Palestine is an occupied developing country which has a complicated energy sector. Renewable Energy (RE) resources are considered the optimal practical solution to mitigate or resolve the energy crisis in Palestine. Most of Palestine receives solar radiation about 3000 hours annually, and the average solar radiation values range from 5.4 kWh/m2.day to 6.0 kWh/m2.day. These results of solar radiation, in addition to the absence of political restrictions on the use of solar energy technology, make solar energy the most viable and feasible choice among other renewable sources. This work objective is to introduce a comprehensive review of the solar energy prospects in Palestine, its geographical data, applications, legislative, and economic potential in contrast to established projects and modules. This review is based on introducing analyzed information about solar energy characteristics in Palestine, Applied solar systems and technology, the policies and legislation, and a recap of strengths, drawbacks, and recommendations. Results showed that best locations for PV solar energy exploitation are Gaza and south West Bank, and worst is Jericho, which leads to resolve many developmental issues in both rural and urban areas.","PeriodicalId":208155,"journal":{"name":"American Journal of Modern Energy","volume":"522 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123205041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aims to determine the direction and rate of change in land use as a means of assessing the impact of climate change in Central River Region (CRR) of The Gambia. Decadal satellite images were used to measure changes in land use and land cover from 1984 to 2017 using supervised classification. Eight land use and land cover types were identified and mapped in this study namely: Crop lands, Gambia River, Halophytic vegetation, Irrigated crops, Mangrove, Settlement, Shrub/Wood savanna and Wooded savanna. The areas of crop lands, halophytic vegetation and settlement expanded between 1984 and 2017. River Gambia, irrigated crops, mangrove, shrub/wood savanna and wooded savanna areas decreased during the same period. Transition to less savanna was higher than transition to more settlement. In addition, physicochemical parameters were analyzed during the rainy and dry seasons for correlation with climate data. Socioeconomic surveys based on structured questionnaires were also conducted with 70 households in 6 villages in CRR. Land clearing for agriculture, tree cutting for firewood and charcoal, settlement and livestock grazing were mainly cited by the respondents as the main culprit inducing land cover change in CRR. This study shows that deforestation and forest degradation are still in progress despite the implementation of a management plan for a full rotation. We therefore proposed best management practices in order to control the agricultural clearing of land in the region such as agricultural intensification and soil fertility improvement.","PeriodicalId":208155,"journal":{"name":"American Journal of Modern Energy","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134495942","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This value determines the minimum value at which energy could be sold during the lifetime of the installation, and this value is considered as the net present value of unit cost electricity. It is estimated dividing the net present value of the total expenditure by the total production. The LACE is the Levelized Avoided Cost of Electricity or Energy which is a measure of income for the unit value of electricity. Of course, the value of LCOE should be less than the LACE for considering the project, these metrics are necessary but not sufficient to start the project. For overcoming these difficulties, in this paper MLCOE (Modified Levelized Cost of Electricity or Energy) and MLACE (Modified Avoided Cost of Electricity or Energy) are introduced to the calculations for considering dominant factors of construction of a plant and these are the actual estimations of CAPEX (Capital Expenses) and OPEX (Operation Expenses) through the payback period.

It is essential to introduce the importance of using natural and climatic resources responsibly, these being crucial for people, society and environment. Investigating a series of project resources allows mitigating and reducing environmental impact generated by a building as a contribution to climate change. Digital tools and calculation methods will allow verification of the correct location of construction on site, study orientations, solar radiation, prevailing winds and efficient envelope design preferably materialized with materials from the region. The knowledge of site and climate and correct control and management of energy and materials, are aspects that make the project sustainable, therefore, they are taken into account in the teaching of the subject as a starting point in the student's task as a future professional of architecture. The proposed practical exercise must comply certain items that are partially and methodologically resolved as the theory is taught. We work on three types of single-family homes on ground floor implanted in a bioclimatic area of your choice. Students must analyze them according to climatic principles and strategies to determine which typology is best adapted according to the passive design criteria and recommendations for said area. This implies verifying dimensional and energy indicators and building thermal quality of buildings. Through modality of integration seminar that consists of a graphic and quantitative synthesis, debate and exchange of ideas and final reflections are carried out. The objectives indicated from the teaching-learning were successfully achieved, with the theoretical topics applied correctly.

This paper identifies the determining control factors that influence the fuel energy choice for lighting purposes in Rwanda by applying the Multinomial logit regression to the national representative survey at household level data. The study revealed that the households with higher income are adopting to use the cleaner and modern fuel energy source, confirming the hypothesis for energy ladder. Not only household income exerting impact on the fuel energy choice for lighting, the other fuel choices significant determining variables in Rwanda are: number of the rooms occupied by household, type of dwelling for household, age of the household head, whether the household head has formal education level, the household size, type of the habitant for the household and the location of the household. This paper suggests deployment and utilization of solar potentiality for supplying the cleaner and modern fuel energy for lighting purposes in the remote area of Rwanda.","PeriodicalId":208155,"journal":{"name":"American Journal of Modern Energy","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121115736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water scarcity affects the environmental, economic and developmental activities of an area. The rainfall in the sub-basins is often very local, erratic, unreliable and unevenly distributed over the whole area of Dawa sub-basin. The pastoral and agro-pastoral communities are usually vulnerable to drought. The present study was an attempt to describe the state of Rain Water Harvesting (RWH) techniques and the contribution of Remote Sensing and GIS technologies for this RWH in the Dawa Sub basin. The study was conducted using physiographic factors of Dawa sub basin. Landsat image with spatial resolution 30m were used to identify LU/LC types. The thematic layers used were land use/land cover, slope, soil, drainage and runoff from derived from Landsat and collateral data. The image processing software Erdas IMAGINE and GIS software were used to process the image and to establish a geo information system by comprising digital data set of satellite image, topography, soil, metrology, drainage density and metrology. This data was used to study RWH was used to study the watershed network in the Dawa sub basin and to identify areas generally suitable for water harvesting in order to determine water harvesting techniques for those sites. Analytical Hierarchy Process (AHP) was used to calculate weighting and the analysis result indicates that the sub-basin supports promising opportunity for the establishment and development of RWH structures. From the total area of 17,402.7 km 2 , The GIS evaluation predicts that 3,092.342 km 2 (22.853%) is extremely suitable, 4,524.221 km 2 (33.435%) is very suitable, 2,968.685 km 2 (21.939%) is suitable, 1,988.986 km 2 (14.7%) is less Suitable and 957.18 km 2 (7.07%) is not suitable for RWH.
