Energy Mix

Malaysia’s electricity generation mix is mainly based on fossil fuels, particularly natural gas and coal with a smaller share of large hydroelectric and non-hydroelectric renewable energy resources. The present work aims to analyse and assess the ongoing search for alternatives to fossil fuel for electricity generation that the country has been pursuing both environmental preservation and national energy security considerations, thereby suggesting the way forward including potential options to be deliberated. This paper surveys alternative, both practical and theoretical that can be considered technically and economically attractive for Malaysia over the period to 2050. The overall national energy supply and demand situation are first analysed to develop projections that account for the role of renewable energy, particularly that of solar photovoltaic (PV). Next, the paper discusses the progress achieved, and the current status of the national solar PV industry presents the advantages or benefits offered and outlines the remaining challenges. In the same manner, electricity generation from the biogas produced from methane recovery in treating palm oil mill effluent (POME) is assessed. In the final analysis, the paper considers other potential low carbon power generation options to make up the Malaysian energy mix, which include small hydroelectricity, municipal solid waste decomposition in suitably-engineered landfills, nuclear energy using thorium-based technology, and renewable marine energy particularly ocean thermal energy conversion (OTEC), in tandem with savings expected from energy efficiency and conservation (EE&C) initiatives.

Abstract As the exhaust rate of the conventional sources has geared up already, this is compelling the power industries to install the power plants based on the non-conventional sources so that future demand of the energy supply can be fulfilled. Among the various sources of renewable energy like wind, hydro, tidal etc., solar energy is the most easily accessible and available renewable energy source. Ensuring the feasibility of any energy source not only technical but also the economical perspective is the most important criteria. This paper has incorporated both the perspective and has done the techno-economic analysis to determine the optimum combination of the PV array size and battery size to minimize the overall electricity generation per unit. In this paper, a standalone solar PV system has been analyzed for the location of Jamshedpur, where an effort has been done to choose the optimum combination of the solar array and battery size within the desired range of LLP so that the electricity generation cost per unit can be minimized. The overall duration of the analysis has been done for a year and the outcome of the research has been verified with the help of MATLAB software.

Engineering Approach

This study proposes a method to estimate the appropriability of renewable energy resources at the global scale, when Earth system boundaries/needs and the human demand for chemical energy are respected. The method is based on an engineering approach, i.e., uncertainties of parameters and models are considered and potentials calculated with 99 % confidence. We used literature data to test our method and provide initial results for global appropriable technical potentials (ATP) that sum up to 71 TW , which is significantly larger than the current global energy demand. Consequently, there is sufficient renewable energy potentially available to increase energy access for a growing world population as well as for a development towards increasingly closed material cycles within the technosphere. Solar energy collected on the built environment ( 29 % ) and in desert areas ( 69 % ) represent the dominant part of this potential, followed in great distance by hydro ( 0.6 % ), terrestrial heat ( 0.4 % ), wind ( 0.35 % ), and biomass ( 0.2 % ). Furthermore, we propose indicators to evaluate an energy mix on different levels, from an energy mix in single products to the mix used by the global economy, against the estimated RE potentials, which allow an evaluation and consideration in the design of sustainable–circular products and systems.

The lauded Renewable Energy Independent Power Producer Procurement Program (REIPPPP) has achieved much in stimulating private sector investment in the renewable energy market in South Africa. Yet, 95% of electricity generated is still from a single source, the state-owned utility Eskom. This paper set out to explore the policy sphere governing electricity generation and identifying possible avenues that can contribute to a more vibrant solar energy market in the most solar abundant province of South Africa, the Northern Cape Province. Licensed mines were identified as low hanging fruit due to a large policy overlap and leeway within existing mining policy. A solar audit of these areas was performed, based on accepted multi-criteria decision analysis techniques, and found that a potential 369 TWh to 679 TWh per annum can be generated, exceeding South Africa’s current electricity usage.

Low Carbon Energy

The world is entering a new energy era marked by concerns over energy security, climate change, and access by the poor to modern energy services. Yet the current energy path is not compatible with sustainable development objectives. Global demand for energy will continue to grow; so will CO2 emissions. Achieving a low-carbon energy world will require an unprecedented technological transformation in the way energy is produced and used. That transformation has begun, as renewables capacity continues to grow, prices continue to fall, and shares of global energy from renewables continue to increase. Government policies are the main driver behind renewable energy's meteoric growth. Still, the world is tapping only a small amount of the vast supply of renewable energy resources. There is broad consensus that the role of these resources should be expanded significantly in order to meaningfully address energy security, energy access, and climate change.

Malaysia has realised the importance of renewable energy (RE) in the energy mix and continuously reviewing its energy policy to ensure sustainable energy supply. The use of RE is among the options although the RE capacity is still underutilized. Malaysia achieves 5.5% share of RE in the energy mix by 2015, and the RE sector is expected to double by 2020 with strong growth in the solar photovoltaic (PV), biomass and biogas markets. Beyond 2020, it is predicted that solar energy will surpass all other forms of RE for Malaysia and other countries, and the solar power will be the long term source of energy supply. After an investigation on the RE policy, the domestic solar PV manufacturing scenario is elaborated in this paper. This includes the solar PV manufacturing, issues and trade disputes, and the way forward. Among the key findings from this paper include: the foreign direct investment (FDI) related to RE sector especially from the US and lately China, have increased rapidly, and more ‘green' jobs in the solar PV manufacturing and installation sectors have been created. With the existence of trade disputes between the United States and the European Union with China, Malaysia has the potential to reap benefits with the inflow of direct investments from China. Nevertheless, the future incidence of RE trade disputes is still uncertain.

Over the last decades, the energy market around the world has reshaped due to accommodating the high penetration of renewable energy resources. Although renewable energy sources have brought various benefits, including low operation cost of wind and solar PV power plants, and reducing the environmental risks associated with the conventional power resources, they have imposed a wide range of difficulties in power system planning and operation. Naturally, classical optimal power flow (OPF) is a nonlinear problem. Integrating renewable energy resources with conventional thermal power generators escalates the difficulty of the OPF problem due to the uncertain and intermittent nature of these resources. To address the complexity associated with the process of the integration of renewable energy resources into the classical electric power systems, two probability distribution functions (Weibull and lognormal) are used to forecast the voltaic power output of wind and solar photovoltaic, respectively. Optimal power flow, including renewable energy, is formulated as a single-objective and multi-objective problem in which many objective functions are considered, such as minimizing the fuel cost, emission, real power loss, and voltage deviation. Real power generation, bus voltage, load tap changers ratios, and shunt compensators values are optimized under various power systems’ constraints. This paper aims to solve the OPF problem and examines the effect of renewable energy resources on the above-mentioned objective functions. A combined model of wind integrated IEEE 30-bus system, solar PV integrated IEEE 30-bus system, and hybrid wind and solar PV integrated IEEE 30-bus system are performed using the equilibrium optimizer technique (EO) and other five heuristic search methods. A comparison of simulation and statistical results of EO with other optimization techniques showed that EO is more effective and superior.
