Abstract— The paper aims to study the relationship between economic growth and CO 2 emissions in MENAP countries over the period 1994 to 2011. Breusch-Pagan LM cross-sectional dependency test, CADF panel unit-root test and Westerlund panel cointegration test have been used for the estimation. Quadratic and cubic polynomial random coefficient panel regression models (RCM) were estimated using carbon emission, economic growth and energy consumption variables. Quadratic and cubic RCM models were estimated for two sub-sample individual countries, oil-exported MENAP countries and others MENAP countries. As a result of panel unit-root test, all variables are stationary in first difference. Panel cointegration test represented that there is a long term relation among carbon emission, economic growth and energy consumption variables. In oil-exported MENAP countries, quadratic random coefficient panel regression model results proved that there is U-shaped and monotonically increasing shape, cubic random coefficient panel regression model showed that there is monotonically decreasing and N-shaped. In others MENAP countries, quadratic random coefficient panel regression model results proved that there is an inverted U-shaped, cubic random coefficient panel regression model showed that there is N-shaped. Consequently, Environmental Kuznets Curve (EKC), inverted U-shape, is valid only other MENAP countries, excluding Morocco, at the quadratic model. And, EKC reformed N-shaped in cubic model in the same

Unpredictable failures of wind turbines and the associated costs; have contributed to the development of condition monitoring systems. The availability of ultra-low power devices has contributed in creating autonomous systems that operates on energy harvested from the surrounding environment. This research aims to develop a design of a self-sufficient condition monitoring system, that is able to run on renewable energy. Energy is harvested from an electromagnetic energy harvester that harnesses the rotational motion of the wind turbine blades and converts it to useful power. After conditioning and storing the harvested energy, the maximum available power is 435 mW. The energy harvested is used to charge a lithium ion battery for backup as well as power the condition monitoring system. The system is validated by both simulation models and experimental measurements on a wind turbine prototype model.

Abstract—Energy Harvesting Technologies for wireless electronics networks have undergone a tremendous development in the recent past. Several micro level energy generating units have been developed to convert variety of renewable energy sources to useable electrical energy. In order to integrate and exploit maximum benefits from renewable sources, an intelligent power electronics interface is mandatory. This paper presents a multiport power electronics circuitry to extract maximum energy from renewable energy sources and route it to power up wireless electronics networks. This new topology has ability to cope with different voltage level requirements and is capable of integrating several energy sources to satisfy the variable load demands. The sources can be utilized independently or concurrently. Surplus energy can also be stored and made available in case of absence of renewable energy sources. Analytical and simulation results in Continuous Conduction mode are presented and are validated by experimental results on a prototype model.

In this paper, in an effort towards reducing indoor air pollution (IAP) exposure for cookstove users, an improved biomass cookstove has been proposed. A computational fluid dynamics (CFD) combustion study has been carried out for the proposed cookstove to analyze the combustion and heat transfer behavior using ANSYS Fluent Simulation. The wood combustion phenomenon inside the stove is modelled as gaseous combustion of volatiles generated by pyrolysis. Temperature gradients, velocity profiles and combustion product concentrations are presented. Based on comparison of CFD predicted results with a popular commercial improved cook stove (ICS), it was concluded that the proposed cook stove yields reduced combustion product concentrations as well as faster cooking resulting in better energy efficiency and a health friendly cook stove.

One of the cleanest energy sources is geothermal. To generate electricity or to directly use as heat this sustainable resource proper investigation of reservoir characteristics is required. The purpose of this research is to determine the best prospect location of geothermal reservoirs for further investigation in Afghanistan. To achieve this goal, the geological, geophysical, and geochemical evidence maps (such as volcanic dome and rock, fault, high temperature, intrusive rock, geopressured, hot spring, and hydrothermal mineral areas) were created in GIS (Geographical Information System) ArcMap 10.1. The GIS geoprocessing tools (such as buffer, union, and intersection) were used to define the best prospect areas of geothermal energy resources. The result of this study is the first digital map of prospect areas for geothermal resources in Afghanistan. Besides known hot springs, it has determined the wide potential areas around the load centers and big cities of the country.
地热是最清洁的能源之一。为了发电或直接作为热能利用这种可持续资源，需要对储层特征进行适当的研究。本研究的目的是确定阿富汗地热储层的最佳远景位置，以供进一步调查。为此，在GIS (geographic Information System) ArcMap 10.1中创建了地质、地球物理和地球化学证据图(如火山穹窿、断层、高温、侵入岩、地压、温泉和热液矿区)。利用GIS地质处理工具(如缓冲区、联合和交集)确定了地热能资源的最佳远景区。这项研究的结果是阿富汗地热资源前景区的第一张数字地图。除了已知的温泉外，它还确定了全国各大枢纽和大城市周围的广阔潜力区域。
