programmes, funding, schemes, and incentives that has been introduced by the government of Malaysia to develop and promote the utilisation of RE. The recent RE mechanisms under the Tenth Malaysia Plan (2011–2015) will also be highlighted. [Copyright &y& Elsevier]

Abstract: Today, energy crisis turn out to be a serious threat towards sustainability for developing countries since their energy demand is growing more rapidly than developed countries. On the other hand, fossil fuels cannot sustain anymore in the near future because of environmental impacts and depletion of the reserves. Malaysia is experiencing drastic growth in population and economy and requires exploring alternative energy sources to support its population and commercial energy demand. Biomass as the fourth largest energy resource in the world is abundant in the country. Malaysia is blessed with tropical and humid climate all year round which is a magnificent opportunity for fully exploiting agriculture and tropical forests potential. Since late 1990, the concept of waste-to-wealth had been promoted and became popular widely. This concept is based on unwanted wastes which are converted into valuable energy while reducing waste generated and increase the economy-efficiency mainly used for cooking, space heating and power generation. Currently, concerted efforts and various biomass energy programs are supporting by the government for development, demonstration and commercialization. This paper intent to present the current state and prospects of biomass utilization and strategies promoted for future developments in Malaysia. [Copyright &y& Elsevier]

Abstract: This paper proposes the use of a PV–wind–diesel generator hybrid system in order to determine the optimal configuration of renewable energy in Malaysia and to compare the production cost of solar and wind power with its annual yield relevant to different regions in Malaysia namely, Johor, Sarawak, Penang and Selangor. The configuration of optimal hybrid system is selected based on the best components and sizing with appropriate operating strategy to provide a cheap, efficient, reliable and cost-effective system. The various renewable energy sources and their applicability in terms of cost and performance are analyzed. Moreover, the annual yield and cost of energy production of solar and wind energy are evaluated. The Simulations were carried out using the HOMER program based on data obtained from the Malaysian Meteorological Centre. Results show that, for Malaysia, a PV–diesel generator hybrid system is the most suitable solution in terms of economic performance and pollution. However, the cost of production of solar and wind energy proved to be cheaper and more environmentally friendly than the energy produced from diesel generators. [ABSTRACT FROM AUTHOR]

Abstract: This paper aims to present the feed-in tariff (FiT) outlook in Malaysia, which is in the process of being enacted through a Renewable Energy (RE) Policy by the Government of Malaysia (GoM).

Abstract: Petro diplomacy has played its role in last few decades and that makes energy security a major concern worldwide. Rapid climate change and environmental protection is another vital issue to be addressed in recent energy policies. So an alternative carbon neutral transport fuel is a must in new sustainable energy mix. Biodiesel has immense potentiality to be a part of a sustainable energy mix. In this energy scenario, Brazil''s success is a role model in utilizing its agro-industry for reducing poverty, greenhouse gas emission and petro-dependency simultaneously. Brazil commercialized bioethanol in mass scale by introducing flexible fuel vehicles in market. This dedicated engine idea moralizes a new concept of dedicated biodiesel engine vehicles for Malaysia and Indonesia. Southeast Asian countries, i.e. Malaysia and Indonesia is the largest producer as well as exporter of palm oil. Growing at highest yield rate among other biodiesel feedstock, palm based biodiesel is a top exported product for this region. This paper will quantify the prospects of a dedicated biodiesel engine vehicle for Malaysia and Indonesia that will initiate palm based biodiesel in fuel supply chain by leapfrogging the barriers of biodiesel utilization by boosting local automobile industry simultaneously. This article will also review on energy scenario of Malaysia and Indonesia and their renewable energy policies and challenges for coming decades. [Copyright &y& Elsevier]

Abstract: This paper presents a Mixed Integer Linear Programming (MILP) model that was developed for the optimal planning of electricity generation schemes for a nation to meet a specified CO2 emission target. The model was developed and implemented in General Algebraic Modeling System (GAMS) for the fleet of electricity generation in Peninsular Malaysia. In order to reduce the CO2 emissions by 50% from current CO2 emission level, the optimizer selected a scheme which includes Integrated Gasification Combined Cycle (IGCC), Natural Gas Combined Cycle (NGCC), nuclear and biomass from landfill gas and palm oil residues. It was predicted that Malaysia has potential to generate up to nine percent of electricity from renewable energy (RE) based on the available sources of RE in Malaysia. [Copyright &y& Elsevier]

