Artificial intelligence (AI) plays a significant role in energy systems transformations in smart cities. Climate change and environmental sustainability imposed utilities to shift toward renewable energy resources and technologies applications in recent decades. Renewable energy technology deployment is associated with high initial investment and integration with the existing supply and demand systems. Operation stability has been challenging to integrate renewable energy with the customary old systems. On the other hand, renewable energy ensures sustainable energy and future development with minimum loss and greenhouse gas emissions. Therefore, AI is the primary mover of power systems modernization with high accuracy of management and control. This study tried to evaluate the efficiency and performance of AI in the renewable energy sector, focusing on the European Union as the case study. This study analyzes the first renewable energy processes in the chain and energy from gross to final consumption. Afterward economic consequences of renewable energy using natural resources (solar, wind, etc.) in smart cities are discussed. Finally, the efficiency of AI in renewable energy is examined, followed by future work.

According to the studies conducted by the Energy Consumption Management and Optimization Organization, in the common constructions of the country, energy loss in buildings is often 22% through windows, 22% from floors, and 30% from walls. Applying the principles of energy consumption optimization in coordination with climatic conditions and design uses, as well as the use of active and passive methods, can play an effective role in reducing energy consumption in conventional urban buildings. This research aims to provide solutions that address how to reduce energy consumption while creating quality in the architectural space. These solutions are obtained by recognizing the indicators of sustainable and comparative study with the climate of the desired design context. In the present study, the role of technology and digital tools in the field, which is the first and most important step in locating roles and functions, as well as small-scale designs such as building facades. Then, the architectural recommendations of the climate and international standards were examined, and a total of solutions were presented to reach the zero energy building (ZEB). Finally, the simulation method in Design Builder software analyzed the amount of energy consumption in the residential complex and using the analysis of the researchers' efforts and finding the best answer to the problems of architecture and urban planning; results show a significant reduction in energy consumption to be able to manage available resources in the best way.

Afghanistan is an underdeveloped country with a good rebuilding and developing potential. It is obvious that the amount of energy consumption of each country directly affects its economy and GDP. All economic activities are directly or indirectly linked to the energy sector. That is why the energy sector is considered a backbone of the countries development as well as means of achieving sustainable economic development. Accurate evaluation and studying of the energy market and prediction of the future’s energy market is significant to taking proper decisions, making effective and applicable energy policies and goals regarding energy policies. Consequently, it will have a huge influence on the economic and political future of a country. Fossil fuel has a huge share among the energy consumption sources, as well as playing the main role to run the power sector, transportation sector, and industrial sectors. Exports of fossil fuel are also somehow linked to a proper analysis of the internal demand and production rate as well as capacity in the future. In this research, we present Afghanistan’s fuel demand and its future situation prediction by 2032, based on three scenarios. It has been the first time that such research is performed in Afghanistan and will enable energy and fossil fuel sectors to use, analyze, and explore the findings of this research for the purpose of strategic planning, export and import predictions.

There are promising opportunities to produce clean and sustainable energy from micro, mini, small and large hydropower plants in Afghanistan. The Government of Afghanistan has planned to build several hydropower plants. One of them is Baghdara Dam Hydro-Power project in Kapisa province and is expected to produce 210 MW. In the feasibility study, two dam axis configurations were considered, one creating a small reservoir, the other creating a large reservoir. However, a recommendation comparing advantages and disadvantages was not addressed. In this paper, we compare possible Baghdara Dam axis locations and recommend one for future construction that produces optimal electric power, especially during the winter season, and provides clean potable water to New Kabul City. We have determined that dam location A (with a small reservoir) would need a long tunnel to the power station, which requires advanced technology and accurate geological surveying that is not available in Afghanistan. Axis D (with a large reservoir) will recharge downstream hydropower plants such as Kapar (120 MW), Naghlo (100 MW), Sarobi-1 (22 MW), Sarobi-2 (180 MW), and Daronta (12 MW). The large reservoir will also stop sediment ponding at the Naghlo hydropower reservoir. This case study shares an in-depth technical and practical lessons-learned with researchers, students, and practitioners.

