<span>We have, an overview is presented of the potential future demands and possible supply of solar energy to Iraq. Solar energy, which is clean, unlimited, and environmentally friendly, is presented as a renewable energy resource. Many problems such as CO<sub>2</sub> emissions, industry, human activities, and electricity distribution grids have attracted much attention because of the current state of crude oil production and its prices. Moreover, estimations of solar radiation levels and of the efficiencies of photovoltaics (PVs), concentrated solar power (CSP), and solar chimney towers, have all been investigated. Those systems that combine various sources of energy are called hybrids and they have received much attention in recent decades. The basic features of solar radiation in Iraq are outlined, and the selection of those sites with potential for development of solar plants is based on the local largest solar radiation. Moreover, longitudinal and latitudinal orientation, wind, solar intensity, dust, temperature, rain, humidity, and pollution factors are all considered in the calculation of PV/CSP efficiencies. We know there is an abundance of fossil fuels in Iraq, energy shortages began in 1991 because of the perturbation caused by the full ruin of the country. The obvious renewable energy resource available in Iraq is the solar energy, and its exploitation would provide a means to reduce CO<sub>2</sub> emissions from the burning of fossil fuels and to achieve self-sufficiency of electric energy and export the rest to neighboring countries. Solar energy is becoming increasingly important because of the climatic change in the form of global warming.</span>

Solar Energy Utilization

AbstractPhotovoltaic systems are very efficient concerning proper utilization of solar radiation. However, the nanotechnology solution can replace the photovoltaic by the use of new production technology to lower the price of solar cells to one tenth. Sun provides nearly unlimited energy resource, but existing solar energy harvesting technologies are quite expensive and cannot compete with fossil fuels. The central part of Poland, which represents about 50 percent of the area, gives solar radiation at the level of 1000 kWh·m−2/year. Other new developments, which can help improve existing efficiency of solar systems are: diatoms utilization, artificial photosynthesis, nanoleaves and rotation solar towers.

The presented article examines the issues of energy security of the Nakhchivan Autonomous Republic, which is an integral part of the Republic of Azerbaijan, and the use of renewable energy in its provision. For this purpose, the solar energy resources of the Autonomous Republic were studied. The study used theoretical, computational, observational and comparative analysis methods to estimate solar energy as a renewable energy resource. The main source for assessing the potential of solar energy of the Autonomous Republic — experimental and observation materials of the USSR Hydrometeorological Committee on the Republic of Azerbaijan and NAR for 1960–1980, the results of researches of the Institute of Geography of the Azerbaijan National Academy of Sciences for 1936–1950, Nakhchivan AR experimental-observation materials of the Hydrometeorological Center for 1995–2015, static indicators of Nakhchivan Solar Power Plant for 2016–2017, as well as the results of theoretical and computational research were used. As a result of the study, it was determined that the annual value of total radiation (Q) in the horizontal area was 7541 and 6204 MC/m2, respectively, in the clear and medium cloudy sky. At the same time, the average annual transparency coefficient was 0.8229, 0.811 in winter and 0.897 in summer. The annual value of total radiation (Q) of the horizontal field in the territory of the NAR is higher than in other regions of the country, and the coefficient of transparency of the atmosphere is higher than in other regions, too. At the same time, the duration of solar radiation in the NAR is high and is 2792 hours. Formulas have been proposed to calculate the value of solar radiation falling on a horizontal surface on the basis of many years of experimental and observational materials. Using these calculation formulas, it is possible to calculate the total solar radiation on the horizontal surface for any area of the NAR.

AbstractThis paper presents technical and economic assessment of a hybrid energy system for electricity generation in rural communities in the six geopolitical zones of Nigeria. The study was based on a 500 rural household model having an electric load of 493 kWh per day. To simulate long-term continuous implementation of the hybrid system, 21 years (1992 – 2012) hourly mean global solar radiation and wind speed data for the selected sites were used. The mean annual wind speed and solar radiation for the locations ranged from 2.31 m/s for Warri to 3.52 m/ s for Maiduguri and 4.53 kWh/m2 for Warri to 5.92 kWh/m2 for Maiduguri, respectively. These weather data were used for simulation with the Micro-power Optimization Model software HOMER. From the optimum results of the hybrid system,Warri has the highest NPC and COE of $2,441,222 and $0.721/kWh, respectively while Maiduguri has the least NPC and COE of $2,225,387 and $0.658/kWh, respectively for the 21 years project lifespan. The high value of COE for Warri is due to its low renewable energy resource while low COE for Maiduguri is due to its high renewable energy resource. The Northern part of the country has ample renewable energy resource availability and with a strong political will, optimal utilization of these renewable resources (solar and wind) can be actualized. Researchers, Industrialists, Policy Makers and the Nigerian government should therefore seize this opportunity in developing a sustainable energy through utilization of abundant renewable energy resources in the country.