Abstract: Many countries have organised energy awards as an instrument to promote energy efficiency (EE), to contribute towards energy sustainability and to provide a mechanism for organisations to continuously search, benchmark and acknowledge initiatives and best practices in EE. To be effective, an award system must be tailored towards the needs, the level of readiness and the acceptance of a nation. This paper presents a framework for implementation of a national EE award in the context of Malaysia. The current energy scenario and energy issues relevant to Malaysia are first highlighted to establish the premise for organising a national energy award. Models and success stories of EE awards in other countries are discussed as possible benchmarks for implementation. The results of a survey conducted on various energy stakeholders in Malaysia confirmed the needs, readiness and acceptance for a national EE award. A framework for the implementation of a Malaysian EE award is proposed based on the survey conducted, and on various models of energy award implementation worldwide. [Copyright &y& Elsevier]

Abstract: Solar energy is the most promising source of clean, renewable energy and it has the greatest potential of any power source to solve the world''s energy problems. However, the problem, is how best to harness this vast amount of solar energy. Nevertheless, even if highly efficient Concentrating Solar Power (CSP) could be made cheaply, there would be considerable change in solar power. This technology is expected to be more efficient and to achieve a manufacturing cost of less than $1/W near future. This paper reviews and elaborates the methodology utilized to design and fabricate the solar dish concentrator and outlines the parameters that can be used to increase the efficiency of solar fraction in parabolic dish concentrator under wet climate environment in Malaysia. The study finally provides ideas to the continually increasing ability of these technologies to concentrate and harness solar energy for electricity production and thus eliminate the growing concern over climate change and how it will hurt the region''s environment, human health and economy.

Abstract: Energy is essential to the way we live. Whether it is in the form of oil, gasoline or electricity, a country''s prosperity and welfare depends on having access to reliable and secure supplies of energy at affordable prices. However, it is also one of the benefits taken for granted by many people, knowing little about the impact of electricity on their lives. Having dependent mainly on oil and gas for half a century, Malaysia has started to realize the importance to adopt renewable energy in the energy mix and continuously reviewed its energy policy to ensure sustainable energy supply and security. This paper examines and discusses the intricacy of the existing and new energy policies, issues and challenges in Malaysia. The overall approach in addressing the energy issues and challenges will continue to focus on adequacy, quality, security and sustainability of both non-renewable and renewable energy supply in the country''s development and the promotion and implementation of its energy efficiency programs. The recently launched National Green Technology Policy is also discussed. [Copyright &y& Elsevier]

Abstract: Several biofuel candidates were proposed to displace fossil fuels in order to eliminate the vulnerability of energy sector. Biodiesel and bioethanol produced from terrestrial plants have attracted the attention of the world as potential substitute. However, due to food vs. fuel competition as well as land consumption of these biofuel, they have brought much controversy and debate on their sustainability. In this respect, cultivation of macroalgae such as seaweed at sea water which does not expend arable land and fertilizers provides a possible solution for this energy issue. Carbohydrates derived from seaweeds contain hexose sugars which are suitable materials for fermentation to produce ethanol. Therefore, it is possible to produce fuel ethanol from seaweeds. The potential and prospective of seaweeds to play the role as a sustainable energy provider are demonstrated in this paper. This study offers a conceivable picture of macroalgae-based third-generation bioethanol biorefinery to stimulate the initiation of the exploration in the related field. [Copyright &y& Elsevier]

Abstract: The world has been relying on fossil fuels as its primary source of energy. This unsustainable energy source is not going to last long and thus, gradual shift towards green renewable energy should be practiced. In Malaysia, even though fossil fuel dominates the energy production, renewable energies such as hydropower and biomass are gaining popularity due to the implementation of energy policies and greater understanding on the importance of green energy. Malaysia has been well endowed with natural resources in areas such as agriculture and forestry. Thus, with the availability of feedstock, biomass energy is practical to be conducted and oil palm topped the ranking as biomass source here because of its high production. However, new sources should be sought after as to avoid the over dependency on a single source. Hence, other agriculture biomass should be considered such as banana plant biomass. This paper will discuss on its potential as a new biomass source in Malaysia. Banana plant is chosen as the subject due to its availability, high growth rates, carbon neutrality and the fact that it bears fruit only once a lifetime. Conversion of the biomass to energy can be done via combustion, supercritical water gasification and digestion to produce thermal energy and biogas. The theoretical potential power generation calculated reached maximum of 950MW meeting more than half of the renewable energy requirement in the Fifth Fuel Policy (Eighth Malaysia Plan 2001–2005). Thus, banana biomass is feasible as a source of renewable energy in Malaysia and also other similar tropical countries in the world. [Copyright &y& Elsevier]

