Research ArticleOpen accessIn the abstractThe Potentialof Renewable Energy: Using The Environmental Kuznets Curve ModelJamalludin Sulaiman, Azlinda Azman, Behnaz SabooriThis study examines the potential of Renewable Energy Sources (RES) in reducing the impact of carbon emission in Malaysia and the Greenhouse Gas (GHG) emissions, which leads to global warming. Using the Environmental Kuznets Curve (EKC) hypothesis, this study analyses the impact of electricity generated using RES on the environment and trade openness for the period 1980-2009. Using the Autoregressive … …American Journal of Environmental Sciences, Vol. 9, Issue 2 · 13 Mar 2013 · 14,783 accessesView PDFCite
Research ArticleOpen accessIn the abstractGaseous Emissions and Combustion Efficiency Analysis of Hydrogen-Diesel Dual Fuel Engine under Fuel-Lean ConditionPrateep Chaisermtawan, Sompop Jarungthammachote, Sathaporn Chuepeng, Thanya KiatiwatExhaust gas emissions from diesel engine combustion using alternative fuel may change in their quantities that can affect exhaust gas after-treatment devices and environmental ambient. This study presents theoretical analysis of combustion generated emissions and efficiency of hydrogen-diesel duel fuel in fuel-lean condition. A chemical equilibrium method by minimizing Gibbs free energy is employed to estimate exhaust gas products from … …American Journal of Applied Sciences, Vol. 9, Issue 11 · 1 Sep 2012 · 7,514 accessesView PDFCite
Research ArticleOpen accessIn the abstractIntegrated Electricity Planning Comprise Renewable Energy and Feed-In TariffHo Wai Shin, Haslenda HashimProblem statement: Mitigation of global warming and energy crisis has called upon the need of an efficient tool for electricity planning. This study thus presents an electricity planning tool that incorporates RE with Feed in-Tariff (FiT) for various sources of Renewable Energy (RE) to minimize grid-connected electricity generation cost as well as to satisfy nominal electricity demand and CO2 emission … …American Journal of Engineering and Applied Sciences, Vol. 5, Issue 1 · 28 Feb 2012 · 8,701 accessesView PDFCite
Research ArticleOpen accessIn the abstractAnalysis of Eco friendly Refrigerants Usage in Air-ConditionerC. Chinnaraj, R. Vijayan, P. GovindarajanProblem statement: There are two types of global warming contributions through refrigeration and air conditioning systems. The first one is the Direct Global Warming Potential (DGWP) due to the emission of refrigerants and their interaction with heat radiation. The second one is the Indirect Global Warming Potential (IDGWP) due to the emission of Carbon Dioxide (CO2) by consuming the energy … …American Journal of Environmental Sciences, Vol. 7, Issue 6 · 27 Dec 2011 · 8,467 accessesView PDFCite
Research ArticleOpen accessIn the abstractMicrobial Activities as Affected by Peat Dryness and AmeliorantEdi Husen, Fahmuddin AgusProblem statement: Acceleration of microbial activities and thus of CO2 emission in drained peat soils used for agriculture, is of the main environmental concern. The objectives of this study were to (i) examine microbial activities in peat samples treated with different levels of water contents and ameliorants and (ii) evaluate the relative contribution of microbial groups to peat respiration. Approach: … …American Journal of Environmental Sciences, Vol. 7, Issue 4 · 29 Sep 2011 · 7,548 accessesView PDFCite
Research ArticleOpen accessIn the abstractAssessing Forest Plantation Productivity of Exotic and Indigenous Species on Degraded Secondary ForestsYetti Heryati, Arifin Abdu, Mohd Noor Mahat et al.Problem Statement: There is general agreement that human activities such as deforestation and land use change to other land use types have contributed to degraded secondary forests or forestland and increases the emission of greenhouse gases which ultimately led to global climate change. An establishment of forest plantation in particular is regarded as an important approach for sequestering carbon. However, … …American Journal of Agricultural and Biological Sciences, Vol. 6, Issue 2 · 6 Jun 2011 · 10,520 accessesView PDFCite