Recently, the consumption of energy in residential buildings has increased. On one hand, urbanization increased energy consumption in residential buildings. On the other hand, construction of nonstandard buildings especially residential buildings, caused excessive energy waste. Implementation of energy efficiency and zero-energy building strategies is one of the best solutions to decrease energy waste and energy intensity in a residential building in Kabul City. This research is conducted to design typical energy-efficient and zero energy building strategies for Kabul City. The majority of people use unrefined fossil fuels for heating. As we know, fossil fuels cause environmental pollution. To burn these fuels, most greenhouse gases GHGs emissions are released in the atmosphere, and these GHGs are very harmful to health and cause different types of illnesses. This study is performed in two stages. First, the construction cost of a customarily built building is calculated. Then, the heat loss and heat gain of this inefficient building are also calculated. The same procedure is repeated for a more efficient and insulated building. After comparing, it is revealed that an insulated building saves 65% of the energy and emits 60% less CO2 compared to the inefficient building. To make this building a zero-energy building, we tried using photovoltaic technology. All-electric loads for this building are calculated, and the components of the photovoltaic system are designed accordingly. Finally, the implementation of energy-efficient and zero-energy building has lots of benefits of cost-saving, being environment-friendly, reduced illness, and individual sustainability for each building.

Kabul river is the main river in Kabul city and eastern Afghanistan which passes through 200 kilometers of the heart of Kabul. For the river to serve its ecological purposes, like water supply and environmental quality control, water flow should be optimized both in terms of quantity and quality. However, the water in its inundation season, spring, is very high in pollution and the river bed is waterless and full of solid wastes throughout the rest of the year. The goal of this research was to present a quantitative assessment of carbon as a water quality parameter in Kabul river in the geography of Afghanistan, to detect probable sources of this pollutant and to suggest feasible pollution management approaches. The study was based on the Material Flow Analysis (MFA) model, developed by the Egyptian-Swiss Research on Innovation in Sustainable Sanitation (ESRISS) Project. The effect of hydropower dams, in the concentration of carbon in the river, as a water quality parameter, was evaluated. A segment of the river between the Naghlo hydropower dam and the Darunta dam was chosen for carbon content analysis. As a result of this analysis, we can provide data for carbon quantity in the specified segment of the river. Moreover, we will be able to apply this methodology for providing water quality analysis for almost any segment of the river and suggest relevant feasible solutions for water pollution problems.

Access to affordable, reliable, sustainable, and clean electricity, goal 7 of SDG, interconnected with 5 other goals and 125 (out of 169) targets of SDGs, is an essential factor to the success of any economic growth strategy. While 89 percent of households reported having access to any kind of electricity forms in the 2013-2014 (Afghanistan Living Conditions Survey), only 29.7 percent received their power from the grid, which covers only a small portion of electrified rural households. To select the most appropriate options for electrification of rural areas, a multicriteria decision-making approach has been used. The Analytic Hierarchy Process (AHP) is a multicriteria decision-making method used combined with GIS to analyze different options. In this paper, a methodology framework incorporating decision analysis techniques has been presented to evaluate and determine a suitable energy system for rural electrification with a perspective on sustainable development goals. Renewable energy, diesel generator, and national grid expansion have been compared to different options from different views and criteria.

Kabul faces challenges with fulfilling energy demand using a problematic conventional electrical grid. Its transportation system is disorganized, and ICT infrastructure is limited as the population growth rate is increasing. Kabul should determine feasible and efficient plans to make its energy system more sustainable and smart. Afghanistan energy utility Da Afghanistan Breshna Sherkat- (DABS) provided electricity demand, consumption, import, amount of thermal electricity and thermal generation data for this research. The data about ICT infrastructure has been extracted from SIGAR reports and transportation data has been obtained from the transportation department in Kabul. Population data come from Afghanistan Central Statistics Organization (CSO). In summary, usage of solar, wind, hydro and biomass energies and electricity by transmission lines are the most feasible and efficient ways to provide the needed electricity. A smart grid can be established through smart metering and energy efficiency as well as some measurement programs. Improved ICT infrastructure can benefit citizens with lower prices, better service, and increased competition. Finally, transportation systems options like electric vehicle (EV), public transportation, and ATMS are recommended.

