  • Is Malaysia Ready for Sustainable Energy? Exploring the Attitudes Toward Solar Energy and Energy Behaviors in Malaysia
    Article Is Malaysia Ready for Sustainable Energy? Exploring the Attitudes toward Solar Energy and Energy Behaviors in Malaysia Ai Ni Teoh 1,* , Yun Ii Go 2 and Tze Chuen Yap 2 1 School of Social and Health Sciences, James Cook University, Singapore 387380, Singapore 2 School of Engineering and Physical Sciences, Heriot-Watt University Malaysia, Putrajaya 62200, Malaysia; [email protected] (Y.I.G.); [email protected] (T.C.Y.) * Correspondence: [email protected] Received: 30 June 2020; Accepted: 27 July 2020; Published: 1 August 2020 Abstract: To meet the larger demand for electricity supply, Malaysia needs to achieve two main psychosocial conditions, among others—having the awareness of renewable energy and demonstrating energy-conserving behavior. To examine whether Malaysia has met these two conditions, we recruited 225 participants (n = 109 women, n = 113 men, n = 3 did not indicate) to complete a series of questionnaires. The results showed that the public was aware of the option of solar energy but was not ready to install solar photovoltaic panels after being told the cost incurred. Furthermore, the public did not show satisfying energy-conserving behaviors. To boost the installation of solar power, increasing the public’s energy knowledge and implementing policies to reduce the installation cost might be helpful. These findings highlighted Malaysia’s low readiness for solar power and shed some light on what needs to be done to be better prepared for solar power. Keywords: attitude toward renewable energy; energy-conserving behaviors; renewable energy; solar photovoltaic panel; solar power 1. Introduction 1.1.

  • Rural Electrification in East Malaysia - Achieving Optimal Power Generation System and Sustainability of Rural Electrification Projects
    Rural Electrification in East Malaysia - Achieving optimal power generation system and sustainability of rural electrification projects Tian Shen Liang Master of Science Thesis KTH School of Industrial Engineering and Management Energy Technology EGI-2016-069 SE-100 44 STOCKHOLM Master of Science Thesis EGI-2016-069 Rural Electrification in East Malaysia - Achieving optimal power generation system and sustainability of rural electrification projects Tian Shen Liang Approved Examiner Supervisor 26/1/2016 Viktoria Martin Viktoria Martin Commissioner Contact person Tian Shen Liang 1 Abstrakt Syftet med detta projekt är att föreslå förbättringar till en icke-statlig organisation i Malaysia, Lightup Borneo, för utformning av ett optimalt elproduktionssystem som kontinuerligt kan leverera el. Dessutom diskuteras hur hållbarhet kan uppnås i elektrifieringsprojekt på landsbyggden. Projektet har sträckt sig över sex månader, och inkluderar resultat från faktainsamling, fältarbete, samt en datorsstödd fallstudieanalys med hjälp av mjukvaran Homer. Statliga program för elektrifiering har undersökts, och verkar som referenser för genomförande av projektets mål. Kampung Mantapok valdes som föremål för fallstudien. Det system som för närvarande är installerat i denna by består endast av en 10 kW mikrovattenkraftverk med en enkel kontrollmodul. Byns totala elbehov är 53.72 kWh/d, med dagliga toppbelastningar kl 11 samt 17. Ett antal systemkonfigurationer, baserade på faktorförsök har utvärderas med HOMER. En systemkonfiguration bestående av en 10 kW mikrogenerator för vattenkraft, en 3 kW inverter samt två 280 Ah batterier valdes. I denna utformning erhölls det lägsta COE och NPC – RM 0.181 (US$ 0.045) respektive RM 46,230 (US$ 11,558). Denna konfiguration tillgodoser 100% av elbehovet på årsbasis.

  • Energy Security, Energy Efficiency, and Energy Dialogue
    January, 2013 Energy Security, Energy Efficiency, and Energy Dialogue Introduction Energy Security Energy security is defined by the International Energy Agency (IEA) as the secure and affordable supply of energy. Energy security is a term for the association between national security and the availability of natural resources for energy consumption. In recent years, the challenge of climate change has resulted in the concept being refined to be “the provision of reasonably priced, reliable and environmentally- friendly energy”. To provide energy security is to ensure the reliable supply of energy services to consumers at a price that they can afford and in a way that does not damage the environment. Energy security means different things in different places. This view of energy security focuses on the interests of energy importing states as the emphasis is upon security of supply and affordability. Energy-exporting states tend to emphasise security of demand. They want to ensure that they receive a fair price for their energy exports and that there will be sufficient future demand to justify investment in expensive energy projects. Thus, there is a clear difference between the interests of energy importing economies and the demands of energy exporting economies. Energy security which has been a non-traditional security issue now plays an important role in national security of any given country. It has become one of the most important strategic challenges facing the world today. Access to cheap energy has become essential to the functioning of modern economies. However, the uneven distribution of energy supplies among countries has led to significant vulnerabilities.

  • Chapter 4. Distributed Energy System in Malaysia
    Chapter 4 Distributed Energy System in Malaysia Introduction Off-grid power generation is meant to supply remote or rural areas, where grid connection is almost impossible in terms of cost and geography, such as island, aboriginal villages, and areas where nature preservation is a concern. Harnessing abundant renewable energy sources using versatile hybrid power systems can offer the best, least-cost alternative solution for extending modern energy services to remote and isolated communities. The Tenth Malaysia Plan (2011–2015) prioritised rural development to enhance inclusivity as the nation progressed towards becoming an advanced inclusive nation. Rural development focused on uplifting the well-being of the rural community and stimulating economic activities based on land and natural resources. It also emphasised providing rural basic infrastructure, which resulted in the increase of rural water and electricity supply as well as nationwide road coverage. The coverage of rural roads expanded by 11.7% from 45,905 kilometres (km) in 2009 to 51,262 km in 2014. In Sarawak, 250 km of ex-logging roads were upgraded to provide access to 31,512 people in underserved rural areas. In terms of utilities, coverage of rural electricity reached 97.6% and water supply 93.8%; 188,270 water tanks were also provided to supply clean water to 251,200 rural households in the remote areas of Sabah and Sarawak. Under the Eleventh Malaysia Plan (2016–2020), the Rural Electricity Supply Programme will continue to focus on off-grid generation for remote and isolated areas. The government will also establish partnerships with non-governmental organisations to develop renewable energy sources for the rural community.