Biomass is an important renewable energy resource which primarily contributes to heating and cooling end use sectors. It is also a promising alternative source of biofuels to replace the depleting supply of fossil fuels. Surprisingly, few writers have been able to draw on the feedstock significance for oil palm empty fruit bunch (EFB) as the biomass resource for biofuels compared to the other types of biomass waste. Therefore, this paper presents a comprehensive review of EFB as a biomass resource presented in four major parts. First, the introduction covers the demand for bio-oil and describes the different kinds of feedstock, the relevance and potential of EFB biomass. Second, the characteristics of biomass are explained before it is upgraded as biofuel, drawing similarities and contrasts between EFB and other sources of biomass. Pyrolysis processes and reactors used for EFB conversion are described, and the factors affecting the bio-oil yield and quality are discussed. Major reactor parameters are summarized and reactor optimization is discussed. Third, comparison on the properties of the bio-oil vs. petroleum in transportation, power generation, and heating are compared followed by prioritizing the bio-oil properties from the most to least critical, revealing the most promising methods for upgrading. Fourth, the environmental impact, including CO2 emission, of the use of EFB as a promising renewable energy resource and a cleaner alternative fuel is recommended. This paper has comprehensively reviewed the conversion of oil palm empty fruit bunches into biofuels, including the similarities and differences between biomasses, the best reactors, its comparison with fossil fuels, and bio-oil upgrading methods. The upgrading mapping matrix is created to present the best upgrading strategies for the optimum quality of biofuels. This paper serves as a one-stop center for EFB conversion into biofuels.

The electric power sector is considered as the most important active economic sector in public life aspects including industrial, agricultural, service and recreational ones. It is known that traditional energy (fossil fuels) causes climate problems. Such problems have negative impact on the atmosphere, due to the increase in air pollution and the emergence of global sources such as solar energy as it is clean and renewable energy. As the southern Badia of Iraq has a high solar energy, it is possible to invest it in the production of electric energy and then employing it in the developmental fields in those cities (mentioned above) and even remote ones. Thus, this will lead to reducing the quantities of fossil energy consumption as well as reducing its polluting emissions to the atmosphere and its negative effects on nature, man in particular. The main objective of this study is to discover the potentials of the study area of solar radiation energy evaluating and choosing the optimal sites for the construction of the aforementioned power stations. In processing its data, the study used statistical methods to calculate the amount of solar energy reaching the surface of the study cities in the southern Badia of Iraq according to the following equation: Solar Energy = the amount of solar energy (Kilo Watt/ M2/ day) = the total solar radiation (calorie/C2/day) *constant, where the constant equals (0.0116) The study reached the most important results: Some of the study stations recorded the best optimal sites for constructing solar power stations. These are the stations of As Safawi, Busayyah, As-Salman, Al-Ma'aniya, Al-Shabajah, Al-Samawah, Najaf, Al-Nukhayb, and Al-Rutba. On the other hand, the Basra and Zubair stations recorded the lowest values for solar energy; therefore they are not ideal sites compared to other stati.

Electromagnetic light from the Sun is the largest source, and the cleanest energy available to us; extensive efforts have been dedicated to developing science and engineering solutions in order to avoid the use of fossil fuels. Solar energy transforms photons into electricity via the photovoltaic effect, generating about 20 GW of energy in the USA in 2020, sufficient to power about 17 million households. However, sunlight is erratic, and technologies to store electric energy storage are unwieldy and relatively expensive. A better solution to store energy and to deliver this energy on demand is storage in chemical bonds: synthesizing fuels such as H2, methane, ethanol, and other chemical species. In this review paper we focus on titania (TiO2) nanotubes grown through electrochemical anodization and various modifications made to them to enhance conversion efficiency; these semiconductors will be used to implement the synthesis of H2 through water splitting. This document reviews selected research efforts on TiO2 that are ongoing in our group in the context of the current efforts worldwide. In addition, this manuscript is enriched by discussing the latest novelties in this field.