The recent policy of the Malaysian government to promote use of renewable, especially photovoltaic, energy has warranted a feasibility study on supplementing diesel generation in off-grid sites by solar (photovoltaic) electricity to be done in the Malaysian context. This paper addresses the technical viability and economy of using a photovoltaic (PV) system to supplement an existing diesel generator-based supply in a typical secondary school located at an interior, off-grid and rural site of Sarawak state in East Malaysia. The findings of the present study, would therefore, help the Government with a realistic picture of the techno-economic aspects in implementing its vision regarding renewable energy. Presently, a 150 kW diesel generator supplies electricity to the considered school. The study required simulation of the load sharing pattern of the PV–diesel hybrid system taking into account varied weather and insolation conditions of the chosen site. Also, the purchase price as well as the size of the supplementing PV system that would give the lowest life cycle cost have been determined. The PV system was considered in both forms, i.e. with and without battery back-up. It has been found that if the market price for purchasing a PV system would drop to RM 11.02/WP (Ringgit Malaysia; US$1.00=RM 3.80) i.e. US$2.90/WP, a 35 kWP PV system without battery back-up in conjunction with the diesel generator would be able to supply the selected school’s demand at a marginally lower energy cost than the existing diesel-only system. With continuous research and developments, PV price would keep falling in the near future so that a PV–diesel hybrid system with a higher sized PV is expected to be economically more viable. The reported feasibility study can serve as a guideline for making similar studies in the context of another off-grid site. [Copyright &y& Elsevier]

Detailed investigation on the physicochemical characterization of Malaysian crop and agro-industrial biomass residues has been carried out to identify promising feedstock for thermochemical and biochemical energy yield. This study covered a wide range of biomass residues including oil palm frond (OPF), oil palm trunk (OPT), empty fruit bunches (EFB), palm kernel shell (PKS), rice husk (RH), rice straw (RS) and kenaf biomass (K). From the detailed characterization studies based on proximate composition, CHNS/O analysis, calorific value and lignocellulosic content determination, physicochemical properties of biomass residues were correlated with their potential for bioenergy generation. In addition, various analytical techniques such as Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetry (TG) and X-ray fluorescence spectroscopy (XRF) were used to study various microscopic properties of biomass residues such as functional groups, crystallographic structure, thermal degradation and mineralogical composition, respectively. Results showed that in terms of volatile matter, the order followed was; EFB (83.42%) ˃ K (82.70%) ˃ OPT (81.46%) ˃ OPF (76.98%) ˃ RS (76.42%) ˃ PKS (69.66%) ˃ RH (66.65%). Proximate analysis revealed that RH has the highest ash content (18.82%). Notably, minimum undesirable ash material was generated by K (5.73%), EFB (6.56%) and OPT (7.71%) containing high fractions of catalytic species. PKS presented maximum thermochemical potential with higher heating value of 17.32 MJ/kg followed by K (16.66 MJ/kg), OPT (16.34 MJ/kg), RS (16.15 MJ/kg), EFB (16.07 MJ/kg), OPF (14.49 MJ/kg) and RH (14.37 MJ/kg). Due to highest apparent density and maximum content of fixed carbon as well as lignin, PKS can be an interesting energy resource in thermochemical processes. Compositional analysis revealed that OPF, OPT and K were rich in polysaccharide content with much less quantity of lignin. Based on XRD measurements, it was found that EFB and K would be more susceptible to enzymatic digestion due to lower crystallinity index (CrI) compared to other residues. We believe that these investigations could decisively contribute to a better understanding of the influence of different factors related to lignocellulosic biomass feedstock on the efficiency of conversion and biofuel potential.