The lives of 85% of the people of Afghanistan depend on agriculture. Every year, sudden changes in the cost of agricultural products leave most farmers discouraged as they suffer financial losses and are considered the most vulnerable in society. This research is focused on the effects of agricultural cost fluctuation on the life of the farmers, identifying root causes, and describing the role of the agriculture department in managing these changes using questionnaires. Qarabagh, Charaseab, Paghaman, Shakerdare, and Dehsabz are selected for this study. Random sampling selected 30 farmers as respondents. Questionnaires, interviews, and documentary reviews are used to collect data, which were analyzed using interpretive and reflexive qualitative approaches and descriptive statistics. The research shows that price fluctuation of agricultural products discourages farmers from striving for a better life.

Industry has leading contribution in the economic development of the nations, however this sector needs a systematic and sustainable roadmap. From the planning point of view, there should be an IP (Industrial Park) with basic facilities such as water supply, sewerage system, electricity, access roads, and other entities, electricity and heat could be one of the key resources that drives the industrial parks. Kabul has three industrial parks, Pul-e-Charkhi, Arghandi, and Bagrami, and their total electrical demand is 180 MW (Kabul IPs utilize averagely daily in 8-hours of industrial activity 1440 MWh electrical energy). Da Afghanistan Breshna Shirkat (DABS) provides only 100 MW. Therefore, industries complete their electrical shortage by burning fossil fuels and rely on fossil fuels. Kabul IPs daily burn 141.86 toe of fossil fuel for thermal necessity and electric shortage. This fossil fuel creates environmental issues and pollution. According to the Afghanistan Metrology Organization (AMO), IPs are responsible for 30% of greenhouse gases (GHGs) emissions in Kabul city. One of the primary and best ways to solve this problem is the usage of renewable energy sources such as solar, wind, hydro and geothermal energies. Kabul industrial parks annually paid $73.01 million, and the total cost of building the hybrid renewable plant of a CSP and Solar PVs is $545.36 million. The payback time is 7.5 years. In this study, we try to find the electrical and thermal demand of IPs, and after that, the feasibility of a renewable energy park by considering the Kabul IPs metrology data. Moreover, The feasibility of having an eco-industrial park has been studied.

Afghanistan with abundant sources of renewable energies has the plan to generate about 4,500 - 5,000 megawatts of its energy from renewable energies sources until 2032. However, it is still one of the energy importer countries. Human resources are one of the most fundamental and vital parts of a sector. Energy sector also needs enough human resources for its development and improvement. As a sector is developing, its requirement of human resources is increasing. Therefore, the number of its human resources must be increased too. Afghanistan, with a promoting renewable energy sector, has an essential need to have enough human resources for the energy sector. To ensure better future for country’s energy sector, it is necessary to estimate the needed human resources. In this research, we used the potential of renewable energy resources of Afghanistan to estimate the required human resources on construction, installation, operation, and maintenance of renewable energies power plants. Based on this research’s findings, the required number of human resources until 2032 in Afghanistan is estimated over 34,000 people which plays a significant role in job creation as well energy sector empowerment. We suggest that the government of Afghanistan hire the needed human resources through meritocracy to become self-sufficient in the energy industry and to be one of the energy exporter countries.

After the industrial revolution and world technological growth, humanity and society seek to use energy resources more efficiently. The global economy currently relies on electricity for the economic and development of world nations. Electrical energy is used mostly in cities and commercial industries. This study focuses on changing the energy production and consumption patterns in Kabul as it is faced with many challenges and problems in providing needed electrical energy within its power network. For solving these problems and challenges, national policymakers are searching for practical and economical methods to provide electric energy for capital region in a sustainable manner. One suggestion is the storage of electrical energy, which can act when the network is under pressure and to avoid power outages. Electric Energy storage(EES)can be used as a secondary source to those regions which are not connected to the national power network. This research aims to find the most appropriate and practical solutions for the storage of extra and additional electrical energy at Kabul city.
